Digests

Following the Marawi Siege and global trends in counter-terrorism, Congress enacted R.A. No. 11479 to repeal the Human Security Act of 2007. The law aimed to provide a stronger legal framework to prevent, prohibit, and penalize terrorism. It introduced broader definitions of terrorist acts, empowered the Anti-Terrorism Council (ATC) to designate terrorists, and extended the period of warrantless detention. Critics immediately assailed the law, fearing it would be used to suppress dissent and target political opponents under the guise of counter-terrorism.

The Anti-Terrorism Act of 2020 is constitutional, except for: (1) the phrase in the proviso of Section 4 stating "which are not intended to cause death or serious physical harm to a person, to endanger a person's life, or to create a serious risk to public safety"; and (2) the second mode of designation in Section 25 regarding requests from other jurisdictions. The Court held that facial challenges against penal statutes are permissible only when they curtail freedom of expression and its cognate rights.

The case arises in the context of global and local movements for LGBTQI+ rights and marriage equality. While the 1987 Constitution recognizes the family as the foundation of the nation and marriage as an inviolable social institution, it does not explicitly restrict marriage by sex, gender, or sexual orientation. The LGBTQI+ community has historically faced marginalization, though pre-colonial Philippine society recognized diverse gender expressions (e.g., asog, bayoguin). The petition sought to judicially compel state recognition of same-sex marriage, bypassing legislative processes.

A facial challenge to the constitutionality of a statute requires an actual case or controversy supported by concrete facts demonstrating a direct, personal injury to the petitioner; mere self-identification as a member of a marginalized group, without proof of a specific, legally demandable right violated by the assailed law, is insufficient to establish standing or ripeness for judicial review.

Boracay Island, a premier tourist destination in Malay, Aklan, suffered severe environmental degradation due to overdevelopment, insufficient sewerage systems, illegal structures, and high fecal coliform levels in its waters. Despite being classified as agricultural and forest land, the island hosted over 18,000 tourists daily, generating 90–115 tons of solid waste daily against a local government hauling capacity of only 30 tons. The national government determined that urgent rehabilitation was necessary to prevent further ecological damage and protect public health.

The President’s issuance of Proclamation No. 475 ordering the temporary closure of Boracay Island was a valid exercise of police power under RA 10121 (Philippine Disaster Risk Reduction and Management Act of 2010) and RA 9275 (Philippine Clean Water Act of 2004), and did not constitute an unconstitutional impairment of the right to travel or deprivation of property without due process.

The case arose from the DOJ's issuance of Circular No. 41 on May 25, 2010, which consolidated previous circulars on HDOs and WLOs. Following the end of Gloria Macapagal-Arroyo's presidency, multiple criminal complaints were filed against her and her husband before the DOJ. Similarly, the Genuinos faced complaints regarding alleged diversion of PAGCOR funds. Then DOJ Secretary Leila De Lima utilized Circular No. 41 to issue WLOs and HDOs against petitioners to prevent them from leaving the country while under preliminary investigation, leading to this constitutional challenge.

DOJ Circular No. 41, s. 2010, is unconstitutional because it violates the constitutional right to travel under Section 6, Article III of the 1987 Constitution, which mandates that any impairment of this right must be authorized by a law enacted by Congress (not merely an administrative circular), and because the power to issue HDOs is an inherent judicial power that cannot be delegated to or usurped by the executive department.

The controversy arose from complaints by Tony Q. Valenciano regarding the regular holding of Roman Catholic masses at the basement of the Quezon City Hall of Justice. Valenciano alleged that this practice created a perception of judicial bias toward Catholics, caused physical inconveniences (blocked pathways, water interruptions), and constituted an unconstitutional union of Church and State. The complaints were referred to the Office of the Court Administrator (OCA) and the Executive Judges of the Quezon City Regional Trial Court (RTC) and Metropolitan Trial Court (MeTC) for evaluation.

The holding of religious rituals in public halls of justice during non-working hours does not per se violate the constitutional principle of separation of Church and State or the prohibition against appropriation of public money or property for religious benefit, provided the practice is (1) voluntary and employee-initiated; (2) conducted without expenditure of public funds for the primary benefit of the religion; (3) temporary and incidental to the public character of the space; (4) non-disruptive to public service; and (5) regulated to prevent permanent appropriation or endorsement of any particular religion.

The case arose during the 2013 midterm elections against the backdrop of the Reproductive Health Law (RA 10354) debate. The Catholic Church, through the Diocese of Bacolod, actively campaigned against the law. The dispute involves the extent of COMELEC’s regulatory power over political speech by non-candidates and the balance between electoral regulation and fundamental rights.

COMELEC lacks authority to regulate expressions made by private citizens (non-candidates) during elections under Article IX-C, Section 4 of the Constitution; size limitations on such expressions constitute unconstitutional restrictions on freedom of expression.

• Following United States v. Windsor (2013), which struck down the federal Defense of Marriage Act (DOMA), same-sex couples in multiple states filed suits challenging state-level marriage bans.
• Petitioners argued these bans violated the Fourteenth Amendment by denying them the right to marry or have out-of-state marriages recognized.
• The cases arose amid shifting public opinion and a growing number of states legalizing same-sex marriage through legislation or court rulings.

The Fourteenth Amendment’s Due Process and Equal Protection Clauses guarantee same-sex couples the fundamental right to marry, requiring states to (1) issue marriage licenses to same-sex couples and (2) recognize same-sex marriages lawfully performed in other states.

The JBC has historically implemented internal policies to streamline the selection of judicial nominees, including experience-based criteria to assess the constitutional requirement of "proven competence" for judicial appointments.

The JBC may impose additional qualification standards, such as a five-year service requirement for first-level court judges seeking promotion to second-level courts, provided these standards are reasonable, relevant to constitutional requirements of proven competence, integrity, probity and independence, and are properly published.

The case involves the tension between law enforcement efforts to combat illegal drug trafficking and the constitutional protection against unreasonable searches and seizures. The SC emphasized that while drug enforcement is crucial, it cannot justify bypassing constitutional safeguards requiring police officers themselves to observe suspicious circumstances before conducting warrantless searches.

A warrantless "stop and frisk" search is valid only if based on a police officer's personal observation of "genuine reason" to suspect criminal activity; reliance on third-party information (such as tips from informants or bystanders) without independent police observation of suspicious behavior renders the search unreasonable and unconstitutional.

• The Philippines has a long legislative history of regulating contraceptives and promoting population control, beginning with R.A. No. 4729 (1966), R.A. No. 6365 (1971), P.D. No. 79 (1972), and R.A. No. 9710 (Magna Carta for Women, 2009).
• Despite these measures, the Philippine population grew from 27 million in 1960 to over 92 million in 2010.
• The RH Law was enacted on December 21, 2012, after years of highly polarized debate between religious conservatives and progressive liberals on issues of contraception, reproductive health, and population growth control.
• The law sought to provide universal access to modern family planning methods, mandate reproductive health education in schools, require health providers to inform patients of available services, and criminalize refusals to carry out its mandates.
• Shortly after the President signed the law, challengers from various sectors filed 14 petitions and 2 petitions-in-intervention before the SC.

The RH Law (R.A. No. 10354) is NOT unconstitutional except for eight specific provisions that violate: (1) the free exercise of religion by compelling conscientious objectors to refer patients seeking reproductive health services contrary to their beliefs, under pain of criminal penalty; (2) the right to marital privacy and spousal decision-making by allowing one spouse to unilaterally decide on reproductive health procedures; (3) the natural and primary right of parents by dispensing with parental consent for minors who are already parents or have had a miscarriage; and (4) the constitutional protection of life from conception by the IRR's insertion of "primarily" in the definition of abortifacient, which is ultra vires.

R.A. 10175 was enacted to address cybercrimes such as hacking, identity theft, cybersex, child pornography, and online libel. It granted law enforcement expansive powers, including real-time data collection and executive authority to block access to data. Petitioners—lawyers, journalists, academics, and civil society groups—filed facial challenges arguing the law was overbroad, vague, and created a chilling effect on free speech and privacy.

Cyberlibel is constitutional only with respect to the original author of the post; those who merely receive and react to it (e.g., by liking, sharing, or commenting) are not liable. Additionally, the State cannot criminalize mere unsolicited commercial communications (spam), authorize warrantless real-time collection of traffic data, or allow executive agencies to block access to computer data without judicial intervention, as these constitute unconstitutional prior restraints, unreasonable searches, or abridgments of free speech.

The case involves the legislative shift in the reimbursement mechanism for the mandatory 20% discount granted to senior citizens. Under the original RA 7432 (Senior Citizens Act of 1992), private establishments could claim the discount as a tax credit (deducted from tax due after computation). RA 9257 (Expanded Senior Citizens Act of 2004) amended this to allow the discount to be claimed only as a tax deduction (deducted from gross income to arrive at taxable income), resulting in only fractional recovery (approximately 32%) of the discount amount, with the establishment absorbing the remainder.

The 20% senior citizen discount and the tax deduction scheme under RA 9257 constitute a valid exercise of the State’s police power, not a compensable taking under eminent domain, provided the regulation is not unreasonable, oppressive, or confiscatory.

“Pork Barrel” refers to lump-sum, discretionary funds historically traced to American legislative practice of directing federal budgets to local districts. In the Philippines, this evolved from Act 3044 (1922) requiring post-enactment legislator approval for public works fund distribution, to the Countrywide Development Fund (CDF) in the 1990s, and eventually the Priority Development Assistance Fund (PDAF) from 2000 onward. The system allowed individual legislators to identify local projects for funding after the General Appropriations Act (GAA) was passed. In 2013, the Commission on Audit (CoA) released a report documenting massive irregularities in PDAF utilization from 2007-2009—including ghost projects, questionable NGOs, and kickbacks—sparked by the “Napoles controversy,” prompting these petitions.

The 2013 PDAF Article and all other Congressional Pork Barrel Laws containing post-enactment measures that authorize legislators to intervene in project identification, fund release, or realignment are unconstitutional for violating the principle of separation of powers and the non-delegability of legislative power. Furthermore, the phrases “and for such other purposes as may be hereafter directed by the President” (Section 8, PD 910) and “to finance the priority infrastructure development projects” (Section 12, PD 1869, as amended) are unconstitutional for constituting undue delegation of legislative power without sufficient standards.

The case arises from the implementation of RA 9262, a landmark legislation enacted in 2004 after nine years of advocacy by women’s groups to address the pervasive violence against women and children perpetrated by intimate partners. The law defines violence against women and their children (VAWC) as a public crime, provides for protection orders (Barangay Protection Orders, Temporary Protection Orders, and Permanent Protection Orders), and imposes duties on law enforcement and judicial authorities to respond to complaints. The petitioner, a husband subjected to a TPO, mounted a facial challenge to the law’s validity, assailing its constitutionality on equal protection, due process, and separation of powers grounds.

RA 9262 is constitutional. The law’s classification limiting protection to women and children victims of violence does not violate the Equal Protection Clause because it rests on substantial distinctions (unequal power relations, statistical reality that women are the usual victims, and historical discrimination). The ex parte issuance of Temporary Protection Orders complies with due process given the exigency of preventing imminent violence, and the issuance of Barangay Protection Orders by barangay officials constitutes a valid exercise of executive, not judicial, power.

The case arises from Marikina City's efforts at urbanization and modernization under its "Clean and Green Program." The Sangguniang Panlungsod enacted Ordinance No. 192 (1994), as amended, to regulate fence construction, ostensibly to prevent the concealment of criminal activity, promote public safety, enhance aesthetic beauty, and encourage "neighborliness" by discouraging high, solid walls.

For an ordinance to be a valid exercise of police power, there must be a concurrence of a lawful subject and a lawful method; the means employed must be reasonably necessary for the accomplishment of the purpose and not unduly oppressive upon individuals. A regulation that permanently divests owners of the beneficial use of their property or amounts to a taking without just compensation is invalid.

Competing claims arose over two residential properties originally owned by Spouses Rolando and Norma Trajano. The spouses first agreed to sell the properties to Cesar Madriaga, Sr. (Madriaga, Sr.) in 1991, but later mortgaged the same to China Bank in 1995 while the titles were still in their name, leading to conflicting certificates of title and possession claims between Madriaga's successor and China Bank.

The issuance of a writ of possession under Section 7 of Act 3135 is a ministerial duty of the RTC when the purchaser at foreclosure has consolidated title, except when a third-party is actually holding the property adversely to the judgment obligor under Rule 39, Section 33; a purchaser at an execution sale who derives rights from the original owners is not such a third-party.

Following the 1986 EDSA Revolution, the Presidential Commission on Good Government (PCGG) was created to recover ill-gotten wealth accumulated by former President Ferdinand Marcos, his family, and associates. This involved complex transnational litigation involving assets hidden in Swiss foundations, dummy corporations, and foreign accounts, including Arelma, S.A., a Panamanian corporation established in 1972 to hold a Merrill Lynch account in New York.

Forfeiture proceedings under R.A. 1379 are civil in nature (actions in rem), not criminal; consequently, summary judgment under Rule 35 of the Rules of Court is available to determine forfeiture where there are no genuine issues as to any material fact, and a partial judgment on specific properties does not preclude subsequent adjudication of other properties covered by the same petition.

The case involves the enforcement of City Ordinance No. 98-012 in Naga City, which penalizes the failure to wear a crash helmet while driving a motorcycle. The incident occurred during a routine traffic enforcement operation by the Naga City Police Station.

A routine traffic stop for the issuance of a citation ticket, without intent to take the offender into custody, does not constitute a valid warrantless arrest; therefore, a warrantless search conducted during such a stop cannot be justified as "incident to a lawful arrest," and evidence obtained therefrom is inadmissible.

RA 9009 amended the Local Government Code of 1991, increasing the income requirement for conversion of municipalities to cities from P20 million to P100 million in locally generated revenue. During the 11th Congress (1998-2001), several municipalities had pending conversion bills. When RA 9009 took effect on June 30, 2001, these municipalities were caught by the new requirement. The House attempted to exempt them through Joint Resolution No. 29 (later re-adopted as Joint Resolution No. 1), but the Senate failed to act. Subsequently, during the 12th and 13th Congresses, individual Cityhood Laws were enacted for 16 municipalities, each containing an exemption clause effectively reverting to the P20 million requirement or explicitly exempting them from RA 9009. The LCP challenged these laws as unconstitutional, leading to multiple rounds of litigation and shifting majorities in the SC.

The Cityhood Laws are constitutional because the exemption clauses therein constitute valid amendments to the Local Government Code, exempting the respondent municipalities from the P100 million income requirement under RA 9009 in recognition of their distinct class and proven viability as centers of trade and commerce.

The case involves the City of Mandaluyong’s attempt to exercise eminent domain for urban land reform and low-cost housing, highlighting the procedural prerequisites for LGUs under the Local Government Code of 1991 and the proper remedies available to property owners to challenge preliminary legislative acts.

Certiorari under Rule 65 is not available to assail legislative resolutions of local Sanggunians, as these constitute policy-making functions rather than judicial or quasi-judicial acts; moreover, the power of eminent domain delegated to LGUs under Section 19 of the Local Government Code of 1991 strictly requires an ordinance, not a resolution, to authorize the local chief executive.

The dispute arose during the presidential transition from Gloria Macapagal-Arroyo to Benigno Aquino III regarding control of the National Police Commission (NAPOLCOM). President Aquino issued Executive Order No. 2 recalling appointments made by the previous administration that violated the constitutional ban on midnight appointments. The petitioner sought to retain his position by invalidating the appointments of his replacements.

An appointee holding only an acting/temporary appointment lacks the clear right to a public office necessary to maintain a quo warranto action, and the constitutional ban on midnight appointments need not be adjudicated where the case is dismissible for lack of cause of action.

Prior to R.A. 8762, R.A. 1180 (Retail Trade Nationalization Act of 1954) absolutely prohibited foreign nationals from engaging in retail trade. In 2000, Congress enacted R.A. 8762 to open the retail sector to foreign investments subject to capitalization thresholds and equity limitations, reflecting a policy shift toward regulated foreign participation in the domestic retail market.

Article II Sections 9, 19, and 20 of the 1987 Constitution are not self-executing provisions and do not impose a policy of Filipino monopoly over the economy; Section 10 of Article XII grants Congress the discretion to reserve certain areas of investments to Filipino citizens or to allow foreign participation when the national interest does not require reservation.

The case arises from the intersection of the party-list system—a constitutional mechanism designed to afford marginalized and underrepresented sectors representation in Congress—and the constitutional rights of LGBT individuals. The dispute tests the limits of COMELEC's discretion in screening party-list applicants, particularly whether it may invoke religious doctrine or "public morals" to exclude groups based on sexual orientation.

Moral disapproval, without more, is not a sufficient governmental interest to justify the exclusion of homosexuals from participation in the party-list system.
The morality referred to in law is public and necessarily secular, not religious; governmental reliance on religious justification is inconsistent with the constitutional policy of neutrality.

In 1999, the Senate Committees on Trade and Commerce and on Justice and Human Rights conducted joint hearings on the legality of parking fee collection by shopping malls following public complaints. The Committees issued Senate Committee Report No. 225, concluding that the practice violated the National Building Code and recommending that the OSG institute legal action to enjoin the collection of fees and exact refunds from mall owners.

The National Building Code and its Implementing Rules do not impose an obligation on shopping mall operators to provide parking spaces free of charge; absent express statutory language, such obligations cannot be presumed under Article 1158 of the Civil Code, and any prohibition against the collection of parking fees would constitute a taking of private property without just compensation.

The case arises from the City of Manila's continuing efforts to regulate establishments in the Ermita-Malate area perceived as venues for prostitution and illicit activities. Following the SC decision in City of Manila v. Laguio (which nullified a total ban on motels and inns in the area), the City enacted Ordinance No. 7774 as a regulatory middle-ground—targeting specific business practices (short-time rates) rather than imposing a wholesale prohibition. The ordinance represents the tension between government power to regulate morality and individual constitutional liberties.

A local ordinance prohibiting short-time rates in lodging establishments is unconstitutional when it constitutes an arbitrary interference with the fundamental right to liberty (including privacy) and property, failing the test of substantive due process because the means employed (blanket ban) are not reasonably necessary to the stated legitimate end (curbing immorality) and are unduly oppressive of private rights.

In 2005, wiretapped recordings allegedly containing conversations between President Gloria Macapagal-Arroyo and COMELEC Commissioner Virgilio Garcillano ("Hello Garci" tapes) surfaced, triggering legislative investigations in both Houses of Congress regarding alleged election fraud and wiretapping activities.

The Senate is not a continuing body with respect to the conduct of its business; therefore, it must publish its Rules of Procedure Governing Inquiries in Aid of Legislation at the start of each Congress (or after every expiry of the term of twelve Senators) to comply with the constitutional requirement of Section 21, Article VI. Publication must be in the Official Gazette or a newspaper of general circulation; internet or booklet publication is insufficient.

The case stems from decades of armed conflict in Mindanao involving the Moro Islamic Liberation Front (MILF). In 2001, the GRP and MILF signed the Tripoli Agreement on Peace, which outlined three aspects: Security, Rehabilitation, and Ancestral Domain. After years of negotiations, the parties initialed the MOA-AD on July 27, 2008, scheduled for formal signing on August 5, 2008. The MOA-AD proposed the creation of a BJE with "associative" status, extensive territorial jurisdiction including internal and territorial waters, and powers approximating statehood (e.g., treaty-making, internal security force), contingent upon amendments to the Constitution and existing laws.

The Executive branch, through the GRP Peace Panel, exceeded its constitutional authority by negotiating and initialing the MOA-AD, which effectively guaranteed amendments to the Constitution and created a juridical entity with powers and attributes incompatible with the constitutional framework of national sovereignty and territorial integrity.

The case stems from the anomalous purchase of a hemoanalyzer (particle counter) by the Eastern Visayas Regional Medical Center (EVRMC) in 1996, where documents indicated acceptance of delivery in December 1996 despite the equipment actually being delivered in April 1997, suggesting falsification of public documents.

The Office of the Ombudsman exercises full administrative disciplinary authority under the 1987 Constitution and RA 6770, which includes the power to investigate, determine administrative liability, impose penalties (such as suspension or dismissal), and compel the head of the agency to implement such penalties; orders for preventive suspension issued by the Ombudsman are immediately effective and executory under Section 27(1) of RA 6770 and are not stayed by the filing of a motion for reconsideration.

In June 2005, amidst political turmoil following the 2004 elections, alleged wiretapped recordings of conversations between President Gloria Macapagal-Arroyo and COMELEC Commissioner Virgilio Garcillano surfaced. These "Garci Tapes" purportedly contained discussions about manipulating election results. Press Secretary Ignacio Bunye initially confirmed then retracted the authenticity of the tapes. Various individuals, including former presidential counsel Alan Paguia and former NBI Deputy Director Samuel Ong, released versions of the tapes to the public and media.

Government threats of criminal prosecution or administrative sanctions (license revocation) against media for airing specific content constitute content-based prior restraints subject to strict scrutiny under the clear and present danger rule; such restraints are presumptively invalid unless the government proves a substantive evil that is grave and imminent, and the restriction is narrowly tailored.

The case involves the implementation of the Expanded Senior Citizens Act of 2003 (RA 9257), which amended the previous Senior Citizens Act (RA 7432). The amendment significantly altered the reimbursement mechanism for the mandatory 20% discount from a tax credit scheme (full reimbursement) to a tax deduction scheme (partial reimbursement), shifting a substantial portion of the financial burden to private establishments.

A law requiring private establishments to grant discounts to senior citizens, reimbursable via tax deduction rather than full tax credit, is a valid exercise of police power and does not violate the constitutional prohibition against taking private property without just compensation; property rights must yield to the primacy of police power when the legislature determines that conditions demand it for the general welfare.

The case arose during the Arroyo administration's push for Charter Change ("Cha-Cha"). The "Sigaw ng Bayan" movement, led by Lambino and Aumentado, sought to utilize the people's initiative provision (Section 2, Article XVII) to bypass Congress and directly propose amendments shifting the Philippines to a unicameral-parliamentary system. This followed the 1997 precedent in Santiago v. COMELEC, where the Court declared RA 6735 (the Initiative and Referendum Act) "incomplete, inadequate, or wanting in essential terms and conditions" to implement constitutional initiatives.

An initiative to amend the Constitution must strictly comply with Section 2, Article XVII: (1) the full text of the proposed amendments must be shown to the people before they sign, and the petition must contain such full text (either on the face or attached with an indication thereof); and (2) the people's initiative is limited to amendments only; revisions (such as a fundamental change in the structure of government) must be proposed by Congress or a Constitutional Convention.

The case involves a conflict between the State's interest in regulating morality and marriage (as expressed in the Civil Service Law and the Revised Penal Code) and an individual's right to free exercise of religion. The respondent, a court interpreter and a Jehovah's Witness, lived with a man who was legally married to another woman. Under her congregation's tenets, they executed a "Declaration of Pledging Faithfulness," which morally binds them as a couple within their faith despite legal impediments to marriage. The complainant, a private citizen, viewed this as tarnishing the judiciary's image.

In resolving claims involving religious freedom, the Philippine Constitution adopts the benevolent neutrality-accommodation framework (allowing both mandatory and permissive accommodations), and the compelling state interest test is the proper standard to determine if the State can override a sincerely held religious belief; absent proof of a compelling state interest and the use of the least restrictive means, a religious exemption from a neutral law of general application may be granted.

The case involves the interpretation of Republic Act No. 2000 (Limited Access Highway Act of 1957), which originally granted the Department of Public Works and Communications authority over limited access facilities. The dispute arose from the DPWH's issuance of department orders declaring North and South Luzon Expressways and the Manila-Cavite Toll Expressway as limited access facilities and banning motorcycles thereon, raising questions of which executive department—DPWH or DOTC—possesses the regulatory authority over access to these highways following various reorganizations of the executive branch.

The authority to regulate, restrict, or prohibit access to limited access facilities, including the determination of who may be permitted entry, belongs to the DOTC, not the DPWH. An agency cannot delegate a power it does not possess; thus, the DPWH cannot delegate regulatory authority to the Toll Regulatory Board (TRB) where such authority properly resides with the DOTC.

On February 24, 2006, President Gloria Macapagal-Arroyo issued PP 1017 citing a conspiracy among military adventurists (Magdalo Group), communist rebels (NPA), and political opposition to overthrow the government. The proclamation declared a "state of national emergency" and commanded the AFP to maintain law and order, prevent lawless violence, and enforce obedience to all laws and decrees. G.O. No. 5 was issued the same day, directing the AFP and PNP to suppress "acts of terrorism and lawless violence." The President lifted PP 1017 on March 3, 2006 via PP 1021, but not before alleged constitutional violations were committed by law enforcement.

• PP 1017 is constitutional insofar as it constitutes a call by the President on the AFP to prevent or suppress lawless violence under Section 18, Article VII.
• PP 1017 is unconstitutional insofar as it: (1) authorizes the President to promulgate decrees with the force of law; (2) purports to authorize the takeover of privately-owned public utilities without legislation; and (3) is construed to permit warrantless arrests, searches, and prior restraint on the press not justified by the Constitution.
• G.O. No. 5 is constitutional as it provides a standard ("necessary and appropriate actions... to suppress lawless violence"), but the phrase "acts of terrorism" is unconstitutional and deemed deleted for being void for vagueness.
• Illegal acts committed pursuant to PP 1017 and G.O. No. 5 (warrantless arrests of David and Llamas, dispersal of rallies, raid on Daily Tribune) are unconstitutional as applied.

The case arose from a conflict between Segundo Lim and broadcast journalist Cirse "Choy" Torralba, wherein Lim alleged that Torralba was making scurrilous attacks against him and his family over the airwaves. Lacking access to radio time to respond, Lim resorted to a paid newspaper advertisement to publicize Torralba's own criminal records.

In criminal libel cases involving public figures, conviction requires proof beyond reasonable doubt of "actual malice"—defined as knowledge that the statement was false or reckless disregard for whether it was true or not—and Article 354 of the Revised Penal Code (presuming malice in every defamatory imputation even if true) must be construed in light of this constitutional standard requiring proof of actual malice for public figures.

The dispute arose from a will purportedly executed by Vicente Lee, Sr. in 1965, which bequeathed his entire estate to his wife Lim Hock Lee and a parcel of land to two other children, allegedly to the exclusion of complainant Manuel L. Lee. Complainant contested the will’s authenticity, alleging his father never executed it and that the signatures of the testator and witnesses were forged.

A notary public, especially a lawyer, is bound to strictly observe the mandatory formalities of the Notarial Law and the Civil Code regarding the execution of wills, including the requirement of three credible witnesses, the exhibition of current residence certificates, and proper entries in the notarial register; gross negligence in these duties constitutes professional misconduct warranting suspension and revocation of commission.

• Bowers v. Hardwick (1986) upheld Georgia’s sodomy law, finding no constitutional right to engage in homosexual sodomy.
• Texas § 21.06(a) uniquely criminalized same-sex sodomy while permitting identical conduct between opposite-sex couples.
• Growing national trend decriminalizing sodomy (only 13 states retained sodomy laws by 2003; only 4 targeted same-sex conduct exclusively).

The Due Process Clause of the Fourteenth Amendment protects the liberty of adults to engage in private, consensual intimate conduct without government intrusion. Laws criminalizing such conduct between same-sex adults violate this fundamental liberty interest.

The case arises from the prosecution of the highest-ranking official to be charged under the Plunder Law. Following the events of EDSA II and the assumption of the presidency by Gloria Macapagal-Arroyo, the Office of the Ombudsman filed multiple informations against former President Estrada, including one for plunder involving an aggregate amount of P4,097,804,173.17 allegedly acquired through a combination or series of overt criminal acts (jueteng money, tobacco excise tax diversion, GSIS/SSS stock manipulation, and unexplained wealth).

R.A. No. 7080 (The Plunder Law), as amended by R.A. No. 7659, is constitutional. It is not void for vagueness; it contains ascertainable standards and well-defined parameters. Section 4 is a procedural rule of evidence, not a substantive element that eliminates the requirement of proving each component act beyond reasonable doubt. Plunder is a malum in se crime requiring mens rea, and the statute maintains the presumption of innocence and the reasonable doubt standard.

During the martial law regime, President Ferdinand Marcos issued P.D. No. 579, rationalizing sugar exports by authorizing the Philippine Exchange Co., Inc. (PHILEX) to purchase export sugar and directing that profits from such sales be remitted to a special fund of the National Government. The decree authorized PNB to finance PHILEX's purchases. Sugar planters, including the Mirasols, were required to sell their export sugar to the government through this scheme at prices fixed by government agencies (P180.00 per picul for crop years 1973-1974 and 1974-1975), significantly below world market prices.

In any action involving the validity of a statute, presidential decree, or regulation, mandatory notice to the Solicitor General is required under Rule 64, Section 3 of the Rules of Court, and the failure to give such notice deprives the lower court of authority to pass upon the constitutional question; furthermore, courts will not reach constitutional issues where the controversy can be settled on other grounds such as the law on agency and legal compensation.

An alarming increase in violent crimes (robberies, kidnappings, carnappings) in Metro Manila, perpetrated by organized syndicates including active and former police/military personnel whose capabilities exceeded those of local police.

The President’s power to call out the armed forces to prevent or suppress lawless violence under Section 18, Article VII of the Constitution is fully discretionary and not subject to judicial review of the sufficiency of the factual basis, except to determine whether there has been grave abuse of discretion amounting to lack or excess of jurisdiction; mere deployment of military personnel to assist civilian law enforcement in a supportive capacity, without exercising regulatory, proscriptive, or compulsory authority, does not violate the civilian supremacy clause or the prohibition against appointing military personnel to civilian positions.

International School, Inc. operates under Presidential Decree 732 as a domestic educational institution primarily serving dependents of foreign diplomatic personnel. The School maintains a faculty comprising both foreign nationals recruited abroad and local residents (including Filipinos and some foreigners domiciled in the Philippines), classified respectively as "foreign-hires" and "local-hires."

Employees performing substantially equal work with equal qualifications, skill, effort, and responsibility under similar conditions must receive equal compensation regardless of nationality or point-of-hire classification; salary differentials based on "dislocation" or limited tenure are invalid where such factors are already offset by other benefits, and labor contracts containing discriminatory wage provisions are unenforceable as contrary to public policy.

In preparation for the 1995 national elections, the Commission on Elections (COMELEC) promulgated Resolution No. 2772. Section 2 of the resolution mandated that COMELEC "shall procure free print space" of not less than one-half page in newspapers of general circulation for use as "Comelec Space" to disseminate candidate information and vital election data. In implementation, COMELEC sent directive letters to various newspaper publishers, members of the PPI, ordering them to provide the free space. The PPI, a non-stock, non-profit organization of newspaper and magazine publishers, filed a petition for certiorari and prohibition, challenging the resolution's constitutionality.

A government agency cannot compel private newspaper publishers to donate print space for public election purposes, as such compulsion constitutes a taking of private property for public use without just compensation, violating the constitutional guarantee against eminent domain without due process.

The PCSO, empowered by its charter to conduct charity sweepstakes and lotteries, sought to establish a nationwide on-line lottery system to increase revenues. It issued a Request for Proposal (RFP) for a contractor to build and maintain the system at its own expense, with the PCSO leasing the facilities. The Philippine Gaming Management Corporation (PGMC), a domestic corporation with significant foreign equity, was awarded the contract. A "Contract of Lease" was executed on December 1, 1993, stipulating that PGMC would build, furnish, and maintain the lottery facilities, bearing all costs and risks, in exchange for a "rental fee" of 4.9% of gross receipts. The contract contained provisions detailing the rights and obligations of both parties.

A contract that, in substance, establishes a joint venture or collaboration between the PCSO and a private entity for the operation of a lottery violates the explicit statutory prohibition in Section 1(B) of R.A. No. 1169, as amended, and is therefore invalid, regardless of its nominal designation as a lease.

The Republic initiated expropriation proceedings for the widening and concreting of the Nabua-Bato-Agos Section of the Philippine-Japan Highway Loan road. The legal dispute centered on the method for determining just compensation: whether based on the fair market value demanded by landowners or on the statutory valuation fixed by PD 76 (as amended) and related decrees.

A judicial declaration of unconstitutionality of a statute applies retroactively to pending cases where the rights of the parties remain unresolved, as an unconstitutional law is a total nullity that is deemed never to have existed, absent exceptional circumstances such as vested rights or fait accompli situations.

Prior to this case, Gerona v. Secretary of Education (1959) and Balbuna v. Secretary of Education (1960) upheld the expulsion of Jehovah's Witness students under R.A. No. 1265 (Flag Salute Law), ruling that the flag is a secular symbol and the ceremony a patriotic exercise, not religious worship. These rulings were later codified in the Administrative Code of 1987 (EO 292). By 1989-1990, DECS officials in Cebu enforced these precedents through expulsion orders against Jehovah's Witness students who refused to salute the flag, sing the anthem, or recite the pledge.

Students may not be expelled from public schools for refusing to participate in flag ceremonies based on sincere religious beliefs, provided they conduct themselves quietly and respectfully without disrupting the proceedings; compulsory participation constitutes an unconstitutional infringement on freedom of religion and free speech.

Mikael Malmstedt, a Swedish tourist, was traveling by bus from Sagada to Baguio City. On the same day, the commanding officer of the Narcotics Command (NARCOM) received information that a Caucasian coming from Sagada was carrying prohibited drugs. Acting on this intelligence and persistent reports of drug trafficking on that route, NARCOM officers established a temporary checkpoint. When the bus carrying Malmstedt was stopped, officers noticed a bulge on his waist. Malmstedt's failure to produce his passport or identification upon request heightened their suspicion, leading to a search that revealed hashish on his person and in his luggage.

A warrantless search is valid as an incident to a lawful arrest when officers have probable cause to believe the person is committing an offense, based on specific, contemporaneous intelligence and the person's own suspicious conduct that frustrates identification.

During the Marcos regime, petitioners participated in a demonstration supporting the Alliance of Concerned Transport Organization (ACTO) jeepney strike. Their subsequent arrest and prosecution occurred in a context where the executive exercised broad powers of preventive detention through PDAs, raising concerns about the weaponization of criminal process against dissenters.

Criminal prosecution may be permanently enjoined when it constitutes persecution undertaken in manifest bad faith, characterized by sham preliminary investigations and deliberate manipulation of legal processes to violate constitutional rights such as due process and the right to bail.

The case arises from the government's effort to regulate admission to medical schools and upgrade the quality of medical education through the NMAT. Following widespread concerns about the competence of medical practitioners and the need to protect public health, the DECS implemented selectivity in admissions to prevent the infiltration of incompetents into the medical profession.

The "three-flunk rule" prohibiting a student from taking the NMAT after three successive failures is a valid exercise of police power that does not violate due process, equal protection, or the constitutional right to education.

The case arose during an "Anti-Smut Campaign" initiated by the Mayor of Manila targeting allegedly obscene, pornographic, and indecent reading materials sold in public areas, particularly along sidewalks in the University Belt.

Warrantless seizures of allegedly obscene publications by police authorities, without a prior judicial determination of obscenity through a search warrant based on probable cause, constitute unreasonable searches and seizures and violate due process; the State bears the burden of proving "clear and present danger" to justify prior restraint on speech, and mere police suspicion of obscenity does not authorize summary confiscation.

Ferdinand Marcos was deposed from the presidency in February 1986 through the non-violent "People Power" revolution and forced into exile in Hawaii. Corazon C. Aquino assumed the presidency under a revolutionary government. The period following Marcos’s ouster witnessed multiple coup attempts (including the 1986 Manila Hotel coup and the 1987 Honasan coup), communist insurgency, Mindanao secessionist movements, and economic devastation attributed to foreign debt and alleged plunder of national wealth by Marcos and his cronies. Despite the ratification of the 1987 Constitution, the government faced continued destabilization efforts by Marcos loyalists. In 1989, Marcos, reportedly on his deathbed, expressed his wish to return to the Philippines to die. President Aquino refused, determining that his return would endanger national security and economic recovery.

The President possesses residual executive power, as steward of the people and protector of the peace, to bar the return of nationals when such return poses a threat to national security, public safety, and general welfare; this determination is a political question reviewable only for grave abuse of discretion.
