MALPRACTICE ACTION AGAINST A DOCTOR PROPERLY SEVERED FROM A NEGLIGENT HIRING AND RETENTION ACTION AGAINST THE DOCTOR’S EMPLOYER (SECOND DEPT).

The Second Department determined the action against a doctor (Wishner) for medical malpractice was properly severed from an action against the doctor’s employer (HMG) for negligent training, supervision, hiring and retention. Evidence the doctor had negligently treated another patient would not be admissible in the malpractice action but would be admissible in the action against the employer:

“In furtherance of convenience or to avoid prejudice the court may order a severance of claims, or may order a separate trial of any claim, or of any separate issue” (CPLR 603). Here, the Supreme Court providently exercised its discretion in granting that branch of Wishner’s motion which was to sever the causes of action asserted against HMG alleging negligent training, supervision, hiring, and retention from the causes of action premised on medical malpractice. In general, “it is improper to prove that a person did an act on a particular occasion by showing that he or she did a similar act on a different, unrelated occasion” … . Thus, generally, evidence of prior unrelated bad acts of negligent treatment of other patients, even if relevant, constitutes impermissible propensity evidence that lacks probative value and “has the potential to induce the jury to decide the case based on evidence of [a] defendant’s character” … . Mullen v Wishner, 2019 NY Slip Op 08850, Second Dept 12-11-19
