Weight of authority

Definition

Weight of authority refers to the persuasive power or influence that a particular legal source or precedent holds within the legal system. It is essential in legal citation, as it helps to determine how much credence a court or practitioner should give to a source, like case law, statutes, or secondary materials, when making legal arguments or decisions.

1. The weight of authority can vary based on the jurisdiction and the hierarchy of the court system, with higher court decisions carrying more weight than those from lower courts.
2. When citing cases, practitioners must consider not only the relevance of the case but also its precedential weight and how it has been treated in subsequent rulings.
3. Secondary sources like law review articles can provide persuasive authority but typically carry less weight than primary sources like statutes and case law.
4. The weight of authority is crucial in establishing arguments during litigation, as stronger authorities can significantly influence judicial outcomes.

Review Questions

• How does the concept of weight of authority affect legal practitioners when preparing their cases?
  • Legal practitioners must carefully assess the weight of authority of their sources when preparing cases because it directly influences their arguments' strength. High-weight sources, such as binding precedents from higher courts, are essential for building compelling cases. Practitioners must also evaluate conflicting authorities to present the most persuasive arguments possible, which involves understanding how various sources have been treated over time.
• Discuss the role of binding and persuasive authority in determining the weight of authority in legal arguments.
  • Binding authority consists of legal sources that courts are obligated to follow, such as statutes and rulings from higher courts within the same jurisdiction. These sources carry significant weight of authority because they establish mandatory rules. In contrast, persuasive authority includes sources like lower court decisions or scholarly articles that may influence but are not required to be followed. Understanding the distinction between these types helps lawyers frame their arguments effectively by relying on the strongest available authorities.
• Evaluate how changes in case law can impact the weight of authority over time and its implications for future legal interpretations.
  • Changes in case law can significantly alter the weight of authority as new precedents may overturn or modify existing ones. When higher courts issue new rulings, they can reshape the legal landscape by either reinforcing prior decisions or establishing new interpretations. This evolution has profound implications for future legal interpretations, as attorneys must stay updated on shifts in authority to craft informed arguments that align with current judicial trends. The dynamic nature of case law necessitates ongoing analysis to ensure that practitioners are referencing authorities with appropriate weight.
