The rule that government may not condition the approval of a land-use permit on the owner's relinquishment of a portion of his property, unless there is a nexus and rough proportionality between the government's demand and the effects of the proposed land use, applies even when the permit is denied because the applicant refuses to so relinquish or to pay a monetary exaction.
