The impeachment bid is the latest twist in a high-profile row among three of the Philippines’ highest office-holders, after the collapse of a powerful alliance between their families led to Marcos’ landslide win in the 2022 election.
“This impeachment is not just a legal battle but a moral crusade to restore dignity and decency to public service,” said Leila de Lima, a spokesperson for the complainants and a staunch critic of an anti-narcotics campaign run by Duterte’s father.
The complaint accused Duterte of violating the Philippine constitution by refusing to attend hearings on her budget which violated the system of checks and balances, and graft, both as vice president’s office and when she was the education minister.
It also accused her of gross incompetence and dereliction of duty.
Sara Duterte recently said she had contracted someone to kill Marcos, his wife and House Speaker Martin Romualdez, the president’s cousin, if she herself were to be killed. Later, she said the remarks had been taken out of context.
On Friday, in remarks that drew criticism from some lawmakers, Marcos said any impeachment complaint against his estranged vice president would only distract Congress and not help people.
The Philippines’ lower chamber of congress is dominated by allies of Marcos, which could allow her impeachment to go through the lower chamber before an impeachment trial in the Senate.
