Consolidated GST show cause notices may cover multiple financial years, while each demand component remains independently subject to limitation.
Sections 73 and 74 do not expressly bar a common show cause notice covering multiple tax periods or financial years. The expressions "for any period" and "such periods" support consolidation, while financial-year references in the limitation provisions govern the deadline for adjudication orders rather than the scope of notice issuance. Each component demand must independently satisfy applicable limitation requirements. Section 74 requires disclosed material supporting fraud, wilful misstatement, or suppression of facts to evade tax; its extended limitation is not automatic.
