The decision in Joseph v. Lynch does not contain any particularly enlightening legal principles (except to confirm that the 7th Circuit will not exercise jurisdiction to review motions to reopen filed on purely discretionary grounds), but if you'd like to read the saga a man who has filed 8 motions to reopen, I recommend the case. Mr. Joseph did not receive the relief he was seeking, but he shown an unusual level of persistence, and perhaps will try again.
