Asgedom v R

The case of Asgedom v R was heard by Judge Harvey, involving a dispute concerning the admissibility of evidence, specifically an Excel spreadsheet created by Detective Traviss. The spreadsheet, which contained data from Ticketek, credit card companies, and police investigations, was tendered under s 133 of the Evidence Act 2006. The primary legal issues before the court were the admissibility of the spreadsheet as evidence and whether there was a basis for a stay of proceedings due to lack of disclosure. The court had to consider whether the presumption of reliability for computer-generated evidence applied and if it could be rebutted by the defence.

Judge Harvey addressed the legal issues by examining the presumption of reliability for computer-generated evidence under s 137 of the Evidence Act, which presumes that a machine, device, or technical process ordinarily operates as asserted unless proven otherwise. The judge concluded that once the Crown established how computerized transactions ordinarily work through the Ticketek website using credit cards, the presumption of reliability arose, and the onus shifted to the defence to provide evidence to rebut this presumption. The court noted that this would usually require expert evidence. The judge found that there was no basis for a stay of proceedings due to lack of disclosure or any other ground.

The reasoning of the court led to the conclusion that the spreadsheet was admissible as it complied with the requirements of s 133 of the Evidence Act, which allows for the summarisation and collation of large volumes of evidence into a manageable form. The spreadsheet made it possible to observe relationships between credit card numbers and transactions, and filter information to isolate details of various transactions. As a result, Judge Harvey admitted the spreadsheet as evidence and ruled that there was no basis for a stay of proceedings.

The final orders of the court were that the spreadsheet evidence was admissible and there was no basis for a stay of proceedings on any ground.
