Interception procedure: only goods or conveyances shown to violate GST provisions may be detained; repeat checks barred absent new information. Timeline language is amended so 'three working days' becomes 'three days' and FORM GST MOV-05 release wording is prescribed. Under rule 138C(2), a conveyance physically verified in one State/UT shall not be re-verified elsewhere unless specific information of tax evasion arises. Hard copies of notices/orders may serve as proof of prior action where portal forms are unavailable. Detention or confiscation must be limited to goods and conveyances for which a violation of the GST Acts or rules is established; partial detention is permissible only for the noncompliant consignments.
