Each participating club with 10 entries per session has to provide one certified official (carry current credentials). Teams with more than 10 entries, including relay entries, in one session must provide a second certified official. For every official that has not been provided, an additional fee of 40,00 € will be charged towards the respective club. In case the host provides uniforms for officials, those have to be worn (property of the sponsor of the host) [DSVSectionVI–§ 16 Official Clothing]. The uniform must be returned without question at the end of the meet. In case of loss or entrainment, the costs incurred will be charged to the club.
