G.R. No. L-61355 February 18, 1983
MAXIMO G. RODRIGUEZ, petitioner, vs. THE HON. SANDIGANBAYAN, Second Division, THE PEOPLE OF THE PHILIPPINES, herein represented by the HON. TANOD-BAYAN and ATTY. DIGNO A. ROA, respondents.

FACTS

Petitioner Maximo G. Rodriguez, former Provincial Fiscal and Ex-Officio Register of Deeds of Misamis Oriental, was charged before the Sandiganbayan for violation of the Anti-Graft and Corrupt Practices Act. The charges originated from a 1977 complaint. After a series of preliminary investigations by different prosecutorial bodies, including the City Fiscal and the newly created Tanodbayan, a team of special prosecutors was directed to conduct a new investigation focused on the graft charge. A subpoena for this investigation, scheduled from October 19-25, 1980 in Cagayan de Oro, was served on petitioner’s wife in his absence. Petitioner was then in Catarman attending to his sick mother and subsequently traveled to Manila for a court appearance. He was unaware of the ongoing proceedings. Although his law partner and son appeared and participated in the investigation, petitioner denied authorizing them. Upon returning to Cagayan de Oro on October 23, he found the investigators had already departed. He later went to Manila to file a memorandum.

ISSUE

Whether the Sandiganbayan acquired jurisdiction over the criminal case despite alleged defects in the preliminary investigation, particularly the denial of petitioner’s right to due process.

RULING

The Supreme Court granted the petition, annulling the Sandiganbayan proceedings and directing a proper preliminary investigation. The legal logic centers on the violation of procedural due process, which is fundamental to jurisdiction. The Court held that while a preliminary investigation is not a trial and is not essential for the court’s jurisdiction over the offense, a denial of due process during that stage can invalidate subsequent proceedings if it prejudices the accused’s rights. Here, petitioner was effectively deprived of his right to be heard. The subpoena was not personally served, and he had no knowledge of the scheduled dates. The participation of his law partner and son was unauthorized and could not substitute for his own, as they were not privy to the specific facts known only to him. The investigating body’s failure to wait for him until the last scheduled day, despite his appearance on October 23, deprived him of the opportunity to cross-examine witnesses and present his defense adequately. This impairment was not cured by his subsequent filing of a memorandum. Furthermore, the Court noted the practical inequity of compelling him to stand trial in Manila, incurring significant expenses pitted against the government’s resources, which contravenes the “sporting idea of fair play” inherent in due process. Consequently, the flawed preliminary investigation rendered the Information filed with the Sandiganbayan invalid, and the court did not acquire proper jurisdiction.
