Roberto Reyes Concepción (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, ConcepciĂłn's name was inscribed on the Wall of Remembrance at the Bantayog ng mga Bayani in 1994.ConcepciĂłn formally left the court in 1973 upon reaching the mandatory retirement age.
But in actual practice, he had left 50 days earlier when he took a leave from the court to express dissent over the court's decision in the Ratification Cases (Javellana v.
Executive Secretary (1973)), which upheld the 1973 Constitution, and paved the way for extending Marcos’ regime.
