Read the opinion. The court summarized its ruling this way:
Community Financial Services Association of America and Consumer Service Alliance of Texas challenge the validity of the Consumer Financial Protection Bureau’s 2017 Payday Lending Rule. The Plaintiffs contend … that the Bureau is unconstitutionally structured. [We agree with the Pplaintiffs that] Congress’s decision to abdicate its appropriations power under the Constitution, i.e., to cede its power of the purse to the Bureau, violates the Constitution’s structural separation of powers. We thus reverse the judgment of the district court, render judgment in favor of the Plaintiffs, and vacate the Bureau’s 2017 Payday Lending Rule.
