The PILs have been filed by former Additional Solicitor General Bishwajit Bhattacharya, advocates R K Kapoor and Manohar Lal Sharma.
The lawyers in their pleas submitted that 121st Constitutional Amendment Bill and The National Judicial Appointments Commission Bill, 2014, passed by Parliament is unconstitutional as it violates the basic structure of the Constitution.
"The Constitution itself recognises a clear demarcation separating the judiciary from the executive under Article 50 of the Constitution which is the underlying strength for a sound judicial system.
Bhattacharya also submitted that the Constitution empowers the Chief Justice of India to decide in every appointment of Supreme Court Judges and High court Judges and in every transfer of Judges from one High Court to another.

"This power is now being shifted to the NJAC and the very possibility of the CJI along with two senior-most Judges of SC being vetoed by the executive would be destructive of the independence of the judiciary and the doctrine of separation of power, both basic features of India's Constitution," he said.
The Lok Sabha had passed the the Appointments Commission bill with a crucial amendment suggested by opposition Congress that was accepted by the government.
