Japan has a civil law legal system. Countries with civil law systems have extensive, frequently updated codes that make up their primary law. Important sources of Panamanian law include the Constitution, laws, legislative degrees, and regulations. Court decisions do not form binding precedent.
Most laws and cases from Japan will be in Japanese. English translations of documents are sometimes available, but translations are provided solely for convenience. The official Japanese versions have legal effect rather than any translated versions in other languages.
Subject law collections provide access cases and legislation from Japan and other countries pertaining to a specific subject area. Using a subject law collection is particularly helpful when you are comparing the laws of more than one country.
