1. What Passport Authorities have done is that they are following "civil consequence" before passing Order on "impounding" i.e. giving you opportunity to be heard.
2. Court cannot "impound" passport even under S. 104 CrPC.
3. Even if police has "seized" Passport wide power under S. 102 CrPC then thereafter the police must send it along with a letter to the Passport Authority clearly stating that the seized passport deserves to be "impounded" for one of the reasons mentioned in S. 10 (3) of the Passport Act. Since impounding of a passport has civil consequences, the passport authority must give an opportunity of hearing to the person concerned before impounding his passport. Ref.: State of Orissa Vs. Binap ani Dei [AIR 1967 SC 1269]
4. You should take along with you the Child Jurisdiction True Copy details. Her GWA petition and True Copy of your GWA petition for clarifying the 'root" of malice read with malafide intention the complainant approached Passport Authorities directly "by passing" Jurisdiction of a competent Court and or even her Jurisdiction Police Station to lodge such "formal protest" read with "impounding" frivilous plea ! I am not sure if you can do / say so much based on my experience handling your past replies.
