Jerry,
So far the idea of discriminatory permit access has been challenged in five states. The NY, NJ and MD cases are all in different circuits (2nd/3rd/4th) and all three lost at the three-judge circuit panel stage - those courts said discriminatory permit issuance was OK. All three were appealed to the US Supreme Court who declined to hear all three.
Three different cases arising in two California counties and Hawaii were heard in the 9th circuit, in the Peruta case. The Peruta panel ruled our way!!! That happened after the NY/NJ/MD cases were declined by The Supremes. (State courts in Puerto Rico also ruled against discriminatory permit issuance.)
Therefore, the Peruta case created a "circuit split" - different federal circuits disagreeing with each other. That increases the odds that the next time the Supremes get a shot at deciding the difference, they will.
But there's a problem: the Peruta case is being appealed "en banc", which basically means we may see an 11-judge panel called to 2nd guess the 3-judge panel. We don't know if that's going to happen or not, or if an en banc panel does reviewed it whether they'll turn against or support the three-judge panel. So the "circuit split" could collapse, which would be bad. Even if it holds, there's no guarantee that either of the losing states (Hawaii or California) will then appeal their final 9th circuit loss to The Supremes.
Another question is, what case could possibly come up to deal with this issue? Outside of the 9th circuit and the 2nd/3rd/4th circuits, most states don't do this kind of BS...can't mount a challenge in the 5th circuit because Texas and the other states that form the 5th don't do this.
There's only two remaining choices: the 1st circuit where Massachusetts does discriminatory permits and the DC Court of Appeals which is it's own "circuit". I think something is slowly progressing in Mass. so that leaves DC as a battleground.
Even if Peruta fails (for our side) en banc and The Supremes decline to hear it, there's a pretty good chance the DC Appellate court will go our way and if so, that would be a case going to The Supremes on a circuit split which is what we want.
We want it quick, too, because the thought of a Supreme Court after President Hillary (ack!) gets ahold of it is too grim for words.
