Ony the best as judges....

Today's headline (The Sun):
Only the best judges move up

.....of course CJ is absolutely correct to select the best as judges.
The question is "what criterias"??

This is his criterias:

-- "their conduct, including in society, judicial temperament ... not to lose your temper every time you sit on the bench, fast in delivering written decision".

-- to be proactive, responsible, productive and prepared to sacrifice his/her own personal time for the purpose of justice and disposal of cases.

I am absolutely agree with CJ, but i have one question in mind.

How about the criterias like ability, experience and Intelligence to make the best judgement?? We are talking about MAKING JUDGEMENTS now, but processiong documents!!!
