Finding Mexican federal law
The Diario Oficial de la Federación (DOF) is Mexico's official gazette. Federal laws, decrees, regulations, official standards (NOMs), the yearly tax rules and the minimum wage resolution only take effect once published there. The Chamber of Deputies keeps consolidated texts of federal laws in force, with the date of the last reform.
