Cran v State of New South Wales

The Court of Appeal of New South Wales considered an appeal by Mr Cran against the State of New South Wales. Mr Cran alleged that he suffered post-traumatic stress disorder as a result of his prolonged incarceration, which he contended was caused by the failure of the Police and the Director of Public Prosecutions (DPP) to utilise established fast-track arrangements for laboratory processing of drug detection evidence.

The central legal issues before the court were whether the Police owed Mr Cran a duty of care in relation to the processing of evidence that led to his prolonged incarceration, and to what extent the Police and the DPP were immune from liability for actions taken in the course of their duties, particularly concerning court proceedings and the application of prosecutorial guidelines.

The court reasoned that the duty of care owed by the Police to a prisoner in Mr Cran's circumstances did not extend to the specific manner in which they conducted their investigation and processed evidence, especially where such actions were part of the pre-prosecution phase. Furthermore, the court affirmed that the DPP enjoys immunity from suit in relation to decisions made in the exercise of their prosecutorial discretion, including decisions concerning the conduct of criminal proceedings. The court found that the alleged failure to invoke fast-track arrangements did not fall outside the scope of this immunity.

The appeal was dismissed, and no order was made as to costs.
