The Supreme Court today refused to entertain a PIL seeking to raise the retirement age of its judges. A bench headed by Chief Justice T S Thakur referred to constitutional provisions on the issue. It said the retirement age of Supreme Court judges has been settled by the Constitution itself and it cannot be looked into.<br/><br/>The plea was filed by a Law Student. It sought from the bench a direction to the Centre over setting up an authority to consider increasing retirement age of the apex court judges. Theses judges presently retire at the age of 65.
