Simmons & Simmons

The appeal in Simmons & Simmons involved a dispute between the parties regarding the living arrangements of their three daughters following their separation and subsequent allegations of family violence and sexual abuse against the father by the eldest child. The case was heard by the Family Court of Australia, with the appeal being brought before a Full Court. The key legal issues that the Full Court had to resolve were whether the primary judge correctly admitted and considered relevant evidence, particularly the report from the eldest child's treating psychologist, and whether the orders made by the primary judge were in the best interests of the children.

The Full Court found that the primary judge erred in excluding the report from the eldest child's treating psychologist, which provided an alternative explanation for the child's problematic behavior. The Court emphasised that relevant evidence, even if only slightly probative, is generally admissible. The Full Court reasoned that the primary judge's exclusion of this report, which could have rationally affected the assessment of the probability of the existence of a fact in issue, was a significant error. The Court also considered the principles outlined in Annesley & Pembleton and CDJ v VAJ, which require that any judicial decision affecting a child's welfare must be made with a broad appreciation of the implications for the child’s welfare. The Full Court held that the primary judge’s orders were not in the best interests of the children, given the significant impact they would have on the children’s lives.

The Full Court set aside the orders made by the primary judge and remitted the case back to the primary judge for rehearing. The Court directed that the primary judge should give consideration to the excluded report and other relevant evidence, and make new orders that are in the best interests of the children.
