“the persons recommended to the higher judiciary may be appointed only after a thorough objective assessment of their performance and integrity.” Critically examine the collegium system in this regard.
The Question is basically saying about the need to ensure the integrity of persons appointed to the higher judiciary. The Question is asking you to critically examine the collegium system in this regard.
Hence, You can focus on the failures happened with collegium system. Starting with Justice Ramaswamy, there are enough examples. After a judge retires allegations come up against him, including the ones before he was elevated, and it poses a question on the veracity of collegium system and shows the fallibility of the verification machinery. In spite of allegations and even being charge-sheeted by the inquiry committee, the persons are getting elevated on the technical ground that the resolution failed on the floor of the house.
(Lack of transparency in the judiciary is the only reason why people believe judiciary as the least corrupt institution because they are not having any clue what is happening inside.)
The answer should be able to give examples of the failure of collegium whereby wrong persons were elevated.
The Points written in your answer is good, but you could have included the demonstration of failures as I mentioned above.
(For Additional Information: This question was based on the comment by Collegium with regards to objections raised by the government about names of persons to be elevated to the high courts. Interestingly, collegium rejected the objections in the end. Read it Here.)
