Can the lawyer recommended by the police handling the case be used?

It is illegal. The public security organs are obliged to inform the parties that they have the right to hire a lawyer, and to explain to people with financial difficulties that they can apply for legal aid, but they cannot directly introduce lawyers. There are clear regulations on the management of prosecutors and judges, which the public security organs, as judicial organs, should abide by in criminal proceedings.

Legal basis:

People's Police Law of the People's Republic of China

Article 20 The people's police must enforce the law impartially and act impartially.

Article 46 Citizens or organizations have the right to report and accuse the people's police of illegal and disciplinary acts by the people's police agencies, people's procuratorates and administrative supervision agencies. The agency that accepts the report or accusation shall promptly investigate and handle the case and inform the reporter or accuser of the investigation results.
