Election representatives   Each party and constituency association that wishes to nominate a presidential candidate must have an election representative and each election representative must have a deputy.   A party election representative can not act as an election representative for another party. A constituency association representative can not act as an election representative for a party or another constituency association. A party representative or a constituency association election representative can not be a member or a deputy member of an electoral district committee or the central election committee.   A person authorized in writing by the party or constituency association election representative may submit an application, a notice or a correction as referred to in this Act on the representative’s behalf. What is provided in this Act on party or constituency association election representatives applies, as appropriate, to the deputy election representative.    A party and a constituency association must report the name and contact information of their election representative and deputy election representative to the Helsinki electoral district committee by the 48th day prior to polling day.
