This case is before us for the second time. The first time we held, on the apрeal of the plaintiff, that the injunction against the defendants prohibited the sale of gentamicin for therapeutic use in powdered form and not just, as the district court had thought, in liquid form.
That testimony had been excluded in the initiаl hearing before the district court, the hearing that had occurred befоre the first appeal. The defendants had not complained abоut that exclusion. They could, of course, have done so, without even hаving to file a cross-appeal. E.g.,
Massachusetts Mutual Life Ins. Co. v. Ludwig,
Under the dоctrine of the law of the case, a ruling by the trial court, in an earlier stаge of the case, that could have been but was not challenged on appeal is binding in subsequent stages of the ease. E.g.,
Cowgill v. Raymark Industries, Inc.,
The particular wrinkle in the doctrine of the law of the case that is presented by this appeal is novel, but we believe that our conclusion is sound in principle, and it is supported by
United States v. Duchi,
AFFIRMED.
