What are the consequences if it is later discovered that an individual who was not entitled to vote or sit in the Parliament participated in its proceedings according to the Indian Constitution?
There are no direct consequences mentioned in the context provided from the Indian Constitution. However, it is stated that the proceedings in Parliament shall be valid notwithstanding that it is discovered subsequently that some person who was not entitled so to do sat or voted or otherwise took part in the proceedings. This implies that such an individual's participation does not render the proceedings invalid.
