Corfield v Police

The matter before the court was an appeal against a conviction by Corfield, who had been found guilty of indecent assault. The case involved a dispute regarding the conduct of the prosecution and whether it had deprived Corfield of a fair trial. Corfield argued that the prosecution had failed to call a witness, Ms Mansell, whose testimony could have supported his defence and undermined the complainant’s evidence. This failure allegedly constituted a miscarriage of justice.

The central legal issues were whether the prosecution’s failure to call Ms Mansell constituted a breach of the principles of natural justice and whether such a breach had resulted in a miscarriage of justice that warranted a retrial. The court had to consider the extent to which the uncalled witness's testimony could have influenced the outcome of the trial and whether this failure amounted to a substantial injustice that could not be remedied by any other means.

The court found that Ms Mansell's evidence had the potential to significantly impact the trial’s outcome by casting doubt on the complainant's testimony. Given the possibility that this evidence could have led to a different verdict, the court concluded that the prosecution's failure to call Ms Mansell was a breach of natural justice. This breach was substantial enough to warrant a retrial to ensure Corfield received a fair trial. The court held that the failure to call Ms Mansell deprived Corfield of a fair trial and that this miscarriage of justice could not be rectified by any other means.

Accordingly, the appeal was allowed, the verdict of guilty was set aside, and the sentence of imprisonment was quashed. The court ordered that Corfield be retried before another magistrate, ensuring that all legal principles were adhered to in the new trial.
