The Delaware Supreme Court has revived medical negligence claims against a doctor and a women’s health clinic, finding a lower court judge improperly excluded expert testimony regarding a procedure gone wrong.

A three-judge panel of the high court ruled Tuesday that Superior Court Judge William L. Witham Jr. misinterpreted Delaware precedent for establishing the reliability of expert testimony, and ordered the judge to revisit a ruling that granted summary judgment in favor of All About Women and Dr. Christine W. Maynard, who practices gynecology for the Newark-based clinic.
