AC44320 - Gianetti v. Neigher (This appeal arises out of a legal malpractice action brought by the plaintiff, Charles D. Gianetti, against the defendant, Alan Neigher, an attorney who represented the plaintiff in a prior civil action (prior action) against Norwalk Hospital (hospital). The plaintiff appeals from the summary judgment rendered by the trial court in favor of the defendant. On appeal, the plaintiff claims that the court improperly granted the defendant’s motion to preclude the testimony of the plaintiff’s expert witness, Attorney Bruce H. Stanger, because (1) the sanction of precluding the testimony was not proportional to the plaintiff’s noncompliance with the expert disclosure requirements set forth in Practice Book § 13-4, which the plaintiff contends could have been adequately remedied by a less severe sanction, and (2) in so sanctioning the plaintiff, the court improperly determined that the expert’s opinion was not supported by a sufficient factual basis. The plaintiff additionally claims that the court improperly rendered summary judgment because (1) the court failed to consider the testimony of his expert witness, and (2) even if the court properly precluded the testimony of his expert witness, a genuine issue of material fact nonetheless existed as to the legal malpractice elements of causation and damages. We affirm the judgment of the court.)
