The Council of Grand Justices released Constitutional Interpretation no. 656 on Oct. 16. Most of the justices agreed that combining former president Chen Shui-bian’s (陳水扁) cases and his long-term detention were constitutional. However, six of the justices voiced partly or wholly differing opinions. The biggest controversy was whether the Taipei District Court’s change of judges in Chen’s trial after the combining of the cases violated the principle of legally competent judges.
