Investigation, Evidence and Sanctions
Domain scope
Investigation, Evidence and Sanctions tests how an alleged customs offence is proved and penalised. It spans administrative and criminal tracks, evidence handling and the choice of sanction.
Core rules
- Investigations need a lawful basis: an audit, a reasonable-suspicion search, a seizure, an interview under caution or a formal request for records. The basis and scope must be recorded.
- Evidence must be relevant, authentic and legally obtained. Documentary evidence includes declarations, invoices, bank records and correspondence. Digital evidence needs hash values, metadata and a documented extraction process.
- The chain of custody links seizure, storage, analysis and production in court. Gaps can make evidence inadmissible or reduce its weight.
- Administrative cases usually require the authority to prove the facts on the balance of probabilities; criminal cases require proof beyond reasonable doubt. Do not import criminal standards into a penalty notice without checking the governing law.
- Sanctions include assessment of duty, monetary penalty, seizure or forfeiture, suspension of authorisations and prosecution. Proportionality, intent, repetition and cooperation affect the outcome.
Worked example
An audit shows an importer declared the same goods at 60% of the correct value for eight months. Reasoning: obtain the declarations and commercial records, compare identical goods, interview the declarant, and calculate the duty and VAT loss month by month. Preserve the calculation and source documents. Issue an assessment first; then decide whether the misstatement was careless or deliberate. A penalty must cite the legal provision and give reasons and appeal rights.
Traps
- Relying on intelligence alone as proof of the offence.
- Breaking the chain of custody by storing seized goods without a record.
- Interviewing without the required caution or legal basis.
- Confusing a duty assessment with a penalty.
- Ignoring time limits and the right to be heard.
