Common Portal service requires effective access to complete GST notices and orders, preserving hearing rights and appellate limitation.
GST service through the Common Portal is an express statutory mode, but portal availability must be distinguished from effective service of an adjudicatory communication. Rule 142 preserves the distinction between a substantive show cause notice or order and its electronic summary in FORM GST DRC-01 or DRC-07. Electronic summaries do not, without more, demonstrate communication of complete allegations, grounds, facts and reasons. Portal-based service must be assessed by statutory compliance, accessibility of the complete communication, and the taxpayer's real opportunity to respond, particularly where appellate limitation is involved.
