Co Kim Cham vs. Tan Keh
Case
G.R. No. L-5a
Decision Date
Nov 16, 1945
A motion for reconsideration sought to validate judicial acts during Japan's WWII occupation of the Philippines, contested under MacArthur's proclamation. The Supreme Court upheld the validity of occupation-era judicial processes, ruling they were essential for public order and not nullified by the proclamation.

Case Summary (G.R. No. L-5a)

Continuation of Municipal Laws and Courts under Hague Conventions

Even under belligerent occupation, the Hague Conventions impose a duty on the occupant to maintain existing municipal laws and courts “for the protection and benefit of the inhabitants,” ensuring public order and safety. Failure to maintain them would unduly disrupt civil life. Hence, judicial acts of courts operating under occupation remain valid unless expressly suspended by the occupant.

Renunciation of War and Protection of Judicial Acts

The Kellogg–Briand Pact and constitutional renunciation of war do not invalidate the Hague Convention rules permitting an occupant to preserve local judiciary. Upholding occupation-era judicial acts serves the rights of inhabitants and prevents rewarding the aggressor or further harming the conquered population.

Scope of “Processes” in MacArthur’s Proclamation

General MacArthur’s October 23, 1944 proclamation nullified “all laws, regulations and processes” of any government other than the Commonwealth. The Court applied the interpretive maxim noscitur a sociis, holding that “processes” refers to legislative and constitutional instruments (e.g., executive orders, ordinances, constitutions) and not to judicial process—service of process or court proceedings—so as to allow occupation‐era courts to continue civil actions involving private rights.

Indefeasibility of Occupation-Era Judgments under Law of Nations

Judicial acts under occupation—applying pre-occupation municipal law to private rights—are valid before and after the lapse of occupation. Their reversal by the restored government would inflict national wrong on vested rights, even if no “international wrong” might be shown. Precedent from U.S. Supreme Court cases (e.g., Dow v. Johnson; Raymond v. Thomas) confirms that military or occupation authorities may not arbitrarily abrogate judicial decisions affecting private rights.

Status of Occupation-Era Courts Relative to Japanese Courts

Courts maintained under occupation function as local tribunals under military authority but are not foreign (Japanese) courts. Analogous to U.S. military courts in conquered territory (e.g., Jecker v. Montgomery), they serve public order and protect inhabitants; their decisions are not Japanese judicial acts and thus are inheritable by the restored Commonwealth judiciary.
