Paraquat Parkinson's Lawsuit in Michigan

What Michigan residents should know

Michigan residents are not necessarily limited to filing only in Michigan state court. Many mass tort claims may be evaluated by national firms, filed in federal court, coordinated through MDL proceedings, or handled through another legal process.

State law may still matter for deadlines, damages, claim evaluation, and certain procedural issues.

What stands out about Paraquat litigation in Michigan?

Michigan combines diverse paraquat-relevant agriculture with documented applicator-training infrastructure. Michigan is a major soybean state (about 2.3 million planted acres per USDA NASS 2018), the country's leading sugarbeet state, and grows specialty crops where paraquat may be used. Michigan State University Extension has published label-mandated training materials specifically for paraquat applicators in Michigan.

Federal paraquat cases filed by Michigan residents in the Eastern or Western District of Michigan are transferred by the JPML into MDL-3004 (S.D. Illinois, Chief Judge Nancy J. Rosenstengel) for coordinated pretrial proceedings.

Restricted-use pesticide applicators are governed by Michigan Administrative Code rules administered by the Michigan Department of Agriculture and Rural Development (MDARD). As of mid-2026, a review of Michigan Attorney General announcements did not surface a completed state-level paraquat action against Syngenta or Chevron; the CSG Midwest 2026 legislative tracker indicates paraquat-related bills had been introduced in Michigan during the 2025–2026 biennium but had not passed as of late March 2026. Michigan's personal injury statute of limitations is generally three years (Mich. Comp. Laws § 600.5805(2)).

What is the filing deadline for Paraquat lawsuits in Michigan?

For a Michigan resident researching Paraquat claims, the starting point is usually Michigan's general personal injury period: 3 years under Mich. Comp. Laws § 600.5805(2). That is only a starting point, not a final legal deadline for every person.

The real filing deadline can depend on diagnosis date, when the injury and possible cause were discovered, exposure location, wrongful-death issues, prior claim paperwork, and whether the case is filed directly, transferred to an MDL, or handled through another process.

Discovery-rule note: Michigan applies limited discovery-based accrual rules; latent-injury treatment varies by claim type.

How long do Michigan residents have to file?

Michigan's personal injury statute of limitations applicable to product liability claims is 3 years (Mich. Comp. Laws § 600.5805(2)). Accrual timing, tolling, and repose periods can still change the real deadline in an individual case.

• Filing period: 3 years — Mich. Comp. Laws § 600.5805(2).
• Discovery rule: Michigan applies limited discovery-based accrual rules; latent-injury treatment varies by claim type.

Because the controlling deadline depends on diagnosis date, discovery facts, exposure history, wrongful-death rules, and how the claim is filed, only a licensed attorney can confirm the deadline that applies to a specific situation. This page is general legal information, not legal advice.

What should Michigan residents ask a lawyer?

• What proof do you need to connect my farm, applicator, or bystander exposure specifically to paraquat?
• How do Parkinson's diagnosis date, symptom history, and neurology records affect review?
• Does the confidential settlement program affect whether my claim can be evaluated?
• How do state filing deadlines affect my exposure and diagnosis timeline?
• Would my claim be handled locally, nationally, or through the MDL?
• Are there upfront costs?
