What if I will not go back to India, my family members will be arrested. ??What are the other consequence all we have to face??
You will be declared as proclaimed offender. Your family members will not be arrested, in fact at one stage their case shall be split from yours and they may get get their cases disposed while your case shall remain pending.
Can I complain to higher authorities and media once I come back to India on that SHO and my wife’s relative since without any investigation (even if I showed them enough evidences about the fake allegations )they booked a FIR on me and my family members?? When should I do this??
You cannot do that, you simply have to contest and challenge all her false allegations during trial proceedings of the case.
Whatever allegation she mentioned all happened in other country, I have all the original stamped medical reports and police reports of my evidence from that country, should I need to attest those reports by respective embassies to present in the trail courts??(both India and the country where I am living embassies )
This is matter of trial, you can take up this during trial in the court.
Can I go for the quashing of my case in higher courts since the trial is not yet started with all proofs whatever I have??
You can go for quash once charge sheet is filed because quashing of FIR is generally not entertained by high courts.
Can I use DP act sec 3, 384 of IPC (I have audio recordings of my sister in-law demanding money) on my in-laws also since they mentioned Cleary in FIR about dowry??
Audio recordings are generally not admissible as evidence. You can contest the same in the trial court by drilling her during cross examination.
Last thing How about if I appoint someone with POA to attend the hearings behalf of me for all the proceedings??
There is no provision in law for POA representation in criminal cases for accused.
