What are you talking about? 90% of litigation is convincing the judge that existing case law that clearly applies to your case does apply to your case.
EDIT: specifically around the use of judicial precedent in case-law.
90% of legal work where there is a plaintiff and defendant is pressuring a settlement. My wife, an attorney, does not consider that to be "litigation".
But, for your sake, it's probably best that you accept your wife's definition.
