You can still sue after mediation by the police station. If the mediation fails to reach an agreement or fails to perform after reaching an agreement, the parties may bring a civil lawsuit to the people's court according to law. Mediation means that under the auspices of the people's court, the people's mediation committee and relevant organizations, two or more parties negotiate voluntarily on the substantive rights and obligations of disputes, and through education and guidance, the parties reach an agreement to resolve disputes.

How to deal with the failure of mediation in police station

1. If mediation by the police station fails, the parties may bring a civil lawsuit to the people's court according to law.

2. The public security organ may mediate and deal with acts that violate the administration of public security, such as fighting and damaging other people's property caused by civil disputes, if the circumstances are relatively minor. If the parties reach an agreement through mediation by the public security organ, they will not be punished. If the mediation fails to reach an agreement or fails to perform after reaching an agreement, the public security organ shall punish the violator of public security administration in accordance with the provisions, and inform the parties that they can bring a civil lawsuit to the people's court according to law.
