Gloria Arroyo effectively declared martial law without calling it such under Proclamation No. 1017 today.
She just declared a “state of emergency” (see Constitution, art. XII, sec. 17 which deals with national emergency that confers extraordinary economic powers on the Chief Executive), which does not entitle her to call out the armed forces (art. VII, sec. 18).
Yet, I just heard her do exactly that—by leaving it to the military and police to take care of things.
As they say on Nickleodeon, “you can’t do that.”
