Hello

According to the Indian nursing council act 1947

Term of office and casual vacancies.

(1) Subject to the provisions of this section, an elected or nominated member, other

than a nominated President, shall hold office for a term of five years from the date of

his election or nomination or until his successor has been duly elected or nominated,

whichever is longer.

(2) An elected or nominated member may at any time resign his membership by

writing under his hand addressed to the President, and the seat of such member

shall thereupon become vacant.

(3) An elected or nominated member shall be deemed to have vacated his seat if he

is absent without excuse sufficient in the

opinion of the Council from three consecutive meetings of the Council where the

interval between the first and third of the said meetings exceeds six months.

(4) A casual vacancy in the Council shall be filled by fresh election or nomination, as

the case may be, and the person elected or

nominated to fill the vacancy shall hold office only for the remainder of the term for

which the member whose place he takes was elected or nominated.

(5) Members of the Council shall be eligible for re-election or renomination.

Hope this helps!!!
