In a civil law system, which is based on Roman law, the key justice participants include:1. Judges: Judges play a crucial role in the civil law system. They are responsible for interpreting and applying the law to resolve disputes between parties. Judges are typically highly trained legal professionals who have the authority to make binding decisions.2. Lawyers: Lawyers, also known as attorneys or advocates, represent the parties involved in civil cases. They provide legal advice, prepare legal documents, and present arguments on behalf of their clients in court. Lawyers may specialize in different areas of law, such as family law, contract law, or tort law.3. Plaintiffs and Defendants: In a civil case, the plaintiff is the party who initiates the legal action by filing a complaint or petition. The defendant is the party against whom the complaint is filed. The plaintiff seeks a legal remedy or compensation from the defendant, who may dispute the allegations or present their own counterclaims.4. Witnesses: Witnesses play a crucial role in presenting evidence in a civil case. They provide testimony under oath to support or refute the claims made by the parties involved. Witnesses can be called by either party or summoned by the court to testify about relevant facts or events.5. Experts: In some civil cases, experts may be called upon to provide specialized knowledge or opinion on specific matters. These experts, such as forensic scientists, medical professionals, or financial analysts, offer their professional expertise to assist the court in understanding complex issues related to the case.6. Court clerks: Court clerks are responsible for administrative tasks within the court system. They assist judges with managing court dockets, maintaining case files, scheduling hearings, and ensuring the proper documentation of court proceedings.7. Mediators and Arbitrators: In civil law systems, alternative dispute resolution methods like mediation and arbitration are often used to resolve disputes outside of the courtroom. Mediators facilitate negotiations between parties to reach a mutually acceptable resolution, while arbitrators act as neutral decision-makers who render a binding judgment.It’s important to note that the specific roles and terminology may vary across different civil law jurisdictions, but these participants generally play fundamental roles in the civil justice system.
