Invalid ballots

The provisions on invalid ballots are in section 85 of the Election Act. Grounds for invalidity are
1) the ballot envelope contains something else or more than one ballot paper
2) the ballot envelope has an unauthorised mark
3) something other than a ballot paper printed by the Ministry of Justice has been used as the ballot paper
4) the ballot paper has not been stamped
5) the candidate's number has been written unclearly
6) the elector's name or distinctive identification or some other inappropriate marking has been made on the ballot paper.

In addition to the above, statistics are compiled also on the number of empty ballots.
