The impeachment trial of Philippine Vice President Sara Duterte officially commenced in Manila this past Monday, drawing significant attention as the Senate began the process of establishing its judicial framework. With 21 senators in attendance, the chamber elected Senator Francis Escudero to preside over the proceedings after a brief debate. In his opening address, Escudero clarified the rigorous requirements for conviction, noting that under the 1987 Constitution, a two-thirds majority—or 16 votes—is necessary to remove the Vice President from office. He also emphasized a flexible approach to evidence, stating that the court would prioritize a “clear and convincing” standard over the traditional criminal benchmark of proof beyond a reasonable doubt.

The opening day highlighted the starkly different strategies of the two legal teams. Chief Prosecutor Gerville Luistro framed the case as a matter of constitutional accountability, pledging to present concrete financial documents and official records rather than hearsay. Conversely, the defense, led by lawyer Sheila Sison, argued that the proceedings are a political attack that undermines the will of the 32 million voters who elected Duterte. Sison further countered by questioning the integrity of the House prosecutors themselves. As the trial moves forward, observers anticipate a high-stakes legal battle that will test the country’s institutions, with the proceedings scheduled to continue for at least 92 days.
