Drugs at sea: boarding, jurisdiction and the routes

On the high seas a vessel is subject to its flag state, and that rule governs everything that follows. A state suspecting a ship of trafficking may request the flag state's authorisation to board, and the 1988 United Nations convention sets out the mechanism. Which country ends up prosecuting is settled by that exchange, frequently within hours.
For a crew that matters more than the cargo. The defence questions follow from the same rule: whether authorisation was given and when, whether the vessel was genuinely stateless or treated as such because nobody answered, and on what basis the boarding state acquired jurisdiction to prosecute instead of transferring the case.

In brief
- A vessel inside territorial waters falls under the jurisdiction of the coastal state, which is the state that then prosecutes.
- A flagged vessel on the high seas falls under its flag state, so boarding it requires that state's authorisation.
- Requests to the flag state are made under the convention mechanism and are frequently granted within hours, which is how the prosecuting country is in practice chosen.
- A vessel without a flag has no such protection and may be boarded by any state, which is why claims about registration are examined closely.
- A vessel refusing to identify itself is treated as potentially stateless, and that treatment is a frequent basis for boarding.
- Semi-submersible craft and fast boats are usually unflagged, and they are boarded without any authorisation being sought.
- Whether authorisation came before or after the boarding is a real question, because an authorisation obtained afterwards is not the same thing.
- The route shapes who is on board: crews on the Atlantic route are typically recruited for a voyage, paid a fraction of the value and told nothing about the structure behind it.
- Container flows through the large European ports are a different kind of case entirely, built on documents, access records and communications rather than on a boarding.
- Everybody aboard is normally charged with the whole cargo, with the quantity driving the bracket, so what separates crew members is knowledge, payment, function and whether they could have left.
- Coastal deliveries by small craft turn on ownership and hire of the vessel, which become effectively the whole of the evidence.
How an interdiction works
| Situation | Rule | Consequence |
|---|---|---|
| Vessel in territorial waters | Coastal state jurisdiction | That state prosecutes |
| Flagged vessel on the high seas | Flag state jurisdiction | Boarding requires its authorisation |
| Request to the flag state | Under the 1988 convention | Frequently granted within hours |
| Stateless vessel | No flag protection | Any state may board |
| Vessel refusing to identify | Treated as potentially stateless | A frequent basis for boarding |
| Semi-submersibles and go-fasts | Usually unflagged | Boarded without authorisation |
The defence questions follow directly. Was authorisation given, by whom, and before or after the boarding? Was the vessel genuinely stateless, or was the claim of statelessness the product of a refusal to answer? And on what basis did the boarding state acquire jurisdiction to prosecute rather than transfer?
The routes, and why they matter to a case
- The Atlantic route, from South America towards the Iberian peninsula and West Africa, where the crews are frequently recruited far from the organisers.
- The Strait, fourteen kilometres of water under permanent surveillance, dealt with in the guide for Tarifa.
- The container flows into Rotterdam, Antwerp, Hamburg, Genoa and Valencia, which are a different kind of case entirely.
- The Balkan route, overland from the east, generating vehicle and freight cases along the corridor.
- Coastal deliveries by small craft, where ownership and hire of the vessel become the whole of the evidence.
The route matters because it shapes who is on board. Crews on the Atlantic route are typically recruited for a single voyage, paid a fraction of the value, and have no knowledge of the structure behind it — which is a real argument on role and on the association charge, not a plea for sympathy.
The crew's position
Everyone aboard is normally charged with the whole cargo, and the quantity drives the bracket. What separates the members of a crew is what they knew, what they were paid, whether they could have left, and what their function actually was.
Where a single voyage is charged as membership of an organisation, the step is contestable on the same grounds as everywhere: structure, shared purpose and stability, rather than participation in one shipment. That is set out in the guide on trafficking association charges.
Who may board a vessel and who then prosecutes depends on flag and position, and the table sets out the combinations.
| Situation | The rule | Consequence |
|---|---|---|
| Vessel inside territorial waters | Coastal state jurisdiction | That state prosecutes |
| Flagged vessel on the high seas | Flag state jurisdiction | Boarding requires its authorisation |
| Request made to the flag state | Under the convention mechanism | Frequently granted within hours |
| Vessel without a flag | No flag protection | Any state may board it |
| Vessel refusing to identify itself | Treated as potentially stateless | A frequent basis for boarding |
| Semi-submersible craft and fast boats | Usually unflagged | Boarded without authorisation |
After the landing
Detention follows the rules of the state that took the case, and for a crew arrested at sea the practical problem is acute: no address anywhere in that country, no ties, no documents. That is the profile on which custody is ordered, and the answer includes supervision enforced in the country of residence, described in the guide on pre-trial detention abroad.
Frequently asked questions
Can any country board a ship at sea?
On the high seas a vessel is subject to its flag state. Boarding by another state normally requires the flag state's authorisation, which the 1988 convention provides a mechanism for.
What if the vessel had no flag?
A stateless vessel has no flag protection and may be boarded. Whether it was genuinely stateless, or was treated as such after a refusal to answer, is contestable.
Is the whole crew charged with the whole cargo?
Usually yes, with the quantity driving the bracket. What separates crew members is knowledge, payment, function and whether they could have left.
Why am I being held when I live abroad?
Because a crew arrested at sea has no address or ties in that country. Supervision enforced in your country of residence is the answer that is almost never requested.
If a vessel has been boarded
The authorisation, the flag and the timing of the boarding are the first things to establish. First contact is free and covered by professional privilege, at any hour.
Who is told that a vessel has been boarded
The news reaches families in fragments. A shipping agent calls to say that a vessel has been stopped. A crew member sends a short message from a satellite phone and then goes silent. A relative reads a press report about a seizure at sea and recognises the name of the ship. In some cases the person concerned is the master or skipper of a yacht, sailing with friends or paid hands. In others he is a deckhand, a cook or an engineer on a cargo vessel, who signed a contract through an agency and had no say in the cargo.
The readers who arrive here are often far from the sea. They are parents, spouses and partners in countries where the crew were recruited. They want to know why a ship was stopped in waters where no state seemed to have authority, which country will hold the crew and whether Italy has anything to do with it. Some have been told that the crew will be taken to Italy; others that they are being held in a country the family never connected with the voyage.
The key to the opening days is a simple rule: on the high seas a vessel is subject to its flag state, and everything that follows flows from that. Another state that suspects trafficking may ask the flag state for authority to board, and which country ends up prosecuting is decided by that exchange, often within hours. This page explains how to read what has happened and what to do while the position is still forming.
The route by which a consignment travelled shapes the case and the people in it, and the table sets out what each produces.
| Route | What the case looks like |
|---|---|
| The Atlantic crossing towards the Iberian peninsula | Crews recruited far from the organisers, for a voyage, for a small payment |
| The strait between the continents | Permanent surveillance and small craft intercepted close to shore |
| Container flows into the large northern and southern ports | Built on documents, access records and communications, with no boarding |
| The overland corridor from the east | Vehicle and freight cases along the route rather than maritime ones |
| Coastal deliveries by small craft | Ownership and hire of the vessel become the whole of the evidence |
Decisions to take while the crew is still on board or just landed
A boarding at sea compresses decisions into hours. Several arise, and each has a price.
- Answering questions on the vessel. Boarding teams ask about the voyage, the cargo, the owner and the route. Whatever is said is noted, and it may be used by whichever state ends up with the case. The price of answering is that you speak without knowing which country will prosecute. The price of declining is that it can be portrayed as non-cooperation. State your name, rank and nationality, and ask for consular contact and for a lawyer.
- Signing papers. Crew are often given documents in a language they do not read. Do not sign a statement about ownership, knowledge of the cargo or the purpose of the voyage without an interpreter.
- Relying on the shipowner or the agency. The company may offer a lawyer. That lawyer may represent the company, whose interests can differ from yours. Ask who is paying and whom the lawyer represents.
- Choosing lawyers in several countries. The state that landed the crew, the flag state and the crew's home state may all have a role. Coordination costs money and time but avoids contradictory moves.
The right order is nearly always: identify yourself, ask for consular contact, ask for counsel, and say nothing about the cargo until you have it.
Papers and records that show who did what on board
In a maritime case the question is usually not whether the substance existed but who knew. The papers that show roles and knowledge matter more than anything else.
- The contract of employment or the engagement letter, with the name of the agency or owner, the rank, the wages and the terms of the voyage.
- Seafarer identity documents, certificates of competence and medical certificates, which show the role you were hired for.
- The crew list and the ship's papers, including the certificate of registry, which show who the flag state is.
- Voyage documents: charter party, cargo manifest, bills of lading, port clearance and any instructions about the route.
- Messages with the owner, the agent, the charterer and other crew, including those on satellite phones and messaging applications, preserved as they are.
- The record of the boarding: the name of the vessel or force that boarded, the time, the language used and anything signed.
- Payslips, bank transfers to the family and the allotment arrangements, which show the pay was ordinary and what was expected.
- Photographs and notes of where crew slept, worked and had access, kept for the lawyer only.
If the originals are on the ship, ask the lawyer to request copies from the owner and to preserve what is held ashore.
What a boarding at sea does to wages, family and a seafarer's future
For a seafarer, the work stops the day the vessel is stopped. Wages often cease, and a family that depended on remittances is left with nothing immediately. The agency that recruited the crew may be unwilling to pay, and the shipowner may decline to answer. Allotments sent home stop, rent and school fees remain, and a relative may have to borrow.
The crew's status on land is uncertain. A landing in a country where nobody has a visa raises questions about immigration status. Medical care, clothing and contact with family all depend on what the authorities allow. Repatriation is not automatic and may need the owner, the flag state or the home state to arrange it. If the crew are released and the case continues, they may not be allowed to leave.
The effects on a career are heavy. A seafarer's record is his livelihood, and an entry connected with a drug seizure can close doors on the whole market. Certificates, visas for crossing ports and insurance may be affected. Skippers of yachts face similar consequences for a charter business, with clients lost and a vessel held. Personal reputations travel through small maritime communities fast. The family should expect questions from the agency, the union and the press, and agree with the lawyer who speaks for them and what is said.
Questions to put to counsel about a seizure at sea
These questions concern the structure of maritime cases, which is unlike a land arrest.
- Which state boarded the vessel, and under whose authority: its own, the flag state's, or by consent?
- Was the flag state asked, when, and how was the answer recorded?
- Was the vessel on the high seas, in territorial waters or stateless, and does it change the state that prosecutes?
- Where were the crew landed, and where is the case likely to be tried?
- How does my rank and my duties on board bear on what I am said to have known?
- What did the boarding team record about me, and have I signed anything?
- Will there be an interpreter in my language at every stage?
- What happens to my wages, my documents and my possessions on the ship?
- Will the crew be kept together or separated by rank, and does that affect their statements?
- Who informs the owner, the flag state and the agency, and what are they entitled to know about my statements?
- If the vessel is released and the crew is not, how is repatriation arranged and who pays?
- If Italy is involved, how does the Italian process connect with the process in the landing state?
Ask for the answers in writing. Maritime cases involve several offices, and written notes help counsel in different countries compare what each was told.
A crew is charged collectively and separated individually, and the table sets out what distinguishes its members and where the material comes from.
| Question about a crew member | Where the answer comes from |
|---|---|
| What did this person know about the cargo | Messages, the recruitment account, what was said on board |
| What were they paid, and by whom | Transfers, cash records, the agreement made before sailing |
| Could they have left the vessel | Ports of call, documents held, control of their passport |
| What was their function on board | Crew lists, watch records, qualifications held |
| Who engaged them and on what terms | Agents, intermediaries and the correspondence with them |
| Had they sailed with these people before | Previous voyage records and employment history |
What not to do after a boarding
The following behaviours harm crews repeatedly.
- Do not discuss the cargo with other crew. Conversations are overheard and later reported, and similar accounts look rehearsed.
- Do not agree a story with the master. The master and crew often have different responsibilities, and a shared story hides differences.
- Do not sign a statement in a language you do not read. Ask for an interpreter and a copy.
- Do not rely on the agency's assurance that everything will be sorted out. Agencies have their own interests and rarely have legal standing.
- Do not post on social media. Crew posts from ports are read by investigators.
- Do not refuse consular contact. It is a safeguard and a route to information for the family.
- Do not ask relatives to contact the shipowner with threats or demands. It creates a record and rarely produces money.
- Do not delete messages from phones kept on board. Deletion is visible and can look like concealment.
- Do not volunteer opinions about the owner or the charterer. A remark made in anger about who must have known can become the accusation against somebody else, and the record of it stays.
- Do not hand over personal phones and laptops without asking what is being copied. The contents reach investigators in several states.
- Do not accept food, medical care or release conditions as a trade for a statement. Basic care is not a bargaining chip. Say so politely and note who proposed it.
When flag, coast, landing and home are all different countries
A maritime drug case may involve a flag state, a coastal state whose waters were crossed, the state where the crew landed and the states of the crew's nationality. Each has its own law, language and procedure. The documents are in several languages, and no authority automatically shares them with the others.
Time at sea creates its own delays. A boarding may take place far from land, and the crew are taken to a port that may be days away. Contact is by satellite telephone, if allowed, and by the consulate when they land. Time zones differ widely between the crew's home countries and the place of detention, so families should agree with the lawyer on a regular hour for updates and expect delay between a hearing and the news of it.
Consulates of the crew's nationalities matter. Each can confirm detention, pass messages, ask for interpreters and monitor conditions. They do not discuss the evidence or run the defence. Where the crew are of several nationalities, the consulates may coordinate, but they cannot choose a common strategy. Lawyers in the landing state, in the flag state and, where Italy is involved, in Italy should speak to each other, since a statement given in the landing state may be read in the flag state. Documents such as the registry certificate, the charter and the contract need accurate translation, and a loose translation of a rank or a duty can change how knowledge is attributed.
How the firm works when the case begins at sea
Send what you have to avvmassimoromano@gmail.com or by WhatsApp: the name of the vessel, the flag, the date of the boarding, the names of the crew and any paper held by the family. The telephone number is on this page. If you do not know the vessel's flag, say so, and the lawyer will help work it out.
The opening call fixes the chronology: where the vessel was, who boarded it, where the crew were landed, which authority is questioning them and what has already been signed. The lawyer asks whether the family has heard from the crew and what the agency has said. The call ends with a short list: whom to contact, what to preserve and what not to say.
The firm works in English. Where Italy is connected with the voyage, the lawyer attends proceedings and explains Italian documents in plain terms. Where the landing state is elsewhere, the firm coordinates with counsel there and with the consulates, and does not replace the local advocate. Offices in Rome, Milan and Naples allow attendance in different regions. The engagement is confirmed in writing with the scope stated, and the family receives short written updates after each step, since news from the sea can be slow and unreliable.
Terms from boarding records and flag-state exchanges
The words below come from the page. They appear in boarding reports, in diplomatic notes and in court papers.
- Flag state — the country whose flag the vessel flies and whose law governs it on the high seas.
- High seas — waters beyond any state's territory, where the flag state's authority is the rule.
- Territorial waters — the sea adjacent to a coast, where the coastal state has jurisdiction.
- Stateless vessel — a ship with no valid flag, which gives no protection against boarding by any state.
- Interdiction — the stopping and boarding of a vessel suspected of trafficking.
- Request to the flag state — the formal asking for authority to board, under the United Nations convention on drug trafficking.
- Landing — the bringing ashore of crew and cargo, which usually decides which state prosecutes.
- Crew list — the register of persons aboard, with ranks, which is read for who was responsible for what.
If another term appears in the papers, send it to the lawyer as it is written. Maritime papers mix legal words with seafaring ones, such as master, charter, manifest and bill of lading, and translators sometimes render a rank or a document type in a way that changes who appears responsible. Ask for the original term to be kept beside each translation, and tell the lawyer when a role on board is described differently in different documents.
About the lawyer
Criminal defence is the whole of this practice. Avv. Massimo Romano is enrolled with the Ordine degli Avvocati di Napoli and pleads before the Court of Cassation; the work that reaches him concerns Italian criminal procedure, extradition, European arrest warrants, and cases where an Italian citizen is held by a foreign authority. He takes instructions directly. The first contact is short and factual: what the charge is said to be, where the person is, what has already been signed or handed over. Nothing is promised at that stage, because the file has usually not been read. What follows the call is practical, a list of documents to collect, contact with the authority or with local counsel abroad, and a plan for the next hearing or request. Where relatives do not speak Italian, the conversation continues in their own language, and written updates are sent in that language as well, so nobody relies on second-hand translation.
Ring the office directly, or write on WhatsApp if calling is difficult. Keep beside you the summons or the record of the search, and the name of any lawyer already acting.
