Why Judges breaks the nib of there pen after a death sentence

New Delhi: Why do judges break the nib of their pen in court room after giving a death sentence to a convict. 

This question has puzzled people for years.

But now several hypothesis were being put forwarded for this ritual that may us help solve this puzzle.

According to one theory, the judge breaks the nib of his pen because he doesn't want it to be used again for another judgment.

The very act of giving the death sentence, or taking the life of someone, is considered so “unholy” that the pen automatically becomes sullied.

Hence, the pen is destroyed.

Another theory being the pen is destroyed so that one one in his court, including himself, could question his verdict.

Once it's is pronounced it is considered final and no one can question it. Only a superior court has the power to override it.
