Academic Analysis of Rule 18 Sub Judice Rule Abandonment

The selective abandonment of Rule 18’s sub judice restriction—effectuated as the concomitant of the prosecution’s unilateral withdrawal of Articles I, III, and IV—compromises the structural integrity of due process and the conditions of fairness that the rule is designed to secure for the defense in an ongoing impeachment trial.
In the Senate impeachment court proceedings against Vice President Sara Duterte (as of 13 October 2026), Rule 18 of the Rules of Procedure on Impeachment Trials prohibits the presiding officer, senator-judges, prosecutors, the respondent, counsel, and witnesses from making public comments or disclosures concerning the merits of matters pending adjudication. Its purpose is classically prophylactic: to avert trial by media, to insulate the tribunal from extrajudicial pressure or contamination of the evidentiary field, and thereby to preserve both the appearance and the reality of impartial adjudication. The rule is not merely procedural housekeeping; it is an institutional embodiment of the fair-trial guarantee that forms part of due process under the Philippine constitutional order and the broader common-law tradition of contempt-by-publication doctrine.
When the House prosecution panel was permitted to withdraw Articles I (alleged misuse of confidential funds), III (bribery), and IV (grave threats), the court simultaneously declared that the *sub judice* bar no longer applied to those discrete articles. Presiding Officer Escudero reasoned that, the charges having ceased to be pending for adjudication or vote, the parties—particularly the respondent—should be free to answer them in the public square, lest she be “shackled” by silence both inside and outside the courtroom. The restriction remained intact solely with respect to the surviving Article II (unexplained wealth). The defense, through lead counsel Sheila Sison, objected that this midstream abandonment of Rule 18, occurring precisely as the respondent prepared to present her case, undermines the integrity of the proceedings as a whole.
The objection is analytically sound for several interlocking reasons.
First, temporal and sequential asymmetry. The sub judice rule is not a set of free-standing silos corresponding to individual articles; it is a systemic discipline that governs the entire adjudicative environment while any charge remains pending. By lifting the restriction on three articles after the prosecution has already adduced evidence on at least two of them, the court creates a temporal window in which the prosecution (and aligned public voices) may re-litigate, re-characterize, or amplify the withdrawn allegations outside the controlled evidentiary rules of the court, while the defense is still bound by Rule 18 with respect to the residual charge and is simultaneously preparing its affirmative case. The result is a one-sided public narrative that can shape the informational and psychological context in which the remaining charge will be decided. Due process requires not merely formal opportunity to be heard on the charges that survive, but a fair opportunity to be heard in an environment that has not been pre-contaminated by unregulated commentary on closely related (and previously litigated) allegations.
Second, the fiction of clean severance. Although the court insists that the withdrawn articles are no longer “pending for adjudication,” the evidentiary material already received on Articles I and IV remains part of the formal record. The ruling carefully preserves confidentiality and protective-order constraints on that material, yet simultaneously licenses public discussion of “any matter contained in those withdrawn Articles.” In practice, the boundary between discussing the allegations and discussing (or selectively recalling) the evidence already presented is porous. The defense is thereby placed in the position of having to respond, in the media arena, to a partially developed evidentiary narrative without the reciprocal protections of cross-examination, contemporaneous objection, or the formal rules of evidence that would apply inside the courtroom. This is the classic “trial by media” hazard that the sub judice principle exists to prevent.
Third, strategic unilateralism and the equality of arms. The decision to withdraw was the prosecution’s; the defense did not seek it. Yet the procedural consequence—release from the sub judice constraint—operates upon both parties while the defense is still preparing its case. The equality-of-arms principle, a core component of fair-trial jurisprudence, is strained when one side can elect to narrow the formal charges and, by that same election, open a parallel public forum in which residual narrative advantages can be exploited. The respondent is told she may now “defend her reputation” publicly with respect to the dropped articles; yet she remains under the Rule 18 muzzle with respect to the sole surviving article, and any public engagement with the withdrawn charges risks spillover effects that could be construed as commenting on the merits of the remaining charge or as generating prejudicial publicity that the tribunal itself has authorized.
Fourth, systemic integrity versus discrete charge management. The *sub judice* rule’s rationale, as articulated in both domestic Philippine doctrine and comparative common-law sources, is not limited to preventing prejudice to the specific charge under deliberation; it is to maintain the dignity and impartiality of the judicial (or quasi-judicial) process as such. Selective mid-trial abandonment converts a structural safeguard into a contingent managerial tool. Once the court signals that the rule may be relaxed when charges are withdrawn, the incentive structure shifts: a prosecutor may litigate aggressively on multiple fronts, develop a public narrative, then withdraw the weaker or more politically costly counts and thereby unlock public commentary that continues to color the residual proceeding. The defense, by contrast, cannot unilaterally expand or contract the field in the same way. The result is a procedural asymmetry that is difficult to reconcile with the demand that the tribunal remain a neutral and insulated decision-maker until final judgment.
In sum, the court’s solution—framed as a liberalizing measure intended to free the respondent from a double bind of silence—achieves formal symmetry at the price of substantive fairness. By treating the *sub judice* constraint as severable charge-by-charge rather than as an environmental condition of the entire trial, and by doing so at the precise moment the defense is about to enter the field, the ruling undermines the very protective architecture that due process and the fair-trial principle require. The integrity of the remaining adjudication cannot be insulated from the public discourse the court has now authorized; the two spheres are porous, and the defense is left to navigate both under unequal constraints. That is the deeper institutional cost of the trade-off.
Conclusion
The selective abandonment of Rule 18’s *sub judice* restriction, timed with the prosecution’s withdrawal of three articles, fundamentally compromises the structural safeguards of due process and fair trial rights in the impeachment proceedings. By treating the rule as severable rather than systemic, the court opens a parallel public forum in which previously litigated allegations may continue to shape the informational environment surrounding the sole remaining charge. This midstream relaxation, occurring precisely as the defense prepares its case, generates temporal asymmetry and undermines the equality of arms. The formal justification—that withdrawn articles are no longer pending—fails to account for the residual evidentiary record and the porous boundary between authorized commentary and prejudicial spillover. In elevating managerial convenience over institutional integrity, the ruling converts a prophylactic guarantee into a contingent privilege. Due process demands more than formal opportunity to respond; it requires an uncontaminated adjudicative space. The trade-off therefore exacts a lasting cost: it erodes confidence that the residual proceedings will be decided solely on the evidence and arguments properly before the tribunal, free from the distorting effects of unregulated public narrative.

----
A multidisciplinary Filipino artist, poet, researcher, and cultural worker whose practice spans painting, printmaking, photography, installation, and writing. He is deeply rooted in cultural memory, postcolonial critique, and in bridging creative practice with scholarly infrastructure—building counter-archives, annotating speculative poetry like Southeast Asian manuscripts, and fostering regional solidarity through ethical art collaboration.
He has been active in the Philippine art scene since the late 1990s and has worked with galleries, museums, artist-run spaces, and international cultural organizations.His practice appears to represent several interconnected concerns:
Cultural work as artistic practice. Roldan has argued that the labor of curating, organizing exhibitions, teaching, documentation, and cultural administration should be understood as creative work rather than merely support work. This perspective has been reflected in his writings and exhibitions.
Social and political engagement. His artworks frequently address politics, religion, faith, denial, courage, social inequality, and the everyday experiences of Filipinos. He has stated that he draws inspiration from Filipino cultural practices while approaching painting, printmaking, and installation from a conceptual perspective.Printmaking and conceptual art. Roldan is particularly recognized for his printmaking, with works shown internationally, including exhibitions in Japan and France. His practice also encompasses painting, photography, installation, and curatorial research.International cultural exchange. A significant milestone in his career was receiving an Asian Cultural Council fellowship in 2003, which enabled him to undertake research and create work in the United States while engaging with artists and curators internationally.
More broadly, Roldan's work represents an attempt to bridge artistic production, curatorial practice, scholarship, and cultural activism . His writings often emphasize postcolonial discourse, cultural memory, and the ethics of artistic collaboration, positioning the artist not only as a maker of objects but also as a builder of cultural infrastructure.
In the Philippine contemporary art context, he can be understood as representing the figure of the artist-curator-cultural worker —someone who contributes both through making artworks and through developing exhibitions, mentoring artists, and fostering institutional and independent cultural initiatives.
