The marble facade of the U.S. Supreme Court building proclaims a high ideal: "Equal Justice Under Law."

But inside, an elite cadre of lawyers has emerged as first among equals, giving their clients a disproportionate chance to influence the law of the land.

A Reuters examination of nine years of cases shows that 66 of the 17,000 lawyers who petitioned the Supreme Court succeeded at getting their clients' appeals heard at a remarkable rate. Their appeals were at least six times more likely to be accepted by the court than were all others filed by private lawyers during that period.
