El ejercicio de la potestad legislativa delegada al presidente de la repÁblica entre los aÑos 1833 y 2014

This article reviews the exercise of legislative power delegated from the 1833 Constitution to the present. In the XIX century its use responds to broad authorizations from Congress, which include Congressional Legislative Power. In the XX century, rules of legislative force and effect were born as practice praeter constitutionem in 1927 and continue to operate as broad authorizations to regulate with the status of law and not as precise mandate. Its main initial use between 1927 and 1932 (control of public expenditure and reorganization of the public administration) is maintained throughout the past century. Its incorporation to the Constitution in 1970 and then to that of 1980, tries to reinforce its commission character. However, in practice, the delegation continues to function as an authorization to regulate matters of administrative organization with legislative force and effect.
