The New Jersey Supreme Court recently delivered a pivotal ruling that underscores the judiciary’s boundaries when handling complex medical evidence, particularly in cases involving Shaken Baby Syndrome (SBS). Emphasizing that judges are arbiters of law rather than experts in medical science, the Court clarified that while judges must assess the admissibility and relevance of SBS evidence, they should not attempt to weigh the scientific validity or interpret diagnostic findings themselves. This decision aims to safeguard the fairness of trials by ensuring that expert testimony remains the cornerstone of medical fact-finding in such sensitive and complicated cases.

In practical terms, the ruling instructs trial courts to focus on the following considerations when confronted with SBS evidence:

  • Qualification of experts: Verify that medical witnesses possess appropriate credentials and experience related to SBS.
  • Methodology scrutiny: Assess whether the scientific methods employed meet accepted standards within the medical community.
  • Clear boundaries: Avoid judicial commentary that implies medical expertise or casts doubt on recognized scientific consensus.
