Lawyers for the City of Oakland are crying foul that antitrust lawyers at the Department of Justice are attempting to back the National Football League in the city’s lawsuit over the Raiders’ upcoming relocation to Las Vegas.

The city sued the Raiders, the NFL and its remaining 31 teams late last year claiming that they conspired to “boycott” Oakland in violation of federal antitrust laws and in breach of the league’s own relocation policies in signing off on the team’s move to Las Vegas. In particular, the city claims the $378 million “relocation fee” that the team paid to the league’s other team owners acted as “supra-competitive cartel payments.”
