A bare denial of liability, without any substantive explanation or raising of triable issues, does not constitute a bona fide defence to resist summary judgment. When a defendant is confronted with documentary evidence (such as delivery notes and invoices bearing signatures of receipt) and can only respond with a blanket denial and insistence that the plaintiff must prove its case at trial, without pointing to any specific factual or legal issues in dispute, summary judgment will be granted. The summary judgment procedure is designed to prevent mala fide defendants from abusing court processes by delaying the inevitable where they have no arguable defence.
