What is the case law in favour of striking defamation claims against two defendants?

First, they argue that the reputation of both the plaintiff and the defendants are engaged in a defamation suit. By striking the more egregious claims, the court will deny the defendants the chance to vindicate themselves. As authority for this position, they cite Robinson v. Furlong, 2015 BCSC 1690. There, Justice Wedge considered two parties who had made prima facie defamatory statements about each other. The central issue in that case was whether the defendant's alleged defamation was defensible as a response to attack. Both parties' reputations were engaged in that case because, as the court held, the plaintiff had attacked the defendant's character, conduct, and credibility in response to which the defendant made bona fide responses to defend his reputation.
