THAPAR, Circuit Judge. For nearly three years, seven sovereigns have been embroiled in negotiations over who gets to manage the Great Lakes fisheries. The merits of those negotiations aren’t before us, only an antecedent question of civil procedure: is the Coalition to Protect Michigan Resources (“the Coalition”) entitled to intervene in those negotiations just as the parties are approaching a deal? Under our precedent, the answer is no. Because the district court properly denied the Coalition’s motion to intervene, we affirm.
