Bd. of Educ., 228 F.2d 853, 857 (6th Cir.1956); accord id. at 859 (Stewart, J., concurring); id. at 860 (Miller, J., dissenting). This implies that we review only for abuse of discretion. Nevertheless, although the court below had discretion regarding whether to grant a broader injunction or not, it abused this discretion when it failed to address the issue at all. Cf. Foman v. Davis, 371 U.S. 178, 182, 83 S.Ct. 227, 230, 9 L.Ed.2d 222 (1962) (“The grant or denial of an opportunity to amend is within the discretion of the District Court, but outright refusal to grant the leave without any justifying reason appearing for the denial is not an exercise of discretion; it is merely abuse of that discretion.”); Glover v. Johnson, 855 F.2d 277, 284 (6th Cir.1988) (<HOLDING>). Plaintiffs briefed the merits of their sewer
