Antonio Tirol Carpio (born October 26, 1949) is an incumbent Senior Associate Justice of the Supreme Court of the Philippines. He was appointed to the Court by President Gloria Macapagal-Arroyo and assumed office on October 26, 2001, his fifty-second birthday.
Born in Davao City, Justice Carpio finished grade school and high school 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 where he graduated valedictorian and cum laude in 1975. He ranked sixth with a rating of 85.70% in the 1975 Philippine Bar Examination.
Fresh out of law school, Justice 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. Justice Carpio also taught Tax Law, Corporate Law, and Negotiable Instruments Law at the U.P. College of Law from 1983 to 1992.
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.
Justice 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.
Justice Carpio has received the Presidential Medal of Merit by then President Fidel Ramos for his "distinguished and exemplary service" to the Republic, 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. In 2015, the University of the Philippines Alumni Association named him Outstanding U.P. Alumni in Public International Law.
Being the Senior Associate Justice, he assumed the post as the Acting Chief Justice in May 29, 2012 until the President appoints 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.
Presently, Senior Associate Justice Carpio is the Chair of the Second Division and Chair of the Senate Electoral Tribunal. He also heads the High Court's Committee on the Revision of the Rules of Court.
South China Sea/West Philippine Sea Dispute
Justice Carpio's personal advocacy is "to protect and preserve Philippine territorial and maritime sovereignty specifically in the West Philippine Sea." 
He believes in the importance of “an understanding by citizens of all claimant states … either to restrain extreme nationalism fueled by historical lies or to give hope to a just and durable settlement of the dispute based not only on the United Nations Convention on the Law of the Sea (UNCLOS) but also on respect for actual historical facts.”
In his speech 'Grand Theft of the Global Commons', Justice Carpio called "...the fishery Regulations of Hainan a grand theft of the global commons in the South China Sea." He also maintains that "The Philippines is fighting a legal battle not only for itself but also for all mankind. A victory for the Philippines is a victory for all States, coastal and landlocked, that China has shut out of the global commons in the South China Sea."
"In recent years [Justice Carpio] has been travelling the world to present Philippines' historical and legal case when it comes to disputed islands in the South China Sea. He has visited 18 countries, 28 key cities."  In May 2015, he traveled to European countries: Humboldt University of Berlin, Faculty of Law in Germany, Institut français des relations internationales (IFRI) in France, International Institute of Social Studies (ISS) in The Hague, and EGMONT - The Royal Institute for International Relations in Belgium to deliver a series of lectures on that topic.
