I think you misunderstand - California outlawed non-competes by passing a law, not by interpreting the US/California constitution. It was not the judicial branch that outlawed them, but the legislative one. I.e., to do it the same way California did it, would mean passing a new federal law, not a new ruling along constitutional grounds.
