Second Department: Professional Reliability Exception Not Available Where Expert Witness Relies Upon Unobserved Or Non-Testified Third Party Report

In A-Tech Concrete Co., Inc. v Tilcon N.Y., Inc. (2009 NY Slip Op 01596) the Second Department examined the use of the professional reliability exception to the rule against hearsay in an appeal from a decision in a breach of contract proceeding in which the defendant was granted damages on counterclaim, and in which the expert witness attempted to rely on unobserved, third party expert findings.

At trial, the plaintiff sought to lead evidence in the form of an expert report, opinion evidence, and the report of a laboratory separate to that of the expert witness but on which the expert based his opinion evidence.

The expert witness sent materials to the laboratory for testing but did not oversee, attend, conduct or even observe the testing process. There was no evidence that the expert witness had personal knowledge of the testing process. Further, the expert witness did not testify about the testing procedure.

The defendant objected at trial to the admission of the laboratory report and the expert witness's opinion testimony and expert report based upon the prior report. The objection was sustained at trial and affirmed by the Second Department:

...the expert's testimony that reports such as the laboratory report are generally relied upon by professionals in his field did not sufficiently establish the reliability of the laboratory report for the purposes of the professional reliability exception (see Clevenger v Mitnick, 38 AD3d 586, 586-587; Wagman v Bradshaw, 292 AD2d at 89-90; Erosa v Rinaldi, 270 AD2d 384, 384-385). Thus, the Supreme Court properly sustained the defendant's objection to the [*2]admission of the laboratory report as well as the expert report and opinion testimony based upon the laboratory report.
