A fairly famous “almost” for self-suit lists is Carter v. Carter Coal Co., which went to the Supreme Court despite being the next thing to a ‘manufactured’ suit. Without researching out the gory details:
Messrs. Carter Sr. and Jr. owned and operated Carter Coal Co. in the 1930s. IIRC Carter Sr. was majority stockholder and Chairman, while Jr. ran day-to-day operations and held some shares. As a business, they were subject to one of the New Deal laws – one that Carter Sr. believed unconstitutional.
So the Carters caused Carter Coal Co. to comply with the statute, including paying in some taxes. Then Carter Sr. sued the company he was majority owner of, and ran along with his son, praying the court to enjoin it from complying with an unconstitutional law.
It was, of course, a strategem for challenging the constitutionality of the New Deal law. But the courts accepted it as a valid “case or controversy.”
