Can the Sara Duterte Impeachment Still Persuade Those Entrusted to Decide?
One of the oldest principles in democratic justice is that courts do not exist merely to decide cases. They exist to inspire confidence that cases are decided fairly. This is the essence of the familiar legal maxim that justice must not only be done but must also be seen to be done. The legitimacy of any judicial or quasi-judicial proceeding ultimately depends not only on the correctness of its verdict but also on whether reasonable people believe the process remained open to persuasion until the very end.
That principle is now being tested in the impeachment trial of Vice President Sara Duterte.
On paper, the proceedings possess every hallmark of constitutional due process. The prosecution presents documentary evidence and witnesses. The defense challenges admissibility, disputes credibility, and raises constitutional objections. Senator-judges ask questions, rule on motions, and receive evidence. The proceedings unfold according to established rules rather than political speeches. From a procedural standpoint, the impeachment resembles precisely what the Constitution envisioned.
Yet outside the Senate chamber, another reality has emerged. The public conversation remains dominated not by evidence but by numbers. Political observers continue to count presumed votes instead of examining testimony. Every witness is immediately interpreted according to whether the prosecution or the defense “won the day.” Every procedural ruling is analyzed for its political implications. The question that repeatedly surfaces is no longer whether the evidence will persuade the Senate but whether the Senate is still capable of being persuaded.
That distinction is more important than it first appears.
Every trial has two audiences. The first consists of those constitutionally tasked to decide the case. The second is the public whose confidence ultimately gives the institution its legitimacy. The prosecution’s responsibility is to persuade the court. The defense’s responsibility is to create reasonable doubt about the prosecution’s claims. Those are expected roles in every adversarial proceeding. The Senate’s responsibility, however, is fundamentally different. It must persuade the public that the evidence still matters and that the proceedings remain capable of influencing the judgment of those who will ultimately vote.
This is where the impeachment faces its greatest institutional challenge.
No one can know what is inside the mind of any senator. Nor should anyone casually assume that votes have already been decided before the proceedings conclude. Such assumptions would be unfair to the institution and impossible to prove. What cannot be ignored, however, is the growing public perception that political alignments may matter more than evidence itself. Whether justified or not, that perception carries consequences because constitutional institutions derive much of their authority from public trust. If citizens conclude that no amount of evidence can alter the eventual outcome, then every witness risks becoming symbolic, every objection performative, and every legal argument little more than an exercise in validating conclusions reached elsewhere.
The danger, therefore, is not necessarily that justice is absent. The greater danger is that too many people begin to believe that justice has become predictable. Democracies can survive acquittals and convictions. They struggle to survive when citizens lose confidence that constitutional processes remain capable of changing minds. Once that confidence disappears, impeachment ceases to function as an instrument of accountability and begins to resemble political theatre whose ending is assumed before the opening act has concluded.
This is why the burden on the Senate extends beyond rendering a legally defensible verdict. The chamber must demonstrate through its conduct that every senator remains genuinely open to persuasion by the evidence presented. That obligation cannot be fulfilled through speeches declaring impartiality or through repeated assurances of independence. Institutional credibility is earned procedurally. It is reflected in the seriousness with which witnesses are examined, in the fairness of evidentiary rulings, in the consistency of legal reasoning, and ultimately in the public’s belief that constitutional duty prevailed over political convenience.
Ironically, the prosecution and the defense are expected to perform. They are advocates. Their task is to persuade, to challenge, to object, and to advance their respective cases as vigorously as possible. The Senate, however, performs a different role altogether. Its performance is not advocacy but impartiality. The institution succeeds only if Filipinos believe that its members approached the proceedings not as political allies or political adversaries but as constitutional judges willing to follow the evidence wherever it leads.
Whether the impeachment ultimately ends in conviction or acquittal is unquestionably important. Yet history may ask an even larger question. It may ask whether the proceedings strengthened public confidence in one of the Republic’s gravest constitutional processes or reinforced the growing belief that political outcomes are settled before constitutional rituals begin.
That is the real audience before which the Senate now appears.
The impeachment may determine the political future of Vice President Sara Duterte. The conduct of the trial will determine something equally enduring: whether Filipinos continue to believe that constitutional institutions still possess the capacity to persuade those entrusted to judge before they render judgment.
