On March 14, 2025, the Supreme Court of Texas denied mandamus relief in a controversial qui tam case. The decision was a setback for WLF, which filed an amicus brief with the court urging mandamus. WLF argued that if the government chooses to share its treble-damages claims with private qui tam relators, the government must also share the consequences—and that means holding the government to the same preclusion rules that apply to any litigant. Otherwise, qui tam relators could repeatedly sue, voluntarily dismiss, and never face preclusion. WLF’s amicus brief was prepared with the generous pro bono assistance of Allyson Ho, Bradley Hubbard, Benjamin Wilson, Jason Muehlhoff, and Catherine Frappier of Gibson, Dunn & Crutcher LLP.
