Committee hears supporters of updating Missouri class-action rule to match federal Rule 23

Representative Dane Diehl presented House Bill 534, explaining the bill would align Missouri’s state-class-action rule (identified in testimony as Rule 52.08) with the federal Rule 23 amendments adopted in 2018. Sponsors and supporting witnesses said the change is procedural — affecting certification and notice practice rather than underlying substantive law.

Supporters’ testimony Representatives of business and health-care groups told the committee that Missouri’s existing rule is outdated and creates inconsistent results compared with federal practice. Matt Price, general counsel for Diamond Pet Foods, described an ongoing case in which his company spent “millions of dollars” defending a class-action claim before securing decertification, and said earlier resolution on certification would have saved substantial costs. Dana Fries of the Missouri Hospital Association said rural hospitals have been targeted by out-of-state firms filing repetitive, cookie-cutter class claims and urged clarity and transparency for notice and attorney-fee procedures. Other supporters — including the Missouri Chamber, the Missouri Insurance Coalition and the American Tort Reform Association — also testified in favor.

What the bill would change Witnesses and the sponsor said HB 534 largely updates procedural steps: the timing of certification decisions, the standards for notice and opt-out opportunities, enhanced findings by courts when appointing class counsel and clearer attorney-fee disclosure. The intent, sponsors said, is to require courts to address certification early in litigation to reduce downstream expense and encourage fairer settlements.

What the record does not show The hearing did not produce formal opposition testimony on the record, and there was no recorded committee vote in the transcript. The transcript does not change substantive remedies or modify Missouri statutes beyond procedural rule text.

- "We are currently in the midst of an ongoing matter that launched our interest in this area of law... we are now several years and several millions of dollars of outside counsel spend before we were heard on our attempt to convince the court to decertify the case." — Matt Price, Diamond Pet Foods (testimony in favor) (transcript segment beginning s=7954.1553)
