WATCH: Gadon hurls expletives, flashes middle finger at Sereno supporters

MANILA, Philippines — Lawyer Larry Gadon on Tuesday cursed and raised a middle finger at the supporters of Chief Justice Maria Lourdes Sereno, who picketed at the Supreme Court’s compound in Baguio City.

The lawyer, who filed the impeachment complaint against Sereno at the House of Representatives, repeatedly called the Sereno's supporters “stupid” when he encountered them at the high court’s Baguio compound hours before the oral arguments on a separate ouster petition that Solicitor General Jose Calida filed against the chief justice.

He also called someone a “son of a b****” in response to being called “stupid.”

“They are stupid. It is very clear that Sereno committed violations and yet they’re staging a rally,” Gadon said.

The 14-member court, headed by Acting Chief Justice Antonio Carpio, is set to hold oral debates on the quo warranto petition at 2 p.m.
