You should look up these subjects properly and pause to think for a moment before making these reactionary statements. I’ve advised you this in the past.
At present the appointment of judges is far too discretionary. Forget the politics for a second, the last six appointments have been made with passing over senior judges. In Sindh, three times now the three most senior have been passed up. And the CJP has just tried to appoint 4th, 6th and 7th ranking judges.
Provincial Bar associations, SCBA and PBC have all called this out. Even if seniority is not an absolute guidance, it should not be ignored. Other considerations such as merit are subjective and hard to measure, but even here CJs have historically practised discretion.
Several resolutions have been adopted by the Bar asking legislators to work on codifying and writing into law a proper mode of deciding who should be appointed, whether that’s merit, seniority, it needs to be defined.
