Dear Client,

the Police may have the power to seize a passport under the Criminal Procedure Code, it does not have the power to retain or impound it. the Police seizes a passport, they must send it along with a letter to the Passport Authority. even a Court cannot impound a passport despite the enabling provision in Section 104 of the Code. the Passport Authority of India will not impound an NRI's passport on a mere complaint under section 498A. you can file a petition requesting the court to grant your passport to you stating the valid reasons. 498 A is for a non bailable offence and you need to give a solid evidence that the allegations are wrong. you would have applied for anticipatory bail and pre arrest notice from court before the arrest.

- if the accused is supporting the investigation / settlement /counseling, then there will be no restriction to travel the country resided by him.

- There is no limitation for a police official to call accused for investigation purposes before filing charge sheet , till his satisfaction. But if the accused is feeling harassment, he may approach the top official against him and also can file an application before the court against him for the said harassment or limitations.

-Under section 498A, if accused supporting the police official, then bail is not mandatory, means it becomes bailable as per latest Supreme Court judgment. 

1. Since, the FIR against your parents already quashed , then it seems that you have sufficient grounds for quashing the FIR against you as well. , specially when you are a foreign citizen now. 

- Further , even before filing the charge sheet , you can approach the High court , and it may take at lease 3 months to file the charge sheet. 

2. If your passport has impounded by the court , then you should approach the impounding court firstly , and if reject then approach the High Court 

- Since, you are an Australians citizen , then Court cannot hold your passport legally for such matrimonial cases , which not come under the heinous crimes. 

3. Never , 

4. Approach the session or High Court immediately after moving an urgent application with the application.  

1) If your spouse take case back then it will be quashed. Try to get middleman involved in this who was/were present at the time of marriage.

2) You can file request in high court by giving job reason.

3) Kindly get involved in this case Ministry of External Affairs to go back Australia before 23rd June.

4. You may have to file an application before trial court about this along with the copy of the visa and proceed accordingly. 

Quashing is to be done only in exceptional circumstances 

2) HC is reluctant to quash fir pending completion of investigations 

3) file application in trial court for return of passport and permission to travel abroad 

You had lawyer who quashed your parents and still you got arrested due to LOC.

Police can not keep your passport however you need court order to fly back.

Since you were not in India thatswhy chargesheet was not filed. 

You can give reason to fly because your visa is expiring so your further stay will be illegal.

Since you cn afford thatwhy directly approach HC but check your state timeline. 

Lower court will be faster in taking decision.

HC will be more liberal in decision. 

Permission to travel and other all things before trial court
