Antonio Chieng v. Spouses Eulogio

Summary

This case arose from a P200,000 loan secured by real estate mortgage, where the borrower issued bounced checks leading to criminal prosecution under BP 22. The Supreme Court addressed whether filing criminal cases for bounced checks bars subsequent foreclosure of the mortgage securing the same debt. While acknowledging that the criminal prosecution impliedly included a civil collection action that would normally preclude foreclosure under the alternative remedies rule, the Court applied the principle of unjust enrichment to prevent the borrowers from benefiting without full payment. The decision clarified the interaction between criminal prosecution for bounced checks and civil mortgage remedies, ultimately allowing recovery of the unpaid loan balance through unjust enrichment doctrine rather than foreclosure. The Court corrected the interest computation and ordered payment of the remaining P93,000 balance plus legal interest, demonstrating the Court's equity jurisdiction in preventing unjust enrichment while respecting procedural rules.
