Both you and the state institution have an equal right to submit evidence to the court. The court must accept your evidence on the same terms and conditions as the evidence of the other party.
The court is not obliged to accept all the evidence that is proposed by you or the institution.
There are three important criteria which require that evidence is:
As a general rule, the evidence used in court has to be obtained lawfully. This means it has to be obtained according to procedures prescribed by law and that human rights must not be violated in the process of gathering the evidence. If certain evidence has been obtained in violation of your rights (such as the right to private life or secrecy of correspondence), it will the proceedings unfair.
In the court proceedings related to administrative offences the Code of Criminal Procedure applies subsidiary. This means that the court can also assess the reliability of the evidence. In assessing its reliability, the court can take into account the nature of the evidence (whether that is a photograph, document or witness testimony) and whether it is supported by other evidence in your case. All evidence is equally reliable when it is submitted. No evidence can be presumed to be more reliable than any other without individual assessment.
The court will only accept evidence that is relevant to the case. The court has the right to assess evidence and reject any which it considers to be irrelevant to the case.
