Sanjay, a resident of Sonepat ditrict, married his girlfriend Mamta following a special three-hour permission given by court.
The marriage ceremony, that took place at the park inside the court campus, was attended by family members from both sides, besides a number of lawyers and court employees.
In December last year, the girl, through Sanjay's counsel, had moved a petition before the court requesting permission for marriage.
The court had permitted to conduct the marriage ceremony at its premises after police, citing security reasons, had turned down the request.
Sanjay, convicted in June last year in a 2010 triple murder case, was taken back to jail after marriage, while the bride went with her in-laws.
