In Graham County Soil & Water Conservation District v. U.S. ex rel. Wilson, decided today, the Supreme Court in an opinion by Justice Thomas concluded that the statute of limitations for retaliation claims under the False Claims Act is to be borrowed from state law, and the six-year statute from 31 U.S.C. § 3731(b)(1) does not apply.
As written here and here, this was the case argued in part by Abingdon lawyer Mark Hurt. I'm sure he is bummed but five or ten or fifty years from now, he'll still be able to tell the tale of arguing before the U.S. Supreme Court.
