Once you have decided that a nomination paper or home address is valid, it cannot be challenged during the election, although it may be challenged after the election through an election petition.1
If a nomination is determined to be invalid you must:2
state this on the nomination form
write the reasons for rejection on the form
sign the form
In both cases you must send a notice of the decision that a nomination form is valid or invalid to each candidate at their home address.3
This should be done as soon as practicable after your decision has been made.
