What is the best way to handle a police summons?

No one is required to appear in response to a police summons.

This applies not only to those accused of a crime but also to witnesses.

Rules for the accused when summoned by the police

As an accused person, you have the right to remain silent. You are only required to provide basic personal information (see Arrest).

‍You should never give a statement to the police without legal counsel.

The lawyer is also entitled to inspect the investigation files.

Rules for witnesses summoned by the police

A witness is only required to comply with a summons from the public prosecutor's office or the court.

As a witness, you are generally required to provide information. However, you may have the right to refuse to testify as a spouse, etc., or because you could incriminate yourself.

You should also consult with a lawyer about this beforehand.
