In Townsend v. Pierre, the New Jersey Supreme Court clarified that the net opinion rule bars expert testimony that contradicts uncontroverted factual evidence and further held that the use of hypothetical questions at trial cannot be used to salvage such an opinion. While the net opinion rule is usually formulated as “forbid[ding] the admission into evidence of an expert’s conclusions that are not supported by factual evidence or other data,” Polzo v. Cnty. of Essex, 196 N.J. 569, 583 (2008), the Court definitively stated that the rule also operates to bar expert testimony where the expert rejected as “mistaken” uncontroverted facts in evidence.
