First of all I am not a law student. Anyway I got interested in Indian Constitution and started reading Indian Constitutional laws.
I am quoting from "Indian Constitutional Law" by M P Jain 7th Edition, Page no. 39 under Decision on Disqualification
"When a person who has incurred a disqualification offers himself/herself as a candidate and is subsequently elected and if no one objects and if the Returning Officer accepts the nomination and if no election petition is filed challenging the election, then he/she would continue as a member in spite of the disqualification."
Does it mean that he can't be disqualified later by the same reason by which he had incurred a disqualification which was not considered during his election to a house?
