Relations Between Union and States
An Act (or provision) isn't invalid merely because a required recommendation or prior sanction was missing, as long as the actual assent was given by whichever of the Governor/President (or the historical Rajpramukh) was empowered to give it - even if that assent came from a different one of those office-holders than the one whose recommendation was technically required.
This is a practical, error-forgiving provision: if a Bill needed, say, the Governor's prior recommendation to be introduced, but that step was skipped, the resulting Act isn't automatically invalidated as long as the final assent itself came from an appropriately empowered authority - treating certain procedural requirements as curable technicalities rather than fatal legal defects.
This provision prevents a law from being struck down purely on a technical procedural oversight (like a missing prior recommendation) if the substantive assent requirement was still properly satisfied by an appropriate authority.
