Dowry harassment and domestic violence

Sir, We belongs from Punjab and my sister got married in Haryana 10 years ago and we gave everything possible the groom side demanded (jewellery and house furniture etc), she has 2 kids, her husband do not work regularly, he has been torturing my sister physically on question of dowry from last few years. She never shared this to us when we came to know all this we asked from her in detail and filed a complaint to SSP Punjab from where the case has been sent to Women cell and my sister agreed to live with her and we compromised. After passing 1 year he again started doing same thing and now my sister came our home and they himself dropped my sister to us with her kids , as she came here the other party filed a complaint against my sister that she is threatening them. Now As they breached the earlier compromise, we are going to file a complaint again to SSP Mohali on same. (We want to settle the case and want they live together but they again and again doing the same thing) My question is that the complaint they filed relates to haryana. How their that complaint harm us and shall we put our case to ADR to settle the issue and get legal binding which cannot be breached.
