Whether a defendant may use an “unenumerated Rule 12(b) motion” to obtain a pretrial ruling that a prisoner failed to exhaust administrative remedies under the PLRA.
Holding
No. Except when nonexhaustion is clear from the face of the complaint, the exhaustion defense must be litigated through the ordinary Federal Rules framework, ordinarily by summary judgment under Rule 56.
Reasoning
The Supreme Court held in Jones v. Bock that PLRA exhaustion is an affirmative defense that the defendant must plead and prove. That holding, together with Jones’s instruction not to depart from ordinary federal procedural rules without statutory authorization, undermined Wyatt v. Terhune’s use of an “unenumerated” Rule 12(b) motion—a device not actually provided by the Rules.
In the rare case where the complaint itself conclusively shows that the prisoner did not exhaust and has no valid excuse, dismissal under Rule 12(b)(6) is available. More commonly, because a prisoner need not plead exhaustion, the defendant must submit evidence establishing the affirmative defense and seek summary judgment under Rule 56.
If the evidence, viewed in the prisoner’s favor, establishes nonexhaustion as a matter of law, the defendant receives summary judgment. If material facts remain disputed, summary judgment must be denied; the judge, rather than a jury, then resolves the factual dispute in a preliminary proceeding because exhaustion is a threshold matter of judicial administration, akin in this respect to jurisdiction or venue.
District courts should decide exhaustion as early as feasible and may limit discovery to that issue. On appeal, legal rulings on exhaustion are reviewed de novo, while factual findings made by the judge in a preliminary exhaustion proceeding are reviewed for clear error. The court also indicated that this general approach should govern other nonjudicial-exhaustion contexts previously handled through unenumerated Rule 12(b) motions.
