This paper extends the empirical analysis on the determinants of judicial behaviour by measuring the ideal points for the Justices of the Philippine Supreme Court for 1986−2010. The Philippines is an interesting case given the US influence in designing the Supreme Court while the political and social context differs significantly. The estimated ideal points allow us to focus on political coalitions based on presidential appointments. We find strong evidence to support the existence of such coalitions along a government-opposition policy space. Implications for comparative judicial politics are discussed.
