The Philippine Supreme Court is considered one of Asia’s most activist courts. During the regime of President Rodrigo Duterte (2016–22), however, concerns grew about its independence. This article investigates determinants of the Court’s behavior since the country’s return to democracy in 1987, with particular attention to “loyalty effects”—the likelihood that justices will vote for the government more often when the president who appointed them is in office. Drawing on a data set of seventy major political cases and sociobiographic profiles of the eighty-six justices who voted in them, we test for variables, including freshman effects and strategic defection toward the end of a presidential term. We find that early years on the bench are closely associated with a vote for the appointer’s administration, and the end of a presidential term is weakly associated with a vote against. Under the Duterte administration, voting preferences have been more aligned with the appointer, and factional alliances of justices appointed by different presidential administrations mirror political alignments. These results have practical implications for the fragile constitutional democracy in the Philippines and contribute to understanding of loyalty dynamics in less institutionalized judicial settings.

<title>Abstract</title>Since its inception in 1957, Malaysia’s Federal Court (FC) has often been embroiled in high-profile decisions that have dramatically shaped the rule of law and constitutional practice in Malaysia. Recent political change has renewed hope that the FC can reassert its early role as an independent and impartial arbiter of political conflict. This paper investigates determinants of the FC’s behaviour since 1960. It draws on a unique data set of 102 major political cases and socio-biographic profiles of the 73 judges who voted in these cases. After describing patterns of court decisions across time and judges, we test specifically for the impact on their decisions of the 1988 judicial crisis, length of time on the bench, the terms of successive prime ministers, and judges’ personal attributes, such as religion and ethnicity. Ethnicity, appointment after 1988, and the appointing prime minister proved to be closely associated with the direction of voting. We then position the results in the context of Malaysia’s evolving constitutional democracy and discuss their implications for students of comparative judicial politics.

The Constitutional Court of Indonesia is considered one of Asia’s most activist courts. Here we investigate empirically possible determinants of the decisions of its judges over the period 2003–18. The findings are based on a unique data set of 80 high-profile political cases, complemented by data on the socio-biographic profiles of 26 judges who served during that period. Testing for common perceptions of the Constitutional Court since its inception, we first describe patterns in judicial decision-making across time and court composition before testing specifically for the impact of the judges’ professional backgrounds, presidential administrations, the influence of the Chief Justice, and cohort behaviour. The analysis finds declining dissent among justices on the bench over time and also provides evidence of strategic behaviour of justices at the ending of their own terms. But there is little statistical evidence that judicial behaviour has been affected by work background (except for those coming from the executive branch), appointment track or generation – hence suggesting that justices seem to retain more independence than the public seems to perceive. We then discuss the results in the context of Indonesia’s evolving constitutional democracy and look at the implications for comparative studies of judicial behaviour.
