Task: Wrong Candidate Generation
Input (English): that the district court’s mention of having considered the “entire lengthy record” indicates that the court, in concluding that amendment would be both untimely and futile, relied in part upon the overall history of the dispute, including the ease CBS had previously initiated in Florida. Whether the court meant to encompass that history within the reason for its decision is not clear,- however; the “lengthy record” in question may well refer only to the present litigation, which alone had been going on for more than three years at the time. In either event, the district court erred; the prolonged nature of a case does not itself affect whether the plaintiff may amend its complaint. See, e.g., Security Ins. Co. of Hartford v. Kevin Tucker & Assoc., Inc., 64 F.3d 1001 (6th Cir.1995) (<HOLDING>); Buder v. Merrill Lynch, Pierce, Fenner &
