More than 100,000 claims against Monsanto could be blocked if the Supreme court finds in favor of Bayer's appeal,
"there are over 100,000 active claims across the country alleging that glyphosate in Roundup caused non-Hodgkin lymphoma. The U.S. Supreme Court heard oral argument in the leading case, Monsanto Company v. Durnell, No. 24-1068, on April 27, 2026. Separately, a $7.25 billion proposed class settlement is pending final approval in Missouri state court." - AllAboutLawyer
As noted above, the oral arguments are complete. The Supreme court ruling for Monsanto Company v. Durnell, No. 24-1068 may arrive as early as July 6. Meanwhile, there is very little time to make your voice heard regarding the recusal of former Monsanto lawyer and lobbyist, Clarence Thomas.

Monsanto is facing a U.S. Supreme Court ruling that could decide whether more than 100,000 Americans who developed non-Hodgkin lymphoma after using Roundup weedkiller can continue pursuing their toxic exposure lawsuits in state court. The case, Monsanto Company v. Durnell, No. 24-1068, was argued before the Supreme Court on April 27, 2026, and a decision is expected by early July. At the same time, Monsanto’s parent company Bayer AG has proposed a separate $7.25 billion class action settlement that is already moving through Missouri state court — with an opt-out deadline of June 4, 2026, weeks before the Supreme Court is expected to rule.
