Gibson, Dunn & Crutcher on Monday lost its bid for $800,000 in legal fees for the firm’s pro bono victory in a major separation-of-powers challenge in the U.S. Supreme Court.

The U.S. Court of Appeals for the D.C. Circuit, in an order issued without comment, rejected the fee request in the case Lucia v. SEC. Chief Judge Merrick Garland and Judges Gregory Katsas and Neomi Rao did not participate in the decision. The total fee request amounted to $818,730.80 for more than 4,000 hours of work.
