Judge Mannion of Middle District Addresses Scope of Permissible Expert Testimony At Trial

In the case of Dorshimer v. Zonar Systems, Inc., No. 3:13-CV-0553 (M.D. Pa. Aug. 8, 2016 Mannion, J.), Judge Malachy E. Mannion granted a Defendant’s Motion In Limine and ruled that a Plaintiff’s expert would not be permitted to offer opinions that an agency or contractual relationship existed between certain persons involved in the matter.

The court ruled that opinion testimony of these legal questions would not be helpful to the jury and, therefore, such testimony was not admissible under the Federal Rules of Evidence pertaining to expert testimony.   Judge Mannion also noted that there was no showing that  the engineering witness had any expertise in contract or agency law.

I send thanks to Attorney James M. Beck of the Philadelphia law firm of Reed Smith for bringing this case to my attention.
