Canon 954

1. A vote is null, unless it is: (1) free; therefore, a vote

is invalid if an elector has been coerced directly or indirectly

by grave fear or by fraud to vote for a certain person or many

persons disjunctively; (2) secret, certain, absolute, and determinate, any contrary custom being reprobated. 2. Conditions

appended to a vote prior to the election are to be considered as

not having been appended.
