Lawyer
A lawyer is a person learned in the law and a person licensed to practice law. Law is the system of rules of conduct established by the sovereign government of a society to correct wrongs, maintain stability, and deliver justice. Working as a lawyer involves the practical application of abstract legal theories and knowledge to solve specific individualized problems, or to advance the interests of those who retain lawyers to perform legal services. The role of the lawyer varies significantly across legal jurisdictions. Often, lawyers brief a court in writing on the issues in a case before the issues can be orally argued. They may have to perform extensive research into relevant facts and law while drafting legal papers and preparing for oral argument. Lawyers are always free to form voluntary associations of their own, apart from any licensing or mandatory membership that may be required by the laws of their jurisdiction. Like their mandatory counterparts, such organizations may exist at all geographic levels.
The Judge
A judge, or arbiter of justice, is a lead who presides over a court of law, either alone or as part of a panel of judges. The powers, functions, method of appointment, discipline, and training of judges vary widely across different jurisdictions. The judge is like an umpire in a game and conducts the trial impartially and in an open court. The judge hears all the witnesses and any other evidence presented by the parties of the case, assesses the credibility of the parties, and then issues a ruling on the matter at hand based on his or her interpretation of the law and his or her own personal judgment.
A court is a form of tribunal, often a governmental institution, with the authority to adjudicate legal disputes between parties and carry out the administration of justice in civil, criminal, and administrative matters in accordance with the rule of law. In both common law and civil law legal systems, courts are the central means for dispute resolution. Some believe all persons have an ability to bring their claims before a court. Similarly, the rights of those accused of a crime include the right to present a defense before a court.
The systems of courts that interpret and apply the law are collectively the judiciary. The place where a court sits is a venue. Court proceedings occur in a courtroom. The building as a courthouse; court facilities range from simple and very small facilities in rural communities to huge buildings in large cities.
