appropriate at this stage. From the narration contained hereinabove with regard to the norms and guidelines prevailing in different High Courts, it is evident that varying periods of practice and different slabs of income have been, inter alia, prescribed as minimum conditions of eligibility for consideration for designation as a Senior Advocate. If merit and ability is to be the determining factor, in addition to standing in the Bar and expertise in any specialized field of law, we do not see why we should insist on any minimum income as a condition of eligibility. The income generated by a lawyer would depend on the field of his practice and it is possible that a lawyer doing pro bono work or who specializes in a particular field may generate a lower return of income than his counterpart who may be working in another field of law. Insistence on any particular income, therefore, may be a self-defeating exercise. Insofar as age is concerned, we are inclined to take the view that instead of having a minimum age with a provision of relaxation in an appropriate case it would be better to go by the norm of 10 years practice at the Bar which is also what is prescribed by Article 217 of the Constitution as a condition of eligibility for being considered for appointment as a Judge of the High Court.”
