18. Demonetisation of currency notes and coins

The Authority may, by notification in the Gazette, withdraw any particular issue or denomination of currency notes and coins issued by the Authority which upon such withdrawal cease to be legal tender.

Any such notification must give holders of the currency notes and coins to be withdrawn a reasonable period, in any event at least 6 months, within which such notes or coins may be exchanged at their face value for other legal tender issued by the Authority.
