Subjective requirements of detention in Criminal Procedure Code Bill are not different from those currently in force. Lack of detailed and measurable requirements renders commissioner judges ineffective to solve detention problems. Absence of supervision and law enforcer’s moral degradation in single-judge hearings with final decision may incur abuse of power.Persyaratan subyektif penahanan dalam RUU KUHAP masih sama dengan KUHAP. Keberadaan hakim komisaris tidak efektif menyelesaikan permasalahan penahanan karena persyaratan subyektif penahanan yang belum rinci dan terukur. Degradasi moral penegak hukum, khususnya dalam pemeriksaan hakim tunggal dengan putusan bersifat final dan tanpa pengawasan berpotensi menimbulkan penyalahgunaan wewenang.
