The writing is thick with legal jargon and I am not a lawyer. It has to do with legal details, evidence and the likelihood that the plaintiff will succeed with the presented evidence. For example, if car A is stopped at a stop light and car B fails to make a legal stop as required and hits car A thus damaging it; then, especially if there are witnesses, the case would be won because of its success on the merits of the evidence. As far as the technical legal jargon, that's best left with the lawyers.
