Judiciary
The Supreme Court of the United States stands as the highest court in the federal judiciary. This institution represents one pillar of a system designed to interpret, defend, and apply law for the state. The judiciary operates under the doctrine of separation of powers. It generally does not make statutory law or enforce law. Those tasks belong to the legislature and executive branches respectively. Instead judges focus on interpreting law applied to specific facts. In many jurisdictions courts possess power to change laws through judicial review. Courts with this authority may annul laws incompatible with higher norms like constitutions. Judges constitute a critical force while avoiding political bias. Some countries allow the judiciary to create common law alongside statutes.
Archaic Roman Law spanned from 650 BC until 264 BC. Ius Civile formed the most important part of early legal systems. Mos Maiorum represented rules based on social norms created by predecessors. Leges were rules set by leaders starting with kings then popular assemblies. Between 451 BC and 449 BC Mos Maiorum was written down in the Twelve Tables. Early legal processes involved two phases called In Iure and Apud Iudicem. Priests initially headed the judicial system since law was part of religion. Later the shift occurred from priest to praetor as head of the system. Praetors issued edicts declaring new laws or principles during their elected year. The Principate era began with Augustus reign around 27 BC. Hadrian collected all praetorian edicts into one document known as edictum perpetuum. A new process called cognitio extraordinaria emerged due to empire largess. This single-phase process presented cases directly to professional judges representing the emperor. Legal experts studied law and advised the emperor during this period. Dominate era lasted from 284 AD until 565 AD. Justinianus codified all Roman Law into Corpus Iuris Civilis. This collection included Institutiones, Digesta, Codex, and Novellae parts.
Education expanded beyond monasteries and abbeys to cathedrals and city schools in the 11th century. Universities eventually formed with five faculties including arts medicine theology canon law and civil law. Canon law represented laws created by the Pope heading the Roman Catholic Church. The rediscovery of Corpus Iuris Civilis happened in 1070. Roman law handled worldly affairs while canon law addressed church-related questions. Kenneth Pennington identified sources of medieval law as diverse including consilia and decretals. Early scholastics ran from 1070 until 1263 when Accursius wrote Glossa Ordinaria. Professors at Bologna University taught Roman law after rediscovering Digesta. Glossators translated old Roman laws creating literature around them. Summae provided summaries while Brocardica offered short mnemonic sentences. Quaestio Disputata used dialectic methods seeking arguments then refuting them. Late scholastics period extended from 1263 until 1453. Post-Glossators or Commentators wrote comments treatises and consilia logically. Gratian organized all church law into Decretum forming first part of Corpus Juris Canonici. This collection remained in use until Pentecost the 19th of May 1918. A revised Code of Canon Law obtained legal force on the 27th of May 1917 promulgated by Pope Benedict XV.
Courts interpret constitutions statutes and regulations within common law jurisdictions. They also make law limited to facts of particular cases where legislature has not acted. Tort of negligence often derives from case law rather than statute law in most common law areas. Common law decisions set precedent for all courts to follow. This principle is sometimes called stare decisis. The term common law refers specifically to this kind of judge-made law. Courts fill legislative gaps through prior case law interpretation. Judicial review allows annulment of laws incompatible with higher norms like treaties. Some countries allow judiciary to create common law alongside statutory frameworks. The process involves interpreting existing rules while applying them to specific factual scenarios. Precedent ensures consistency across different court levels and geographic regions. Legal experts study these precedents to advise governments and individuals.
Japan maintains a longer selection process for judges compared to United States or Mexico. Assistant judges complete training at Legal Training and Research Institute located in Wako. These assistants cannot sit alone until serving five years appointed by Supreme Court of Japan. Judges require ten years practical experience as public prosecutors or practicing attorneys. Japanese judicial branch contains Supreme Court eight high courts fifty district courts fifty family courts and 438 summary courts. Mexican Supreme Court justices serve fifteen-year terms after presidential appointment and Senate approval. Other Mexican justices serve six-year terms appointed directly by the Supreme Court.
