Have just began reading the decision. By just reading the statement of facts you would know how the Court had decided. This, for me, is the deciding point:

During the oral arguments held on March 7, 2006, the Solicitor General specified the facts leading to the suance of PP 1017 and G.O. No. 5. Significantly, there was no refutation from petitioners’ counsels. (Emphasis made by the Court)

And thus, the Court says:

Petitioners failed to show that President Arroyo’s exercise of the calling-out power, by issuing PP 1017, is totally bereft of factual basis. A reading of the Solicitor General’s Consolidated Comment and Memorandum shows a detailed narration of the events leading to the issuance of PP 1017, with supporting reports forming part of the records. Mentioned are the escape of the Magdalo Group, their audacious threat of the Magdalo D-Day, the defections in the military, particularly in the Philippine Marines, and the reproving statements from the communist leaders. There was also the Minutes of the Intelligence Report and Security Group of the Philippine Army showing the growing alliance between the NPA and the military. Petitioners presented nothing to refute such events. Thus, absent any contrary allegations, the Court is convinced that the President was justified in issuing PP 1017 calling for military aid.

The SC has decided that Proc. 1017 was constitutional pertaining to its provisions calling on the police and the military to prevent or suppress violence. Parts of the said proclamation calling on the military to enforce laws not related to lawless violence as well as decrees promulgated by the President are deemed unconstitutional.

WHEREFORE, the Petitions are partly granted. The Court rules that PP 1017 is CONSTITUTIONAL insofar as it constitutes a call by President Gloria Macapagal-Arroyo on the AFP to prevent or suppress lawless violence. However, the provisions of PP 1017 commanding the AFP to enforce laws not related to lawless violence, as well as decrees promulgated by the President, are declared UNCONSTITUTIONAL. In addition, the provision in PP 1017 declaring national emergency under Section 17, Article VII of the Constitution is CONSTITUTIONAL, but such declaration does not authorize the President to take over privately-owned public utility or business affected with public interest without prior legislation.

G.O. No. 5 is CONSTITUTIONAL since it provides a standard by which the AFP and the PNP should implement PP 1017, i.e. whatever is “necessary and appropriate actions and measures to suppress and prevent acts of lawless violence.” Considering that “acts of terrorism” have not yet been defined and made punishable by the Legislature, such portion of G.O. No. 5 is declared UNCONSTITUTIONAL.

The warrantless arrest of Randolf S. David and Ronald Llamas; the dispersal and warrantless arrest of the KMU and NAFLU-KMU members during their rallies, in the absence of proof that these petitioners were committing acts constituting lawless violence, invasion or rebellion and violating BP 880; the imposition of standards on media or any form of prior restraint on the press, as well as the warrantless search of the Tribune offices and whimsical seizure of its articles for publication and other materials, are declared UNCONSTITUTIONAL.

As usual, the decision ended with partial granting of petitions, as the Court did with the other issues. Solomonic? Yeah. Arroyo et al getting a slap in the wrists – using marshmallow sticks.
