Fake case against my family by an advocate

On 5th Oct 2016 my brother was going on a bike to drop two kids to school suddenly a Swift car collided with his bike and an argument was started and car driver and two others came out from car and abused him when he opposed the said conflict; then all three started to beat him very badly with an iron rod and fled away after injuring him seriously. he received serious injuries in head,eye,hands,ankle,fingers and his right leg was broken in many parts. Then we took him to govt. hospital and filed a F.I.R against accused under I.P.C. 279,323,325 and 506.and nothing happened in a year's time but now the accused has counter file a fake case (Plea #3815/17, section 323,504,506 & 427 IPC at ACJM-II court, room no.32, Ghaziabad) on my big brother and the victim and two others of my relatives, since accused is himself an advocate so please guide us what to do?
