Today’s case is Bayes v. Biomet, (8th Cir., No. 21-2964, 9/21/2022), a lawsuit against the manufacturer of a failed metal-on-metal hip replacement.  The trial court instructed the jury on two theories of recovery:  strict liability and negligent design.  The outcome was unusual – at least, it seems unusual to me.  As the Eighth Circuit Court of Appeals explained,

Reading today’s case took me back to Boston University Law School and my first-year civil procedure course, which was taught by one of those professors who yell angrily at students who are unprepared to answer Socratic questions but are really nice guys outside the classroom.  (I say “guys” because there were maybe half a dozen female professors, yet women comprised at least a third of my class.  And when I argued cases in the Rhode Island and Massachusetts supreme courts and the First Circuit, there were no female judges on any of them.

This question was recently answered in the affirmative by California’s intermediate court of appeals in Bolger v. (4th App. Dist., Div. One, 8/13/2020),, and in the negative by the Ohio Supreme Court in Stiner v.

If that headline made you blink, don’t worry – you read it correctly, and it accurately states what happened.  The case is Markel v. Douglas Technologies Group, (8th Cir.

Rule 702 of the Minnesota Rules Evidence provides that “[an expert’s] opinion must have foundational reliability.”  This is the functional equivalent of Fed. R. Evid.

Last April I wrote about the FDA’s decision to ban the use of surgical mesh devices for transvaginal repair of pelvic organ prolapse (“transvaginal mesh” or “pelvic mesh”).  Of course, because transvaginal mesh was used for that purpose for 14 years (2002-2016), the resulting litigation isn’t over yet.  The most recent case to come to my attention is Kaiser v.
