Republic of the Philippines vs. Winston Brian Chia Lao et al.

Rule 108 of the Rules of Court is the proper remedy to change or annotate the nationality of a child’s parents in the certificate of live birth to reflect the parents’ subsequent naturalization as Filipino citizens; the minor children of a person naturalized under Letter of Instructions No. 270 and Presidential Decree Nos. 836 and 923 follow the acquired Filipino citizenship of their mother and need not first undergo a separate proceeding before the Special Committee on Naturalization.

Lao Kian Ben and Chia Kong Liong, both Chinese nationals, were the parents of Jon Nicholas, Winston Brian, and Christopher Troy Chia Lao. Lao Kian Ben applied for naturalization under Letter of Instructions No. 270, and his application was granted under Presidential Decree No. 923; Chia Kong Liong was likewise conferred Philippine citizenship under Presidential Decree No. 923. The dispute concerns the legal effect of those naturalization decrees, read with Section 15 of Commonwealth Act No. 473 and Presidential Decree No. 836, on the civil-register entries of the children’s parents’ nationality, which had been recorded as “Chinese” at birth.

Lao Kian Ben and Chia Kong Liong married on October 14, 1962 at the Our Lady of Lourdes Sta. Teresita Parish, Quezon City. They are the parents of Jon Nicholas, born on November 22, 1966; Winston Brian, born on December 3, 1968; and Christopher Troy, born on March 19, 1973. In the respective Certificates of Live Birth of Jon Nicholas, Winston Brian, and Christopher Troy issued by the now defunct National Statistics Office, the indicated nationality of both Lao Kian Ben, as father, and Chia Kong Liong, as mother, was “Chinese.”

Thereafter, Lao Kian Ben applied for naturalization as a Filipino citizen before the Special Committee on Naturalization, pursuant to Letter of Instructions No. 270. The application was granted and Lao Kian Ben was conferred Philippine citizenship under Presidential Decree No. 923. He took his Oath of Allegiance to the Republic of the Philippines on June 15, 1976 and was issued his Certificate of Naturalization on the same day. Chia Kong Liong, being the wife of Lao Kian Ben, was likewise conferred Philippine citizenship pursuant to Presidential Decree No. 923. She was issued a Certificate of Naturalization on January 24, 1979 and, on the same day, took her Oath of Allegiance to the Republic of the Philippines.

Meanwhile, Jon Nicholas, Winston Brian, and Christopher Troy—all born and raised in the Philippines—studied in Philippine schools. Jon Nicholas went to Xavier School for his elementary and high school education, and attended the University of Santo Tomas for college. Winston Brian and Christopher Troy attended Xavier School, as well as the Jubilee Christian Academy for their grade school education, and attended the Philippine Institute of Quezon City for secondary school. Winston Brian studied at the Philippine School of Business Administration, while Christopher Troy studied at the University of Santo Tomas. All three married Filipino citizens and raised their children in the Philippines.

Winston Brian and Christopher Troy filed a Petition, later an Amended Petition, for correction of entry in their respective Certificates of Live Birth before the Regional Trial Court of Manila. They contended that the nationality of their parents, Lao Kian Ben and Chia Kong Liong, should be changed from “Chinese” to “Filipino,” considering that their parents had already been naturalized as Filipino citizens pursuant to Philippine laws. The Manila trial court set the Amended Petition for hearing, ordered publication, and directed the Local Civil Registrar of Manila and all interested persons to file opposition. The Office of the Solicitor General was notified, and the Office of the City Prosecutor of Manila appeared. After compliance with the jurisdictional requirements and with no opposition, the trial court received evidence. Jon Nicholas, for his part, filed a Petition, later amended, before the Regional Trial Court of Quezon City, raising the same claim that his parents’ naturalization should result in a change in their nationality as entered in his Certificate of Live Birth. The Quezon City trial court likewise set the case for hearing, ordered publication, and served copies on the Office of the Solicitor General, Local Civil Registrar of Quezon City, Quezon City Prosecutor’s Office, and National Statistics Office. Jon Nicholas presented documentary evidence to prove compliance with the jurisdictional facts. Both trial courts found that the respondents complied with Rule 108 and proved that they are the legitimate children of Lao Kian Ben and Chia Kong Liong, former Chinese nationals who became naturalized Filipinos while the respondents were still minors, and that the nationality of their parents as entered in their respective Certificates of Live Birth remained “Chinese.”

• No Error to Correct / Citizenship Determined at Birth: Petitioner Republic maintained that there was no error to correct in the respondents’ Certificates of Live Birth because citizenship is determined at the time of one’s birth; on the day Winston Brian, Christopher Troy, and Jon Nicholas were born, their parents were still Chinese nationals, so the respondents were natural-born Chinese and the nationality of their parents was correctly entered as “Chinese.”
• Need for Special Committee on Naturalization Proceeding: Petitioner Republic argued that even assuming the nationality of the respondents’ parents as entered in the Certificates of Live Birth may be changed, the change can be done only after an appropriate proceeding under the Implementing Rules and Regulations of Presidential Decree No. 836, in relation to Presidential Decree No. 923, before the Special Committee on Naturalization to determine if the respondents are qualified to become naturalized Filipinos.

• Rule 108 Appropriate: Respondents Winston Brian, Christopher Troy, and Jon Nicholas contended that the Manila and Quezon City trial courts committed no reversible error since they had jurisdiction to change a substantial entry in the Certificates of Live Birth—their parents’ nationality—pursuant to Rule 108 of the Rules of Court.
• Applicability of Co vs. The Civil Register of Manila: Respondents argued that Co vs. The Civil Register of Manila allowed the change in the nationality of parents as entered in a certificate of live birth, and that the case is applicable because their father was naturalized under Letter of Instructions No. 270, the same law under which the father in Co applied for naturalization.
• Automatic Derivative Citizenship: Respondents maintained that Letter of Instructions No. 270 is in pari materia with Section 15 of Commonwealth Act No. 473, which automatically granted Philippine citizenship to the minor children of the naturalized Filipino under certain conditions; they established that their father was naturalized under Letter of Instructions No. 270, that they were born in the Philippines, and that they were minors at the time their father was granted Philippine citizenship, so they should likewise be deemed Filipinos.
• Irrelevance of Prior SCN Proceeding / Estoppel: Respondents argued that they never disputed the Special Committee on Naturalization’s jurisdiction over administrative proceedings for acquiring Philippine citizenship, but that the issue of whether a proceeding should first be conducted is irrelevant; Jon Nicholas specifically maintained that the Special Committee on Naturalization is estopped from claiming that a proceeding should first be conducted since it actively participated as a witness before the trial court.

• Change of Parents’ Nationality in Birth Certificates: Whether the nationality of the parents of Winston Brian, Christopher Troy, and Jon Nicholas Chia Lao, as entered in their respective Certificates of Live Birth, may be changed to “Filipino” considering that, at the time of their birth, their parents were still Chinese nationals.
• Need for Special Committee on Naturalization Proceeding: Whether an appropriate proceeding before the Special Committee on Naturalization to determine whether an individual is qualified to acquire Filipino citizenship is required before the nationality of a person’s parents, as entered in the birth certificate, may be changed.

• Change of Parents’ Nationality in Birth Certificates: Yes. The nationality of the parents as entered in the respondents’ Certificates of Live Birth may be changed to “Filipino” under Rule 108 of the Rules of Court, because the parents’ subsequent naturalization is an act or event affecting civil status that may be recorded in the civil register, and the trial courts complied with the requirements of Rule 108.
• Need for Special Committee on Naturalization Proceeding: No. A prior proceeding before the Special Committee on Naturalization is not required for the minor children, who follow the acquired Filipino citizenship of their mother under Presidential Decree No. 836, as amended by Presidential Decree No. 923; only the naturalized person and his wife undergo the proceeding before the Special Committee on Naturalization.

• Change of Parents’ Nationality in Birth Certificates: The Civil Code requires acts, events, and judicial decrees concerning civil status to be recorded in the civil register, and Article 412 prohibits any change or correction in the civil register without a judicial order. The word “changed” in Article 412 contemplates events occurring after birth. Article 408 includes naturalization and loss or recovery of citizenship among registrable matters. In Co vs. The Civil Register of Manila, the Court allowed the correction of the parents’ nationality in birth certificates under Rule 108 where the father had been naturalized after the children’s birth. The Court there held that Letter of Instructions No. 270 and Commonwealth Act No. 473 are in pari materia, so Section 15 of Commonwealth Act No. 473—granting Philippine citizenship to minor children of naturalized persons—was read into Letter of Instructions No. 270. Here, the respondents alleged and proved the ultimate facts: they are legitimate children of Lao Kian Ben and Chia Kong Liong; their parents are naturalized Filipino citizens; and their Certificates of Live Birth still show their parents’ nationality as “Chinese.” Because the entry sought to be changed—citizenship—was substantial, the trial courts correctly conducted adversarial proceedings under Rule 108, with notice and publication, and correctly ordered that the decisions be annotated in the Certificates of Live Birth. The Court also emphasized that the birth certificate is an instrument of individuation, and refusing to annotate subsequent events would deny a person the right to form his or her identity.
• Need for Special Committee on Naturalization Proceeding: Naturalization may be administrative, judicial, or legislative. Lao Kian Ben applied under Letter of Instructions No. 270 and was granted citizenship under Presidential Decree No. 923, which provided the same effects and conditions as Presidential Decree No. 836. Under Presidential Decree No. 836, alien wives and minor children of persons naturalized under the Decree are deemed Philippine citizens, provided the wife does not suffer from any disqualification under Letter of Instructions No. 270 and the wife and minor children reside permanently in the Philippines at the time of naturalization. The only persons required to undergo the proceeding before the Special Committee on Naturalization are the naturalized person and his wife; the minor children “follow the acquired Filipino citizenship of their mother.” The entries sought to be changed are the parents’ nationalities in the respondents’ birth certificates, so the relevant issue is whether Lao Kian Ben and Chia Kong Liong were issued Certificates of Naturalization and took their Oaths of Allegiance, which they did. Thus, no prior proceeding before the Special Committee on Naturalization was required for the respondents.

• Rule 108 of the Rules of Court as the procedure for substantial corrections in the civil register — Article 412 of the Civil Code prohibits any change or correction in the civil register without judicial order, and Rule 108 supplies the procedure. It covers not only clerical errors but also substantial entries such as nationality or citizenship. When the entry sought to be changed is substantial, the proceeding must be adversarial, with notice to the local civil registrar and interested parties and publication. In this case, the trial courts correctly used Rule 108 to allow the change of the parents’ nationality in the respondents’ Certificates of Live Birth.
• Annotation of post-birth events in the certificate of live birth — Although entries in the birth certificate generally correspond to facts at birth, Articles 407 and 412 of the Civil Code permit acts or events occurring after birth to be recorded in the civil register. The birth certificate is not merely a historical record; it is a vital marker of identity and an instrument of individuation. Thus, the parents’ subsequent naturalization may be annotated on the children’s Certificates of Live Birth so that the recorded nationality aligns with the legal truth.
• Pari materia treatment of Letter of Instructions No. 270 and Commonwealth Act No. 473 — Following Co vs. The Civil Register of Manila, Letter of Instructions No. 270 and Commonwealth Act No. 473 are statutes in pari materia. Absent express repeal, Section 15 of Commonwealth Act No. 473—which extends Philippine citizenship to the minor children of naturalized persons—is read into Letter of Instructions No. 270. The minor children of persons naturalized under Letter of Instructions No. 270 therefore acquire Philippine citizenship under the same terms.
• Automatic derivative citizenship of minor children; no separate SCN proceeding — Under Presidential Decree No. 836, as amended by Presidential Decree No. 923, the alien wife and minor children of a naturalized person are deemed Philippine citizens, subject to the wife’s qualifications and the family’s residence in the Philippines. Only the naturalized person and his wife undergo the proceeding before the Special Committee on Naturalization; the minor children follow the acquired Filipino citizenship of their mother. Consequently, the minor children need not first undergo a separate naturalization proceeding before the Special Committee on Naturalization to have their parents’ nationality corrected in their birth certificates.
• Modes of naturalization — Naturalization may be administrative, judicial, or legislative. Administrative naturalization is governed by Republic Act No. 9139; judicial naturalization is governed by the Revised Naturalization Law; and legislative naturalization is bestowed through a statute enacted by Congress. This classification frames the Court’s analysis that the father’s naturalization under Letter of Instructions No. 270 and Presidential Decree No. 923 was a special statutory grant with derivative effects on his wife and minor children.

• “The birth certificate, more than a historical record of one’s birth, is a vital marker of identity. Therefore, acts and events, though occurring after birth, may be annotated on the birth certificate so long as they are consistent with a legal truth and a special law provides for its effects.” — This opening passage states the core rationale for allowing post-birth events, such as a parent’s naturalization, to be annotated on the birth certificate.
• “Absent any express repeal of Section 15 of [Commonwealth Act] No. 473 [on the effect of the naturalization on wife and children] in [Letter of Instruction] No. 270, the said provision should be read in to the latter law as an integral part thereof, not being inconsistent with its purpose.” — Quoted from Co vs. The Civil Register of Manila, this passage supplies the basis for treating Letter of Instructions No. 270 and Commonwealth Act No. 473 as statutes in pari materia and for extending derivative citizenship to minor children.
• “Clear from Presidential Decree Nos. 836 and 923 is that the naturalization extends to the alien wife and minor children of the person naturalized upon the wife’s showing that she does not suffer from any of the disqualifications under Letter of Instructions No. 270, and that she and her minor children reside permanently in the Philippines at the time of her husband’s naturalization. In other words, the only persons to undergo the proceeding before the Special Committee on Naturalization will only be the person naturalized and his wife. The minor children, in the words of Letter of Presidential Decree No. 836 “follow the acquired Filipino citizenship of their mother.”” — This passage is the Court’s ratio for holding that the respondents, as minor children, did not need to undergo a separate proceeding before the Special Committee on Naturalization.
• “To prohibit the annotation of events subsequent to birth in the certificate of live birth is to deny a person the right to form his or her own identity. More than a “historical record of the facts as they existed at the time of birth,” the birth certificate is an instrument of individuation. It contains entries that separates a person from others.” — This passage articulates the policy foundation for treating the birth certificate as an instrument of identity and for permitting the annotation of subsequent legal events.

• Co vs. The Civil Register of Manila, 467 Phil. 904 (2004) — Controlling precedent. The Court relied on it in allowing the change in the nationality of parents as entered in a certificate of live birth under Rule 108, and in holding that Letter of Instructions No. 270 and Commonwealth Act No. 473 are in pari materia, with Section 15 of Commonwealth Act No. 473 applying to the minor children of those naturalized under Letter of Instructions No. 270.
• Silverio vs. Republic, 562 Phil. 953 (2007) — Cited for the proposition that a birth certificate is more than a historical record of the facts as they existed at the time of birth; it is an instrument of individuation.
• Republic vs. Unabia, G.R. No. 213346, February 11, 2019 — Cited through Justice Leonen’s Concurring Opinion for the principle that the birth certificate is an instrument of individuation.
• So vs. Republic, 542 Phil. 259 (2007) — Cited for the classification of naturalization into administrative, judicial, and legislative modes.

• Article 407, Civil Code — Provides that acts, events, and judicial decrees concerning the civil status of persons shall be recorded in the civil register. Applied to allow the parents’ subsequent naturalization to be recorded in the respondents’ Certificates of Live Birth.
• Article 408, Civil Code — Enumerates the matters to be entered in the civil register, including births, naturalization, and loss or recovery of citizenship. Applied to establish that citizenship and naturalization are registrable matters.
• Article 412, Civil Code — Prohibits any change or correction in a civil register without a judicial order. The Court read the word “changed” as contemplating events occurring after birth, thereby supporting the annotation of the parents’ naturalization.
• Section 5, Act No. 3753 — Requires the certificate of live birth to include the names, citizenship, and religion of the parents. Applied to recognize that the parents’ citizenship is a required entry in the birth certificate.
• Rule 108, Rules of Court — Provides the procedure for cancellation or correction of entries in the civil registry. Applied as the proper remedy for changing a substantial entry such as nationality, with notice, publication, and adversarial proceedings.
• Section 15, Commonwealth Act No. 473 — Provides the effect of naturalization on the wife and children, including that minor children of persons naturalized under the law who were born in the Philippines shall be considered citizens. Read into Letter of Instructions No. 270 by reason of pari materia treatment.
• Letter of Instructions No. 270 — Established the Special Committee on Naturalization and the qualifications and disqualifications for naturalization by decree. Applied as the law under which Lao Kian Ben applied for naturalization.
• Presidential Decree No. 836 — Grants Philippine citizenship to deserving aliens and provides that alien wives and minor children of persons naturalized under the Decree shall be deemed Philippine citizens, subject to conditions. Applied to hold that minor children follow the acquired Filipino citizenship of their mother and need not undergo a separate SCN proceeding.
• Presidential Decree No. 923 — Grants Philippine citizenship to a second group of applicants and provides the same effects and conditions as Presidential Decree No. 836. Applied as the decree under which Lao Kian Ben and Chia Kong Liong were naturalized.
