IN A MEDICAL MALPRACTICE CASE, CONFLICTING EXPERT OPINIONS WHICH ARE EVIDENCE-BASED (I.E., NOT MERELY “CONCLUSORY”) REQUIRE DENIAL OF SUMMARY JUDGMENT (THIRD DEPT).

The Third Department, reversing Supreme Court in this medical malpractice case, determined plaintiff’s expert raised questions of fact about whether defendant surgeon failed to diagnose and treat a post-operative infection of plaintiff’s knee. Therefore, defendant’s motion for summary judgment should not have been granted. The decision is fact-specific and cannot be fairly summarized here. But the simple issue is: if experts on both sides of a med mal case come to conflicting conclusions which are evidence-based, summary judgment is inappropriate:

Based on the conflicting expert proof, plaintiff raised triable issues of fact … . Accordingly, defendants were not entitled to summary judgment. Kelly v Herzog, 2024 NY Slip Op 01137, Third Dept 2-29-24

Practice Point: In a med mal case, conflicting expert affidavits which are not “conclusory,” but rather are supported by evidence, preclude summary judgment.
