Judgment Day

Manslaughter retrial turns on evidence admissibility

Background

Leanne Chrysilla Eatts was originally convicted of two counts of manslaughter after her two young sons drowned in the Ross River in Townsville in 2019. The Prosecution argued that Ms Eatts failed to properly supervise the children, which led them to reach the river unsupervised where they tragically drowned.

At the Trial, the Prosecution played part of a recorded phone call between Ms Eatts and the father of one of the children. During the phone call the father accused Ms Eatts of being negligent and responsible for the children’s deaths.

Grounds of Appeal

Ms Eatts appealed her conviction, arguing that the Trial Judge was wrong to allow part of that phone call to be played to the jury.

Findings

The Court of Appeal agreed with Ms Eatts and found that the portion of the phone call played to the jury was “highly charged and emotional” . It also contained accusations that were unfair and potentially misleading. The Court held that:

1. The phone call had no real probative value, meaning it did not help prove any important issue at Trial;
2. The prejudicial effect of the evidence substantially outweighed any probative value (i.e. playing that part of the phone call risked unfairly swaying the jury); and
3. The conversation included a false allegation (that the gate was open). There was no evidence at Trial that this was the true and may have misled the jury about the facts.

Due to the above, the Court of Appeal found that a miscarriage of justice had occurred.

The Court quashed the two manslaughter convictions and a retrial was ordered, which is set down for March 2026.

Significance and Implications

The decision illustrates the strong caution Courts should have to emotional or accusatory material that risks unfairly prejudicing a jury. Even if evidence is compelling, it must satisfy the balancing test of probative value vs prejudicial effect. That is, even if the material feels powerful, it cannot be admitted unless its probatibe value (i.e. it’s usefulness in proving something important) outweighs its prejudicial effect (i.e. the risk of unfair bias).

The judgment also underscores that evidence that is lacking in factual foundation (e.g. a false allegation that is not supported by any objective evidence) is dangerous to admit.

By ordering a retrial rather than an acquittal, the Court of Appeal made it clear that whilst the original trial was unfair, the Prosecution’s case still had enough potential merit to be heard again.
