Federal courts, state legislatures, and Congress are reshaping how mass torts and class actions work in 2026. Federal Rule of Civil Procedure 16.1, effective December 1, 2025, introduced the first-ever rule designed specifically for multidistrict litigation (MDL)—a framework allowing judges to manage large groups of linked cases more efficiently.
Alongside federal procedural changes, states are imposing new disclosure rules for litigation funding, tightening comparative fault standards, and raising or capping damages awards—shifting the legal landscape for plaintiffs, defendants, and settlements. These updates affect anyone involved in a pending mass tort: they change how cases are managed, what information must be disclosed, and how damages are calculated. This guide explains what changed, why it matters, and what it means for your case.

Federal Rules Now Address MDL Management Directly
For the first time, the Federal Rules of Civil Procedure include a dedicated rule for multidistrict litigation. FRCP 16.1, effective December 1, 2025, provides an optional early case management framework that lets judges set discovery timelines, establish bellwether trials, and structure settlement negotiations before cases sprawl across years. This rule does not require adoption, but judges can use it voluntarily to streamline the thousands of cases often consolidated into a single MDL.
The Judicial Panel on Multidistrict Litigation (JPML) also amended its procedural rules, effective February 19, 2026, following a public comment period that ended February 2, 2026. These amendments clarify when cases can be consolidated into an MDL and establish clearer criteria for transferring cases between districts. The practical result: cases may move to MDL faster, and judges have more tools to prevent delays.
Litigation Funding Now Must Be Disclosed Publicly
Third-party litigation funding—money investors provide to plaintiffs to cover costs while a case proceeds—is increasingly regulated. Multiple states including Georgia, Arizona, Colorado, Kansas, Montana, Oklahoma, and Tennessee enacted disclosure requirements for litigation funding agreements in 2025 and 2026, with Georgia requiring disclosure of agreements valued at $25,000 or more.
At the federal level, Senate Bill 3826—the Litigation Funding Transparency Act of 2026—was introduced to require public disclosure of third-party funding in class actions and MDLs involving 100 or more cases, and would prohibit funders from influencing settlement strategy or litigation decisions. This bill has not yet passed, but its introduction signals congressional interest in regulating litigation finance. The rules aim to prevent hidden conflicts of interest where funding agreements might push attorneys toward quick, low-value settlements rather than pursuing plaintiffs' best interests.
State Tort Reform Narrows Liability and Changes Damage Awards
State legislatures are rewriting comparative fault and damages rules in ways that can reduce payouts and narrow who can recover. In South Carolina, law H. 3430 (effective May 28, 2025) abolished joint and several liability for defendants found to be less than 50% at fault, meaning plaintiffs can no longer recover full damages from a defendant who bears minor responsibility for injury.
Louisiana's HB 431 adopts modified comparative fault that bars recovery entirely if a plaintiff is found 51% or more at fault. Non-economic damages (pain, suffering, loss of life enjoyment) are being capped by state law. Colorado increased its non-economic damages cap from $250,000 to $1.5 million effective January 1, 2025, with automatic 2-year inflation adjustments; medical malpractice caps will rise incrementally to $875,000 over five years. Georgia's tort Reform Act, signed April 22, 2025, included legislation funding registration requirements, restrictions on negligent security lawsuits, and new non-economic damages limits.
How These Changes Affect Pending Cases and Settlements
Procedural changes streamline case management but do not change who wins or loses. If you are in a pending MDL, FRCP 16.1 means your judge may adopt more structured discovery deadlines and earlier bellwether trials—tests of your case's strength before mass settlement. This transparency can speed resolution but also forces earlier commitments.

Litigation funding disclosure rules create a two-edged sword: they expose potential conflicts of interest, which may strengthen your negotiating position if a plaintiff's attorney is receiving pressure from a funder to settle quickly. However, increased scrutiny may make litigation funding harder to obtain for new claims. State tort reform narrowing liability or capping damages directly reduces the potential award in cases filed or pending in reformed states. If your case involves comparative fault (where both sides share responsibility), state changes like South Carolina's can mean smaller recoveries if the defendant is only moderately at fault.
Major MDLs and Bellwether Trials to Watch
Several major MDLs are advancing under the new rules and timeline. The hair relaxer MDL 3060 closed fact discovery March 18, 2026, with bellwether selections in April 2026; Meta social media addiction lawsuits had jury selection in May 2026; and Paragard IUD and GLP-1 vision-loss MDLs are advancing through critical discovery phases.
The PFAS water contamination MDL has grown to approximately 15,244 cases as of July 2026, with scope expanding beyond kidney cancer to include ulcerative colitis, thyroid disease, and immune disorders. These bellwether trials serve as test cases: the outcomes will signal settlement value and litigation risk for the thousands of remaining cases. If you are in one of these MDLs, pay attention to bellwether verdicts and settlement announcements—they typically anchor future negotiations.
Frequently Asked Questions
Does FRCP 16.1 apply to my case automatically?
No. The rule is optional and applies only if your judge and the parties agree to use it. Ask your attorney whether your MDL has adopted FRCP 16.1 case management.
If my case is in a state that just reformed comparative fault, does it apply to my pending claim?
Generally, yes. New tort reform laws typically apply to claims filed after the effective date. For pending claims, the rule in your state at the time of settlement may govern, depending on state law. Consult your attorney about your specific case.
Do I need to know about litigation funding if I am not receiving third-party funding?
You should know if your attorney's firm or the MDL administrator is receiving litigation funding, as disclosure laws now require that information be available. You have a right to ask about any funding that might influence settlement strategy.
How often do bellwether trials happen?
Typically once per MDL, though large MDLs may run multiple bellwether groups. Bellwether results are usually announced within weeks of verdicts, and follow the original bellwether—watch your MDL's court filings or attorney updates for dates.
