RAWALPINDI Lahore High Court (LHC) Rawalpindi Bench on Tuesday issued notice to Chairman Senate of Pakistan while hearing a petition moved by an Additional Secretary challenging the reversal of his appointment orders from regular to ad-hoc bases. Justice Sheikh Rauf Ahmed issued the notice to the Chairman Senate and sought his written comments on the petition filed by Ghulam Muhammad Chaudhry. G M Chaudhry moved the court through his lawyer Syed Hasnain Kazmi and made Senate chairman as respondent. In his petition, he maintained before the court that under the law the Chairman has not authority to amend the terms and conditions of his appointment. He stated that he had been serving in Federal Ministry of Law and Justice as Legislative Advisor in pay scale MP-II equalling to BPS-21 before he was appointed as Additional Secretary in Senate on May 2 last year. The petitioner has said that it was on February 16, 2010 the Chairman in a Senate secretariat memorandum suppressed the earlier notification of his appointment and turned the nature of his job into ad-hoc basis till the appointment of a regular Additional Secretary after proper advertisement. The petitioner has maintained that he was invited to the post and he only accepted it on the terms and conditions offered to him in the letter of April 25 2009 but the Chairman had changed the nature of job using his discretion without lawful authority. He beseeched the court to declare the orders of the Senate memorandum of February 16 2010 as illegal and without any lawful affect.
