The lease of property for housing has always been problematic in Mexico City. Tenants and landlords, two opposing groups that need each other; have been in the past twenty five years, subjects of particular attention of the Mexico City and Federal Legislature. This paper analyze the Real Estate Leasing Controversies and we seek to demonstrate that they violate Articles 13, 14 and 16 of the Federal Constitution, because they would be privative, they would have been applied, between February 1985 and September 2009 - by special courts and would be used to submit a social class, as well as contrary to due process. They should be abrogated, and as that happens, be counteracted with the legal resources suggested here. [ABSTRACT FROM AUTHOR]
