This Article examines the ad hoc, multifactor, regulatory takings doctrine derived from Penn Central Transportation Co. v. City of New York. It analyzes the conventional three-factor characterization of the Penn Central factors, and concludes that a four-factor approach better captures the dynamics of the Penn Central analysis. "Parcel as a whole," conceptually regarded as delimiting the relevant parcel for the Penn Central inquiry, in fact interacts with the "economic impact," "investment-backed expectations," and "character of the regulation" factors. While the four-factor analysis advocated here is conceptually better and enhances an understanding of how Penn Central operates, the doctrine remains under-theorized, subjective, with its factors mutually referential, and unable to provide a reliable guide to courts or litigants.
