The final judgment in your case must be based on evidence. The prosecution must gather enough evidence to prove your guilt to the court.
There are many different types of evidence: written documents, video or audio recordings, data files, witness statements, the statements of an expert or other competent institution, as well as physical evidence.
You are also allowed to present your evidence and call your witnesses to the court. You must have an equal opportunity with the prosecution to present your evidence.
Evidence presented to the court must be relevant to your case and obtained legally. Evidence obtained by torture or threats to life or health to you or any other person cannot be used in court.
Your right to a fair trial might be violated if these requirements are not followed.
