(1)  A free pardon extended by or on behalf of His Majesty shall have the effect of discharging the offender from all legal consequences of the offence for which such pardon is granted.

(2)  In any case in which a pardon imposes any conditions upon the person to whom it is granted, all courts of justice and officers shall give effect thereto in the same manner as they would be bound to give effect to the lawful sentence of a court imposing like conditions.
