Excuse me: The case is still in the investigation stage. What are the procedures for lawyers to meet with criminal suspect Xu? The case entered the stage of examination and prosecution, and the lawyer met with the suspect. In the investigation stage, when a lawyer meets a criminal suspect, the relatives of the criminal suspect shall handle the entrustment formalities, and the lawyer shall apply to the case-handling organ for an interview with the power of attorney and the lawyer's letter of introduction. In the stage of examination and prosecution, lawyers should also have entrustment procedures when meeting with criminal suspects, and the prosecution opinions of public security organs and the meeting letters of law firms should meet with criminal suspects. Of course, you must carry a lawyer's license.
