Weedkiller maker asks U.S. Supreme Court to block lawsuits claiming it failed to warn about cancer
Bayer has asked the U.S. Supreme Court to decide whether federal law preempts thousands of state lawsuits alleging it failed to warn people that its popular weedkiller could cause cancer.

JEFFERSON CITY, Mo. — Global agrochemical manufacturer Bayer has asked the U.S. Supreme Court to decide whether federal law preempts thousands of state lawsuits alleging it failed to warn people that its popular weedkiller could cause cancer.
Bayer’s new request to the nation’s highest court comes as it is simultaneously pursing legislation in several states seeking to erect a legal shield against lawsuits targeting Roundup, a commonly used weedkiller for both farms and homes. Bayer disputes the cancer claims but has set aside $16 billion to settle cases and asserted Monday that the future of American agriculture is at stake.
