Leung Ben v. O'Brien

Summary

Leung Ben sought certiorari to quash an attachment issued against his bank deposit in a case where P.J. O'Brien sued to recover P15,000 allegedly lost in gambling games. The Supreme Court En Banc addressed two key issues: whether it had jurisdiction to review attachment orders via certiorari, and whether gambling debt recovery constitutes a 'contract, express or implied' for attachment purposes. The Court held it had jurisdiction to review when lower courts exceed authority in granting attachments, as attachment jurisdiction is separate from main action jurisdiction. More significantly, the Court conducted extensive analysis of common law and civil law contract principles, concluding that the statutory obligation under Act No. 1757 to restore gambling winnings creates a duty imposed by law (ex lege) that constitutes an implied contract or quasi-contract. The petition was denied, upholding the attachment. This case established important precedent on Supreme Court's certiorari jurisdiction over attachment orders and the contractual nature of statutory gambling debt recovery obligations.
