A fresh petition has been filed against Deputy Chief Justice Philomena Mwilu seeking her removal from the powerful position and her seat at the Supreme Court.

Mwilu's woes stem from her decision to empanel a three-judge bench to hear and determine a case by former Deputy President Rigathi Gachagua challenging his impeachment.

The move made last year was ruled to be beyond the scope of her powers on Friday.

The petition filed by Belinda Egesa on Tuesday, May 13, argued that Mwilu demonstrated incompetence by misinterpreting Article 165(4) of the Constitution on the powers of the DCJ to assign judges in an expanded bench dealing with a case raising substantial questions of law.
