Registration in text form using the registration form online, by e-mail, fax or letter is a prerequisite for participation. The participation fee includes lunch, refreshments and drinks in the breaks, a visit to the evening reception and, in addition to the conference proceedings, a subscription to the magazine Behörden Spiegel for one year, so that you will be kept informed about further developments regarding the topics of the conference. The subscription will automatically be renewed for free. This you can contradict at any time by an informal message. Upon receipt of your registration you will receive a confirmation of receipt followed by a registration confirmation by e-mail and an invoice by post. If you cancel the registration until two weeks before the start of the event, a processing fee of 50% of the participation fee will be charged. Later or if the participants do not participate, the entire participation fee will be charged. It is of course possible to send replacements for registered participants. Participants who are considered consumers will find the right of withdrawal here.
