The Supreme Court should grant the review of an appeals court decision that could block millions of surgery patients from needed relief, all based on the testimony of “experts” who themselves conducted no experiments, epidemiological studies, or lab work.

The background of the lawsuit at issue is bizarre. It involves a patient-warming system, called the Bair Hugger, which for more than three decades has been the industry standard for keeping people comfortable during surgeries. The suit against the Bair Hugger was filed — get this — by the very doctor who invented it.
