Since equal suffrage guarantees that each voter shall have the same number of votes, this category includes measures that prevent fraudulent or erroneous votes from being recorded.
4) Only votes cast by eligible voters shall be counted, and only the
permitted number of votes for that voter. (5a, 94) Note: this will
require special attention where voters are allowed to cast provisional
votes.
5) An authentication system shall exist to distinguish eligible voters from
others, and those who have successfully cast votes from those who have not.
Note: this may require special attention where multiple voting channels exist,
and where voter registers may not be up-to-date. (5b, 6, 41, 44, 82)
6) Votes shall not be recorded outside the polling period. However, provision
shall be made for latency in voting channels. (91, 96)
