Enough parties at the party

National Casualty sued its insured in federal court for a declaratory judgment that there was no coverage.  The insured sued National Casualty and the insured’s insurance brokers in state court for misleading it about coverage.  The district court found that those additional parties were indispensable for the federal action (and would destroy diversity if joined), and abstained under Colorado River from proceeding further.  Reminding “that it is not necessary for all joint tortfeasors to be named as defendants in a single lawsuit,” the Fifth Circuit reversed as to the joinder analysis, and also as to abstention, noting in particular that “the federal action has proceeded to summary judgment . . . [and] the state court action has involved little more than an original petition, answers, and a stay of proceedings.”  National Casualty Co. v. Gonzalez, No. 15-10478 (Feb. 4, 2016, unpublished).
