The discussion at the point you jumped in was only in regard to state minimum wage laws. I was arguing that I didn't see how the Constitution mandated a federal court to stop such a state law.
At the beginning of the discussion I had stated that I could see how federal minimum wage laws were not constitutional, but saw state minimum wage laws as being a non-federal matter. The only relevant constitution being that of the paticular state.
No State shall enter into any Treaty, Alliance, or Confederation; grant Letters of Marque and Reprisal; coin Money; emit Bills of Credit; make any Thing but gold and silver Coin a Tender in Payment of Debts; pass any Bill of Attainder, ex post facto Law, or Law impairing the Obligation of Contracts, or grant any Title of Nobility.
I guess there is a case to be made for not allowing states to have minimum wage...but presumably only in regard to an existing contract obligation.
