Invalidity of a ballot 

A ballot is invalid, if the ballot envelope contains something else or more than oneballot;

1)  a marking concerning the voter or a candidate or another inappropriate marking has been made on the ballot envelope; (247/2002)

2)  something other than a ballot printed by the Ministry of Justice has been used as the ballot;

3)  the ballot has not been stamped;

4)  the candidate number has been written so that it is not completely clear which candidate the vote was cast for;

5)  the voter's name or a distinctive mark or some other inappropriate marking has been made on the ballot;

6)  the ballot has, in parliamentary elections, been used to vote for a candidate who has been nominated as a candidate in two or more electoral districts.

Such a marking made on the ballot that only clarifies which candidate the voter has intended to vote for is not considered inappropriate.
