determined by weighing the impetus provided to authors by longer terms against the benefit provided to the public by shorter terms. That weighing is left to Congress, subject to rationality review.

We promoted adoption, support parental notification laws, ended federal funding for abortions overseas, and are funding crisis pregnancy programs. I had the privilege of signing legislation that extends legal protection to children who are born, despite abortion attempts, allows prosecutors to charge those who harm or kill a pregnant woman with harming or killing her unborn child, as well. I signed into law a ban on the cruel practice of partial-birth abortions, and we will vigorously defend that law in the courts.

The Sixth Circuit, along with some other lower courts, adopted several procedural rules designed to implement this exhaustion requirement and facilitate early judicial screening. These rules require a prisoner to allege and demonstrate exhaustion in his complaint, permit suit only against defendants who were identified by the prisoner in his grievance, and require courts to dismiss the entire action if the prisoner fails to satisfy the exhaustion requirement as to any single claim in his complaint. Other lower courts declined to adopt such rules. We granted certiorari to resolve the conflict and now conclude that these rules are not required by the PLRA, and that crafting and imposing them exceeds the proper limits on the judicial role.
