Good idea! But since you know him personally why don't you ask him why did he do that!!? I would like to quote you the reference of FIA inquiry that confirms this in detail, but I am sure your personal acquaintance would have managed to obtain a copy of it already.
Here is the answer to your sarcasm: Usually people dishonorable and wicked by nature do not need particular reasons to commit such mean and naive treacheries, abominations keep occurring by them just unwittingly. It is in their nature to lie and deceive even when there is no substantial gain from it. This is the reason your acquaintance submitted three different Dates of Birth: which is a crime. All other accusations are also correct and documented against with proofs by FIA. Akhtar Rana in unsuitable for AGP; what more: he is also unsuitable for being even a clerk in the government. He has been exonerated and made AGP with the sole purpose of delivering the ruling party against corruption inquiries.

Let's just wait, if something turns out about him from the Court.

The loophole in Pakistan's civil service is that seniority is considered in exclusion to performance evaluation for promotions (see this: All is not well | Opinion | DAWN.COM). And once selected, every maja gama would become entitled to BPS-22 near the end of his career if he has a benefactor in the government. This is what is happening with Rana.

A person fallen to such depravity and dishonesty that he cannot disclose something as basic as his Date of Birth to his employer without lying DOES deserve to hold others accountable, definitely!! This is exactly the reason Pakistan is among the most marvelous, prosperous, and just countries in the world.
