Supreme Court curbs state cancer warnings for pesticides when EPA stays silent

The Supreme Court ruled 7-2 that federal law preempts states from adding cancer warnings to pesticides that the EPA did not require, blocking state-level liability claims against Monsanto/Bayer for Roundup and potentially stalling thousands of lawsuits. The decision narrows state consumer-protection options, though lawmakers are moving to counter it with legislation or executive actions, and the ruling specifically concerns failure-to-warn claims rather than broader product-harm suits.
