In determining whether to grant a Rule 18A trial on part of a trust application, what is the risk that the findings of the application may be carried over to the subsequent determination of other issues?

In reaching my conclusion that I should decide the application insofar as the trust claims are concerned, I am mindful that there may be times when deciding some but not all of the claims made in a case can lead to unforeseen adverse consequences if findings are carried over to the subsequent determination of other issues. That risk is minimized because I am the case management and trial judge of this and the related actions. ... I draw comfort from the remarks of Donald J.A. in Graham v. Moore Estate, 2003 BCCA 497, where he said at para. 35: Sometimes splitting the issues in a case can lead to the unavoidable result that findings carry over to the later determination of unresolved issues. That is a consideration to be factored into the decision whether to grant a Rule 18A trial on part of the case, but it is not necessarily a determinative factor. Where, as here, the case is under the management of a single judge who hears all aspects of the case, the danger of injustice is minimized.
