Why in News C. Joseph Vijay – founder of the Tamilaga Vettri Kazhagam (TVK) – was sworn in as Chief Minister of Tamil Nadu on May 10, 2026, along with nine ministers, by Governor R. V. Arlekar at the Nehru Indoor Stadium, Chennai. The Governor directed a vote of confidence on or before May 13, 2026, foregrounding the constitutional architecture of Article 164 and the floor-test convention. This article is about constitutional process – not electoral counts.
The Constitutional Sequence
| Step | Constitutional Provision | Substance |
|---|---|---|
| 1. Appointment of CM | Article 164(1) | Governor appoints the CM (by convention, the leader who commands a majority in the Assembly) |
| 2. Other ministers | Article 164(1) | Other ministers appointed by the Governor on the CM’s advice |
| 3. Cabinet size | Article 164(1A) | Total ministers cannot exceed 15 per cent of total Assembly strength (91st Amendment, 2003) |
| 4. Oath of office | Article 164(3) read with Third Schedule | Governor administers oath in Form IV; secrecy oath in Form V |
| 5. Majority test | Convention, repeatedly affirmed by SC | Floor test on the floor of the House |
| 6. Six-month rule | Article 164(4) | A minister not a member of the Legislature must become a member within six consecutive months |
Article 164(4) – The Six-Month Window
Text:
“A Minister who for any period of six consecutive months is not a member of the Legislature of the State shall at the expiration of that period cease to be a Minister.”
Reading the provision
- It does not authorise the appointment of a non-MLA per se – it merely tolerates a six-month gap for someone otherwise eligible
- The corresponding Union provision is Article 75(5)
- A person disqualified under Article 173 (for membership) or Article 191 (for disqualifications) cannot be appointed – the six-month grace does not heal disqualification
B. R. Kapur v. State of Tamil Nadu (2001) 7 SCC 231
- Constitution Bench (5 judges) held: A person disqualified under Article 173 read with Article 191 (e.g., on conviction with sentence of 2+ years under Sec 8, Representation of the People Act, 1951) cannot be appointed CM even via Article 164(4)
- Applied to the appointment of J. Jayalalithaa as CM in 2001 (later set aside)
- Settled the law: Article 164(4) is not an enabling provision, only a tolerance provision
Other landmarks
- S. R. Chaudhuri v. State of Punjab (2001) 7 SCC 126: The same person cannot be re-appointed minister after the six-month window without being elected in the interim
- Har Sharan Verma v. State of UP (1971) and (1985): Earlier endorsements of the constitutional permissibility of a non-MLA minister within the six-month window
The Oath of Office – Third Schedule
| Form | Content |
|---|---|
| Form IV | Oath of office of Minister for a State (faith and allegiance to the Constitution; uphold sovereignty and integrity; perform duties without fear, favour, affection or ill-will) |
| Form V | Oath of secrecy (will not communicate any matter brought to his/her consideration as Minister, except as required by law) |
The oath is administered by the Governor. The Governor follows the lead of the Chief Minister-designate but exercises constitutional discretion in cases of contested majority (subject to judicial review).
The Floor Test – A Constitutional Convention
The expression “floor test” does not appear in the Constitution, yet the Supreme Court has repeatedly elevated it to the sole legitimate test of a Government’s majority:
| Case | Holding |
|---|---|
| S. R. Bommai v. UoI (1994) 3 SCC 1 | The strength of a Government must be tested on the floor of the House, not via the Governor’s subjective satisfaction |
| Rameshwar Prasad v. UoI (2006) 2 SCC 1 | Dissolution of Bihar Assembly held unconstitutional; reaffirmed floor-test primacy |
| Nabam Rebia v. Deputy Speaker (2016) 8 SCC 1 | Reaffirmed Governor’s limited discretion in calling for a floor test |
| Shivraj Singh Chouhan v. Speaker, MP Assembly (2020) 7 SCALE 689 | A composite floor test can be ordered; speaker cannot delay indefinitely |
Government Formation – The Sarkaria Order
The Sarkaria Commission (1988) laid down the conventional precedence the Governor follows when no single party has a clear majority:
- The leader of the pre-poll alliance commanding majority support
- The single largest party able to form Government with the support of others, including independents
- A post-electoral coalition with all partners joining the Government
- A post-electoral coalition with some partners providing outside support
The Punchhi Commission (2010) reaffirmed this framework and recommended that the Governor’s decision in such cases be reasoned and recorded.
Who Joined the Council of Ministers
Vijay’s swearing-in included nine ministers of the TVK-led alliance, sworn in alongside him on May 10. The composition reflects the alliance partners’ representation (Congress, CPI, CPI(M), VCK, IUML). The full Cabinet may be expanded within the 15 per cent cap of 234 = 35 ministers under Article 164(1A).

- Floor test and Government formation conventions
- Anti-defection law (Tenth Schedule) – relevant if cross-voting in floor test
Mains Angles
- Article 164(4) is not an enabling provision – it is a tolerance provision. Discuss with reference to B. R. Kapur (2001).
- Compare the constitutional duties of the Governor on Government formation as per Sarkaria and Punchhi Commission recommendations.
- The floor test has emerged as the sole legitimate test of majority. Trace its evolution through S. R. Bommai to Shivraj Singh Chouhan.
