The context of the AMPs regime is different. The AMPs regime is an administrative process, while the prosecution of offences falls into the criminal set of rules. Yes, there are many safeguards included in the AMPs regime, including an administrative review of the penalty and of the file from the Chief Electoral Officer, and of course, the Chief Electoral Officer's review decision could be reviewed by the Federal Court. The process is different. It's an administrative process rather than a criminal process, but yes, there are a lot of safeguards in place.
