After receiving his degree , he worked with lawyer Majeed Memon for some months , before starting his career as a lawyer in 2003 . Soon started picking up cases of Muslims charged under the Prevention of Terrorism Act , 2002 ( POTA ) . Many of the cases were fought pro bono in consultation with NGOs , like '' Jamat-e-Ulema-e-Hind '' . His first major success as a defence lawyer came in the 2002 Ghatkopar bus bombing case , when Arif Paanwala , who was arrested under Prevention of Terrorism Act ( POTA ) and was named the prime accused , was acquitted along with eight others , due to lack of evidence , by the court ; this eventually led to the law being repealed
