What statement best describes mandatory authority?

Mandatory authority refers to legal principles or rules that must be followed by courts within a particular jurisdiction. This type of authority typically includes statutes, regulations, and case law from higher courts in the hierarchy that govern lower courts or tribunals. The crucial aspect of mandatory authority is that it creates an obligation for lower courts to adhere to the legal precedents established by higher courts, ensuring consistency and predictability in the law.

The essence of mandatory authority is its binding nature, which applies to all courts within the same jurisdiction. For example, if a state supreme court issues a ruling, all lower courts within that state must follow the precedent set by that ruling. This binding effect is essential in maintaining a uniform application of law across different cases with similar facts.

In contrast, the other options do not accurately capture the essence of what mandatory authority entails. While persuasive authority can influence a court's decision, it does not have the binding nature that mandatory authority does. Practitioners typically rely on mandatory authority because it carries legal weight and is necessary for effective legal argumentation. Additionally, mandatory authority is recognized by state law, as it arises from the structure of the judicial system and is enforced to ensure that legal decisions are made based on established law.
