What is the test for an opening brief in a personal injury action?

Further, an opening brief must contain a "summary of significant facts." (Cal. Rules of Court, rule 8.204(a)(2)(C).) Defendant's briefs include an enormous amount of testimony, not all of which is significant, often without any argument as to its relevance. In the opening brief defendant's occasional conclusory arguments are tucked into the facts, often making it difficult to grasp the substance of his claims. These rules violations could result in a forfeiture of defendant's claims. (Cal. Rules of Court, rule 8.204(a)(1)(B); Benach v. County of Los Angeles (2007) 149 Cal.App.4th 836, 852.)
