In brief
Overview
According to Justice Sotomayor, the case raises questions about whether existing federal abstention doctrines, such as the Pullman and Burford doctrines, are sufficient to justify federal abstention here.
According to Justice Alito, the parties discuss the scope of the Tax Injunction Act and whether it limits the doctrine of comity.
According to Mr. Fitch, arguments are made that the dispute involves the dormant Commerce Clause and should be decided in federal court.
