The law firm is one of the few civil institutions that deals with all the trade violations of its members within this institution through law enforcement authorities (prosecutors and courts). The Criminal Prosecutor's Office is headed by the Criminal Prosecutor and this position is appointed by the members of the Board of Directors at the beginning of each 2-year period for the duration of the same period. The prosecutor can select a sufficient number of assistant prosecutors through the board of directors, and one or more of these prosecutors are selected and appointed as deputy prosecutors by the board of directors. Although prosecutors and assistant prosecutors are appointed through the board of directors, they have jurisdictional independence in conducting preliminary investigations and verifying violations and if they do not verify the complained or reported violation, they will issue a restraining order and the president of the bar association will issue a restraining order on behalf of the board of directors within 10 The day after notification, he will have the right to object to this decision, and this is for the judicial independence of the prosecutor and the assistant prosecutors from the board of directors. The role of the prosecutor's office is to verify the violation, and if the lawyer's violation is confirmed, a prosecution order is issued and the case is sent to the disciplinary court by issuing an indictment to issue a verdict. In addition to the Prosecutor's Office, there is another pillar called the Criminal Court, which is established in two or more branches according to the needs of each bar association, and in each branch, three judges are appointed as members of the court, and the most senior member of the court presides over it. In addition to dealing with the indictment issued against the lawyers, the disciplinary courts sometimes issue judgments directly in the cases without commenting and filing a case in the disciplinary court. For example, in the case of a request for the suspension of a lawyer, which is submitted to the bar association by the members of the board of directors or other authorities, the disciplinary court directly enters into the proceedings and issues a decision to deal with the request for the revocation of the attorney's license in order to lose the conditions of attorney at the request of the board of directors, or The temporary suspension of a lawyer for the commission of a crime is brought up and dealt with directly in the disciplinary court at the discretion of the disciplinary court. The court can appeal the acquittal and disciplinary conviction, but the head of the bar association and the disciplinary prosecutor have the right to appeal against the acquittal or disciplinary punishment of degree 4 and higher, and finally, the lawyer also has the right to appeal against the sentences of punishment of degree 4 and higher. All objections are dealt with in the High Disciplinary Court of Judges based in Tehran and the decision of that court is final and enforceable for the execution of the judgments, which under the supervision of the Disciplinary Prosecutor in the Prosecutor's Office executes all the final judgments according to the regulations.
