<Tr> <Td> Venezuela </Td> <Td> Civil law </Td> </Tr> <P> Common law and equity (legal concept) are systems of law whose sources are the decisions in cases by judges . Alongside, every system will have a legislature that passes new laws and statutes . The relationships between statutes and judicial decisions can be complex . In some jurisdictions, such statutes may overrule judicial decisions or codify the topic covered by several contradictory or ambiguous decisions . In some jurisdictions, judicial decisions may decide whether the jurisdiction's constitution allowed a particular statute or statutory provision to be made or what meaning is contained within the statutory provisions . Statutes were allowed to be made by the government . Common law developed in England, influenced by Anglo - Saxon law and to a much lesser extent by the Norman conquest of England, which introduced legal concepts from Norman law, which, in turn, had its origins in Salic law . Common law was later inherited by the Commonwealth of Nations, and almost every former colony of the British Empire has adopted it (Malta being an exception). The doctrine of stare decisis, also known as case law or precedent by courts, is the major difference to codified civil law systems . </P> <P> Common law is currently in practice in Ireland, most of the United Kingdom (England and Wales and Northern Ireland), Australia, New Zealand, Bangladesh, India (excluding Goa), Pakistan, South Africa, Canada (excluding Quebec), Hong Kong, the United States (on a state level excluding Louisiana), and many other places . In addition to these countries, several others have adapted the common law system into a mixed system . For example, Nigeria operates largely on a common law system, but incorporates religious law . </P> <P> In the European Union, the Court of Justice takes an approach mixing civil law (based on the treaties) with an attachment to the importance of case law . One of the most fundamental documents to shape common law is the English Magna Carta, which placed limits on the power of the English Kings . It served as a kind of medieval bill of rights for the aristocracy and the judiciary who developed the law . </P>
