Cases

McDonalds Corp v Steel and Morris

Held

A plea of justification was not required to be supported by 'clear and sufficient evidence' before being placed on the record, and should not be struck out unless it could be clearly demonstrated to be incurably bad. Before pleading justification a defendant should (i) believe that the words complained of were true; (ii) intend to support the defence at trial; and (iii) have reasonable evidence to support the plea or reasonable grounds to suppose that sufficient evidence to prove the allegations would be available at trial.
