For law students and general practitioners wondering what a DIG is--it means the Court is dismissing a case as improvidently granted. It essentially is like returning a sweater you thought was nice, but once you tried it on you realized it was super itchy or didn't fit well.

The Court does this sometimes when parties shift their positions after cert is granted and don't really argue the issue the Court thought it was agreeing to hear.

Other times, the Court might find some jurisdictional defect it didn't realize existed. Toward the end of the term, we sometimes see DIGs that seem a bit inexplicable (maybe the Court just didn't have time or couldn't come to agreement and don't see a need to resolve now?)

Still other times, it might decide it really would benefit from some more "percolation," or ventilation of the issues in trial and appellate courts, before it resolves them.
