It flows from the Rules and Regulations of Chancellery of the Sejm and a contract concerning the transfer of copyright, the right to use the logo depends on the nature of an event. In case the event is organised by an external body, a consent of the Chancellery of the Sejm is necessary. Such consent is not required when the logo is to be used in an undertaking organised by a committee of the Sejm. The consent is granted by the Chief of the Chancellery of the Sejm or a person authorised by him.
