MANILA (AFP) - Philippine drug war critic Leila de Lima was a highly paid lawyer who switched focus mid-career to human rights, a decision that would draw her into the deadly world of President Rodrigo Duterte.
De Lima was arrested on Friday (Feb 24) on drug trafficking charges which she insisted were manufactured to silence her opposition to Duterte's anti-crime crackdown, which has claimed more than 6,500 lives in eight months.
De Lima, 57, began her career as one of the brightest legal prospects in the Philippines, having scored the eighth highest mark in the country's annual lawyer licence exams in 1985.
She worked as a law clerk for the House of Representatives and as a legal aide of a Supreme Court associate justice, while building a successful law practice that specialised in helping prominent politicians in election court challenges.
De Lima helped now-Senate President Aquilino Pimentel Jnr to unseat a senate election rival, and future senator Alan Peter Cayetano beat a suit alleging he was not a Filipino citizen and therefore not qualified to run for office.
Ironically, Pimentel and Cayetano are now among the most powerful allies of Duterte, a longtime mayor of the southern city of Davao who won presidential elections last year after promising to kill tens of thousands of criminals.
De Lima's life turned in 2008 when she accepted her first government post as chairwoman of the government's independent Commission on Human Rights.
During two years in the job, she worked with a small team of lowly paid lawyers, investigating extrajudicial killings, abductions and human rights violations by the Philippines' notoriously corrupt security forces.
Another one of her main targets was Duterte, who had for years faced allegations of running death squads in Davao that killed hundreds of drug addicts and petty criminals as part of a ruthless anti-crime campaign.
De Lima opened a probe into the so-called Davao Death Squads.
She left the commission with the probe unfinished in 2010 to become justice secretary in the administration of Benigno Aquino, who swept to power on a pledge to fight corruption.
As justice secretary, she prosecuted cases linked to the misuse of huge amounts of legislators' so-called pork-barrel funds, and raided the country's biggest prison to dismantle the perks accorded to inmates convicted of drug offences.
She left the cabinet in late 2015 to run for the Senate, winning a seat last year at the same time Duterte was elected president.
As Duterte launched a Davao-style anti-crime crackdown that would go on to claim thousands of lives, De Lima was one of the few politicians willing to criticise him.
"I will have to destroy her in public," Duterte said in August last year, then proceeded to build a case alleging she was one of the nation's biggest drug traffickers.
"Throughout my entire life, I never imagined myself becoming a victim of a human rights violation myself," De Lima, a divorced mother-of-two, said in October as she insisted the charges against her were absurd.
