So you’ve taken your client’s case all the way to the Supreme Court and the justices have asked the solicitor general of the United States whether they should grant review. What are your chances of a nod in your favor?

Not bad, according to an unusual study of two of the high court’s most important “information-gathering” tools — a call for the views of the solicitor general, known as a CVSG, and a call for a response, or CFR, to a petition for certiorari. The Court granted briefing on the merits in 34 percent of cases in which it called for the views of the solicitor general, a 37-time increase above the grant rate for all petitions. And, the justices follow the recommendation of the solicitor general to grant or deny a case roughly 80 percent of the time, according to the study.
