Elucidate Doctrine of Res Judicata in the Light of Decided Cases

Authors Avatar

1. Introduction

RES JUDICATA means "a thing decided" in Latin. It is a common law doctrine meant to bar re-litigation of cases between the same parties in Court. Once a final judgment has been handed down in a lawsuit subsequent judges who are confronted with a suit that is identical to or substantially the same as the earlier one will apply res judicata to preserve the effect of the first judgment. This is to prevent injustice to the parties of a case supposedly finished, but perhaps mostly to avoid unnecessary waste of resources in the court system. Res judicata does not merely prevent future judgments from contradicting earlier ones, but also prevents them from multiplying judgments, so a prevailing plaintiff could not recover damages from the defendant twice for the same injury.

1.1 Research Methodology:

The researcher has used doctrinal method and relied only upon secondary sources of data to prepare this project.

1.2 Hypothesis:

Res judicata does not restrict the appeals process, which is considered a linear extension of the same lawsuit as it travels up (and back down) the appellate court ladder. Appeals are considered the appropriate manner by which to challenge a judgment rather than trying to start a new trial, and once the appeals process is exhausted or waived, res judicata will apply even to a judgment that is contrary to law.

2. Meaning of Res Judicata

RES JUDICATA means "a thing decided" in Latin. It is a common law doctrine meant to bar re-litigation of cases between the same parties in Court. Once a final judgment has been handed down in a lawsuit subsequent judges who are confronted with a suit that is identical to or substantially the same as the earlier one will apply res judicata to preserve the effect of the first judgment. This is to prevent injustice to the parties of a case supposedly finished, but perhaps mostly to avoid unnecessary waste of resources in the court system. Res judicata does not merely prevent future judgments from contradicting earlier ones, but also prevents them from multiplying judgments, so a prevailing plaintiff could not recover damages from the defendant twice for the same injury.

Res judicata includes two related concepts: claim preclusion, and issue preclusion (also called collateral estoppel), though sometimes res judicata is used more narrowly to mean only claim preclusion. Claim preclusion focuses on barring a suit from being brought again on a legal cause of action that has already been finally decided between the parties. Issue preclusion bars the re-litigation of factual issues that have already been necessarily determined by a judge or jury as part of an earlier claim. It is often difficult to determine which, if either, of these apply to later lawsuits that are seemingly related, because 
many causes of action can apply to the same factual situation and vice versa. The scope of an earlier judgment is probably the most difficult question that judges must resolve in applying res judicata. Sometimes merely part of a subsequent lawsuit will be affected, such as a single claim being struck from a complaint, or a single factual issue being removed from reconsideration in the new trial.

Res judicata does not restrict the appeals process, which is considered a linear extension of the same lawsuit as it travels up (and back down) the appellate court ladder. Appeals are considered the appropriate manner by which to challenge a judgment rather than trying to start a new trial, and once the appeals process is exhausted or waived, res judicata will apply even to a judgment that is contrary to law.

However, there are limited exceptions to res judicata that allow a party to attack the validity of the original judgment, even outside of appeals. These exceptions--usually called collateral attacks--are typically based on procedural or jurisdictional issues, based not on the wisdom of the earlier court's decision but its authority or competence to issue it. A collateral attack is more likely to be available (and to succeed) in judicial systems with multiple jurisdictions, such as under federal governments, or when a domestic court is asked to enforce or recognize the judgment of a foreign court.
