Ben & Jerry’s says its CEO was unlawfully removed by its parent company, Unilever, in retaliation for the ice cream maker’s social and political activism. In a federal court filing late Tuesday, Ben & Jerry’s said Unilever informed its board on March 3 that it was removing and replacing Ben & Jerry’s CEO David Stever. Ben & Jerry’s said that violated its merger agreement with Unilever, which states that any decisions regarding a CEO’s removal must come after a consultation with an advisory committee from Ben & Jerry’s board.
