28. The minority of a person duly admitted as a member of any society —
(a)
does not preclude that person from executing any instrument or giving a discharge necessary to be given under this Act or the Rules; and
(b)
is not a ground for invalidating or avoiding a contract entered into by any such person with the society,
and the contract entered into by that person with the society, whether as principal or as surety, is enforceable at law or against that person despite the person’s minority, except that this section does not apply to school co‑operatives.
