In an unusual filing with the Supreme Court this week, Acting Solicitor General Neal Katyal said some of the information that the Court used in its recent Graham v. Florida decision, supplied to the Court by a federal official without the SG’s knowledge, was inaccurate.

In the landmark decision May 17, the high court ruled that the Eighth Amendment bars the sentencing of juveniles to life in prison without the possibility of parole for non-homicide crimes.
