The chief justice said if in any matter the constitution and law are not clear then the convention would prevail. However, Justice Asif Saeed Khan Khosa raised a question if there were 10 additional judges and out of them five were made permanent this year and other five next year then what would be the criteria for seniority.Justice Anwar Zaheer Jamali remarked that when the President makes a judge permanent then the date a notification for the purpose is issued would be considered the seniority. The bench said that Sindh High Court had declared that a judge’s seniority starts from the date when he is made permanent.The petitioner’s counsel Zaka-ur-Rehman argued that in the judges’ pension case the apex court had ruled that there was no difference between the additional and the permanent judges. He pleaded that the present seniority committee composition is against the constitution and also the verdicts of the courts.He said that the additional judges were appointed according to the Article 193, 197, 18th and 19th Amendments.
