Green v Sommerville

The High Court of Australia heard an appeal in *Green v Sommerville*. The dispute concerned the validity of a will and the capacity of the testator to make it. The primary issue was whether the testator, Mr. Sommerville, possessed the requisite testamentary capacity at the time he executed the will.

The Court was required to determine whether the evidence established that Mr. Sommerville understood the nature of the testamentary act and its effect, that he was aware of the extent of his property, and that he appreciated the claims of those who might expect to benefit from his will. The Court also considered the legal standard for testamentary capacity, particularly in circumstances where the testator may have suffered from a mental disorder.

The High Court applied the principles established in *Banks v Goodfellow* (1870) LR 5 QB 549, which require a testator to have a sound mind, memory, and understanding. The Court found that while Mr. Sommerville had experienced periods of mental disturbance, the evidence demonstrated that at the time of executing the will, he had a sufficient understanding of the matters relevant to making a will. The Court emphasised that a testator need not be free from all mental infirmity, but must possess the specific capacities outlined in *Banks v Goodfellow*.

The appeal was dismissed, and the will was held to be valid.
