#court fee

Is it lawful to collect a court fee for filing an appeal or cassation complaint against a court ruling on the refusal to grant an application for judicial control over the execution of court decisions by public authorities?

I want to know if there are cases where it is possible to file a lawsuit without paying a court fee? What conditions must be met so that the court fee is not paid? Are there any categories of citizens or cases to which this rule applies?

Do I have the right not to pay court fees if I am a participant in hostilities and file a lawsuit regarding the violation of my rights?
