Vijay wins floor test in Tamil Nadu: How governments prove majority inside Assembly, constitutional process explained

Tamil Nadu Chief Minister Vijay has won a floor test in the 234-member Assembly. His party, TVK, emerged as the single-largest party in the 2026 elections with 108 seats but fell short of the 118-seat majority mark, making coalition support necessary.

A floor test is a vote taken inside a Legislative Assembly to check whether the ruling government has the support of the majority of elected members. It is usually conducted when there is doubt about the government’s majority strength.



In Tamil Nadu, the Assembly has 234 seats. A simple majority requires at least 118 MLAs. This means a government must secure 118 or more votes in a floor test to prove it has the confidence of the House.

Constitutional basis of floor test

The Indian Constitution does not directly use the term “floor test”. However, it is derived from Articles 75 and 164, which say that the Council of Ministers is collectively responsible to the legislature.

This means the government can stay in power only as long as it enjoys majority support in the House.

A floor test is held inside the Assembly under the Speaker’s supervision. MLAs vote to show whether they support the government. Voting may take place through voice vote or division.

If the government secures majority support, it continues in office.

What happens if a floor test fails?

If a government fails to prove majority, the Chief Minister must resign. After this, the Governor may invite another party or coalition to form government if it can prove majority.

Governor of a State powers under Article 174 allow the Governor to summon, prorogue, and dissolve the State Assembly. Under Article 174(2)(b), the Governor acts on the advice of the Council of Ministers to dissolve the Assembly, but may apply judgment when the Chief Minister’s majority is in doubt.

If no alternative government can be formed, President’s Rule can be imposed under Article 356. In some cases, fresh elections may also be held.

A floor test ensures that a government continues in power only if it has majority support in the elected House. It is a key mechanism to maintain accountability in India’s parliamentary system.
