Due to some of your negligence in handling this matter, which has created an unfavorable situation for you, you can now ask the police to retrieve police records to prove the actual dispute between the two parties. If you have already suffered damage, then go to the hospital to issue a medical record and proof of the other party's condition due to the beating. In this way, you may be able to gain some initiative in the lawsuit. Of course, you can fight for some initiative.
