The judiciary’s decisions increasingly made significant implications on Taiwan’ politics; the controversies of realpolitik have also resorted to judicial resolution all the time. Nevertheless, judges (as well as prosecutors, sometimes) are politically unaccountable in the name of “judicial independence” despite its great impact upon politics. Is it consistent with the principle of accountability, which is the integral part of democracy? This article indicates that law and judicial process are not absolutely independent and autonomous. Rather, judges always exercise great discretion in making various kinds of decisions with social importance. As long as the essence of judicial decisionmaking is both “choice” and “judgment”, judicial officials must be politically responsible for their processes and decisions. Judicial independence is not necessarily the opposite of democracy. At least, judges should assume the task of “reinforcement of the infrastructure of democracy”, and therefore consciously guarantee the preconditions of democracy in an active way. Thus, the activism of the Grant Justices and the ordinary courts has indeed promoted Taiwan’s democracy to a great extent; their effort in guaranteeing the equal citizenship of the marginalized groups, which is also one element of the infrastructure of democracy, is nonetheless far from enough.
