Anthony Sy, Sr. v. The Honorable Intermediate Appellate Court (4Th Special Cases Division)

Summary

This consolidated case involved a P50 million land dispute in Muntinlupa, Metro Manila, with overlapping titles between multiple parties. The primary legal issue was whether formal written notice of counsel's change of address was required when the trial court had actual knowledge of the change. Counsel Nemesio Diaz had been using his new address in pleadings and the court had been sending orders to the new address, but the crucial decisions were sent to his old address and returned unserved. The Supreme Court distinguished the case from Philippine Suburban Development Corporation, holding that when a court has actual knowledge of counsel's address change and has been acting on it, service to the old address does not start the appeal period. The Court granted relief to one petitioner while denying the other, emphasizing that while formal notice is preferred, compelling equitable circumstances may overcome strict rule observance.
