R v Martin

The appellant, Martin, was convicted of murder and sentenced to life imprisonment. He brought a second appeal to the Court of Appeal, arguing that his conviction was procured by impropriety or fraud. Martin claimed that the trial judge had been biased and that the prosecution had withheld crucial evidence. The court was required to decide whether the Grierson principle, which provides that a conviction procured by impropriety or fraud is void, applied in this case, and whether it was displaced by sections 58 and 59 of the Constitution of Queensland Act 2001, which provide that the Court of Appeal may not review the conviction or sentence unless there has been a miscarriage of justice.

The court found that the trial judge had not been biased and that the prosecution had not withheld crucial evidence. The court held that the Grierson principle did not apply because Martin had not shown that the trial judge’s conduct had influenced the outcome of the trial. The court also held that sections 58 and 59 of the Constitution of Queensland Act 2001 did not override the Criminal Code or the Grierson principle because they were intended to ensure that the Court of Appeal did not interfere with the trial judge’s assessment of the evidence.

The applications were dismissed. The court held that Martin had not shown that his conviction was procured by impropriety or fraud, and that the trial judge had not been biased or that the prosecution had withheld crucial evidence. The court also held that sections 58 and 59 of the Constitution of Queensland Act 2001 did not override the Criminal Code or the Grierson principle.
