What is the test for establishing that the evidence presented at trial was reasonable diligence?

New Brunswick, Canada

The following excerpt is from Adams v. Borrel, 2009 NBQB 186 (CanLII):

In Scott v. Cook the test is simply: (1) if presented at trial would the evidence change the result; and (2) could the evidence have been obtained with reasonable diligence before the trial?

In Ladd v. Marshall the test is: (1) it must be shown the evidence could not have been obtained by due diligence; (2) would the evidence have an important influence on the trial; and (3) the evidence must be credible, although not incontrovertible.
