SCOTUS kicked the can down the road.
In this particular case they didn't have to look at anything other than how crappy the commission was; they not only displayed extreme prejudice against the mans religion and failed to uphold the constitutional requirement of not being biased about any religion, but they also failed to look at the evidence that the man was turning away all kinds of stuff he didn't want to work on - like Halloween cakes and the like. The commission on the other hand flew off the PC handle, labeled him as a homophobic bigot and blew their own ruling on the case out of the water.
