Hi
1) You should obtain the No Objection certificate from SDJM court .
2) Since the High court has granted you the stay, the SDJM court should by default issue you the No Objection certificate.
3) You are required to request permission of the SDJM court and also provide an undertaking in a Rs10-/- stamp paper to the court as provided in http://passportindia.gov.in/AppOnlineProject/pdf/GSR_570_dtd_25.08.93.pdf
4) In general the courts will grant permission for issue of passport for a period of 1 year. However you need to impress upon the judge and request for issue of passport for a period of atleast 3 years as the cases get dragged for about 3 years.
5) Since it is an application to court, you need to address the petition to court only. You do not need to contact the Complainants for this petition or as a matter of fact, the complainant cannot even object to your petition
6) The request petition is a simple format addressed by you to the court stating your address, case details and the reason for overseas travel.
7) The request petition will be heard any time by the SDJM and need not wait for the regular hearing.
Hope this information is useful.
