Kathaleen McCormick is a judge at the Court of Chancery in the US state of Delaware. She cut Elon Musk's billion-dollar salary at Tesla - and with it the title of the richest person in the world.

Musk now wants to move to Texas with Tesla, as he announced via his short message service X, formerly Twitter. Musk can appeal the ruling to the Delaware Supreme Court. For now, however, he left it with attacks on his opponent: He disparagingly calls McCormick an activist, a politician.
