Judges at a revolving door

Challenge: What is it and how does it work in the judicial system?

Challenge is an important legal instrument in the administration of justice that allows the impartiality of a judge to be questioned. It is a procedure that ensures that a judge who may be biased is replaced by another judge. A challenge request can be submitted by a party or their solicitor; this can be done before, during or after the hearing, at the request of the party handling the case. In this article, we explain exactly what challenge entails, under what circumstances a challenge request can be submitted, how the challenge chamber decides and what the consequences are for the handling of a case. The challenge procedure is regulated in Articles 36 to 41 of the Code of Civil Procedure, which form the legal basis for this procedure. These articles provide a clear structure for submitting and handling a challenge request. A challenge can be requested before, during or after the hearing, at the request of the party bringing a case before the court. The challenge procedure is therefore firmly anchored in legislation to guarantee the impartiality of the judiciary.

Introduction

Challenge is an important part of the Dutch legal system, whereby a party in a court case has the option of challenging a judge if there are doubts about his impartiality. The judge plays a central role in the administration of justice, and it is of great importance that he performs his work independently and without bias. When circumstances arise that cast doubt on the impartiality of the judge, recusal offers a formal way to have another judge hear the case. In this article, we discuss the role of the judge, the recusal procedure, and the disqualification of judges. We also discuss the steps that can be taken to recuse a judge and the consequences this has for the handling of a court case.

The Role of the Judge

Within the judiciary, the judge has the task of administering justice in an independent and impartial manner. This means that the judge must be guided by the law and the facts of the case, without being influenced by personal interests or relationships. If, during or after the hearing, facts and circumstances come to light that could compromise the impartiality of the court, a party may submit a challenge request. This request is intended to ensure that the case is heard fairly and that the impartiality of the judge is not compromised. It is essential that the judge always avoids the appearance of partiality in order to maintain confidence in the administration of justice. By submitting a challenge request, parties can express their concerns about the impartiality of the judge and, if necessary, have them reviewed by an independent challenge chamber.

The Judge and the Law

The judge is bound by the law and the rules of jurisprudence. This means that a judge must strictly adhere to established procedures, including the rules governing recusal and disqualification. The law determines when and on what grounds a judge can be challenged or recuse himself. If a party believes that the judge is not impartial, it can submit a challenge request. This request is then dealt with by the challenge chamber, which independently assesses whether there are circumstances that jeopardise the impartiality of the judge. In this way, the judiciary ensures that every case is heard by a judge who meets the requirements of independence and impartiality. The challenge procedure is therefore an important instrument for protecting confidence in the judiciary.

What is recusal?

Challenge is a request to have a judge replaced by another judge because there are facts or circumstances that could compromise the judge’s impartiality. In Dutch, ‘wraking’ refers to a legal concept whereby a party requests the recusal of a judge or other official on the grounds of possible bias or conflict of interest. This means that if there is doubt about the impartiality of the judge, a challenge can be filed to prevent the judge from hearing a case where there is an appearance of partiality. In Dutch law, ‘wraking’ is a specific legal concept that differs from the English word ‘wracking,’ which refers to destruction or emotional torment. It is important not to confuse these terms because of their different meanings. The Dutch term ‘wraking’ is therefore clearly distinguishable from the English word ‘wracking’, which refers to destruction or emotional torment, and emphasises the legal context in which it is used.

The purpose of recusal is to ensure the integrity and trust in the administration of justice. If an applicant believes that the judge is biased or that there is an appearance of bias, he or she may file a recusal request to recuse the judge, for example, if he or she finds the judge to be biased. This ensures that the administration of justice remains fair and impartial. The party’s request must be submitted in writing to the court. Every party in legal proceedings has the right to an impartial judge, which is a fundamental principle of the administration of justice.

When can a challenge be filed?

A challenge can be filed if there are certain facts or circumstances that cast doubt on the impartiality of the judge. This may be the case, for example, if:

  • The judge was previously involved in the case or has an interest in the outcome.
  • There are personal relationships between the judge and one of the parties.
  • The judge has expressed himself in a manner that creates the appearance of partiality.
  • New facts or circumstances have come to light that could affect impartiality.
  • The judge’s previous relationship with a party or previous rulings may influence the perception of fairness.

The challenge can be submitted during the hearing, but also after the hearing. The procedure is initiated at the request of the party that has doubts about the impartiality. It is important that this is done as soon as possible once the applicant is aware of the facts and circumstances that call the impartiality of the judge into question. However, a challenge request may also be submitted prior to the hearing, depending on when the facts or circumstances become known. This means that a challenge request may be submitted at any time during the proceedings, as long as the grounds for the request are made clear. The request must be submitted in writing and the grounds for the request must be explicitly stated. Submitting the request in writing is essential in order to substantiate the reasons for the alleged partiality of the judge. The fact that a challenge can be submitted before, during and after the hearing offers parties flexibility to protect their rights.

If the judge does not contest the challenge, he or she will be replaced immediately without the intervention of the challenge chamber.

Investigation by the examining magistrate

The examining magistrate plays a specific role in the challenge and recusal process. He ensures that the procedure surrounding the challenge request is followed correctly and that the rights of all parties involved are respected. In some cases, the examining magistrate may be asked to investigate the facts and circumstances that gave rise to the challenge request. Based on his findings, the examining magistrate may advise the challenge chamber on whether it is desirable to challenge the judge. Through this role, the examining magistrate contributes to the careful and transparent handling of the challenge request, taking into account all relevant facts and circumstances.

How is a challenge request handled?

When a challenge request is submitted, the challenge chamber decides on the request. The challenge chamber is a special chamber within the judiciary that assesses whether there are indeed facts or circumstances that could make the judge biased or whether there is an appearance of bias. It is possible to challenge a member of the challenge chamber if there are doubts about their impartiality. The judge against whom the challenge is directed may not participate in the hearing of the request, in order to guarantee the objectivity of the procedure. This ensures that the assessment of the request is completely independent. Excluding the judge concerned from the hearing of the request is a crucial step in guaranteeing the integrity of the procedure.

The challenge chamber decides on the challenge request as soon as possible, because it is important that the hearing of the case is not unnecessarily delayed. The parties are given the opportunity to explain their position before a decision is made. If the challenge chamber declares the request well-founded, the challenged judge is replaced by another judge who will continue to hear the case. It is essential that the challenge chamber acts quickly to ensure the progress of the proceedings, as a swift decision is crucial for the efficient administration of justice. The speed of the decision is of great importance in order to prevent unnecessary delays in the proceedings.

Consequences of challenge for the handling of the case

If a challenge is granted, this has direct consequences for the handling of the case. The original judge is replaced by another judge, thereby guaranteeing the impartiality of the judiciary. This may mean that the case has to be re-examined by the new judge to ensure that the facts and circumstances are properly assessed.

The challenge request therefore ensures that the administration of justice remains transparent and fair, and that parties can trust that their case will be heard by an impartial judge.

Appeal against the decision of the challenge chamber

In all areas of law – civil, administrative, criminal, and before the Council for the Administration of Criminal Justice and Youth Protection – no appeal, cassation, or any other legal remedy is available against a decision of the chamber handling recusal requests. This follows directly from the applicable statutory provisions (Article 39(5) Code of Civil Procedure, Article 8:18(5) General Administrative Law Act, Article 515(5) Code of Criminal Procedure, and Article 31(9) Establishment Act).

Moreover, in its judgment of 14 June 2024 (ECLI:NL:HR:2024:918), the Supreme Court expressly held that even recourse to appeal or cassation on so-called “through-breaking grounds” (doorbrekingsgronden) is excluded. This means that no remedy is available, even in the most exceptional of circumstances.

Any objections concerning the (im)partiality of the judge can only be raised in the legal remedy against the final judgment in the main proceedings, for instance by invoking a violation of Article 6 ECHR (right to a fair trial).

More information about recusal

For more information about recusal and the procedure surrounding the recusal request, those involved can consult the case law. It is important to know that submitting a recusal request is a serious measure that should only be used if there are actual facts or circumstances that could affect the impartiality of the judge.

The correct application of challenge ensures the impartiality of the judge and maintains confidence in the judiciary. If you are considering submitting a challenge request, make sure you do so on the basis of valid facts and circumstances and as soon as possible after you become aware of them.


Challenges play a crucial role in guaranteeing impartiality within the administration of justice. Challenging a judge can prevent a case from being heard by a judge who is found to be biased or who appears to be biased. This contributes to a fair and transparent trial, in which confidence in the administration of justice is maintained.
