Roberto Concepcion

After the toppling of Marcos from power, Concepcion was appointed as one of the commissioners tasked to draft the 1987 Philippine Constitution. As one of its members, he is responsible for crafting the contents regarding civil liberties, as well as an added provision in the Executive Powers of the President, a clause limiting the effects of martial law with respect to the writ of habeas corpus, based on one of the decided cases of the Supreme Court in which he wrote. As chairman of the Judiciary Committee, he was responsible for introducing provisions designed to strengthen the independence of the judiciary, which was clearly abused by the Marcos regime.

Concepcion formally left the court in 1973 upon reaching the mandatory retirement age but had, in reality, taken leave of absence 50 days earlier to express his dissent over the court's decision in the Ratification Cases, which upheld the 1973 Constitution, and paved the way for extending Marcos' regime.

Concepcion wrote the decision in the Ratification Cases which upheld the 1973 Constitution. In the said decision, he wrote the summary of facts, then his own opinion of the case (which he said that the 1973 Constitution has not been properly ratified according to law), then proceeded to make the summary of votes.

The court was divided on the issues raised in the petition: but when the question of whether the petitioners in the cases are entitled to relief, Concepcion, together with three others answered ‘Yes’, while six other members denied the relief being sought, thus upholding the 1973 Constitution and made legitimate the rule of Marcos.

Javellana v. Executive Secretary (G.R. No. L-36142, March 31, 1973; 50 SCRA 30): Concepción's last ponencia, he formally delivered the summary of votes in upholding the 1973 Philippine Constitution, but delivered in his own opinion his disapproval that the said Constitution was in effect and ratified properly by the Filipino people.

Lansang v. Garcia (G.R. No. L-33964, December 11, 1971; 42 SCRA 448): The Supreme Court, through Concepcion, while it upheld the suspension of the writ of habeas corpus by Marcos, declared that the Judiciary has the authority to inquire to the factual basis of such suspension, and that the suspension is to be annulled if no legal ground would be established. This doctrine is now established by the 1987 Philippine Constitution as it is included in one of its provisions.

Stonehill v. Diokno (G.R. No. L-19550, June 19, 1967; 20 SCRA 383): It was ruled that the articles that were seized illegally by the government cannot be used as admissible evidence, thus adopting the fruit of the poisonous tree doctrine in Philippine jurisdiction. It abrogated the principle established in an earlier case (Moncado v. People's Court, 80 Phil. Reports 1). During the time between the Moncado and Stonehill decisions, Concepcion dissented in every case which would uphold the admissibility illegally seized evidence, citing the U.S. cases of Weeks v. U.S.(232 U.S. 383, 1920) and Elkins v. U.S.(364 U.S. 206, 1960). Said case also established the definition of probable cause, which requires that allegations should be specific in the description of the offense or crime committed, as well as to the evidence subject of the search warrant.

People v. Hernandez (99 Phil. Reports 515, 1956): the Supreme Court, through then Associate Justice Concepcion, ruled that rebellion cannot be complexed with other crimes, such as murder and arson. Rebellion in itself would include and absorb the said crimes, thus granting the accused his right to bail.

He graduated his Bachelor of Laws with summa cum laude from the University of Santo Tomas in 1924, then placed first in the bar examinations that same year. Starting out as a private practitioner for only four years, he then worked at the Office of the Solicitor General as an assistant, from which he was subsequently appointed as a judge of the Court of First Instance in 1940, then a Court of Appeals Justice in 1946 before being appointed as Supreme Court Associate Justice in 1954.

Roberto Reyes Concepcion (June 7, 1903 – May 3, 1987) was the Chief Justice of the Supreme Court of the Philippines from June 17, 1966 until April 18, 1973. He is remembered in the history of the Philippine Supreme Court for protecting the independence of court, and for having fought decisions which would have legitimized the dictatorship of President Ferdinand Marcos. In recognition of his efforts against authoritarian rule, Concepcion's name was inscribed on the Wall of Remembrance at the Bantayog ng mga Bayani in 1994.

Concepcion was born in Manila on June 7, 1903 to Isidro Concepcion and Catalina Reyes.
