Summary
Results of five Assembly by-elections declared on 9 October 2026 gave the ruling party in each State or Union Territory a clean sweep. The BJP won Nandigram and Rejinagar in West Bengal and the AINRC won Thattanchavady in Puducherry.
In Tamil Nadu, the ruling TVK won Dharapuram and Madurantakam with candidates who had won those seats for the AIADMK in May, resigned, joined the TVK and been renominated. They won with 37% and 40% of the vote, about eight points ahead of the DMK, while the AIADMK came third.
The TVK's tally rose to 109 in the 234-member House and four more AIADMK MLAs have since joined it. TAN argues that this resign-and-recontest route defeats the purpose of the anti-defection law and that the law should close it even though voters are rewarding it.
WHY IT MATTERS FOR UPSC & STATE PCS
In the October 2026 bypolls, MLAs who had resigned from the AIADMK and joined the ruling TVK in Tamil Nadu were re-elected on the TVK's ticket. With more vacancies pending from further AIADMK resignations, the debate over whether the Tenth Schedule can stop resign-and-recontest defections has returned.

The Loophole Voters Keep Rewarding
The tension The anti-defection law was written to stop legislators from switching sides for office.
A newer route avoids it entirely: resign the seat, join the ruling party and win it back. When voters re-elect such a candidate, two democratic principles collide. One is that legislators should be bound to the mandate they were elected on. The other is that voters have the final word.
The case for closing the loophole The Tenth Schedule, added in 1985, disqualifies a legislator who voluntarily gives up party membership or defies the party whip.
Resignation under Article 190 is a different path, valid if it is voluntary and genuine. The two together create a gap. A legislator who resigns before defecting is not disqualified under the Tenth Schedule. They simply leave, join the ruling side and stand again.
The Supreme Court widened this route in Shrimanth Balasaheb Patil (2019). It upheld the disqualification of Karnataka's rebel MLAs but held that the Speaker could not bar them from contesting the resulting by-elections. Several were re-elected that December on the ruling party's ticket.
Tamil Nadu shows the pattern now. Two AIADMK MLAs elected in May resigned, joined the TVK and won back Dharapuram and Madurantakam in October. Four more AIADMK MLAs have since joined the TVK and their seats too will go to by-elections.
Each instance turns a minority-government arithmetic problem into a manageable recruitment exercise. The Law Commission saw this coming. Its 170th Report in 1999 recommended barring defectors from holding office and from contesting for the remainder of the Assembly's term.
The 91st Amendment of 2003 adopted only a weaker version. It barred disqualified members from remunerative political posts until re-elected, which sets no barrier at all against re-election.
The case for letting voters decide The counter-argument is strong.
A by-election is not a technicality. Voters in Dharapuram and Madurantakam knew exactly who was standing and why and they chose them again. If the law bars such candidates for the rest of the term, it overrides the electorate's present judgment in the name of its past one.
Voters may have good reasons to prefer a representative aligned with the government, since by-elections tend to favour the party in power because voters want access to administration. A bar would also be blunt. It would catch the opportunist and the legislator who leaves a party on genuine principle alike.
TAN's position TAN's position is that the law should close the loophole, by barring those who resign mid-term from contesting by-elections in that term.
Voters' choice in a by-election is real but structurally tilted. It is made after the defection has already changed the balance of power and with the government's resources behind the candidate. The original mandate, given in a general election with full competition, deserves stronger protection than a by-election held on the defector's terms.
A legislator who leaves on principle is not silenced. They can sit out the term or contest again at the next general election.
