What is the significance of the phrase "by reason of his election" in determining whether a person is subject to disqualification under this Schedule?
The phrase "by reason of his election" in this context means that a person who has been elected to a certain office, such as the Speaker or Deputy Speaker of various legislative bodies, will not be disqualified under this Schedule if they voluntarily give up their membership in the political party they belonged to immediately before their election. They will also not be disqualified if they rejoin their original party after ceasing to hold the office. The phrase is significant because it establishes a condition under which elected officials can avoid disqualification due to defection or changing political affiliations during their term in that specific office.
