The "legal laws" line definitely has redundancy. He should have written "Those are the regal laws", which would work (to a degree...except that the laws of nature wouldn't have stemmed from the king, except by magic possibly worked at his command).
I think the line about the "bold cavalier" was written for the abridged album version, to work as a song out of context; as I recall from the libretto, the onstage version was always "Out the room..." etc.
