Importation of Jewellery: When the French Supreme Court Quashes an Acquittal for Lack of Reasoning

Imagine a trader in Onet-le-Château, specialising in the purchase and sale of second-hand jewellery. He receives a batch of gold jewellery, supposedly from a European Union country. He displays it in his shop window, sells it, and everything seems normal. But one day, customs officers arrive: seizure, report, threat of prosecution for smuggling imports. The trader is convinced he is in order: the jewellery bears hallmarks, proof of its EU origin, right?

Yet the question is more complex than it appears. Are hallmarks sufficient to prove the legal origin of goods? The lower courts said yes, but the French Supreme Court said no. And that is where the problem lies.

This decision of 22 October 2008 (No. 08-80.843) is a warning for all professionals handling goods subject to proof of origin. It reminds us that proof of EU origin is not limited to the presence of hallmarks: it is also necessary to demonstrate that these hallmarks were affixed lawfully and that the goods were not fraudulently removed from the customs territory. Explanations follow.

The facts: a story that happens every day

The case began with a customs inspection at several gold buying and selling businesses in Bordeaux and Paris. Officers seized gold jewellery, mainly rings, bracelets and necklaces, for which the traders could not present documents proving their origin (purchase invoices, certificates of provenance, etc.). The defendants were prosecuted for smuggling imports of goods subject to proof of origin, under Article 215 of the Customs Code.

Before the criminal court, some were convicted, others acquitted. The customs administration appealed. The Bordeaux Court of Appeal, in its judgment of 7 February 2008, partially acquitted the defendants on the grounds that the hallmarks on some of the seized jewellery attested to their EU origin and satisfied the requirements of Article 215 of the Customs Code. In other words, the Bordeaux judges considered that the mere presence of a hallmark (a small symbol engraved on the metal, such as the eagle's head for gold in France) sufficed to prove that the jewellery was manufactured or put into circulation in a European Union country, and therefore was not subject to customs formalities.

But the customs administration disagreed. It appealed to the Supreme Court, arguing that the Court of Appeal had not sufficiently reasoned its decision. The Supreme Court agreed: it quashed the appeal judgment for lack of legal basis, citing Article 215 of the Customs Code and Article 593 of the Code of Criminal Procedure (which requires judgments to be reasoned).

The reasoning of the court — dissected

To understand this decision, one must first grasp what Article 215 of the Customs Code provides. This provision requires that any imported or exported goods be accompanied by documents proving their origin. For gold jewellery, this proof may be provided by hallmarks, but only if they have been affixed by an approved body and the goods have not been fraudulently introduced into the customs territory.

The Bordeaux Court of Appeal had merely noted the presence of hallmarks to conclude EU origin. But the Supreme Court criticised it for not verifying whether these hallmarks were authentic and lawful, and especially whether the goods had not been fraudulently removed from customs supervision. In short: a hallmark can be forged. The lower courts should have ensured that the jewellery had not been imported in smuggling despite the hallmarks, for example from non-EU countries where they might have been fraudulently hallmarked.

The Supreme Court thus recalls a fundamental principle: the reasoning of court decisions must be complete and not contradictory. In this case, the Court of Appeal did not respond to the customs administration's arguments contesting the lawfulness of the hallmarks. It therefore insufficiently reasoned its decision, justifying the quashing.

This decision is neither a development nor a reversal, but a simple application of the rules on reasoning. However, it has considerable practical significance for professionals: it requires them to keep solid proof of the origin of their goods, beyond mere hallmarks.

What this changes for you — concretely

If you own a jewellery shop in Villefranche-de-Rouergue, this decision directly concerns you. You must be able to prove the origin of every piece of jewellery you sell, even second-hand. Hallmarks are no longer enough: you need purchase invoices, certificates of provenance, or any document establishing that the jewellery was manufactured or put into circulation in the EU lawfully.

For real estate professionals, this case may seem distant. But it illustrates a principle that also applies in your field: proof of the origin of an asset (for example, land or a building) must be rigorous. A title deed may be challenged if it is insufficiently reasoned. Similarly, for co-owners, justification of the origin of funds in a transaction may be required by the bank or tax authorities.

Let us take a numerical example: in Onet-le-Château, a jeweller buys a batch of 50 gold rings from an individual for €5,000. He resells them for €8,000. If customs inspect and he cannot prove the origin of the rings (no invoice, no lawful hallmark), he risks a customs fine of up to the value of the goods (€8,000) and confiscation of the jewellery. Not to mention legal fees and lost time.

If you are in this situation, you must demand from your suppliers written documents stating the origin of the goods, and keep these documents for at least 5 years (customs limitation period).

Four tips to avoid this type of dispute

• Demand detailed invoices: for each jewellery purchase, request an invoice stating the weight, fineness (carats), provenance and hallmark number. Keep these invoices in a dedicated file.
• Verify the authenticity of hallmarks: learn to recognise official hallmarks (eagle's head for gold, scallop shell for silver) and be wary of abnormal or overly worn hallmarks. If in doubt, have the jewellery appraised by a professional.
• Declare your stocks to customs: if you regularly import jewellery, you can submit a summary declaration or transit document. This will protect you in the event of an inspection.
• Consult a specialist lawyer: before buying a large batch of second-hand jewellery, especially at auctions or stock purchases, have the customs compliance checked by a lawyer. The cost (a few hundred euros) is negligible compared to the risks.

Further reading: related case law and developments

This decision is part of a series of Supreme Court judgments recalling the requirement for lower courts to give reasons. For example, in a judgment of 12 February 2008 (No. 07-80.123), the Court had already quashed a court of appeal that had merely asserted the absence of fraud without analysing the evidence. Here, the same principle is applied to hallmarks.

In customs matters, the trend is towards strengthening justification obligations. Judges are increasingly strict on proof of origin of goods, particularly to combat trafficking in cultural goods and precious metals. Since 2008, several texts have strengthened controls, such as Regulation (EU) 2019/880 on the import of cultural goods.

For professionals, the future is clear: it will be necessary to digitise proof of origin (scan invoices, photograph hallmarks) and keep them on a secure platform. Customs already uses artificial intelligence to detect anomalies in declarations. Better to anticipate.

In practice: what to do

Checklist for purchasing second-hand jewellery:

1. Obtain an invoice with the seller's name, address and SIRET number.
2. Check the hallmark (eagle's head for 18-carat gold, for example).
3. Take a photo of the hallmark and the item.
4. Keep all documents in a physical and digital file.
5. If in doubt about origin, refuse the purchase or request an appraisal.

FAQ:

Q: Can I sell jewellery without an invoice if I have a hallmark?
A: No, since this decision, a hallmark alone is not sufficient. You need a written document (invoice, certificate) proving lawful origin.

Q: What should I do if customs inspects me?
A: Stay calm, do not lie, and present all documents in your possession. If you have nothing, say you will provide them within 15 days (legal deadline). Consult a lawyer immediately.

Q: What are the penalties for smuggling imports?
A: Fine between one and two times the value of the goods, confiscation of the items, and sometimes imprisonment (rare for jewellery).

Q: Do I need to declare my jewellery to customs if I buy it online from another EU country?
A: No, if the purchase is from a professional and the seller invoiced VAT of the country of origin. But keep the invoice and proof of delivery.

Q: Can an individual be prosecuted for smuggling imports?
A: Yes, if they import jewellery without proof of origin, even for personal use. Customs can seize the items and impose a fine.
