In May 2014, Spirit bassist Mark Andes and a trust acting on behalf of California filed a copyright infringement suit against Led Zeppelin and injunction against the "release of the album containing the song" in an attempt to obtain a writing credit for California, who died in 1997. A lack of resources was cited as one of the reasons that Spirit did not file the suit earlier; according to a friend of California's mother, "Nobody had any money, and they thought the statute of limitations was done... It will be nice if Randy got the credit." If the Spirit lawsuit had been successful, past earnings due to the song—estimated at more than US$550 million—would not have been part of the settlement, but the publisher and composers may have been entitled to a share of future profits.
