Teresita de Castro

De Castro officially retired on October 10, 2018, after reaching the mandatory retirement age of 70; merely 46 days after serving as Chief Justice, surpassing the record of former Chief Justice Pedro Yap of being the shortest-tenured Chief Justice.

On August 25, 2018, President Duterte announced his appointment of Justice De Castro as the new Chief Justice of the Supreme Court, replacing Maria Lourdes Sereno who was removed from office by way of an 8–6 decision by the Supreme Court over a quo warranto petition. She formally assumed the office on August 28.

On August 25, 2018, De Castro was appointed by President Rodrigo Duterte as the Chief Justice of the Supreme Court, following the ouster of Maria Lourdes Sereno via quo warranto. She served 46 days until her mandatory retirement on her 70th birthday on 10 October. De Castro's appointment was criticized due to her expected short term of two months since she is obligated to retire on October 8, 2018, as well as her role as one of the five sitting justices who sought to nullify the appointment of Sereno as Chief Justice.

She held the position of President-elect of the International Association of Women Judges (IAWJ) from 2012 to 2014. She is also the Chairwoman of the 2015 Philippine Bar Examination committee.

De Castro was one of five sitting justices who sought to nullify the appointment of Maria Lourdes Sereno as the country's top magistrate. De Castro and Sereno were both shortlisted by the Judicial and Bar Council in 2012 for the Chief Justiceship but then-President Benigno Aquino III appointed the latter to the post. Along with four other members, she was accused of exhausting legal remedies to oust the incumbent Chief Justice.

De Castro headed the anti-graft court's special division on the perjury and plunder trial of former President Joseph Estrada. Estrada's son, Senator Jinggoy Estrada also faced charges. The trial finished in September 2007. Estrada was acquitted of perjury charges but found guilty of plunder and sentenced to life imprisonment. All the co-defendants, including Senator Jinggoy Estrada, were acquitted of all charges.

On October 16, 2007, the Judicial and Bar Council (JBC) announced the final nominees to the Associate Justice Cancio Garcia's vacant Supreme Court of the Philippines Associate Justice post. Teresita De Castro, Justices Edgardo Cruz and Martin Villarama, got 7 out of 8 votes, while Associate Justices Francisco Villaruz and Edilberto G. Sandoval and Labor Secretary Arturo D. Brion got 5 votes each (from the JBC). Under Philippine law, the President has 90 days to choose from among the final nominees.

De Castro was sworn before Chief Justice Reynato S. Puno on December 4, 2007. Teresita de Castro stated: "Everything happens in God's time. I believe that my 34 years of service in the judiciary and a good track record make me qualified for this position." Immediately after being sworn in, she participated in her first en banc session.

De Castro became controversial when she was the Sandiganbayan's Presiding Justice after her Division convicted former President Joseph Estrada for graft. Many believed that her decision was related to her subsequent appointment by former President Gloria Macapagal Arroyo as the 160th Associate Justice of the Supreme Court in 2007 in exchange of her favorable decision.

She started her judicial career as a law clerk, legal and judicial assistant in the Supreme Court of the Philippines,(1973–1978). She was appointed DOJ State Counsel I and II (1978–1985), and promoted to senior state counsel (1985–1987), supervising state counsel, and chief of the Legal Staff (1988–1989). Before her Sandiganbayan appointment, De Castro was State Counsel V and Legal Staff head at the DOJ (1989–1995). De Castro was the Presiding Justice and Chair of the First Division, Sandiganbayan at the time of her appointment to the High Court.

De Castro finished her grade school (1960) and high school education (valedictorian, 1964) at St. Paul College of Parañaque, and earned her political science degree (cum laude, 1968) and Bachelor of Laws (1972) at the University of the Philippines. She passed the Philippine Bar Examination of November, 1972 with bar rating of 80.9%.
