WA Police is standing by its handling of a domestic violence case that has drawn fierce criticism, centred on concerns that a magistrate did not view available footage before sentencing the attacker to 15 months.

The case has sparked significant public and legal scrutiny, with the relatively short sentence fuelling debate about how evidence was presented and considered during proceedings.

Police have moved to defend the conduct of officers involved, pushing back against suggestions that the case was mishandled ahead of or during the court process.

The matter raises broader questions about the management of domestic violence cases within the WA justice system, particularly around the use of video evidence at the sentencing stage.
