The Constitution requires every member of a State Legislature to take an oath or make an affirmation before taking their seat.
The main constitutional provision is:
Article 188 — Oath or affirmation by members
The oath or affirmation ensures that State Legislators formally commit themselves to:
The oath and affirmation of State Legislators are governed primarily by:
Article 188
The form of the oath or affirmation is provided in:
Third Schedule
Related provisions include:
Every person elected to a State Legislature must make and subscribe an oath or affirmation before taking their seat.
This applies to members of:
Therefore:
Assembly Member → Oath/Affirmation
Council Member → Oath/Affirmation
Under Article 188, the oath or affirmation is made before:
Governor
or:
A person appointed by the Governor for this purpose
Therefore, the constitutional authority is:
Governor → Administers oath or appoints person to administer it
In practice, the Governor commonly authorises the:
Pro Tem Speaker
to administer the oath or affirmation to newly elected members of the Legislative Assembly.
However, the constitutional provision itself states:
Governor or person appointed by Governor
Therefore, the Pro Tem Speaker does not derive the authority independently from the Constitution merely by being Pro Tem Speaker.
A member has the option to make:
Oath
or:
Affirmation
The Constitution therefore accommodates both religiously expressed oath-taking and a non-religious affirmation.
The constitutional form is prescribed in the:
Third Schedule
A State Legislator undertakes to:
The oath therefore establishes a constitutional commitment before the member takes their seat.
A member must make and subscribe the oath or affirmation:
Before taking their seat in the Legislature
The oath is therefore a constitutional prerequisite for participation as a member.
If a person:
they are liable to a:
Penalty of ₹500 for each day
on which they sit or vote.
This is an important UPSC Prelims fact.
The penalty under Article 193 is:
₹500 per day
It is not a penalty for:
It applies when a person:
Sits or votes before taking the required oath or affirmation, or does so while knowingly unqualified/disqualified.
Election or nomination gives the person the status of being elected or nominated as a member, subject to constitutional requirements.
The oath is required before the person can:
Take their seat and participate as a member in the House.
Therefore, do not treat oath-taking as the event that itself elects or appoints the member.
For a newly elected Legislative Assembly:
General Election
↓
Members elected
↓
Governor appoints Pro Tem Speaker
↓
Oath / Affirmation
↓
Initial proceedings
↓
Speaker elected
↓
Regular Assembly functioning
The Pro Tem Speaker commonly administers the oath when authorised by the Governor.
12. Oath and Legislative Council
The same constitutional principle applies to members of the:
Legislative Council
A Council member must also make and subscribe the prescribed oath or affirmation before taking their seat.
The Council is a permanent House, but newly elected or nominated members must still complete the constitutional oath requirement.
13. Oath of Ministers vs Legislators
Do not confuse:
Legislator's Oath
with:
Minister's Oath
Legislator
Article 188
Minister
Article 164
The oath of office and secrecy for State Ministers is administered by the:
Governor
according to the constitutional forms.
14. Oath of Governor vs Legislator
These are also different.
Governor
Oath under:
Article 159
State Legislator
Oath under:
Article 188
Therefore:
Article 159 → Governor's Oath
Article 188 → Legislator's Oath
15. Third Schedule
The:
Third Schedule
contains the forms of oath or affirmation for various constitutional offices and positions.
For State Legislators, the relevant form is prescribed for:
Members of State Legislatures
The form applies to members of both Houses, subject to the constitutional framework.
16. Oath and New Members
Whenever a new member enters the State Legislature, the constitutional oath requirement applies.
This includes members entering through:
General election
By-election
Nomination, where applicable
The member must complete the required oath or affirmation before taking their seat.
17. By-Election
A person elected through a:
By-election
must also make and subscribe the required oath or affirmation before taking their seat.
The constitutional requirement applies to the new member even though the existing House is already functioning.
18. Nominated Members
Where the Legislative Council has nominated members under the constitutional framework, those members must also make and subscribe the prescribed oath or affirmation before taking their seats.
Therefore:
Elected Member → Oath
Nominated Member → Oath
19. Oath and Qualifications
A person must satisfy the constitutional qualifications for membership.
The oath does not cure a:
Disqualification
Therefore:
Oath-taking ≠ Removal of Disqualification
A person who is constitutionally disqualified cannot become qualified merely by taking the oath.
20. Oath and Anti-Defection
Oath-taking is separate from disqualification under the:
Tenth Schedule
The oath establishes constitutional commitment, while anti-defection provisions regulate membership consequences arising from certain political conduct.
Therefore:
Article 188 → Oath
Tenth Schedule → Anti-Defection
21. Importance of Oath
The oath serves several purposes.
Constitutional Commitment
It expresses allegiance to the Constitution.
National Integrity
It includes commitment to the sovereignty and integrity of India.
Public Responsibility
It formally recognises the responsibilities associated with legislative office.
Rule of Law
It reinforces the duty to act within the Constitution and laws.
22. Oath and Right to Vote
A person who has not made the required oath or affirmation cannot validly sit and vote as a member of the State Legislature.
Article 193 provides a penalty for sitting or voting before the constitutional requirement has been fulfilled.
Therefore:
Oath → Prerequisite for sitting and voting
23. Oath and Speaker Election
During the initial proceedings of a newly elected Legislative Assembly, members generally take the oath before the election of the regular Speaker.
The Pro Tem Speaker commonly presides over this transitional phase.
The sequence is:
New Assembly
↓
Pro Tem Speaker
↓
Oath of Members
↓
Speaker Election
↓
Regular Speaker
24. Oath and Sessions
The oath is generally administered during the initial proceedings of a newly constituted House or when a new member enters the House.
It is not necessary for every existing member to repeat the oath at the beginning of every legislative session.
Therefore:
New Session ≠ New Oath for Every Member
25. Language of Oath
The constitutional form of oath or affirmation is prescribed in the:
Third Schedule
The member follows the constitutionally prescribed form, subject to the provisions governing the language and administration of the oath.
The essential constitutional commitment remains:
Faith and allegiance to the Constitution + Sovereignty and integrity of India + Faithful discharge of duties
