Enforcing the terms of a consent decree borne of a “blood oath” undertaken 40 years ago by the surviving members of Lynyrd Skynyrd, a Manhattan federal judge has ruled the band's former drummer can never produce a biopic about the band's final years.

The permanent injunction, issued Monday, was not the first time that U.S. District Judge Robert Sweet of the Southern District of New York has donned his robe to preside over legal matters involving the Southern rock band, which was formed in Jacksonville, Florida, in the 1960s.

In 1988, Sweet approved a consent order establishing restrictions on how the band's name could be used, as well as how its history could be told.
