Criminal law

Kolokatsi Advocaten is specialized in criminal law in the broadest sense. We represent suspects as well as witnesses and victims. We are always keen on introducing a human rights dimension into our defense.
In criminal cases, it is of the utmost importance that a lawyer is contacted at the earliest possible stage. 

Then we can optimally guarantee and organize your right to a fair trial and your defence.
On your behalf, we then request your criminal file, identify the legal problem and together with you we will find the best legal solution. We also represent you at the hearing. If you are acquitted but were held in pretrial detention, we will do our utmost to ensure you receive an appropriate compensation. If necessary we initiate interim proceedings against the State.

European and international (criminal) law

Criminal law does not stop at our national borders. Crime is often cross-border as are our expert legal knowhow and skills. We speak English, French, German and Greek and have excellent interpreters and translation facilities for the other languages (for example Arabic, Spanish, Polish, Bulgarian, Italian, etc.).
If you have Dutch nationality and you are faced with criminal proceedings abroad or if you are a foreigner facing criminal proceedings in the Netherlands, we can assist you and help you understand the procedures and what is happening. We can also get you an expert lawyer abroad. We work with an extensive network of foreign lawyers and we are a member of the European Criminal Bar Association (ECBA).

We are specialized in the laws relating to surrender of persons and have up-to-date knowledge of European and international criminal law, human rights, extradition and international humanitarian law.

Proceedings before international fora (UN Comittees on Human Rights ECHR and ECJ) are among the possibilities.

Finally, we try to involve European criminal law in all our criminal cases if this will lead to an improvement of the position of our clients. For sometimes European criminal law offers more guarantees for the suspect than Dutch criminal law.

Juvenile (criminal) law

In some aspects, juvenile criminal law has rules differing from adult criminal law. That is why specialist knowledge is essential. In addition to specialist knowledge we also pay extra attention to the interests of the minor.

We represent minors in juvenile criminal cases and in juvenile civil cases, in particular in the context of placement in care in a secure youth care centre.

Central Office for Motor Vehicle Driver Testing (CBR)

In addition to the expertise in the field of traffic crimes, we also have extensive specialist expertise in the area of the so-called ‘CBR procedure’. You may come into contact with the CBR when for example you have driven a vehicle while under the influence of alcohol or drugs. The decisions then taken by the CBR may have a considerable impact on your private and business life, and your finances as well.

By way of illustration: the validity of your driving licence may be suspended with the obligation to undergo a driving ability test. In these cases, it is of the utmost importance to act as quickly as possible. We request your file and assess your options. Then we draft a notice of objection on your behalf and we will do everything possible to get your driving licence back so you can legitimately participate in traffic again.

Medical disciplinary law

When being treated by a doctor, finding a solution to your medical problem is central. Doctors try to treat the patient in the best possible way. However, this does not always lead to a satisfactory solution and the question may arise whether the relevant care provider acted according to his profession’s standards. In this context, a complaint can be lodged to one of the medical disciplinary tribunals. The patient, with no medical knowledge, faces barriers both in medical and legal matters.

The doctor in question often also faces legal hurdles. For example, cases relating to the so-called admissibility requirement (not every care provider or any person may submit a complaint), questions relating to acts or omissions in violation of the duty of care of a care provider, etc. In such a case, we can help. We will help you to understand the legal issues, we will advise you, draft the court documents (written complaint, reply or rejoinder) and assist you with the procedure that may follow.

Interim proceedings against the Netherlands on repatriation of Dutch 'Daesh-children' 

By judgement of November 11th 2019 he Netherlands have been ordered to repatriate 56 children from the detention camps al-Roj and al-Hol in North-eastern Syria. State appealed succesfully. Appeal to Court of Cassation is pending. 

These children risk to be killed by bombings, become victims of sexual assault and torture, freezing winter cold, lack of proper food, medical care, education etc. The living conditions of these 56 children of which the vast majority is under the age of 12 should be qualified as an emergency situation. According to the judge they are the victim of the actions of their parents. The Netherlands has thus been ordered to make all possible effort to return these children.

The children are being represented by a collective of 5 law firms: André Seebregts / Seebregts en Saey Advocaten, Tom de Boer and Tamara Buruma / Prakken d’Oliveira Human Rights Lawyers, Elpiniki Kolokatsi / Kolokatsi Advocaten, Bart Nooitgedagt / De Roos en Pen Advocaten and Jeffrey Jordan / Jordan Law.
