ISAAA vs. Greenpeace Southeast Asia

The precautionary principle mandates the permanent enjoinment of GMO field trials and the nullification of administrative regulations that fail to operationalize international biosafety standards where scientific uncertainty exists regarding serious and irreversible harm to the environment and human health, requiring regulatory agencies to implement the National Biosafety Framework's provisions on risk assessment, public participation, and environmental impact assessment prior to approving any release of genetically modified organisms into the environment.

The dispute arose from field trials of "Bt talong," an eggplant genetically engineered to produce the Cry1Ac protein toxic to the fruit and shoot borer (Leucinodes orbonalis), conducted by the University of the Philippines Los Baños (UPLB) and the International Service for the Acquisition of Agri-Biotech Applications, Inc. (ISAAA). The Philippines, a megadiverse country and signatory to the Cartagena Protocol on Biosafety, established the National Biosafety Framework (NBF) under Executive Order No. 514 to regulate modern biotechnology. The Department of Agriculture issued DAO 08-2002 to govern the importation and release of GMOs, requiring risk assessments and biosafety permits from the Bureau of Plant Industry (BPI). Respondents—environmental organizations, farmers' groups, scientists, and public officials—challenged the field trials alleging violations of the constitutional right to a balanced and healthful ecology due to insufficient safety data, risk of genetic contamination, and inadequate public consultation.

• The Bt Talong Project: A collaborative research and development project involving UPLB, ISAAA, the University of the Philippines Mindanao Foundation, Inc., Maharastra Hybrid Seed Company (MAHYCO) of India, Cornell University, and the Agricultural Biotechnology Support Project II (ABSPII) of USAID. The project involved inserting crystal toxin genes from Bacillus thuringiensis (Bt) into the eggplant genome to produce the Cry1Ac protein, toxic to lepidopteran larvae such as the fruit and shoot borer.

• Regulatory Approvals: Following contained experiments completed in 2009 and certified by the National Committee on Biosafety of the Philippines (NCBP), the Bureau of Plant Industry (BPI) issued Biosafety Permits to UPLB on March 16, 2010 and June 28, 2010 for multi-locational field trials in Kabacan (North Cotabato), Sta. Maria (Pangasinan), Pili (Camarines Sur), Bago Oshiro (Davao City), and Bay (Laguna).

• Allegations of Violations: Respondents alleged that the field trials violated their constitutional right to health and a balanced ecology because: (1) no Environmental Compliance Certificate (ECC) was secured under the Philippine Environmental Impact Statement System (PEISS); (2) Bt talong is presumed harmful under DAO 08-2002 with no independent, peer-reviewed safety studies; (3) studies indicated potential allergenicity and toxicity of Cry1Ac protein; (4) field trials risked contamination of non-GM eggplant varieties and wild relatives through cross-pollination (eggplant being 48% insect-pollinated); (5) the 200-meter isolation distance was insufficient to prevent pollen flow by honeybees capable of flying four kilometers; and (6) mandatory public consultation under the Local Government Code and free, prior, and informed consent requirements were not complied with.

• Scientific Uncertainty and Global Debate: Expert testimony through the "hot-tub" method revealed diametrically opposed scientific views. Proponents cited 50 years of safe Bt pesticide use and 14 years of Bt crop consumption without documented harm, emphasizing the protein's specificity to target insects. Opponents highlighted studies showing Cry1Ac binding to mammalian intestinal cells, potential for allergenicity, development of pest resistance, harm to non-target organisms, and irreversibility of genetic contamination. The Court noted the global scientific controversy, including the retraction and republication of Professor Gilles-Eric Seralini's study linking GM corn to tumors in rats, and the absence of epidemiological studies on human health effects.

• Regulatory Framework Deficiencies: The Department of Environment and Natural Resources-Environmental Management Bureau (DENR-EMB) admitted lack of competence and resources to evaluate GMO field trials under the PEISS, treating them as "unclassified" projects. The field trials proceeded without Environmental Impact Statements (EIS) or ECCs, and public participation was limited to posting notices rather than meaningful consultation as required by the National Biosafety Framework (NBF) under EO 514.

• Mootness and Academic Freedom: ISAAA and UPLB argued that the petitions should be dismissed as moot since field trials terminated in August 2012. UPLB asserted that the injunction violated constitutional academic freedom and scientific progress, claiming the field trials were controlled experiments essential for generating safety data.

• Compliance with Regulatory Requirements: Petitioners maintained strict compliance with DAO 08-2002, including risk assessments by independent Scientific and Technical Review Panels (STRP), Institutional Biosafety Committee approvals, and public information campaigns. They argued that field trials are distinct from commercial release and do not require ECCs under PEISS.

• Scientific Consensus on Safety: ISAAA presented meta-analyses of 1,783 studies concluding no significant hazards from GE crops, citing approvals by the European Food Safety Authority (EFSA), World Health Organization (WHO), and other regulatory bodies. They criticized the Seralini study as methodologically flawed and retracted, and argued that the Cry1Ac protein's safety was established through history of safe use.

• Political Question and Exhaustion of Remedies: Petitioners contended that challenges to the sufficiency of biosafety regulations constitute political questions for the legislative and executive branches. They argued respondents failed to exhaust administrative remedies under DAO 08-2002 (Sections 8[G] and 8[P]) allowing submission of comments and revocation of permits.

• Lack of Evidence of Harm: EMB/BPI/FPA asserted that respondents failed to prove actual or imminent environmental damage of the magnitude required for a writ of kalikasan (affecting two or more cities or provinces), emphasizing that field trials were contained and no Bt talong entered the food supply.

• Legal Standing and Intergenerational Rights: Respondents invoked Oposa v. Factoran to assert standing as citizens representing present and future generations' constitutional right to a balanced and healthful ecology, citing the Rules of Procedure for Environmental Cases allowing citizen suits.

• Precautionary Principle Application: Respondents argued that scientific uncertainty regarding long-term health effects, allergenicity, and ecological impacts of Bt talong—particularly in a megadiverse country like the Philippines—triggered the precautionary principle under Rule 20 of the Rules of Procedure for Environmental Cases and the Cartagena Protocol on Biosafety. They emphasized that genetic contamination is irreversible and that the burden of proof should shift to proponents to demonstrate safety.

• Inadequacy of DAO 08-2002 and NBF Non-Implementation: Respondents contended that DAO 08-2002 violated EO 514 (National Biosafety Framework) by failing to require Environmental Impact Assessments, meaningful public participation (beyond notice-posting), and socio-economic impact assessments. They highlighted that the NBF mandates precautionary, transparent, and participatory decision-making, which the BPI circumvented.

• Threat of Irreversible Harm: Citing global contamination incidents (StarLink corn, Liberty Link rice, GE flax), respondents demonstrated that field trials inevitably lead to genetic contamination of non-GM crops and wild relatives, threatening the Philippines' status as a center of origin for eggplant diversity. They cited studies showing Cry1Ac protein immunogenicity in mammals and potential toxicity to non-target organisms.

• Exhaustion of Administrative Remedies Inapplicable: Respondents argued that DAO 08-2002 provides no appeal mechanism for stakeholders to challenge permit approvals, only procedures for applicants to appeal denials, rendering administrative remedies inadequate.

• Legal Standing: Whether respondents possess locus standi to file the petition for writ of kalikasan.
• Mootness: Whether the case has been rendered moot by the termination of field trials.
• Exhaustion of Administrative Remedies: Whether respondents were required to exhaust administrative remedies before filing suit.
• Environmental Impact Assessment: Whether GMO field trials are covered by the Philippine Environmental Impact Statement System (PEISS) requiring an Environmental Compliance Certificate.
• Evidence of Harm: Whether respondents proved damage or threat of damage to human health and the environment sufficient to warrant the issuance of a writ of kalikasan.
• Precautionary Principle: Whether the precautionary principle applies to justify the permanent enjoinment of Bt talong field trials.
• Validity of DAO 08-2002: Whether Department of Agriculture Administrative Order No. 08, Series of 2002 is valid and consistent with the National Biosafety Framework under EO 514.

• Legal Standing: Respondents possess legal standing as citizens under Section 5, Rule 2 of the Rules of Procedure for Environmental Cases, which allows citizen suits in environmental cases. Following Oposa v. Factoran, citizens may sue on behalf of themselves and future generations to enforce the constitutional right to a balanced and healthful ecology, constituting intergenerational responsibility.

• Mootness: The case falls under the exceptions to the mootness doctrine: (1) the issue involves paramount public interest affecting the constitutional right to health and balanced ecology; and (2) the controversy is capable of repetition yet evading review, as proponents intended to proceed to commercial propagation and similar field trials may be conducted for other GMOs.

• Exhaustion of Administrative Remedies: The doctrine does not apply where strong public interest is involved and no adequate administrative remedy exists. DAO 08-2002 provides no mechanism for stakeholders to appeal the issuance of biosafety permits, rendering administrative remedies illusory.

• Environmental Impact Assessment: GMO field trials constitute environmentally critical projects under the PEISS and Section 5.3 of EO 514 (NBF), requiring Environmental Impact Statements and Compliance Certificates prior to implementation. The DENR-EMB's failure to classify GMOs under Proclamation No. 2146 does not excuse non-compliance, as EO 514 explicitly mandates coordination between agencies to determine EIA applicability.

• Evidence of Harm: The evidence establishes threats of serious and irreversible harm: (1) genetic contamination of the Philippines' rich biodiversity and centers of origin for eggplant; (2) potential health risks including allergenicity and toxicity of Cry1Ac protein; and (3) ecological imbalances affecting non-target organisms and pest resistance. The global scientific debate and lack of epidemiological studies on human health effects confirm scientific uncertainty.

• Precautionary Principle: The principle applies where three conditions converge: (1) uncertainty regarding causal links between human activity and environmental effect; (2) possibility of irreversible harm; and (3) possibility of serious harm. The constitutional right to a balanced and healthful ecology shall be given the benefit of the doubt. The burden of proof shifts to GMO proponents to demonstrate absence of harm, which they failed to discharge.

• Validity of DAO 08-2002: DAO 08-2002 is declared null and void for failure to operationalize the National Biosafety Framework (EO 514), specifically regarding: (1) mandatory application of the precautionary approach; (2) meaningful public participation beyond notice-posting; (3) requirement for Environmental Impact Assessments; and (4) consideration of socio-economic, ethical, and cultural impacts. The Order's provisions on risk assessment and public consultation are insufficient under the NBF and international biosafety standards.

• Precautionary Principle in Environmental Adjudication: Defined under Rule 20 of the Rules of Procedure for Environmental Cases, the principle requires courts to resolve doubts in favor of the constitutional right to a balanced and healthful ecology when scientific uncertainty exists regarding causal links between human activity and environmental harm. Application requires: (1) considerable scientific uncertainties; (2) scientifically reasonable scenarios of harm; (3) inability to reduce uncertainties without increasing ignorance of other factors; (4) potential harm that is serious, irreversible, or morally unacceptable; and (5) need for immediate action to prevent greater difficulty or cost later. The principle shifts the burden of evidence from those likely to suffer harm to those desiring to change the status quo.

• Intergenerational Responsibility and Standing: The constitutional right to a balanced and healthful ecology is assumed to exist from the inception of mankind and carries correlative duties to preserve the environment for future generations. Citizens, including minors, may sue as representatives of present and succeeding generations to enforce environmental rights, relaxing traditional standing requirements.

• Substantial Equivalence and GMO Risk Assessment: The concept that a GM food or organism is as safe as its conventional counterpart if genetic modification has not resulted in intended or unintended alterations in relevant nutrients and toxicants. However, establishing substantial equivalence is not itself a safety assessment but a pragmatic tool requiring the latest scientific methods and comprehensive testing to detect unsuspected health risks.

• National Biosafety Framework Implementation: Executive Order No. 514 mandates that biosafety decisions incorporate the precautionary approach, public participation, transparency, and consideration of socio-economic, ethical, and cultural impacts. Administrative regulations (DAO 08-2002) that fail to operationalize these mandatory principles are invalid.

• "When there is a lack of full scientific certainty in establishing a causal link between human activity and environmental effect, the court shall apply the precautionary principle in resolving the case before it. The constitutional right of the people to a balanced and healthful ecology shall be given the benefit of the doubt." — Rule 20, Section 1, Rules of Procedure for Environmental Cases, as applied by the Court.

• "Introducing a genetically modified plant in our intricate world of plants by humans certainly appears to be an ecologically imbalancing act. The damage that it will cause may be irreparable and irreversible." — Court of Appeals, quoted with approval by the Supreme Court.

• "The precautionary principle shifts the burden of evidence of harm away from those likely to suffer harm and onto those desiring to change the status quo." — Annotation to the Rules of Procedure for Environmental Cases, cited by the Court.

• "The release of a GM crop into its area of origin or diversity has far greater ramifications and potential for negative impact than for other species. To justify this, there needs to be extraordinarily compelling reasons and only when other choices are not available." — Technical Expert Committee (India), cited by the Court.

• Oposa v. Factoran, Jr., G.R. No. 101083 (1993) — Established the doctrine of intergenerational responsibility, holding that citizens may sue on behalf of future generations to protect the right to a balanced and healthful ecology, and liberalized standing requirements in environmental cases.
