When contacted by the police, communication is often conducted in such a way that it may seem as though a citizen is obligated to participate in questioning. However, this is not the case—appearing at the police station and participating in questioning is voluntary, with one exception: appearing at the police station and participating in questioning is mandatory only when the police summon a citizen regarding the activation of a mobile or telephone number. Therefore, when contacted by the police, you should first clarify the reason for your summons. Do not immediately agree to appear; inform the police officer that you need time to consider, and once you have decided whether you wish to participate in questioning, you will notify the police of your position. It is important to note that if you do not go to the police for questioning, you may later be summoned to court for testimony, where your appearance will be mandatory. You may wonder: if I might ultimately be required to provide information to the police, why not agree to participate in questioning from the outset? The answer is that your rights may be violated during police questioning, which is virtually impossible in court. Ultimately, our advice is that if you agree to participate in police questioning, you should definitely use the services of a lawyer to ensure your rights are fully protected. Remember, the information you provide to the police is of utmost importance, as the fate of a criminal case may be determined based on this information.
