Grayson, this is is from the TN Rules of Civil Procedure, and deals with STANDING;
17.01. Real Party in Interest. — Every action shall be prosecuted in the name of the real party in interest; but an executor, administrator, guardian, bailee, trustee of an express trust, a party to whose rights another is subrogated, a party with whom or in whose name a contract has been made for the benefit of another, or a party authorized by statute may sue in his or her own name without joining the party for whose benefit the action is brought; and when a statute so provides an action for the use or benefit of another shall be brought in the name of this state. No action shall be dismissed on the ground that it is not prosecuted in the name of the real party in interest until a reasonable time has been allowed after objection for ratification or commencement by, or joinder or substitution of, the real party in interest; and such ratification, joinder, or substitution shall have the same effect as if the action had been commenced in the name of the real party in interest.
Visit a library where they have the TN laws, it does not have to be a law library, maybe the main branch of the county.
In the Rules volumes, look up the above. After will be case law Annotations, see if any help.
One can only sue for another in fact specific cases. A parent can sue for thier minor, etc, even though the parent was not 'harmed/injured". By injured/injury is meant a violation of law, etc., not necessarily injury from assault etc.
In contrast to constitutional violations, one person can NOT assert the rights of another, that is well settled law.
One current example of standing, at least Article 3 Standing, was the Newdow case out of CA.
He sued for his daughter as her "next of friend" they term it, to have "One Nation under God" removed from the Pledge of allegience as he was an athiest and she had to recite it everday in class.
It went to the US SC, they dismissed it, as he was not the custodial parent, therefore he had NO Standing to file suit for her.
I know we are dealing with state standing here, but I cite it just as an example.
