Although there are no definitive signs of fraud, you should ensure that you have mechanisms in place to identify suspicious absent vote applications. Applications for absent votes do not have to be taken at face value. You can require additional information where necessary, such as an attestation, to verify the identity of an applicant.
The following could, depending on the context of the local area and the specific circumstances surrounding any application or applications, be indicators of possible fraud:
a number of application forms completed in the same handwriting.
unusually large numbers of absent vote applications in a particular area
unusually large numbers of postal and postal proxy redirections to one particular property or properties
unusually large numbers of proxy attestations
unusually large numbers of signature waiver requests. For example:
large numbers of applications assisted or signed by one person with no plausible explanation
large numbers of applications from one street or area with no plausible explanation
signature and/or date of birth provided on the application form is inconsistent with data that you already hold
acknowledgements or confirmation notices returned as undelivered
You should put in place mechanisms that will help to identify suspicious absent vote applications including:
training for office staff on what to look out for
regular data reviews to identify patterns
considering how to share data about patterns of applications with local political parties and elected representatives to improve transparency and confidence, so that they can help identify any applications which might be suspicious.
