As salam o alaikum!
brother abbas we ll just have to fill in the specimen and hand it over to finance department they will send the forms to SP special branch located who will mark them to respective area's SHO who will further mark it to beat officer who would depute two constables to verify the details given by u in your performa. these constables will visit you, salute you, congratulate you and ahem ahem.
the process is not very lengthy as it seems on paper as soon as performas reach special branch they take 48 hours approximately to send it back to the requesting department if you have not been convicted or arrested in the past. if convicted or arrested then it might take 2 to 3 days extra.
dear brother asif, you are right it is more or less a formality as they just fulfill the requirements prescribed in establishment code (estacode) and government rules.
with best regards
