Sections 6 and 7 of CA No. 141 provide that it is only the President, upon the recommendation of the proper department head, who has the authority to classify the lands of the public domain into alienable or disposable, timber and mineral lands.
In issuing Proclamation No. 1064, President Gloria Macapagal-Arroyo merely exercised the authority granted to her to classify lands of the public domain, presumably subject to existing vested rights. Classification of public lands is the exclusive prerogative of the Executive Department, through the Office of the President. Courts have no authority to do so. Absent such classification, the land remains unclassified until released and rendered open to disposition
