As of April 5, 2021, the position is currently held by Alexander Gesmundo, who was appointed by President Rodrigo Duterte following the early retirement of his predecessor, Diosdado Peralta, in March 2021.

The chief justice, who was first named on June 11, 1901, in the person of Cayetano Arellano, is the oldest existing major governmental office continually held by a Filipino, preceding the presidency and vice presidency (1935), senators (1916, or as the Taft Commission, on September 1, 1901) and the members of the House of Representatives (1907 as the Philippine Assembly).

The power to appoint the chief justice lies with the president of the Philippines, who makes the selection from a list of three nominees prepared by the Judicial and Bar Council.

Due to the exceptional political circumstances culminating in the People Power Revolution, on February 25, 1986, Corazon Aquino took her oath of office as president before Associate Justice Claudio Teehankee in San Juan just minutes before Ferdinand Marcos took his own oath of office also as president before Chief Justice Ramon Aquino.

Six years later, in 2016, Rodrigo Duterte took his oath of office before Associate Justice Bienvenido Reyes, his classmate at San Beda College of Law, instead of Chief Justice Maria Lourdes Sereno (who would eventually be removed from her position through quo warranto after it was determined that she had been unlawfully holding office ab initio).
