Crocker v The Queen

In *Crocker v The Queen*, the appellant, Crocker, was convicted of murder in the Supreme Court of Queensland. The appeal concerned the trial judge's directions to the jury regarding the defence of provocation.

The central legal issue before the High Court of Australia was whether the trial judge had erred in law by failing to adequately direct the jury on the subjective element of provocation, specifically concerning the appellant's state of mind and whether the provocation was such as to cause an ordinary person to lose self-control. The High Court also considered whether the jury had been properly instructed on the concept of cumulative provocation.

Kiefel and Bell JJ held that the trial judge's directions were insufficient. They explained that provocation requires a loss of self-control by the accused, which must be a consequence of the provocation. The jury must be satisfied that the provocation was such as to cause an ordinary person to lose self-control, and that the accused did, in fact, lose self-control. The judges emphasised that the jury must consider the cumulative effect of any acts of provocation, rather than treating each incident in isolation. The appeal was allowed, and a new trial was ordered.
