The appellant, Brian Boese, appealed a trial judge's decision that his brother Bruce's will was formally valid under the Succession Law Reform Act.
The central issue was whether the respondent, Brenda Bayford, had proven the formal validity of a 2013 will (Version 2), which she claimed to have found after Bruce's death.
The appellant argued that the trial judge misapprehended expert handwriting evidence, which indicated that Bruce's signatures on two versions of the will (one unwitnessed, one witnessed) were identical copies, suggesting one was reproduced from the other.
The Court of Appeal found that the trial judge made a palpable and overriding error by misunderstanding the significance of the expert evidence and its implications for the appellant's theory of the case, particularly regarding the missing original unwitnessed will and inconsistencies in the respondent's testimony.
The court also rejected the respondent's motion to admit fresh evidence.
