FAQ

How by-polls work and where these results come from.

What is a bye-election?

A bye-election (by-poll or upchunav) fills a single Lok Sabha or assembly seat that falls vacant between general elections, for example after a member dies, resigns or is disqualified, or wins two seats and gives one up.

How soon must a bye-election be held?

Section 151A of the Representation of the People Act, 1951 requires the Election Commission to fill a vacancy within six months, unless less than a year of the house's term is left or the Commission, with the Centre, certifies that it is difficult to hold the poll in that period.

How often do bye-elections change the party that holds the seat?

Of the 568 bye-elections here where we can compare with the previous general election, the seat went to a different party in 298 (52%). In the rest the party that won at the general election held it.

Where does this data come from?

From the Election Commission of India: the index cards and statistical reports it publishes for each bye-election. Seats are linked to today's constituency pages where the boundaries are the same; bye-elections held on older boundaries are listed without a link.

Source: Election Commission of India — bye-election statistical reports and digital index cards (eci.gov.in, old.eci.gov.in). “Held” or “gained” compares the bye-election winner with the winner of the same seat at the previous general election on our pages.
