Lynn v State of New South Wales

The appeal concerned an application by Lynn against the State of New South Wales regarding a continuing detention order. The primary dispute revolved around whether Lynn's conviction for manslaughter on the basis of excessive self-defence constituted a "serious violence offence" for the purposes of the relevant legislation. The appeal was heard by Basten, Leeming, and White JJA in the Court of Appeal of New South Wales.

The court was required to determine several legal issues. These included whether the conviction for manslaughter, arising from excessive self-defence, qualified as a "serious violence offence" under the relevant statutory provisions. Additionally, the court considered alleged errors in the making of the continuing detention order, specifically concerning the omission of a commencement date. Further grounds of appeal related to alleged inaccuracies in Lynn's criminal record, errors in submissions made to the primary judge, and purported mistakes in summaries provided to expert witnesses, as well as an alleged error in the assessment of risk.

The Court of Appeal dismissed the appeal. The reasoning of the court, though not detailed in the provided text, ultimately led to the conclusion that the grounds of appeal were not made out. The court found no error in the primary judge's determination that the conviction for manslaughter on the basis of excessive self-defence was a serious violence offence, nor were there sufficient grounds to overturn the continuing detention order based on the other alleged errors. The appeal was therefore dismissed.
