An increasingly common practice in Israel and other countries is the imposition of restrictions and burdens on land developers, without utilizing formal planning or expropriation processes. A land owner, for instance, may agree to dedicate part of his land for public use and to transfer its title to the planning authority, with no compensation and without expropriation procedures. Similarly, the parties can agree on height or bulk restrictions for buildings to be constructed on the land, beyond those imposed by the plans applicable to the area. The burdens might take the form of a contract between the planning authority and the developer, or may be included in the building or subdivision permits. In many cases, the authority attempts to use these tools to obtain benefits that it could not have acquired through its statutory powers. This article examines the legality of this practice and the restrictions which should be imposed on it. As regards the transfer of rights in land without compensation, the question arises whether such agreements or permits should be subjected to the same restrictions that apply to injuries caused by plans and expropriations. For instance, should one invalidate an agreement in which a developer purports to transfer land without compensation in quantities beyond that permitted by statutes authorizing expropriation without compensation? Does the fact that the land was transferred with the owner's consent (and not through the coercive power of expropriation statutes) restrict judicial intervention to contract law grounds, such as duress, misrepresentation or mistake?
