Supreme Court upheld BP 22's constitutionality, ruling it punishes issuing worthless checks, not debt non-payment, as a valid exercise of police power to protect public welfare.

Case Summary (G.R. No. L-63419)

Historical Antecedents in Estafa Law

Under Spanish and early Philippine law, issuance of worthless checks was prosecuted as estafa (fraud). An amendment in 1926 explicitly covered checks but omitted those issued for pre-existing debts. Article 315 of the 1932 Revised Penal Code continued this limitation. Republic Act No. 4885 (1967) tried to close the gap by treating failure to cover a dishonored postdated check within three days as prima facie deceit, but courts still held that checks issued for pre-existing debts fell outside estafa’s scope.

Legislative Evolution and Rationale for BP 22

Recognizing that most dishonored checks paid pre-existing debts, the Interim Batasan enacted BP 22 in 1979 to address the “bouncing check” problem directly, treating issuance of a worthless check as malum prohibitum under the state’s police power. Reported daily volume of such checks reached tens of millions of pesos, threatening public confidence in the banking system and impairing commerce.

Interlocutory Appeal and Jurisdiction

Although orders denying motions to quash informations are interlocutory, the Court exercised its discretion to entertain these petitions on the constitutional challenge given the statute’s public importance and the resulting uncertainty in judicial and commercial circles.

Constitutional Challenge: Imprisonment for Debt

Petitioners argued BP 22 effectively punishes non-payment of debt, contravening the constitutional prohibition (“No person shall be imprisoned for debt …”). The Court differentiated between punishing non-payment of obligations (ex contractu) and prohibiting issuance of worthless checks as an offense against public order. Drawing on Philippine and U.S. precedents, it held that laws enacted under police power to outlaw malum prohibitum acts—unrelated to pure debt enforcement—do not violate the debt-imprisonment ban.

Police Power and Public Welfare

The Court affirmed that the state’s inherent police power permits penalizing acts harmful to public welfare, even if they are not malum in se. Issuing worthless checks undermines confidence in demand-deposit banking, which comprised one-third of the money supply, and thus justifies criminal sanctions to protect commerce and public interest.

Other Constitutional Objections

• Freedom of Contract: Protected only for lawful contracts; checks are regulated commercial instruments, not pure private contracts.
• Equal Protectio
