Antonio Carpio

In May 2017, Carpio published an eBook titled "The South China Sea Dispute: Philippine Sovereign Rights and Jurisdiction in the West Philippine Sea". The book collects over 140 lectures and speeches by Carpio "intended to convince the Chinese people that the nine-dashed line has no legal or historical basis." The eBook "explains in layman’s language the South China Sea dispute from A to Z."

In 2015, the Philippine Department of Foreign Affairs sponsored Carpio on a world lecture tour on the South China Sea dispute. Carpio presented the Philippines' historical and legal case on the dispute before think tanks and universities in 30 cities covering 17 countries.

Being the senior associate justice, he assumed the post of acting chief justice on May 29, 2012, until the president appointed a new chief justice. He assumed the post after his predecessor, Renato Corona, was convicted by the Senate impeachment court for his failure to disclose in his Statement of Assets, Liabilities, and Net Worth, dollar accounts that led to his removal in office, a penalty authorized by the 1987 Constitution. He assumed the post again on March 1, 2018, as Chief Justice Maria Lourdes Sereno filed an indefinite leave in the midst of impeachment proceedings against her.

Carpio was the first appointee of President Gloria Macapagal Arroyo to the Supreme Court of the Philippines after her assumption into office in January 2001. At the age of 52, he was one of the youngest appointees to the High Court.

Carpio received the Presidential Medal of Merit from President Fidel Ramos in 1998 for his "distinguished and exemplary service" to the country, the Outstanding Achievement in Law Award from the Ateneo de Manila Alumni Association, and an honorary Doctorate of Laws from the Ateneo de Davao University. The University of the Philippines Alumni Association named him Outstanding U.P. Alumni in Public International Law in 2015 and the Most Distinguished Alumni in 2017.

In 1992, he joined the administration of President Fidel Ramos as chief presidential legal counsel of the Office of the President. As such, he worked for major reforms in telecommunications, shipping, civil aviation, and insurance industries. During the presidency of Joseph Estrada, Carpio returned to private practice and penned a regular opinion column published in the Philippine Daily Inquirer.

After law school, Carpio went into private practice and founded the Carpio Villaraza and Cruz law firm. He soon emerged as one of the more prominent and successful legal practitioners in the country. Carpio also taught tax law, corporate law, and negotiable instruments law at the UP College of Law from 1983 to 1992.

Born in Davao City to Bernardo Dumlao Carpio and Sol Gonzales Tirol, Carpio finished his elementary and secondary education at the Ateneo de Davao University. He obtained his undergraduate degree in Economics from the Ateneo de Manila University in 1970 and his law degree from the University of the Philippines College of Law at UP Diliman where he graduated valedictorian and cum laude in 1975. He ranked sixth with a rating of 85.70% in the 1975 Philippine Bar Examination.
