Aglipay v Ruiz 64 PHIL 201 (1937)

Facts: Petitioner seeks the issuance of a writ of prohibition against respondent Director of Posts from issuing and selling postage stamps commemorative of the 33rd International Eucharistic Congress. Petitioner contends that such act is a violation of the Constitutional provision stating that no public funds shall be appropriated or used in the benefit of any church, system of religion, etc. This provision is a result of the principle of the separation of church and state, for the purpose of avoiding the occasion wherein the state will use the church, or vice versa, as a weapon to further their ends and aims. Respondent contends that such issuance is in accordance to Act No. 4052, providing for the appropriation funds to respondent for the production and issuance of postage stamps as would be advantageous to the government.
