An unfavourable judgment can be frustrating, particularly when a party believes the judge misunderstood the evidence. Housen v. Nikolaisen explains why an appeal requires more than asking another court to reach a different conclusion.

The case arose from a motor vehicle accident and a negligence claim involving a municipality. The Supreme Court of Canada examined the standards appellate courts apply when reviewing trial decisions.

Questions of law are generally reviewed for correctness. An appellate court can therefore intervene where the trial judge applied an incorrect legal rule.

Findings of fact receive greater deference. Intervention ordinarily requires a palpable and overriding error—an obvious error that affects the result. Questions involving the application of law to facts generally attract the same deferential standard unless a separate legal error can be identified.

The distinction recognizes the trial judge’s role in hearing the evidence and assessing witnesses. An appellate court does not ordinarily repeat that process merely because another interpretation of the evidence is possible.

What this could look like in practice

Imagine a hypothetical payment dispute in which the judge accepts one witness’s account over another’s. A disappointed party may feel strongly that the other witness should not have been believed. Preparing an appeal would require examining the reasons and record to identify the alleged error and explain its significance.

A different concern might arise if the judge used the wrong legal test to determine liability. That would call for an assessment focused on the legal rule applied and whether it affected the decision.

These examples show why an appeal review should begin with the judgment itself, rather than a general retelling of the dispute.

The takeaway

For an initial consultation, gather the reasons for judgment, the order, and the relevant court materials. Identify the specific passages you believe are wrong and explain why. That gives a lawyer a focused starting point for assessing potential grounds, the applicable review standard, and whether an appeal offers a practical path forward.
