Reflexiones sobre la naturaleza del derecho urbanístico y propuesta de definición

The issue of the Ninth (9th) Law of 1989 consolidated a novel discipline within the Colombian legal system: Urban Law. Since then, such discipline has been presented from different perspectives, either as set of public and private relationships, as general component of Public Law, as a specific discipline of Administrative Law, or even as a brand new discipline. This article considers Urban Law's nature, purposes, principles and its enforcement; it also deals with its placement within the legal sciences. Finally, according to the previously studied subjects, we present a proposal of Urban Law's definition.
