Article 212 means courts can never look into anything that happens inside a State Legislature.

Courts have clarified that this protection covers only procedural irregularities, not violations of mandatory constitutional provisions or substantive illegality, which can still be examined.

The Speaker's decisions are always completely immune from any judicial review because of Article 212.

Courts have held that when a Speaker acts in a quasi-judicial capacity, such as deciding disqualification under the Tenth Schedule, that decision can be subject to limited judicial review despite Article 212.

The Constitution of India

Article 212

Courts not to inquire into proceedings of the Legislature

(1) The validity of any proceedings in the Legislature of a State shall not be called in question on the ground of any alleged irregularity of procedure.§

(2) No officer or member of the Legislature of a State in whom powers are vested by or under this Constitution for regulating procedure or the conduct of business, or for maintaining order, in the Legislature shall be subject to the jurisdiction of any court in respect of the exercise by him of those powers.§

Why this exists

This Article mirrors Article 122 (which applies to Parliament) and reflects the British parliamentary tradition of separating the judiciary from the internal workings of the legislature. The framers wanted State Legislatures to function without constant judicial interference over technical procedural lapses, and wanted presiding officers to be free to run debates, maintain discipline, and manage House business without fear of being sued or challenged in court for every ruling they make from the chair.

How courts read it

The Supreme Court has generally held that Article 212(1) protects only 'irregularities' of procedure, not substantive illegalities or violations of constitutional mandatory provisions. In cases like Raja Ram Pal v. Lok Sabha (dealing with the parallel Article 122) and earlier in State of Punjab v. Satya Pal Dang, courts have drawn a line: pure procedural lapses are immune from scrutiny, but if a legislative proceeding violates a substantive constitutional provision, courts may still examine it. Similarly, in disqualification and anti-defection matters (like Kihoto Hollohan v. Zachillu), courts have held that a Speaker's decisions, when acting as a tribunal under the Tenth Schedule, are subject to limited judicial review despite Article 212, because such decisions are not mere 'internal proceedings' but final adjudications affecting members' rights.
