Standard of Appellate Review

General Principles

The "standard of review" represents the "margin or tolerance" of "deviation" in the judge's findings.[1]

A court of appeal should never set aside a conviction merely on the basis of a different view of the evidence. It is not the duty of the appellate court to re-try the case.[2]

Meaning of Deference on Review

The concept of deference by an appellate court is "aimed at recognizing and upholding the division of labour (adjudicative authority) as between first instance and appellate ... courts."[3]

Categories

All reviewable decisions made by a judge can be seen as answering one of three categories of questions:[4]

  1. questions of law: what is the correct legal test to be applied
  2. questions of fact: what took place between the parties
  3. questions of mixed law and fact: whether the facts satisfy the correct legal tests[5]
Questions of law and questions of fact

All questions of law are to be reviewed on a standard of "correctness."[6]

A question of law inquire into the "correct legal test" to be applied for a particular legal issue or the "the application of a legal standard" to facts.[7] This also includes the interpretation of a legal standard[8] and the application of a standard to settled facts.[9] However, where the facts are in dispute, it is most likely a question of mixed fact and law.[10]

Questions of fact

All questions of fact are reviewed on a standard of "palpable and overriding error".

All findings of facts are questions of fact.[11]

The standard of "palpable and overriding error have been broken down into two components. "Palpable" means that the error is obvious. The logic must be obviously flawed. This would include findings of fact without any evidence or logical errors.[12] "Overriding" means that the error "affects the outcome of the case". That is to say, but for one or more palpable errors, the outcome would have been different.[13]

Questions of mixed fact and law

Where the question is neither purely a question of law or question of fact, then it is considered a question of "questions of mixed law and fact".

Exercises of Discretion

The appellate court owes deference to exercises of discretion. However, where the exercise is unreasonable, then no deference is required.[14]

It is a convenient way to describe the view-finder, the lens, through which we, as appellate judges examine the error alleged to have occurred in the court below.")

The Court of Appeal must remember that it is neither its duty nor its function to re-try cases — its function is one of review.")

Deference relates to fact finding and to exercises of discretion. By comparison, the rule of law requires the appeal court to make a de novo evaluation of whether the flaws in the trial process did in actuality occasion an unfair trial and consequently a miscarriage of justice regardless of innocent intentions: ...")

Questions of Law

Questions of Fact

Findings of fact are given deference on appeal.[1] The court of appeal should not substitute their own view of the evidence with the findings of facts of the trial judge.[2] Findings of fact, whether adjudicative, social, or legislative are reviewed on a standard of "palpable and overriding error."[3]

Where a palpable and overriding error has been found, the judge may intervene with its view of the evidence as well as draw inferences based on that evidence.[4]

The following have been found to be questions of fact and so reviewable on the palpable and overriding error:

  • findings of fact[5], including:
    • findings of fact relating to Charter breaches[6]
  • Findings of credibility[7]
  • whether an inference can be drawn from established facts[8]
  • whether an officer had an honest subjective belief in the existence of a ground[9]
  • assessing the weight given to an item of evidence or evidence as a whole in determining whether it meets the standard of proof[10]

A judge's assessment of evidence, such as whether a judge can rely on a document for the truth of its contents, is reviewed on a standard of palpable and overriding error that the finding of fact played an essential part in the reasoning.[11]

Reviewing inferences drawn from facts it is not sufficient that a different inference can be drawn from the facts.[12]

    R v Skinner, 2016 NSCA 54 (CanLII), NSJ No 255, per Saunders JA, at para 23("...a judge’s decisions on questions of fact are not evaluated on a standard of correctness. A high degree of deference is accorded. Even though opinions may differ with regards to particular factual rulings, they will not likely be disturbed because the margin or tolerance for deviation is wide enough to accommodate other outcomes which are reasonable and find support in the evidence. Recalling my analogy, striking the outer rings on the target will suffice and appellate intervention will not be warranted.")

Reviewing Findings of Credibility

See also: Analyzing Testimony

Matters of credibility are given considerable deference. [1] The trial judge has a "significant advantage" of being able to see and hear the evidence.[2] It is assessed not just of “what was said, but how it was said.”[3]

Unless there is a "palpable and overriding error" in the findings of fact by the judge in assessing credibility, the findings should not be overturned.[4]

Sufficiency of reasons in determining credibility are also accorded deference.[5]

  1. ↑ R v Gagnon, 2006 SCC 17 (CanLII), [2006] 1 SCR 621, per Bastarache and Abella JJ, at para 20 (... “It is very difficult for a trial judge to articulate with precision the complex intermingling of impressions that emerge after watching and listening to witnesses and attempting to reconcile the various versions of events. That is why this court decided..., that in the absence of a palpable and overriding error by the trial judge, his or her perceptions should be respected.”)

Question of Mixed Fact and Law

A question that is of mixed fact and law will be considered on a standard of "palpable and overriding error."[1]

Where the judge has considered all evidence required by law and comes to the wrong conclusion. This will be an error of mixed fact and law.[2]

However, where the issue may appear to be of mixed fact and law but relates to a failure to consider one or more factual findings, such error will normally be treated as a question of fact and not a mixed question.[3]

Where the question involves "the application of a legal standard to a set of facts", then it is a mixed question of fact and law.[4]

The following have also been considered questions of "mixed fact and law":
