Suit for declaration

Sir, A property purchased in 1969 by paying it's challan (required fee of that time) in which name of my father and grandfather is mentioned, we have the original bank stamped slip (of 1969). In December 1995, my father wrote an application AC and requested for the entry of record and issue the True copy (Form-II) of situated 3 shops over area of 809ft. In March 1996, letter from record custodian (Mukhtiarkar) received and asked to appear infront of AC to receive the true copy of the record. My father appeared and got the True copy (Form-II) of the said area stating the allocation of the property with name of my father and grandfather in equal. (Copy of the application written by my father, original notice from revenue record custodian (Mukhtiarkar) and original entry in the form of Form-II (true copy) is also at us.) Last year, when destruction of the shops started for the purpose of reconstruction of shops, a relative asked to stop the work as one shop belonged to his father, as his father died (1965) so he is the owner of that shop now and he has the proof for that claimed shop. My father asked to bring the proof, he showed the proof (the paper called "Qabooliyat" at that time) to the local village jury in which the name of his father was written with pencil while , it was told by the people to him that this record is not acceptable. He refused their decision and approached the revenue office for preparation and entry of the record while we were unknown altogether. He got signed from AC over sale sale letter which was initially he managed to get in 2009 (but didn't mentioned till the destruction of shops last year), then he did registry of sale to his sons but when he went for the entry to (same) AC, he (AC) asked to show the original documents (RSD - Register Sale Deed). After checking RSD (Register Sale Deed documents) by AC, he put a note over the form (From-II) that "Seen Original RSD is not satisfactory so previous entry is cancelled". It was November 2015 when AC put a note his documents (which we didn't know at all), after waiting for about 6 six months from that relative to prove his claim but he din't then in February 2016 we submitted the copies of our record to AC and requested to check. When the relative person knew it, he submitted the SUIT through his sons in Civil Court against my father, himslef, AC, DC, Muhktiarkar, Board of Revenue etc. Civil Court dismissed the case in September 2016 upon the request from our side that case is not under Civil Court Jurisdiction (U/O VII Rule 11 CPC) because the plaintiff didn't went to the revenue forum and directly approached the Civil Court against the action of AC. Civil Court asked the plaintiff to go revenue form as AC cancelled the entries for which he has the right to cancel while their Registration is not cancelled by him. Plaintiff has submitted the SUIT appeal to Session Court rather going Revenue. Could you suggest please the strength of our case on the basis of our documents mentioned above as at present shops are closed while there are the locks to the shops by us but opponent has put his locks as well and taking rent from the people who sit infront of the shops upon basis of his influence. Regards,
