Eventually public outcries after the election results came out with Marcos winning led to the 1986 People Power Revolution that peacefully ousted the Marcos family out of the country. Diokno was appointed by the new President Corazon Cojuangco-Aquino or "Cory", wife of the slain "Ninoy" Aquino and mother of the future 15th president, Benigno ""Noynoy"" Aquino, to serve as founding chairman of the Presidential Committee on Human Rights, now the Commission on Human Rights (CHR), and tasked to lead a government panel to negotiate for the return of rebel forces to the government folds. Diokno helped write the 1987 Constitution, particularly Article XIII defining social justice and human rights. Diokno was also the principal negotiator in peace talks with the National Democratic Front of the Philippines, the main leftist coalition founded during martial law. Not long after his return to politics, Diokno resigned in January 1987 after farmers who peacefully protested were slain by state security forces. According to Diokno's daughter "Maris", it was the only time he was seen to be near tears.
