Dear Shruti,
There have been certain instances where in if the girl is educated and still her family agrees to get her married despite having demand for dowry, cases have been booked under Section 3 DPact, against bride and her family members but you are also requested to see Section 7 (3) of the act also.
You can also place reliance onto the case of Smt. Neera Singh Vs. Govt of (NCT of) Delhi, This case was in the year 2007 and after which a ciruclar of delhi police came into operation dealings with such cases. there have been instances of direction to register FIR against Bride and her family members in recent past from CJM Noida, and in District Courts Delhi.
However, very recently in October 2010, Delhi High Court has given a judment in which section 7(3) has been discussed in detail and it has been mentioned there that a Statement made by aggrieved person can not be used against her. A FIR is a statment hence the bar comes into operation. If you can provide me with more detail I can help you a little better.
regards.
