When a decision in an appellate case establishes new law, changes existing law, or is of the utmost importance, the appellate court will publish the Opinion. These published opinions are citeable and carry precedence in determining future cases. The majority of decisions by appellate courts are unpublished. Thus, these published opinions are reserved for cases that establish binding law. The following are some of Farrell & Associates’ noteworthy, published opinions:
