The section says a member is not entitled to vote in case he has not fully paid the value of shares or lien has been created in the shares. e.g. A has 10 shares of Rs 10 each. For these 19 shares he has partly paid 5 Rs and rest 5Rs are unpaid. then such member shall not be entitled to excercise his voting right on the 10 shares.
