The Supreme Court (Filipino: Kataas-taasang Hukuman), colloquially referred to as the Korte Suprema (also used in formal writing), is the highest court in the Philippines. It was established by the Taft Commission in June 11, 1901, through the enactment of Act No. 136, which abolished the Real Audiencia of Manila, the predecessor of the Supreme Court.

The Supreme Court compound is located in what was formerly a part of the University of the Philippines Manila campus. It occupies the corner of Padre Faura Street and Taft Avenue in Ermita, Manila, with the main building sited directly in front of Philippine General Hospital's cancer institute.

Prior to the conquest of Spain, the islands of the Philippines were composed of independent barangays, each of which is a community composed of 30 to 100 families. Typically, a barangay is headed by a datu or a local chief who exercises all functions of government: executive, legislative and judicial; he is also the commander-in-chief in times of war. Each barangay has its own laws. Laws may be oral laws, which are the traditions and customs of the locality handed down from generation to generation, or written laws as promulgated by the datu, who is typically aided by a group of elders. In a confederation of barangays, the laws are promulgated by a superior datu with the aid of the inferior datus.

In a resolution of dispute, the datu acts as a judge while a group of elders sits as a jury. If a dispute is between datus or between members of different barangays, the dispute is settled through arbitration with some other datus or elders, from other barangays, serving as arbiters or mediators. All trials are held publicly. When a datu is in doubt as to who between the parties is guilty, the parties are subject to trial by ordeal, this is a common practice in criminal cases. An accused who was innocent was perceived to be always successful in such ordeals. These pre-Hispanic people believed that the deities or gods would aid the innocent accused to survive the ordeal.

In the royal order of August 14, 1569, Miguel López de Legazpi was confirmed as the Governor and Captain-General of the Philippines. He was empowered to administer civil and criminal justice in the islands. Under the same order, Legazpi had original and appellate jurisdiction in all suits and constituted in his person all authority of a department of justice, with complete administrative and governmental control of all judicial offices. In subsequent cédulas and royal orders, it was made the responsibility of all officials to enforce all laws and ordinances issued for the benefits of the locals. This often failed to occur. In a 1583 letter written by Bishop Domingo de Salazar to King Philip II, Bishop Salazar noted different acts of oppression and injustice committed against the native Filipinos and said that the decrees of the King, which were designed to protect them, were generally disregarded by the Governor-General and his subordinates.

As a result of these developments, the first real audiencia (which is the Real Audiencia of Manila) or high court was established in the Philippines through the royal decree of May 5, 1583. The decree stated that "the court is founded in the interests of good government and the administration of justice, with the same authority and preeminence as each of the royal audiencias in the town of Valladolid and the city of Granada. The audiencia was composed of a president, three oidores or auditors, a fiscal or prosecuting attorney, and the necessary auxiliary officials, such as the court's secretaries and clerks. The first president was Governor-Captain General Santiago de Vera.

The Real Audiencia of Manila had a jurisdiction covering Luzon and the rest of the archipelago. It was given an appellate jurisdiction over all civil and criminal cases decided by the governors, alcaldes mayores and other magistrates of the islands. The audiencia may only take cognizance of a civil case in its first instance when, on account of its importance, the amount involved and the dignity of the parties might be tried in a superior court; and of criminal cases which may arise in the place where the audiencia might meet. The decisions of the audiencia in both civil and criminal cases were to be executed without any appeal, except in civil cases were the amount was so large as to justify an appeal to the King; such appeal to the King must be made within one year. All cases were to be decided by a majority vote, and in case of a tie, an advocate was chosen for the determination of the case.

The audiencia would later on be dissolved through the royal cédula of August 9, 1589. The audiencia would later on be reestablished through the royal decree of May 25, 1596, and on May 8, 1598, it had resumed its functions as a high court. By its reestablishment, the audiencia was composed of a president as represented by the governor, four associate justices, prosecuting attorney with the office of protector of the Indians, the assistant prosecuting officers, a reporter, clerk and other officials. By a royal order of March 11, 1776, the audiencia was reorganized; it consisted of the president, a regent, the immediate head of the audiencia, five oidores or associate justices, two assistant prosecuting attorneys, five subordinate officials, and two reporters. It had also been allowed to perform the duties of a probate court in special cases. When the high court is acting as administrative or advisory body, the audiencia acted under the name of real acuerdo. Later on the governor-general was removed as the president of the audiencia and the real acuerdo was abolished by virtue of the royal decree of July 4, 1861. The same royal decree converted the court to a pure judicial body, with its decisions appealable to the Supreme Court of Spain. By the royal decree of October 24, 1870, the audiencia was branched into two chambers; these two branches were later renamed as sala de lo civil and sala de lo criminal by virtue of royal decree of May 23, 1879.
