Ben & Jerry’s has sued its parent company, Unilever, claiming they have been censored from “publicly voicing support for peace and refugee rights,” in particular their support for Palestinian refugees.

Ben & Jerry’s said in the lawsuit it has tried to call for a ceasefire, support the safe passage of Palestinian refugees to Britain, back students protesting at US colleges against civilian deaths in Gaza, and advocate for a halt in US military aid to Israel. The court filing was first reported by Reuters.

Ben & Jerry’s has claimed Unilever threatened to dismantle its independent board and “silenced” the brand over its support for Palestinian refugees, in the latest legal flare-up between the ice cream brand and its parent company.
