U.S. Chamber files coalition amicus brief

March 28, 2023

The coalition amicus brief urges the Supreme Court to hold that if a defendant’s conduct was consistent with an objectively reasonable interpretation of an ambiguous provision, the defendant cannot be liable under the False Claims Act unless authoritative guidance warned the defendant away from that interpretation.

John P. Elwood, Craig D. Margolis, Christian D. Sheehan, and Jayce Born of Arnold & Porter Kaye Scholer LLP and the U.S. Chamber’s Litigation Center served as co-counsel for the U.S. Chamber.
