Stage and bellwether status

The court continues to administer the confidential agreement for certain individual paraquat claims identified in CMO 24. June orders selected opt-out cases for limited discovery. The court canceled the September 15, 2026 hearing concerning attorney Mark DiCello’s cases in a September 11 order.

Settlement status

CMO 24 identifies a confidential Master Settlement Agreement executed September 3, 2025 for certain individual claims. The special master reviews qualification, eligibility and opt-out information. Public orders checked September 14, 2026 do not disclose a payout grid, settlement total or average individual award. A pending MDL action does not by itself establish settlement eligibility.
