I think joint session can be called for approval but not sure. Anyway, if PDM's effort of work around via bill succeed then it will be precedent to curtail COAS power via bill as well. COAS's unquestionable powers have been proven lethal for country and institute itself, there should be option to challenge court martials in high and supreme courts, Other important things to do is to President and Prime Minister security should be independent, not in any way under influence of property dealers to ensure President and Prime Minister are safe from pole vaulters, same should be done with Rangers, FC, ANF and ISI. ISI should focus externally only just like professional agencies all over the world do instead of running p0rn industry, blackmailing and kidnapping own citizen.
