The Supreme Court on Wednesday termed the changes made by the Kerala High Court as "manifestly arbitrary" in the criteria for selection of additional district judges (ADJs) in the state in 2017. A five-judge constitution bench headed by Chief Justice D Y Chandrachud, however, refused to "unseat" those who were selected for the state higher judicial services six years ago, observing such a step will be against "public interest" and "harsh" on them.
