Non repayment of booking amount on cancellation

I booked a property in Enkaya garden taloja about 4yrs back by paying 1.85lac and canceled it within a year as there was no progress in the property development (the property is still as it is in undeveloped phase even today) After 8months the builder paid back 50000 and all his part payment cheque s either expired as he sent mails not to deposit them. I filed a case with maharera but the adjucating officer ruled in builder s favor saying the case isn't valid as we cancelled before maharera act came into existence,this after in the previous sitting the builder infront of the officer had admitted to pay the entire amount including the maharera fee in the subsequent sitting,also the builder was absent on the ruling day.we even have a rozanama of tehe sitting.its been almost year since and still no sign of payment from the builder. Going to consumer Court means a.couple more years of Court struggle. Is there a faster way out. The economic wing of Vashi police station didn't take our complaint.
