Diamond v Massin

The dispute in Diamond v Massin centred around the validity of a will executed by Lucienne Suzanne Massin on 9 March 2000. The case was heard in the Supreme Court of Queensland. The primary issue for determination was whether the testatrix possessed the requisite testamentary capacity, specifically, soundness of mind, memory and understanding, at the time of executing the will. A central point of contention was the English proficiency of the testatrix, as there was conflicting evidence regarding her command of the English language.

The court had to consider whether the testatrix knew, understood and approved of the contents of the will, despite the discrepancies in her English language abilities. This involved an assessment of the credibility and weight of the evidence presented, particularly focusing on the testatrix's capacity to comprehend and instruct the preparation of the will in English. The court also examined the failure of one co-executor of the will, who was reasonably expected to be called as a witness, to provide evidence, and whether an adverse inference should be drawn from this omission.

After weighing all the evidence, the Supreme Court of Queensland concluded that the will executed by Lucienne Suzanne Massin was valid. The court found that the testatrix had testamentary capacity and had understood and approved the contents of the will. The court further held that despite the conflicting evidence regarding her English proficiency, the testatrix was capable of instructing the preparation of the will in English and had the requisite knowledge and understanding of its contents. The court did not draw an adverse inference from the failure of the co-executor to give evidence.

The final order of the court was that the will executed on 9 March 2000 by Lucienne Suzanne Massin is valid.
