Tesla and Germany’s BMW are suing the European Commission, joining a growing band of Chinese automakers to oppose the European Union on its punitive tariffs on electric vehicles.

Tesla, owned by Elon Musk, is taking the European Union (EU) to court over its tariffs on electric vehicles imported from China. Filed last Wednesday with the European Court of Justice (ECJ) by Tesla’s Shanghai division, the lawsuit comes in the wake of similar legal moves by BMW and other Chinese car manufacturers.

The EU imposed anti-subsidy tariffs of 7.8% on Tesla on top of the 10% levy. BMW’s imports were hit with a 20.7% duty. The firm was hit because its electric Mini Cooper and the 100% electric Mini Aceman are made in China, according to car website Autogear.
