The Supreme Court has agreed to hear Bayer's appeal to block thousands of lawsuits alleging its Roundup weedkiller causes cancer. The court will consider whether the EPA's approval of Roundup without a cancer warning should preempt state court claims. This case stems from a Missouri lawsuit where a man was awarded $1.25 million after developing non-Hodgkin's lymphoma from Roundup exposure. Bayer, facing approximately 181,000 Roundup claims, argues that conflicting lower court rulings warrant Supreme Court intervention, citing a 2024 ruling in its favor by the 3rd U.S. Circuit Court of Appeals. The Trump administration supports Bayer's position, differing from the Biden administration's stance.
