[The judge] must consider whether [the plaintiff] has standing to bring an application under Rule 16-46 [of the Queen's Bench Rules], to require proof of the will in solemn form, or for an order revoking the grant of probate under Rule 16-47. . . . . . Rule 16-46 ... permits an application by any person who “... is or may be interested in the estate.” The grammatical and ordinary meaning of the word “may” in Rule 16-46 connotes possibility ... the use of the phrase “may be interested” means that a person does not have to establish a definite interest in the estate to establish standing. A possible interest, within the context of the applicable law and the specific factual circumstances, is enough to ground standing.

... what is referred to as “bootstrapping.” This is the situation where a party seeks to supplement what would otherwise be considered deficient evidence with allegedly “new” evidence and arguments on appeal.
