The collegium system has come under a fair amount of criticism. In 2015, the parliament passed a law to replace the collegium with a National Judicial Appointments Commission (NJAC). This was struck down as unconstitutional by the Supreme Court, in the Fourth Judges' Case, as the new system would undermine the independence of the judiciary. Putting the old system of the collegium back, the court invited suggestions, even from the general public, on how to improve the collegium system, broadly along the lines ofsetting up an eligibility criteria for appointments, a permanent secretariat to help the collegium sift through material on potential candidates, infusing more transparency into the selection process, grievance redressal and any other suggestion not in these four categories, like transfer of judges. This resulted in the court asking the government and the collegium to finalize the memorandum of procedure incorporating the above.
