Union Government
(1) The validity of any proceedings in Parliament shall not be called in question on the ground of any alleged irregularity of procedure. (2) No officer or member of Parliament with powers to regulate procedure, conduct of business, or maintain order in Parliament shall be subject to any court's jurisdiction in exercising those powers.
Courts generally cannot second-guess how Parliament conducted its own internal procedure - even if there was some procedural irregularity, that alone doesn't make Parliament's decision legally invalid, and officers like the Speaker exercising their procedural/disciplinary powers are shielded from being taken to court over how they exercised them.
This is why a court will generally decline to strike down a law purely because a petitioner alleges some technical procedural irregularity occurred while it was being debated or passed in Parliament - courts respect Parliament's internal procedural autonomy under this article.
