What does the phrase "on all fours" refer to in legal terms?

The phrase "on all fours" in legal terminology refers to cases that share similar underlying facts and circumstances. When a situation is described as being "on all fours," it indicates that the specifics of the current case closely resemble those of a precedent or previous case. This similarity makes it more likely that the court will apply the same legal principles and rules to the current matter that were used in the earlier case.

This concept is significant within the legal system as it helps establish consistency in judicial decisions and allows attorneys to argue that a particular case should be governed by existing precedents due to the factual similarities. Thus, when referencing cases that are "on all fours," it emphasizes the importance of factual congruence in legal reasoning and the application of established legal doctrine.
