Consumer forum case

I as a small developer had sold small plots in Raipur Chhattisgarh. With garden , gate , plantation by the road side n marking pole. A buyer had given me 2 lacs rupees for the booking. The plot costing was 130000/- per 1000/- sq. ft . So per sq. ft is 130/- rupees. When he had done the case I was not aware n within 2 month one sided order was announced to deliver the plot with all written facility in the brouchure . The facility v have already made . Our case got time barring in state forum also . In National commission v had filed n then withdrew case according to our lawyers instructions. Consumer forum had order to give 4000/- sq. ft plot n garden, gate , marking pole , n plantation on the side of the road . What v have done . V had taken the permission from gram panchayat. Now when the order is in his favour I told him to either take the plot or take 18% interest as compensation which he is not agreeing to . He is demanding to get permission from town and country planning n Sdm noc which is technically not possible as the land is out of town and country planning. For this permission he is blackmailing me for a sum of rupees 40 lacs where as he has paid only 2 lacs only . I am telling my lawyers to refund the amount with what ever interest the court says but the lawyers r saying order has been passed and its execution is on so that thing cannot change . Actually he doesn't wants land he wants 40 lacs amount out of court settlement. Want to know what can be the exit route for this trap . N is there any national forum order in past where the sum receiver has said to refund the amount with interest n court has passed that order . Jus for 2 lacs he is harassing us so much or can any blackmailing legal case can be done on him .
