If exactly 9 justices vote in favor of the petitioner in Trump v. Slaughter, then the market resolves to Yes. A justice is counted as voting in favor of the petitioner only if, according to the Court's final action, that justice supported a judgment that grants some or all relief requested by the petitioner. The number of votes for the petitioner is the number of justices who concurred in a judgment of the Court in favor of the petitioner, or dissented from the judgment against the petitioner. A justice must participate in the case and take a position aligned with granting relief to the petitioner for their vote to count. <p>If the petitioner prevails in the Court's final judgment, count all justices who joined the majority opinion, wrote or joined concurring opinions, or concurred in the judgment only. A justice who concurs in part and dissents in part will count only if the concurring portion includes a vote to grant the petitioner some relief. If the petitioner loses in the Court's final judgment, count all justices who dissented from the judgment and whose dissent, if adopted, would have granted some or all of the relief the petitioner sought. If a dissenting justice objects only to procedural aspects (e.g., they would have dismissed the case), and their position would not have resulted in granting relief to the petitioner, they are not counted. If the Court affirms in part and reverses in part, count any justice whose vote, opinion, or dissent supports any portion of the judgment that grants relief to the petitioner (e.g., reversal of a lower court ruling adverse to the petitioner).</p> <p>If no majority opinion exists but a judgment is issued, count all justices who concurred in the judgment in favor of the petitioner, regardless of whether they joined the plurality, and count no justice who concurred in the judgment against the petitioner; apply the same principle to dissenters if the petitioner loses. For per curiam opinions, unless otherwise noted, treat unsigned per curiam opinions as representing all participating justices; if any justices issue a dissent or note non-participation, subtract them from the total to calculate votes for the petitioner. If an emergency order is the final disposition of the case, apply the same rules as a per curiam: if the petitioner wins, count all participating justices minus dissents; if the petitioner loses, count all dissenters (those who would have granted relief).</p> <p>If the case is dismissed as improvidently granted (DIG), dismissed for mootness, vacated and remanded without decision, withdrawn or settled, or otherwise concluded without a final merits judgment, then the contract resolves as 0 votes for the petitioner. Even if justices issue separate opinions expressing support for the petitioner, they do not count unless a final judgment is issued. Justices who are recused or who do not participate are excluded from the total count. Only the final votes recorded in the Supreme Court's official slip opinion, summary disposition, or order will be used; leaked drafts or reported internal shifts are not relevant to resolution.</p> This market will close and expire early if the event occurs.
