So far no Chief Justice of India has been impeached. In case of LokSabha 100 members should sign the motion. If it is Rajya Sabha 50 members sign. The speaker or the Chairman may admit or reject the motion.
If it gets admitted the Chairman or the Speaker must constitute a 3 member high-level committee to investigate into the charges or allegations made against the CJI.
A lawyer, a CJ from the High court and a CJ from the Supreme court should be on the committee to investigate against the CJI
If the charges are correct and have some scope against the CJI, then the house can take up the motion for further consideration into the matter.
Then the issue is taken up in the parliament or Rajyasabha and then it is put for voting and sent to the president for his approval. The President will also enquire and give his approval for the removal of CJI which is called as impeachment.
Here in the present case of Misra the CJI, the Vice President after due consultation with the legal luminaries have rejected the motion saying that there was no merit in the allegations made against the CJI.
