Helton v Allen [1940] HCA 20

Helton v Allen [1940] HCA 20

The evidence was sufficient for a jury to infer Helton unlawfully killed Roche, but a mistrial occurred because the judge's directions to the jury inadequately reflected the gravity of the accusation, improperly emphasizing the ease with which a finding could be made on a slight preponderance of probabilities, rather than true reasonable satisfaction; further, Helton’s acquittal in the criminal trial did not bar the operation of the public policy rule excluding an unlawful killer from benefits under the will, nor was it conclusive or admissible in the civil proceeding.

Procedural Posture

Appeal (civil) / On Appeal From the Supreme Court of Queensland to the High Court of Australia

Legal Issues

  1. 1 Whether acquittal of murder in criminal proceedings bars application of public policy excluding a killer from benefit under the victim's will
  2. 2 Whether the evidence was sufficient to support the jury's finding of unlawful killing
  3. 3 Whether the trial judge misdirected the jury on the standard of proof required in civil proceedings alleging criminal conduct

Ratio Decidendi
