Police v Baker

In Police v Baker, the appellant, the South Australian Police, filed a notice of appeal against the respondent's acquittal on 16 March 2015. The respondent was initially charged with assault under section 20 of the Criminal Law Consolidation Act 1935, with the key issue being whether the complainant, DF, consented to the alleged assault. The appeal was grounded on two main arguments: first, that the Magistrate erred in determining that the respondent's evidence of DF's lack of consent was so unreliable that no reasonable tribunal could convict based on it, and second, that the Magistrate erred in finding reasonable doubt about whether DF consented to the assault. The appellant sought an order to set aside the respondent's acquittal and remit the case for a retrial before a different Magistrate.

The court noted the established judicial approach to prosecution appeals against acquittals, which requires a cautious and exceptional standard of review. This approach recognises the inherent difficulties appellate courts face in assessing witness credibility and the potential risk of double jeopardy for the respondent. The court emphasised that such appeals are allowed only in the clearest and most compelling circumstances to correct manifest errors. In this case, the appeal hinged on whether the Magistrate's decision to acquit was plainly wrong based on the evidence presented.

Upon reviewing the evidence, the court found that the Magistrate did not make an explicit finding of no case to answer but instead concluded that the prosecution's evidence was so lacking in weight and reliability that no reasonable tribunal could safely convict. The Magistrate's decision appeared to focus primarily on the absence of DF and the perceived unlikelihood of consent to the described assault. The court found that the Magistrate did not provide adequate reasons for his conclusion and that the evidence did not lack reliability or weight in terms of the primary facts observed by Sergeant Stephen. The court further noted that the Magistrate failed to consider several relevant factors, such as the inherent unlikelihood of consent to being struck in the manner described, the force of the blow, and the circumstances under which the incident occurred.

Ultimately, the court determined that the Magistrate's decision to acquit was plainly wrong. The court found that the evidence was sufficient for a reasonable tribunal to convict, and the Magistrate's exclusion of relevant factors without proper justification was a manifest error. Consequently, the appeal was allowed, the respondent's acquittal was set aside, and the matter was remitted for a rehearing before a different Magistrate.
