Encroachment Query

My father purchased a small plot measuring 225 sq mts in Goa in 1984. However he didn’t fence the plot. In 2014 the neighbour reconstructed his plot. As per reconstruction rules he needs to leave 3 mts around his plot. However he has left only . 78 mts between his and my plot. In addition to this he has built a septic tank on the northern side of my property measuring 3.5 sq mts. Encroach meant also involves a tarred road of 12.5 sq mts and a kaccha road of 18.3 sq mts. I have filed legal proceedings against him for the above mentioned encroachments. I have produced the survey plan of my property. Through RTI I also found out from the panchayat that he hasn’t taken any permissions while reconstructing. How does my case look and what additional steps should I take to make it strong. Considering the size of the plot I cannot afford to part with the land. Also will I be able to levy a fine on him for using my land illegally for his waste management since March 2014?
