Hamdan v Callanan; Younan v Callanan

The appeals in Hamdan v Callanan and Younan v Callanan involved the applicants seeking a statutory order of review against the respondent's decision to issue attendance notices under the Crime and Misconduct Act 2001 (Qld). The applicants, who were suspects in a murder investigation, argued that the statute should not curtail common law rights unless expressly authorised. They also contended that the privilege against self-incrimination should not be abrogated for uncharged suspects. The primary judge dismissed the applicants' application, holding that the respondent's decision was authorised by the Act and did not involve an error of law.

The legal issues before the court were whether the primary judge erred in finding that the respondent's decision to issue attendance notices was authorised by section 82 of the Crime and Misconduct Act 2001 (Qld) and whether the primary judge erred in finding that the respondent's decision did not involve an error of law. The applicants argued that the statute did not authorise the abrogation of the common law privilege against self-incrimination for uncharged suspects. The court needed to determine the extent to which the statutory powers authorised by section 82 of the Act could be exercised without contravening common law rights.

The court found that the primary judge did not err in his conclusions. The court held that the respondent's decision to issue the attendance notices was authorised by the Act and did not involve an error of law. The court held that the statutory powers under section 82 of the Crime and Misconduct Act 2001 (Qld) were broad and could be exercised in a manner that might otherwise infringe common law rights, provided it was done in accordance with the Act. The court further held that the applicants' arguments about the abrogation of the privilege against self-incrimination for uncharged suspects were not supported by the text, context, or purpose of the Act.

The appeal was dismissed with costs.
