The body of law developed from court judgments rather than laws is known as common law or case law.
The common law is used when written laws or statutes cannot be used to decide a decision’s conclusion. When a common-law court hears a new case, it turns to previous precedents for guidance.

The courts of English monarchs are the source of common law in American courts. Many of the colonies of the British Empire are still governed by the common law system that the British Empire introduced.
Differences Between the Common Law and Other Legal Systems
In contrast to common law, civil law is a body of legally codified statutes and laws enacted by legislators as opposed to the common law. Judges in civil law use the civil code to analyze cases and provide judgments.
Cases may be taken to court in civil systems, and there are specific rules governing how claims are handled and the penalties for offenses. Civil and common law’s purpose is to achieve consistent results by following the same interpretive criteria.
As a result, certain nations have customary laws based on established patterns of behavior or conventions. Countries in other parts of the world have legal systems based on religious scriptures or traditions.
Islamic nations have a high prevalence of religiously based legal systems. Mixed legal systems are popular in various nations, combining common law and different legal systems.
