Banerjee's communication to Law Minister Ravi Shankar Prasad came in response to a letter written by him to all Chief Ministers requesting them to ratify a constitutional amendment bill to make way for the proposed commission for appointment of judges to the higher judiciary.
Once the Commission is put in place, it will scrap the present collegium system under which judges appoint judges.
Seeking to bring clarity, the Law Ministry will soon write back to Banerjee pointing out that under the Constitution, the Governor takes decisions on the aid and advice of the Council of Ministers, sources said.
They said to ensure that the state governments have a say in appointment of the Chief Justice and judges of High Courts, the bill makes it clear that the views of the Chief Minister will be sought in writing.
While the Rajasthan Assembly has already ratified the bill, other states are likely to take up the exercise in October and November when their Assembly sessions commence, they said.
