This market will resolve to "YES" if the Supreme Court allows both of the regulations at issue in the Garland v. VanDerStok case to go into effect. This resolves to "NO" if the court issues any judgment that bars the ATF from enforcing either of the regulations at issue in the case. To be clear, 

 that prevents the regulations from going into effect resolves the market to "NO".

To preserve the integrity of this market as a forum for predictions, the market may close anytime the Supreme Court is issuing opinions and then reopen after it has finished, provided that the opinion in this case has not issued.

Should there be a dispute, the rules provided will control over the answer to the question itself.

 While, the question is intended to provide an easy way for people to bet on their beliefs, it is not the end all be all, and all traders should look at the rules. The unlikely event of significant ambiguity regarding whether the resolution criteria have been met. I reserve the right to resolve a question to a percentage that I deem fair. I will give notice before I do this.

Note: due to posible ambiguity I will not trade on this market.
