Lipohar v The Queen - Winfield v The Queen

The High Court of Australia considered appeals by Lipohar and Winfield against their convictions for conspiracy to import a commercial quantity of heroin. The appellants were convicted in the Supreme Court of New South Wales following a trial before Adams J and a jury. The central dispute revolved around the admissibility of certain evidence and the proper application of the law relating to conspiracy.

The primary legal issues before the High Court were whether the trial judge erred in admitting evidence of alleged admissions made by one of the co-conspirators, Mr. Vella, and whether the jury directions on the elements of conspiracy were adequate. Specifically, the court had to determine if Vella's alleged admissions, made after the alleged conspiracy had ended, were admissible against Lipohar and Winfield, and if the jury was properly instructed on the requirement for an agreement between the accused and at least one other person to commit the unlawful act.

The High Court, in a joint judgment, held that the trial judge had erred in admitting Vella's alleged admissions against the appellants. The Court reiterated the principle that statements made by a co-conspirator after the termination of a conspiracy are generally inadmissible against other co-conspirators unless they fall within an exception, such as being part of the res gestae or constituting an admission by the party against whom they are sought to be used. In this instance, the admissions were not made in furtherance of the conspiracy, nor were they made by the appellants themselves. Furthermore, the Court found that the jury directions on the agreement element of conspiracy were insufficient, as they did not adequately convey that the agreement must be between the accused and at least one other person who is also a party to that agreement.

Consequently, the High Court allowed the appeals, quashed the convictions, and ordered new trials for both Lipohar and Winfield.
