From which system did the US Court system develop?

The U.S. Court system developed primarily from English Common Law, which serves as the foundation for legal practices in the United States. English Common Law is characterized by the system of case law, where legal precedents established by court decisions play a crucial role in shaping law. This body of law developed over centuries in England and was brought to America by English colonists.

Common Law emphasizes the role of court decisions and the concept of stare decisis, meaning that courts are bound to follow precedents set by previous decisions when resolving similar legal issues. This system promotes consistency and predictability in the law, which are vital components of the U.S. legal framework.

The other options, while influential in various legal traditions around the world, did not form the core basis of the U.S. judicial system. Roman Law, for example, is a foundation for many civil law systems, French Civil Law has shaped legal systems in several countries, and Spanish Law has influenced legal practices in Latin America, but they do not represent the structure and principles that underpin the common law tradition in the United States.
