If you believe that rules overseen by the Human Environment and Transport Inspectorate (ILT) are being broken, you can submit a handhavingsverzoek (enforcement request). With this request, you ask the ILT to take action against the possible violation you have identified. Your enforcement request must meet certain conditions.

You must be an interested party and cannot remain anonymous

If you want to submit an enforcement request, then you must be an interested party, within the meaning of Article 1:2 of the Algemene wet bestuursrecht (General Administrative Law Act, in Dutch). This means you have an objective, personal, own, direct and current interest in the situation. The ILT needs to know who you are to assess this. The ILT does not process anonymous enforcement requests.

If you submit an enforcement request, you enter a legal procedure. Your details, name, address and place of residence may be shared with the suspected offender or offenders. If you do not want this, you cannot submit an enforcement request to the ILT. You can instead ask a question or notify the ILT. If you submit a question or notification, you can state that your details must not be shared with the offender. You do not need to be an interested party in that case.

How to submit an enforcement request

If you want to submit an enforcement request, you must do so in writing:

  • If possible, use the contact form. State clearly in the subject field that you are submitting an enforcement request. If you do not do this, your message will be treated as a regular question.
  • You can also submit your enforcement request by letter. Send your signed request to:
    Human Environment and Transport Inspectorate (ILT)
    Postbus 16191
    2500 BD Den Haag
    the Netherlands
  • It is not possible to submit an enforcement request by telephone.

Make sure to always indicate the following in your enforcement request:

  • The type of violation in question and who is committing it. Describe clearly what is happening and explain how you know about it. If you have proof, please include it.
  • The fact that it is an enforcement request. Explain what you want the ILT to do and what should happen according to you. Describe your direct personal interest in the situation or in resolving the violation.
  • Your name and address, the date on which you submit your enforcement request and your signature. Prepare a clear photo or scan of your signature (.jpg or .png) and send the file with the contact form.

After your enforcement request

The ILT will assess your enforcement request. There are 2 possible outcomes:

  • Your enforcement request is accepted. In this case, the ILT confirms that there is a violation, that it is allowed to take action and that there are no reasons not to act. You will receive a response within 8 weeks after the ILT receives your request. The ILT will inform the offender that it will take action.
  • Your enforcement request is rejected. In this case, the ILT cannot or is not allowed to act on the reported violation. This may be because the violation does not fall within the ILT’s remit or because you are not an interested party. There may also be other reasons, for example if no rules were actually broken. You will receive a response within 8 weeks after the ILT receives your request, including the reasons for the rejection.

The ILT does not handle individual airline compensation

If you want personal compensation from an airline for a delayed flight or denied boarding, you cannot submit an enforcement request through the ILT. A court has decided that the ILT is not authorised to act in such individual claims.
