Unconstitutional veto players are not completely absent in the political system of the Philippines. In 2006, there was an alleged coup attempt.
Before President Aquino was elected in 2010, former president Gloria Macagapal-Arroyo successfully installed some of her closest allies in key government positions such as the judiciary, military and police forces and the executive branch. This had been rather challenging to the new administration as these actors had the power to block decisions of the present government, until the successful impeachment of the Arroyo-appointed Chief Justice Renato Corona in May 2012.
Nevertheless, the overall situation can be judged as relatively stable as for now, hence positioning the Philippines at mid-range within this section.
