Are you saying he sought admission in Quetta colleges at age of around 30? While he joined the Bar in 1974 after completing his LLB, he was advocate of High Court in 1976 (more than 30 years ago).
Maybe he started practicing law before he got his law degree & also got fake birth certificate and caught unicorn too. Or maybe he got his law degree from online...oh wait there was no internet back then? That ex Cj is a clear son of gun :D
