Resignations
Section 306(2) · 1999 Constitution (2004 edition)
What Constitution says
(2) The resignation of any person from any office established by this Constitution shall take effect when the writing signifying the resignation is received by the authority or person to whom it is addressed or by any person authorised by that authority or person to receive it.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
