Worked examples — five live scenarios
Example 1 — Rule laid and not modified
Facts: CGST (Amendment) Rules 2024 are laid before both Houses. 30-day cumulative period of laying completes without any modification or annulment.
Analysis: Standard operative path. Section 166 compliance achieved. The amended Rules operate with original effective date and remain unchanged. No parliamentary intervention. Practitioner analysis — focus on substantive defences if challenges arise.
Result: Rules operate as originally made. Section 166 oversight check exercised but no modification.
Example 2 — Rule modified by Parliament
Facts: A Rule is laid. Both Houses concur on modification — specific sub-rule struck down. Some taxpayers have already complied with the pre-modification sub-rule.
Analysis: Sub-rule operates in modified form from the date of parliamentary action. Past compliance with the pre-modification sub-rule is protected by 'without prejudice' clause. Taxpayers' past actions remain valid. Future compliance follows modified Rule.
Result: Modification effective prospectively. Past actions protected. Vatika prospective-operation framework analogously applies.
Example 3 — Failure to lay challenge
Facts: Taxpayer challenges a Rule alleging non-laying before Parliament. Documentary evidence of laying is not found in parliamentary records.
Analysis: Failure-to-lay is generally procedural, not jurisdictional. Instrument remains valid unless extreme failure. Practitioner challenge anchored solely in failure-to-lay is weak. Coordinate with substantive grounds — intra-vires, retrospective-operation, constitutional-rights. Government's primary defence — preserve laying records; for any gap, demonstrate the procedural rather than jurisdictional character.
Result: Failure-to-lay alone is unlikely to invalidate the instrument. Coordinated with substantive grounds, may add procedural weight.
Example 4 — Notification's effect post-annulment
Facts: A Notification (exemption framework) is laid and annulled by both Houses. Taxpayer applied the exemption during the operative period.
Analysis: Annulment is prospective. Past actions under the pre-annulment Notification are protected. Taxpayer's claimed exemption during the operative period is valid. From the date of annulment, exemption is no longer available; subsequent transactions are taxable.
Result: Past-period exemption preserved. Future-period taxability re-established. Without-prejudice clause directly applies.
Example 5 — Coordinated substantive and procedural challenge
Facts: A Regulation is challenged as ultra vires (substantive) and as not laid before Parliament (procedural).
Analysis: Build challenge primarily on substantive grounds — Regulation exceeds Act-and-Rules conformity (Calcutta Discount Co. framework). Procedural ground (non-laying) operates as supplementary. Even if procedural ground is held insufficient, substantive challenge may succeed. Coordinated approach maximises challenge probability.
Result: Substantive ground is primary; procedural is supplementary. Coordinated strategy appropriate.
