Identifying a road included only in the Panchayat Records

My neighbor along with another three persons residing adjacent to his property trespassed & constructed a new road through my (vacant property in Kerala). After filing an FIR with the police, I filed a civil case in the relevant Munsiff Court for a permanent Injunction against trespass, which is about to reach the trial stage. In their response, the defendants are claiming that the road in question is one of three Panchayat Road, as included in the records of the Panchayat office and submitted a document from Panchayat office which shows a list of three roads with details like staring point, ending point, length & width filled in the format, but other details like year of construction, protection wall length, Panchayat Number, Aq. Date & Book value, Addition date & Costas, Deduction date & & Cost etc asblank. There is no record to show how they acquired this document except that the document is signed and stamped by the Panchayat office and is submitted with a declaration from their advocate stating that this document is obtained officially from Panchayat. We know a road with the specified name is in the records of Panchayat. But this is a different one passing some properties away from our property. Our RTI queries to the Panchayat Officer, asking for the survey numbers of the properties having common boundaries with the road were returned with the reply that this information can be obtained only from Village office. However, as the road with the specified name (as in Panchayat records) is constructed after the resurvey, we could not get any relief from the Village Office also. The reply from Panchayat Officer to our RTI query also states that while the road with the specified name is included in the Panchayat Records, they do not have any record to show when or how this road was entered in the Panchayat records, or who contributed the land for constructing the road. As I am staying far away from the property, I can’t get any witness from the locality to testify on my behalf What option I can avail, or what document I can obtain through RTI to prove that the road with the name as in the Pnchayat Records is different from the one constructed through my property?
