Public authorities must nominate a mandatory notifier to report misconduct, including if they are not already listed in the law or if their principal officer position is vacant.

Mandatory notifiers must tell the Integrity Commission if they suspect a senior officer (like a commissioned police officer, senior executive, statutory office holder, MP, or council member) has committed misconduct, or if any public officer has committed serious misconduct; this applies even if they have confidentiality obligations and even if the person no longer works for that public authority.

Notifiers don't have to report misconduct if they know someone else already did; they also don't have to report if legal or disciplinary actions ended before the law started.

The Integrity Commission can investigate or report any mandatory notifier who fails to make a required notification.

The Integrity Commission can demand reports on actions taken by a public authority; it can also give advice on how to run an investigation.

Public authorities must stop their own investigations if the Integrity Commission takes over and tells them to stop.

Public authorities must tell the Integrity Commission in writing who their mandatory notifier is, or if a nomination is cancelled. They must also tell the Commission the outcome of any internal investigations into reported misconduct.
