dear,
there is no time frame prescribed for consideration of appeal against the order passed under disciplinary proceedings. however, it will be helpful for you to go through the relevant departmental instructions/ circulars and the rules under which your proceedings were conducted. here i would like to inform you that two punishments can not be imposed for the single offence. i.e either there should be reduction in pay scale or the dismissal. consult a good service matter lawyer near you . or you are free to contact me on tkg1968@rediffmail.com
best wishes.
