The US Supreme Court agreed to hear Bayer AG’s appeal taking aim at thousands of lawsuits targeting its top-selling Roundup weedkiller for causing cancer.

The high court agreed Friday to hear Bayer’s challenge to a $1.25 million Missouri jury verdict against the company’s Monsanto unit over Roundup on the grounds some of the claims in the 2023 case were preempted by federal law. Bayer officials hope the justices’ ruling will help knock out thousands of Roundup cases that include failure-to-warn claims.
