RE: Which SCOTUS ruled to be unconstitutional. Which means if Kentucky is still part of the U.S., then it cannot prohibit it (like it or not), not that Kentucky can still keep that until they get around to repealing it.
Which means the SCOTUS made Kentucky marriage law null and void, which means Kim Davis cannot issue a marriage license for a law that the SCOTUS made null and void.
Which means she violated no law.
No it did not anymore when SCOTUS ruled that bans against interracial marriage were unconstitutional did any state prohibiting it all of a sudden have no marriage laws.
Until you can cite for me where they were marriage licenses in those states CEASED until a new law was passed, then you are just playing hard and fast looking for a legal loop-hole that isnt there.
