—In an action to recover damages for legal malpractice, the plaintiffs appeal from an order of the Supreme Court, Orange County (Peter C. Patsalos, J.), dated September 22, 1992, which denied their motion for partial summary judgment on their first cause of action.
Ordered that the order is affirmed, with costs.
In 1952 the plaintiffs purchased approximately 710 acres of
Fourteen years later, on October 7, 1974, the Town enacted a new zoning ordinance which expressly eliminated bungalow colonies as a permitted use. Thereafter, in June 1986 the plaintiffs, asserting a vested right to a nonconforming use of the entire 136 acres designated in the approved 1960 map as a bungalow colony, applied to the Town’s building inspector for a permit to construct an additional 419 bungalow units on their property. When the Town refused to issue the required permit, the plaintiffs retained the defendants to represent them. The defendants subsequently commenced a Federal civil rights suit on the plaintiffs’ behalf, alleging that the Town’s use of its zoning powers to deny the plaintiffs’ application for a building permit constituted a deprivation of property without due process in violation of 42 USC § 1983. Following a jury trial in the United States District Court for the Southern District of New York, the plaintiffs’ Federal civil rights claim was dismissed, but they were awarded judgment on an unpleaded pendent claim for a declaration that they had "a valid vested right to improve the bungalow colony by the construction of an additional 419 units” under State law. The United States Court of Appeals for the Second Circuit subsequently reversed the declaratory judgment in favor of the plaintiffs, however, concluding that the District Court had erred in exercising pendent jurisdiction over the State law component of the plaintiffs’ claim pursuant to 42 USC § 1983 because the plaintiffs’ complaint failed to separately plead a pendent State claim for declaratory relief.
The plaintiffs then commenced this legal malpractice action against the defendants, and thereafter moved for summary judgment on their first cause of action, contending that they would have obtained a declaratory judgment in their favor in the Federal suit but for the negligence of the defendants in failing to separately plead and label a pendent State claim for declaratory relief. In opposition to the motion, the defendants argued that, prior to the determination of the Second Circuit in the plaintiffs’ suit against the Town, controlling Federal
In order to obtain summary judgment on a legal malpractice claim, the movant must establish, through the submission of evidentiary proof in admissible form, that the attorney failed to exercise that degree of care, skill, and diligence commonly possessed and exercised by a member of the legal community (see, Logalbo v Plishkin, Rubano & Baum,
Guided by these principles, we agree with the Supreme Court that factual findings and expert testimony are necessary to determine whether the defendants’ conduct which is the subject of this case was negligent, or whether the defendants "made an honest mistake of judgment where the proper course of action was open to reasonable doubt” (Drab v Baum, supra, at 993). Pendent jurisdiction has been described as a "subtle and complex” area of the law (Aldinger v Howard,
