The pharmaceutical industry's leading lobby group is suing California to block enforcement of a new law that requires manufacturers to make public disclosures about substantial hikes in the costs of drugs.

The Pharmaceutical Research and Manufacturers of America, represented by Arnold & Porter Kaye Scholer and Downey Brand, sued the state Dec. 8 in the U.S. District Court for the Eastern District of California.

“The new law imposes nationwide restrictions on the list price of pharmaceutical manufacturers' products. It penalizes manufacturers for conduct that occurs exclusively outside California,” according to the complaint. PhRMA wants an injunction stopping enforcement of the law, and a declaration that the law is unconstitutional.
