William was a quiet and unexceptional teenager, quite short for his age. He was a college sophomore when Ferdinand Marcos imposed martial law. He became an activist, revealing previously unseen gifts and skills.
He turned out to be an exceptionally daring person. He joined rallies and protests which Marcos had banned under martial law. In one occasion, soldiers hunted for him in La Salle, and he had to hide in the car trunk of one of the more understanding teachers so he could leave the campus.
He was also resourceful. Soldiers came to raid his family’s apartment house looking for him and threatened the family if they did not reveal his whereabouts. William asked help from a school friend, who was a general’s son, and suddenly, he was not being hunted anymore. In his senior year, he became editor of the campus paper The La Sallian, and he showed a keen writing ability.
He moved to the University of the Philippines to pursue his law degree, joining the fraternity Scintilla Juris. He continued to write critical articles, contributing them to Nassa News, a church newsletter that had become one of the most valued outlets for views and news about the anti-martial law resistance. The stories about the sufferings of sugar workers in Negros province made a huge impact on him. He began to see the role he could play as a lawyer for poor people. Among his idols were the late senator Jose W. Diokno.
He married his college sweetheart Betty, then graduated in 1983, the year the late senator Benigno Aquino Jr. was killed. As he started his law practice, William joined the Movement of Attorneys for Brotherhood, Integrity, Nationalism, Inc. (MABINI) and immediately started representing laborers and human rights victims in court.
He helped publish a satirical newsletter called Sick of the Times, whose biting essays and editorial cartoons made fun of the dictatorship and its abuses. One of the most memorable articles in the newsletter is a satire on an ailing president. The article was titled “Autumn of the Patriarch,” taken from another article written by Colombian writer and journalist, Gabriel Garcia Marquez. The newsletter was witty, funny, irreverent, defiant, and with a funny sense of the absurd, so much like him.
After the fall of the Marcos dictatorship, William turned his attention to exposing and prosecuting corruption and crime. He served as legal counsel for the non government Citizens’ Action Against Crime, taking up mostly pro bono cases of kidnap victims.
