Explanation / Scope

This principle establishes that a triable issue arises where the defendant’s affidavit raises issues requiring the plaintiff to explain matters or casts doubt on the claim. Where a bona fide issue arises, the case should be transferred to the general cause list. The principle applies where a defendant raises a defence. It ensures that cases with triable issues are properly heard. The principle reflects the need for full hearing on disputed facts. It prevents summary judgment where there is a genuine issue. The court must determine if a triable issue exists. The principle provides guidance on when a case is unsuitable for the undefended list.
