Understanding Precedent: How to Leverage Past Decisions in Current Cases

In the legal profession, precedent plays a central role in shaping the outcome of cases. Precedent, or stare decisis—a Latin term meaning “to stand by things decided”—refers to the principle that courts should follow previous decisions in similar cases. It ensures consistency, stability, and predictability in the law, which ultimately enhances fairness and guides lawyers in crafting their arguments and strategies. For attorneys navigating current cases, understanding how to leverage past decisions effectively is crucial. 

The Concept of Precedent in Law

Precedent serves key functions in the legal system: it ensures stability and predictability, allowing individuals and businesses to anticipate legal outcomes; fosters consistency and fairness by treating similar cases alike; improves judicial efficiency by applying established principles; and allows the law to evolve over time, adapting to societal changes and advancements.

In most cases, decisions made by higher courts, such as appellate courts and the Supreme Court, are considered binding on lower courts within the same jurisdiction. These decisions, particularly those of higher courts, provide the legal framework and reasoning that judges in future cases will refer to in resolving similar issues. This system promotes a sense of legal continuity and consistency.

There are two types of precedent: binding precedent and persuasive precedent:

1. Binding Precedent: When a higher court issues a ruling, that decision must be followed by lower courts in future cases with similar facts or legal issues. Binding precedent typically arises from appellate court rulings and is required to be followed within the same jurisdiction.
   
2. Persuasive Precedent: This refers to decisions from courts in different jurisdictions or from courts of equal rank that are not binding but can still be influential. Lawyers often look to persuasive precedent to support their arguments, particularly in novel or unique legal situations where binding precedent may not exist.

Understanding both forms of precedent and their applicability to the case at hand is vital for attorneys when determining how to structure their arguments and whether they can rely on previous decisions to bolster their case.

How to Leverage Precedent in Current Cases

For attorneys, leveraging precedent effectively is key to advocating for their clients. Below are several strategies that lawyers can use to incorporate precedent into their legal arguments:

Identifying Relevant Precedent

The first step in leveraging precedent is identifying relevant decisions that apply to the legal issues in the current case. This involves thorough legal research to find cases with similar facts, legal issues, and rulings. A good starting point is to review rulings from higher courts, such as the appellate courts or the state’s highest court, as these decisions are binding.

Assessing Binding vs. Persuasive Precedent

Once relevant cases are identified, attorneys must assess whether the precedents are binding or persuasive. Binding precedent requires courts to follow the previous decisions, while persuasive precedent, although influential, is not mandatory.

If the precedent is binding, attorneys must ensure they comply with it. If it’s persuasive, attorneys have the flexibility to use it to support their arguments but are not required to follow it strictly. In cases involving persuasive precedent, lawyers may present arguments about why the court should adopt the reasoning from another jurisdiction or why it should follow a different line of reasoning.

Distinguishing from Precedent

Not all precedents apply to every case, and an attorney may face situations where the facts or legal issues in the current case differ from those in the prior decisions. In these cases, attorneys can argue that the current case should be distinguished from the precedent.

To distinguish a case, an attorney will emphasize the differences in the facts, parties involved, or legal principles at issue. This can be an effective strategy when seeking a more favorable ruling or when trying to demonstrate that the prior ruling is outdated or not applicable to the present circumstances. By focusing on key distinctions, attorneys can make a case for why a different legal conclusion is warranted.

Overturning Precedent

In some cases, attorneys may seek to challenge or overturn existing precedent. While this is more challenging, it may be appropriate in cases where the law has evolved or societal views have changed significantly. When attempting to overturn precedent, attorneys must present compelling arguments showing that the previous decision was wrongly decided or that changing circumstances necessitate a new interpretation.

Judicial opinions often provide guidance on how to approach overturning precedent. For example, if a legal standard established by a previous case no longer aligns with contemporary values or legal reasoning, an attorney may argue that it’s time for the court to reconsider the decision.

Citing Recent Developments in Precedent

As the law evolves, new decisions may refine or reshape existing precedent. Lawyers must stay informed about the latest rulings and judicial trends to ensure that their arguments are based on the most up-to-date legal principles. Citing recent developments in precedent can strengthen an argument, as it shows the lawyer is aware of the court’s evolving stance on particular legal issues.

For example, if a recent Supreme Court decision shifts the legal landscape in a particular area, attorneys can cite this case to support their position in current litigation. Additionally, citing recent lower court cases that build upon or refine past decisions can help demonstrate that the law is developing in a way that favors their argument.
