Restaurant group Illegal Pete’s Inc. has sued two state officials in federal court over their refusal to convert the Colorado-based company to a Delaware limited liability company, arguing they based their decision on the notion that its “name has a negative connotation.”

The lawsuit, filed Monday, accused Deputy Secretary of State Kristopher Knight and Margaret Magnusen, the corporations section manager of the state division of corporations, of violating its constitutional rights with the decision late last year. The filing was first reported by the Associated Press on Tuesday.
