Daniel E. Cummins, Esquire, an insurance defense attorney with the Scranton law firm of Foley, Cognetti, Comerford, Cimini & Cummins has authored the following amicus curiae brief on the behalf of the Pennsylvania Defense Institute. The issue presented is whether the trial court properly ruled, within its broad discretion, that repeated communications from plaintiffs' attorney to the Plaintiff's treating physician/medical expert witness for trial were discoverable by the defense where the letters and e-mails to the expert purposefully addressed how the expert should frame his opinion testimony and where the trial court found, after an in camera inspection of the documents, that such written communications by the Plaintiffs' attorney may have materially impacted the expert's formulation of his opinion.
