Freedom of information is a public freedom stated in art 20.d of th Spanish Constitution of 1978 with the highest standards of judicial proteccion as being included in the ” super-guaranteed” seccion primera, capítulo segundo, titulo primero .
It has not been a development of this in an specific act so far but there are plenty of COnstitutional Court´s decissions regaridng this: this Tribunal is the author of the definitions, characterisitcs, features, types of FUndamental Rights and Public Liberties in Spain.
I love Constitutional Law! Actually doing my PHD on COnstitutional Law.
