Case Digest (G.R. No. L-21289)
Expanded Legal Reasoning Model

Facts:

  • Procedural Background
    • Petitioners Moy Ya Lim Yao (alias Edilberto Aguinaldo Lim) and Lau Yuen Yeung sought a writ of injunction restraining the Commissioner of Immigration from ordering Lau’s departure, arrest, deportation, and bond forfeiture.
    • The trial court denied their plea for preliminary injunction, heard the case on the merits (Civil Case No. 49705, CFI Manila), and afterward dismissed the complaint.
  • Immigration and Marital History of Lau Yuen Yeung
    • February 8, 1961 – Lau applied for a one-month non-immigrant visitor’s visa to the Philippines, stating she was a Chinese national residing in Kowloon, Hong Kong, coming to visit her great-grand-uncle.
    • March 13, 1961 – Admitted and posted a ₱1,000 bond guaranteeing departure; received extensions of stay until February 13, 1962.
    • January 25, 1962 – Married Moy Ya Lim Yao, a Filipino citizen.
    • Government threatened deportation and bond forfeiture for “overstaying” after February 13, 1962.
  • Trial Court Findings and Government’s Position
    • Lau could not read/write English or Tagalog, had limited social integration with Filipinos, and lacked the ten-year residence otherwise required for naturalization.
    • Solicitor General’s objections:
      • Under Immigration Act Sec. 9(g), a non-immigrant alien may not convert temporary stay into permanent residence without first departing and obtaining a new visa.
      • Revised Naturalization Law Sec. 15 (“Effect of Naturalization on Wife and Children”) requires the alien wife to “possess all the qualifications and none of the disqualifications” for naturalization in order to be deemed a citizen.
    • On these bases, the trial court held Lau did not become a Filipino by marriage and denied injunctive relief.

Issues:

  • Whether Immigration Act Sec. 9(g) bars Lau Yuen Yeung from permanent stay despite her claim to Filipino citizenship by marriage.
  • Whether Revised Naturalization Law Sec. 15 requires both statutory qualifications and absence of disqualifications for an alien woman to become a Filipino citizen upon marrying a Filipino.
  • Whether the trial court erred in dismissing the complaint and refusing to enjoin the Commissioner of Immigration.
