"It would be an unwarranted judicial intrusion into this pervasively regulated area for federal courts to issue injunctions imposing deadlines with respect to future disability claims." Suit for injunction requiring Social Security Administration to adjudicate claims for disability benefits without further delay could not be litigated as class action, as any delays could be analyzed for reasonableness only in context of individual cases.

Court abolished judicially imposed mandatory time limits for ALJ hearings and decisions because they fail to take into account the differences in the facts and circumstances of each individual case. Delays may be analyzed for reasonableness only in the context of individual cases, and so any class-wide time requirements are inappropriate.
