On 6 March, President Arroyo signed into law the Human Security Act of 2007, a new anti-terrorism law passed by Congress at a special session in February. On 13 March, Martin Scheinin, UN Human Rights Council expert on counter-terrorism and human rights, expressed concern about the Act for, among other reasons, its broad definition of terrorist acts, insufficient procedural guarantees regarding pre-charge detention and the low evidentiary threshold for the imposition of house arrest on terrorist suspects. Martin Scheinin encouraged the Parliament to amend the legislation at its next regular session.
