Case
A.M. No. 18-06-01-SC
Decision Date
Jul 17, 2018
Former Chief Justice Sereno reprimanded for violating sub judice rule through public statements during quo warranto proceedings, undermining judicial integrity.

Case Summary (A.M. No. 18-06-01-SC)

Petitioner

Republic of the Philippines, represented by Solicitor General Jose C. Calida.

Respondent

Maria Lourdes P. A. Sereno, former Chief Justice of the Supreme Court.

Key Dates

• August 30, 2017 – Impeachment complaint filed in the House of Representatives.
• May 11, 2018 – Decision ordering Sereno to show cause for alleged violations of the sub judice rule and professional standards.
• March 25, 2019 – En Banc decision on the administrative matter.

Applicable Law

• 1987 Philippine Constitution
• Code of Professional Responsibility (CPR)
• New Code of Judicial Conduct for the Philippine Judiciary (NCJC)
• Rule 71, Section 3 of the Rules of Court (indirect contempt provisions)

Factual and Procedural Antecedents

Sereno faced simultaneous impeachment and quo warranto proceedings in 2017–2018. While the impeachment complaint alleged constitutional violations and corruption, the Solicitor General’s quo warranto petition questioned her eligibility as Chief Justice. During these parallel actions, Sereno delivered speeches, gave interviews, and participated in public rallies, commenting on the merits of pending judicial proceedings and casting aspersions on colleagues and the institution.

Breach of the Sub Judice Rule and Professional Standards

Sereno’s public statements violated the sub judice rule, which bars extrajudicial comments that may influence judicial proceedings. As both a lawyer and the nation’s top judicial officer, she was bound by CPR Canon 13, Rule 13.02 (prohibiting media statements on pending cases) and NCJC Canons on independence, integrity, impartiality, and propriety.

Show Cause Order and Respondent’s Compliance

On May 11, 2018, the Court ordered Sereno to show cause why she should not be sanctioned for:

  1. Transgressing the sub judice rule.
  2. Casting ill motives on Members of the Court.
    Sereno filed a Verified Compliance and a Motion for Inhibition, arguing that as a party-litigant (not counsel or judge) she was not subject to those standards, and that her statements posed no “clear and present danger” to justice.

Motion for Inhibition

Sereno sought the inhibition of six Associate Justices on alleged bias grounds. The Court, invoking its prior quo warranto decision, held that mere imputation of bias without basis fails to warrant inhibition. The motion was denied.

Obligation of Lawyers and Judges to Uphold Professional Conduct

The Court rejected Sereno’s argument that she should be treated as an ordinary litigant. It reaffirmed that lawyers and judges must maintain high moral character, honesty, and fair dealing at all times. Any conduct—private or professional—that brings reproach on the profession or institution is sanctionable.

Sub Judice Rule and Administrative Discipline

Although the “clear and present danger” test applies in contempt proceedings, administrative discipline for sub judice violations follows from the CPR and NCJC. These codes expressly require lawyers and judges to refrain from public commentary on pending cases.

Violations of CPR and NCJC by Respondent

Sereno’s speeches and interviews contained assertions that:

  • Granting the quo warranto petition would establish a dictatorship and destroy the judiciary.
  • The Court lacked impartiality and would not render a fair decision.
  • Government actors, including the Solicitor General, sought to undermine judicial independence.
    Such statements prejudged the issues, undermined public confidence, and disparaged Members of the Court.
