Judicial organs include courts, procuratorates, public security organs (including state security organs), judicial administrative organs and their leading lawyers' organizations, notary organs and reeducation-through-labor organs.
The work of the judicial department is to safeguard the law, ensure the correct implementation of the law, and resolve disputes; However, the specific definition of "justice" and the power of judicial departments are somewhat different in different legal systems.
In the civil law system, the court will conduct a specific investigation of the case; The judge will summon witnesses and cross-examine witnesses, defendants, etc. The court has the power of legal interpretation, but it does not necessarily have the final power of legal interpretation. As long as you feel that you are really "reasonable", you can use legal weapons to safeguard your legitimate rights and interests and promote social fairness and justice!
