As I have noted in Can a person get passport during pendency of criminal case?, it is not permissible to have two passports at the same time and it is an offence. However, also see, Travelling to two opposing countries – requirement for 2 passports.
Please note that under the provisions of the Passport Act, 1967, one of the situations in which the passport authority may impound or revoke a passport or travel document is if the passport or travel document was obtained by the suppression of material information or on the basis of wrong information provided by the holder of the passport or travel document or any other person on his behalf. It is also provided that if the holder of such passport obtains another passport the passport authority shall also impound or cause to be impounded or revoke such other passport.
While you have not mentioned the full facts, it appears that the passport authority might have taken possession of your passport(s) on the suspicion that you had obtained two passports by the suppression of material information or on the basis of wrong information provided. You’ll have to ascertain the correct factual position from the concerned passport authority. If the authority has already passed or is about to pass an order to impound or revoke your passport(s), you may have to challenge such decision before the appropriate court by justifying why and how you came to have two passports.
