Rodriguez v. Wal-Mart Stores, Inc., 203 A.3d 114

Background

Rodriguez sued Wal-Mart after a falling clothing rack allegedly injured her arm; she later was diagnosed with Complex Regional Pain Syndrome (CRPS), a diagnosis of exclusion.
At trial, plaintiff testified to extensive prior medical and psychiatric history (childhood sexual abuse, suicide attempts, chronic abdominal surgeries, prior accidents).
Plaintiff’s experts diagnosed CRPS and rejected psychiatric causation; defense experts (neurologist and rheumatologist/internist) testified about somatization and symptom magnification, questioning the objective basis for her complaints.
Defense counsel sought to impeach causation by pointing to plaintiff’s prior medical/psychiatric history and by using terms like "somatization" and "symptom magnification."
Trial court allowed use of those terms after N.J.R.E. 104 hearings and admitted plaintiff’s prior medical and psychiatric history; jury returned a verdict for Wal‑Mart.
Appellate Division reversed, adopting a categorical ban on experts using terms that impugn credibility (e.g., equating symptom magnification with malingering) but upheld admission of prior medical history; New Jersey Supreme Court granted certification.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether medical experts may use terms like "somatization" and "symptom magnification" when testifying	Rodriguez: such terms are euphemisms for calling a plaintiff a liar and improperly invade the jury’s role in assessing credibility	Wal‑Mart: such terms are medically relevant and should be evaluated case‑by‑case under N.J.R.E. 401/403; jury can weigh credibility	Court: No categorical ban; admissibility is case‑specific under N.J.R.E. 401/403. Trial court did not abuse discretion admitting somatization and symptom magnification here.
Whether the term "malingering" should be categorically excluded when used by medical experts	Rodriguez/NJAJ: "malingering" inherently impugns credibility and risks undue prejudice	Wal‑Mart/NJDA: any exclusion should be governed by balancing rule, not per se ban	Court: Heightened concern about "malingering" but no per se rule; use must be scrutinized under N.J.R.E. 403 and reviewed for abuse of discretion.
Qualifications required for non‑psychiatrist experts to opine on somatization/symptom magnification	Rodriguez: non‑mental‑health experts (e.g., neurologists) lack appropriate qualifications to opine on these concepts	Wal‑Mart: overlap exists between neurology and psychiatry; non‑psychiatrists with relevant experience may opine; qualifications are for the trial court to assess	Court: Trial court did not abuse discretion in qualifying Dr. Mark (neurologist); generous approach to expert qualification and jury decides weight.
Admissibility of plaintiff’s prior medical and psychiatric history	Rodriguez: prior history was irrelevant or already ruled out by treating physicians; admission was unduly prejudicial	Wal‑Mart: prior history is relevant to causation, pre‑existing conditions, and damages; CRPS is diagnosis of exclusion so history is probative	Court: Admission was proper under N.J.R.E. 401/403; probative value not substantially outweighed by prejudice given CRPS diagnostic context.
