Maria Lourdes Sereno: Filipino jurist and former Chief Justice

Background and career

Sereno trained in law and worked in a mix of academic, private and public roles prior to joining the Supreme Court. She taught law, participated in legal research and served in government legal assignments. Her appointment to the court reflected a profile combining scholarship, courtroom experience and administrative responsibilities.

Tenure as Chief Justice

As Chief Justice she presided over the court and oversaw administrative functions of the judiciary. Her leadership emphasized access to justice, judicial reforms and efforts to modernize court procedures. Her term coincided with a period of heightened public scrutiny of the judiciary and broader political developments in the country.

Removal and legal controversy

In May 2018 the Supreme Court issued a decision that voided her appointment and removed her from office through a quo warranto proceeding. The court's vote was narrowly divided and its use of quo warranto to displace a sitting chief justice—rather than allowing the constitutionally prescribed impeachment process to proceed to trial—became the focal point of debate. Critics argued the method undermined separation of powers and set a precedent for alternative paths to unseat high officials; supporters contended that the ruling addressed alleged defects in the original appointment.

Reception and significance

• Legal scholars and civic groups offered differing assessments of the ruling's constitutionality and consequences for judicial independence.
• The episode stimulated discussion on the proper remedies for alleged irregularities in appointments and on safeguards for the impartiality of the bench.
• Sereno's removal remains a touchstone in conversations about governance, rule of law, and institutional checks and balances in the Philippines.
