When a person who is convicted of an offence under section 6 holds any licence under any law for the time being in force in respect of any profession, trade, calling or employment in relation to which the offence is committed, the court trying the offence may without prejudice to any other penalty to which such person may be liable under that section, direct that the licence shall stand cancelled or be suspended for such period as the court may deem fit, and every order of the court so cancelling or suspending a licence shall have effect as if it had been passed by the authority competent to cancel or suspend the licence under any such law.
     Explanation.--In this section, "licence" includes a permit or a permission.
