In a highly anticipated decision, the Supreme Court of Canada (the "SCC") in Barendregt v Grebliunas, 2022 SCC 22 confirmed the appropriate test for admitting additional evidence on appeal.

This decision confirms that the long-standing test set out in R.v. Palmer, [1980] 1 SCR 759, applies both to evidence that existed at the time of trial but was not adduced at that time, and to "new" evidence that came into existence following the trial.

In Palmer, it was established that four criteria ought to be used to determine if appellate courts should exercise their discretion to admit additional evidence on appeal:

1. the evidence could not, by the exercise of due diligence, have been obtained for the trial;
2. the evidence is relevant in that it bears upon a decisive or potentially decisive issue;
3. the evidence is credible in the sense that it is reasonable capable of belief; and
4. the evidence is such that, if believed, it could have affected the result at trial.

Barendregt deals with a family law dispute where the British Columbia Court of Appeal (the "BCCA") considered whether to admit evidence not adduced at trial. The BCCA characterized this evidence as "new" and therefore did not apply the test set out in Palmer.

The SCC overturned the BCCA's decision and confirmed that the test established in Palmer ought to have been applied.
