R v Mitchell

In the matter of R v Mitchell, the defendant, Rigney, sought an order under rule 49(1) of the Supreme Court Criminal Rules 2014 (SA) to exclude items seized during a police search of 54 Ryan Street, Moonta. The seized items included a black iPhone belonging to the deceased, which is critical evidence in the prosecution case. Rigney argued that the search conducted by Detective Brevet Sergeant Franz under a General Search Warrant (GSW) was unlawful because Franz lacked "reasonable cause to suspect" as required by s 67 of the Summary Offences Act 1953 (SA). The primary legal issue was whether Franz had a reasonable suspicion at the time of the search, and whether the evidence obtained should be excluded as unfair or improperly obtained.

The court examined the criteria for a reasonable suspicion, drawing from previous cases which establish that a suspicion involves a state of conjecture or surmise where proof is lacking, and must be based on a rational connection between the supporting material and the suspicion. The court assessed whether Franz's suspicion was objectively reasonable by considering the information available to him at the time of the search. Franz testified that he relied on information suggesting the presence of stolen goods or items that may afford evidence of an offence. However, Franz's testimony was inconsistent, as he initially believed there was only one search on 26 October 2018, but later admitted there were two separate searches, with the second occurring on 7 November 2018. Despite this confusion, the court found that Franz did possess sufficient information to form a reasonable suspicion at the time of the first search.

The court dismissed Rigney's application to exclude the evidence, concluding that the police search was lawful. The reasoning hinged on the objective assessment of Franz's knowledge and the information he had at the time of the search, which sufficiently supported a reasonable suspicion. Consequently, the items seized during the search, including the iPhone, were deemed admissible in the prosecution case against Rigney.
