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, any resolution 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 will 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.
@Quroe Yes. However, I should note that any decision including a decision to dismiss the case from the court's docket will be sufficient to resolve the question.
