I understand that you are suffering from pain and I completely agree with you that your daughter has been killed. I also understand that this may have killed your daughter.
Look Subho! you are just making an abuse of court procedure and just wasting the time of the concerned court. It is just because of you people, who delay the matters in the court just in order to harras the other party, the courts have long pending disputes in the court and the courts cannot get time to handle the serious dispute.
I want you to understand one thing that delaying the matter for one or two years will not give you justice nor it will calm you in any way. I also want you to understand that your this technic may set an example for other people to delay the court proceedings. If we lawyer will not stop you people from taking such steps, this process of delay in courts will continue and no one is ever going to get the justice from the courts because the justice delayed is justice denied.
Tomorrow! you may be implicated in any case, may be falsely. The other party in your case may also get the court cases delayed by using such methods and you may also get harrased. Will you like this at that time.
We have not stringent law in our Indian legal system to held the boy guilty in your case. We have loopholes in our legal system and he is getting advantage of this loophole. what you can do is get the strong evidence and strong arguments in your case, go to higher courts by appealing and get the boy held guilty. The lower courts work on question of facts and the higher courts work on question of law. You may get justice in higher courts but i am sure you are not going to get justice in the trial court where you are trying to linger on the proceedings. If you will delay the matters like this, you are not going to get justice in any way and you are just harrasing yourself.
