MANILA (Reuters) – A Philippine senator and the biggest critic of President Rodrigo Duterte filed a “test case” before the Supreme Court on Monday, seeking to fend off what she called harassment by the volatile leader and his public tirades against her.


Leila de Lima, the former justice minister who Duterte’s allies removed as head of a Senate probe into his bloody war on drugs, said she had filed a writ of “habeas data” against the president to protect her privacy and if successful, it could take away some of his immunity.

“This is a test case, a novel case of transcendental importance,” de Lima told reporters. “Habeas data is rarely invoked. We are testing the doctrine of presidential immunity.”

In her petition, de Lima wanted to stop Duterte and his associates from collecting information about her private life and for evidence already gathered to be destroyed.

She also wants the court to stop the outspoken president making public statements that malign her as a woman and, according to the petition, “degrade her dignity as a human being”.

Duterte has verbally attacked de Lima almost daily, during which he has accused her sexual impropriety, among other things.

She faces allegations she had close links to big drug dealers operating in prisons when she was a minister for six years under the previous government. [/restrict]
