I'd say that if the law seeks to do us harm, works an evil against us, we must resist it. Likewise with another and if the law seeks to force us to do evil we should also resist.
But Moore is fighting the federal court telling him what he can't forbid another, which is to say he's being denied the ability to enforce his conscience on another. No evil is being worked on anyone, though some are free to work a moral harm against themselves... As someone sworn to serve the law if he cannot in good conscience administer it he should resign his office and protest the law as a citizen can. Else he is actively violating his own oath of office.
I chose undecided because the issue has distinctions of the sort that make the answer vary. And because "unjust" is often a subjective judgment, which would invite anarchy.
