The document discusses the judiciary branch and legal systems. It covers: 1) The judiciary branch stems from the need to interpret basic laws and legal frameworks. It is often insulated from political processes to maintain impartiality. 2) Legal cultures shape attitudes toward law and the role of laws and institutions. They determine if a regime is limited by law or uses laws to control individuals. 3) Legal systems include common law, civil law, socialist law, and non-Western systems. Common law relies on judicial precedents while civil law uses comprehensive legal codes.
