Arrested in Basel: three borders in one city
Basel sits at the point where Switzerland, Germany and France meet, with an airport operated jointly with France and a river port that is Switzerland's access to the sea. Almost every case here has a border in it. Swiss procedure applies where the stop took place on the Swiss side: police custody, then a period for the prosecutor, then a decision by the compulsory measures court within a short fixed period of the arrest.
The airport point is not academic. The French and Swiss sectors sit side by side, and being stopped in the French sector engages French procedure with a different clock, a different prosecutor and different rules on what a lawyer may do. Establishing which sector the stop happened in is therefore the question to settle before anything else, because it determines the whole of the procedure that follows.

In brief
- Which sector of the binational airport the stop took place in decides which country's procedure applies, and the answer cannot be assumed from the destination printed on the ticket.
- Switzerland sits outside the EU customs union, so declaration obligations on cash and goods apply on entering and on leaving, in each direction, and travellers familiar with internal EU travel are regularly caught by this.
- Goods, cash and vehicles crossing in either direction generate the bulk of the local caseload, and the paperwork that answers such a case is created at the moment of the crossing rather than afterwards.
- The Rhine port produces freight and customs matters and occasionally narcotics files, with the same structure as other European ports: the shipment is identified before any suspect is.
- Cross-border workers live and work in different countries, which complicates service of documents, assessment of ties for detention purposes, and the effect of any measure on employment.
- The pharmaceutical and chemical industry concentrated here produces regulatory, environmental and workplace safety proceedings of its own, in which the company and the individual are exposed on different bases.
- Swiss detention is ordered for periods that are renewed rather than fixed once, and release on a security is rarely granted to someone without ties in the country.
- Because Switzerland is outside the European Union, surrender proceeds by extradition rather than by the European Arrest Warrant, and the timescales are considerably longer.
What three borders produce
- Customs. Goods, cash and vehicles crossing in either direction, with declaration obligations that apply because Switzerland is outside the EU customs union.
- The binational airport, where the French and Swiss sectors sit side by side and which authority intervenes depends on where you were stopped.
- The Rhine port, generating freight, customs and occasionally narcotics cases.
- Cross-border workers, whose residence and employment sit in different countries.
- Pharmaceutical and chemical industry, which produces regulatory, environmental and workplace-safety proceedings of its own.
The airport point is not academic. Being stopped in the French sector engages French procedure, with the framework set out in the guide for France; the Swiss sector engages Swiss procedure. Establishing which one happened is the first question.
The Swiss clock, in short
Twenty-four hours of police custody, twenty-four more for the prosecutor, a decision by the compulsory measures court within four days, and detention of up to three months at a time. The full framework is in the guide for Switzerland.
The Italian side
Where there is an Italian proceeding, a warrant or an alert, the two fronts run together — and with Switzerland outside the European Union, on longer timescales. The framework is in the guide on extradition.
Everything about the procedure depends on which side of a border the stop happened. The table compares the position in each sector of the binational airport.
| Question | Stopped in the Swiss sector | Stopped in the French sector |
|---|---|---|
| Which procedure applies | Swiss criminal procedure | French criminal procedure |
| Who holds the person | Swiss police, then the cantonal prosecutor | French police, under the garde à vue regime |
| Who decides on detention | The compulsory measures court | The liberty and detention magistrate |
| Release against a payment | Possible as a security, rarely for non-residents | Not available: France has no bail |
| What has to be established at once | Which authority intervened, and where | Which authority intervened, and where |
Frequently asked questions
I was stopped at the airport. Which law applies?
It depends on the sector. The airport is operated jointly with France, and the French and Swiss sectors engage different procedures.
Do I have to declare cash?
Yes, in both directions: Switzerland is outside the EU customs union, so the obligation applies on entering and on leaving.
How long can they hold me?
Twenty-four hours by the police and twenty-four more by the prosecutor, with the compulsory measures court ruling within four days of the arrest.
Is there an equivalent to the European Arrest Warrant?
No. Surrender between Switzerland and EU states proceeds by extradition, which takes longer and turns on different grounds.

The decisions that follow a stop at a border city
Almost every case in Basel has a border in it, which means every case has a choice about which country's process you will be dealing with.
Speak at the border, or ask for a lawyer. Questions at a crossing sound routine: what are you carrying, where is the money from, where are you going. The exchange is informal in tone but formal in effect. An answer given in the car park of a customs post can become the foundation of a later file. Declining to explain without a lawyer costs you time at the crossing but keeps your account clean.
Accept a customs penalty, or contest it. Because Switzerland is outside the EU customs union, goods and cash crossing in either direction carry declaration obligations. An officer may offer to settle the matter by payment. That can close it quickly, but it may also amount to an admission. Ask what the document says before you agree to anything, and have it translated.
Tell your employer in Germany or France, or stay quiet. A cross-border worker's residence and employment sit in different countries, and an arrest in one can raise questions in the other. A short statement may protect the job, but you must know what to say.
Choose which country's lawyer you need. The binational airport sits across a frontier, and which authority acts depends on where you were stopped. The lawyer you need may be Swiss or French, depending on the sector. Getting this wrong wastes time. Describe exactly where the stop happened, and which side of the sector line you were on.
The borders around the city shape the caseload. This table sets each source of cases beside the matter it generates and what decides it.
| Source | Typical case | What decides it |
|---|---|---|
| Customs crossings | Undeclared cash, goods or vehicles | Whether a declaration obligation applied in that direction |
| The binational airport | Luggage and customs matters, and arrests on alerts | Which sector the stop occurred in |
| The Rhine port | Freight, customs and occasionally narcotics files | Whether access to a consignment implies knowledge of it |
| Cross-border employment | Matters where residence and work are in different states | Where documents were served and where ties actually are |
| Pharmaceutical and chemical industry | Regulatory, environmental and safety proceedings | How the activity was organised and documented |
Work, residence and money across three systems
A person arrested in Basel often lives in one country, works in another and was travelling through a third. That layering shapes everyday life after an arrest more than almost anything else.
Cross-border workers are the clearest case. Their employment contract is in one place and their home in another, and the authority that arrested them may be in neither. An employer will want an explanation, a landlord may ask questions, and a tax or social security question can open up at the same time. Your right to cross the border for work may also be affected if you are subject to a restriction or a recorded finding.
The pharmaceutical sector adds its own pressure. Staff in a regulated business may find that any proceeding triggers a review inside the company, a suspension of access to premises or systems, and questions about whether they can continue in a role that involves trust. If your employer is a large international firm, its compliance function will be involved before you have spoken to anyone.
For drivers and freight staff, a vehicle may be held, a load delayed and a client lost. A hire company will want its vehicle back. For travellers, the stop may mean missed connections, a hotel booking wasted and family members trying to arrange a flight to an airport that sits on a border.
If the money found on you is lawful, document its origin now. The question of where it came from is the question that will follow you through every stage.
What to leave alone at the crossing and afterwards
- Do not sign what you cannot read. A customs or police document may be in German, French or Italian, and may record an admission.
- Do not explain cash or goods on the spot. The explanation will be checked against every document later.
- Do not discuss the case with fellow travellers or colleagues. Their accounts and yours will be compared.
- Do not post on social media. Employers and authorities read it.
- Do not assume the authority that stopped you is the one that will deal with the file. Ask who has jurisdiction.
- Do not delete messages or transaction records. Deletion looks like concealment and can often be reversed.
- Do not cross the border again until you have been told whether you may. A second crossing can create a second problem.
Papers that show where you live, work and travel
- Passport or identity card and residence permit if you have one, with photographs of every page.
- Employment contract and recent payslips, especially if you work in a different country from where you live.
- Proof of address in your country of residence, such as a tenancy or utility bill.
- Proof of the origin of any cash: bank withdrawals, sales papers, invoices.
- Vehicle documents, insurance and hire agreement, with the registration country noted.
- Delivery and customs papers for any goods you were carrying.
- Travel bookings showing where you started and where you were going.
- Anything handed to you by officers, with the name, the time and the sector or post where it happened.
- Contact details of your employer's human resources and of one person who can confirm your movements.
Readers used to moving between EU member states expect mechanisms that do not exist here. The table compares the position.
| Question | Between EU member states | Between Switzerland and the Union |
|---|---|---|
| Surrender of a wanted person | The European Arrest Warrant, between judicial authorities | Extradition, on different grounds and longer timescales |
| Obtaining evidence | The European Investigation Order | Requests for mutual legal assistance |
| Declaring cash and goods | No customs obligation on internal movement | Obligations apply on entering and on leaving |
| Supervision in place of detention | Can be enforced in the person's own state | Not available through the European mechanism |
| Pace of the case | Fixed and enforceable periods | Longer, with steps outside the courts involved |
The Italian side, and how the firm handles a border case
Contact the firm by phone or by email to avvmassimoromano@gmail.com. A relative, an employer or you yourself can begin the engagement. The opening call asks where you were stopped, which side of the border it was on, what papers you have been given and what you have said.
The firm does not appear as counsel in Swiss or French courts. It briefs a lawyer admitted in the right country, and it handles the Italian side: communication with the family, coordination of documents, and any Italian element, such as an Italian employer, an Italian company or an Italian connection to the file. For border cases the first task is often working out which jurisdiction applies, and the firm helps with that before any statement is made.
Work is in English and Italian. Interpreters for German or French are arranged through the local lawyer. The firm is reachable outside office hours, and documents may be sent as photographs or scans.
Because more than a single country is often involved, the firm keeps a written note of who is acting in each place and on what, so that a decision taken in one country does not undermine a position in another.
Questions about borders, sectors and cross-border workers
- Which country's authority has the file, and does that change which lawyer I need?
- If I was stopped in the binational airport, which sector was I in, and what follows from it?
- What are the deadlines the law sets at this stage, and who is watching them?
- If cash or goods were taken, how do I show where they came from?
- Will this affect my right to cross the border for work?
- What should I tell my employer, and in which country?
- If I work in a regulated sector, does the proceeding trigger a review inside my company?
- Can I leave the country, and where must I be for hearings?
- How is the work divided between the local lawyer and the firm?
Terms from customs, border and cross-border files
Customs. The authority and the rules that control goods and cash crossing a border. In Switzerland they apply in both directions because the country is outside the customs union.
Declaration obligations. The duty to declare cash and certain goods on crossing. A failure to declare is an issue on its own, even if the money is lawful.
Binational airport. An airport operated jointly by two countries, with sectors belonging to each. Which authority acts depends on the sector.
Rhine port. The river port, which generates freight, customs and sometimes narcotics matters.
Cross-border worker. A person who lives in one country and works in another, whose residence and employment may each be affected by an arrest.
European Arrest Warrant and extradition. Procedures for handing a person to another country, used when a case has an international element.
About the lawyer
A relative detained abroad changes the shape of a family's day: nobody knows who to call first, and the information that does arrive is fragmentary. Avv. Massimo Romano works on Italian criminal matters, European arrest warrants and the position of Italians arrested outside Italy, and he is admitted to plead before the Court of Cassation. The office works from Rome, Milan and Naples, which matters when papers have to be filed in one city while the family lives in another. Contact usually begins with a telephone call or a WhatsApp message describing, in plain terms, what happened. He reads whatever paperwork exists before giving an opinion; if something is missing, he says what to ask for and who to ask. After that first conversation the family receives a written account of the position and the steps that follow. Discussions with relatives are held in the language they use at home.
Telephone the office or send a WhatsApp message. Before you call, gather the document you received, the name of the authority written on it, and the file reference if one appears.
