The public trust doctrine provides that government holds title to certain lands and waterways in trust for the public benefit and public use.1  While the common law doctrine varies from state to state, historically it “requires that . . . trust land[s] be accessible and used for a public purpose; that [they] be put to . . . uses appropriate to the resource; and, in some cases, that [they] not be sold.”2  It does not, however, foreclose the private lease and license of public lands; rather, it requires that such lands be utilized primarily for the public benefit, and only incidentally for private benefit.3  Thus, fundamentally, the public trust doctrine incorporates a public use test.

The New York public trust doctrine, as it applies to public parkland, has nebulously defined “public benefit” and “public use” as a “park,” in contrast to a “non-park,” use.4  In this Comment, I argue for a reformulation of the public trust doctrine in New York in consonance with the historical public use test, as defined by the United States Supreme Court most recently in Kelo v. City of New London5 and New York state courts more than three decades ago in Yonkers Community Development Agency v. Morris.6  Focusing specifically on New York City parks, I argue that a reformulated public trust doctrine will permit optimal public benefit from privatization of some green spaces.  This public benefit will come in the form of revitalized green spaces, previously forsaken by municipal government.  Further, a reformulated public trust doctrine will limit judicial intervention in this area to the courts’ traditional role of striking down transactions in which government overreaches and attempts to transfer trust lands predominantly, not incidentally, for the benefit of private third parties. 7 [ Read More ]

REV. 471, 495-96 (1970) (describing the courts’ role as forcing the legislature to expressly transfer trust lands to private third parties where such transfers appear to subordinate the public interest).  Sax argues that the courts, in forcing government to expressly authorize questionable transfers to private parties, create “an openness and visibility which is the public’s principal protection against overreaching, but which is often absent in the routine political process.”  Id. at 496.
