The top court struck down the the 99th Constitutional amendment brought by the NDA government that would scrap the collegium system. It was a unanimous verdict by a five-judge constitution bench of the Supreme Court.
One of the contentious provisions of the new law was the inclusion of two eminent persons to the Commission which included the Chief Justice of India, two "senior most" judges of the apex court and the Union law minister.
The apex court has scheduled November 3 for further hearings on the issue of improving the collegium system of appointment of judges.
The petitions challenging the new legislation were filed by the group, the Supreme Court Advocates on Record Association, and others, who contended that the new law would hurt the independence of the judiciary.
The Centre had defended the introduction of the new law saying that the two-decade-old collegium system was not free from defects. It added that the Supreme Court Bar Association supported the new Commission. The creation of the Commission was also supported by 20 state governments which ratified the NJAC Act and the constitutional amendment.
