It’s hard to think of any recent litigation where plaintiffs didn’t seek overblown discovery about adverse event reports and then have their experts rely on those reports in an effort to establish causation.  But as we’ve blogged about repeatedly, reports from the FDA’s Adverse Event Reporting System (“FAERS”) do not establish causation (and, for good measure, they don’t constitute newly acquired information). Today’s decision, Taylor v. Dixon, 2026 WL 865183 (M.D. Fla. Mar. 30, 2026), is a little different since it involves a federal habeas petition.  But we couldn’t resist blogging about it given the court’s comprehensive take-down of the attempted use of an adverse event report to show causation.
