Having failed to receive a majority of the court's votes, concurring opinions are not binding precedent (common law) and cannot be cited as such. But concurring opinions can sometimes be cited as a form of persuasive precedent (assuming there is no binding precedent already in effect). The conflict in views between a majority opinion and a concurring opinion can assist a lawyer in understanding the points of law in the majority opinion. Occasionally, a judge will use a concurring opinion to signal that he or she is open to certain types of "test cases" that would allow the development of a new legal rule. In turn, such a concurring opinion may become more famous than the majority opinion in the same case. A well-known example of this phenomenon is "Escola v. Coca-Cola Bottling Co." (1944).
