Q1. 90 days of submitting the chargesheet time is already over, But I.O. still not submitted his final report. What to do now ?
The 90 days limit is when the accused is in custody. Be patient, it would come to you as a matter of right
Q2. After how many days summons sent to me by court ?
When the matter is listed in court, the court would send summons.
Q3. I need Lie Detector test to proove innocence against all allegations over myself, Is it possible if requested by myself on my very first date to magistrate ?
NO. That is wishful thinking. Accused can not use it in his own defence.
Q4. Main fact is still i loved her as she is first girl in my life till date may be this is only physical attraction or something else, Is it safe to take her home or not ?
Not if you don't want to commit suicide.
Q5. Also i dont want to keep any type of relation's with her family members / relatives, If she agreed to continue with myself ?
:-) Wishful thinking,
Q6. My complaint submitted against defaulter's is too with same I.O. and he don't take any action on our complaint, What to do ?
You need counselling of the procedures and come out of your delusions. The IO won't take any action
Q7. Also suggest, What to do on the trial dates, Is my presence must in court ?
Stay Mum. Let things upfold. Trust your lawyer to do thorough cross-examination etc.
Q8. My lawyer suggest me for cross case before trial starts with section 156 (3) / Anti Dowry/ Defamation, Is it right process to move further ? (We had several videography shown over media/ newspapers/ E-mails/ snaps to proove right picture, But i had short of time)
No comments w/o seeing all the evidences etc. But cross-case is just for money making of the lawyer mostly, Nothing much comes out of it.
BTW, I am also amazed that you spent 15 days in prison. There must be some reason for the same, In Delhi no one should spend so much time in Jail in Vanilla 498-a.
