Prerogative of mercy
Section 212(1) · 1999 Constitution (2004 edition)
What Constitution says
(1) The Governor may - (a) Grant any person concerned with or convicted of any offence created by any law of a state a pardon, either free or subject to lawful conditions; (b) grant to any person a respite, of the execution of any punishment imposed on that person for such an offence; (c) substitute a less severe form of punishment for any person for such an offence; or (d) remit the whole or any part of punishment for any punishment imposed on that person for such any offence or of any penalty forfeiture otherwise due to the state on account of such an offence.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
