How much longer will it take to resolve an injunction case in lok adalat

Myself and my father bought a land about year and half ago with our hard earned money to move our mechanic shop out of rental place. We checked for villangam and NOC before buying it was all clear. Area: 300sqft. Place: Chennai, Tamilnadu While we bought the land there was an existing hut in a demolished state. We cleared up the place to construct a new building. After we cleared the place and while we were about to start construction, the neighbor went to police station and complained that we were encroaching their land. The police did not file an FIR, but asked us to take it to court and file for injunction. We consulted a couple of lawyers and they said this case would be resolved within a week. But it’s been more than a year and half and still going on. After we filed a case in high court, the opposition part filed for vakkalat that no decision be taken without their concent and kept dragging the case by not showing up for concecutive 3 hearing but would show up for 4th hearing only to ask for more time. ( I got a feeling they were trying to dodge ex-parte). 6 months passed by with high courts and the judge ordered that case be resolved at lok adalat. Then we moved to lok adalat and the case has been going on for 8 months and opposition party is still following same trick of not showing up for 3 hearing and would show up for the 4th. The lok adalat judge fined the person for not showing up but he wouldn’t stop. The court said it would do “for-orders” in next hearing. He then filed a petition that he is very busy and not able to show up and asked the court to restart the case. So far he has submitted a petition that states that we are trying to encroach govt. property calling it poramboke land. it has collectors patta issued to a person from whom we got it from. Note: the opposition party has not submitted any document stating that it’s his land. Whereas the initial police station complaint was we were trying to encroach his land. The inspector did not file a FIR. The opposition party is simply trying to drag the case and wants us quit. Any suggestions would be helpful.
