By withdrawing the passports, Norwegian authorities have managed to force mother and children back to Norway.
The Norwegian legislation about passports may be highly relevant in other cases too.
Lov om pass (passloven)av 1997-06-19-82
https://lovdata.no/dokument/NL/lov/1997-06-19-82I have not found any official translation.
From §5 abd §7 it seems clear that the authorities can refuse issue of a passport, and also that the validity of an existing passport can be withdrawn, if, for instance, somebody is wanted by the police for some crime.
In that connection, a question of importance for families who leave Norway to avoid Barnevernet confiscating their children, is what the basis of a "wanted" classification on the part of the authorities may be. The mother who escaped with her children to Malaysia, did this in violation of a legally binding decision already made.
But let us take a case of a family leaving in time, before they have violated any law, but Barnevernet nevertheless wants to command them home. It does not take much experience of how Norway makes use of Barnevernet to see the possibility that Barnevernet will also,
without any decision made by anybody but themselves, have the authority to make the police notify internationally that the family is "wanted", and accomplish this by means of revoking their passports.
It could for example be a family which Barnevernet had previously been in the process of "investigating" (read: building up a case against), and which Barnevernet now wants to "follow up in order to see how the children are doing".
IF the family has not in the meantime obtained citizenship in another country, making them totally independent of Norway.

"Rådet om å skaffe utenlandsk pass for seg selv og barna begynner å bli veldig relevant." (The recommendation to obtain foreign passports for oneself and the children is starting to be very, very relevant.)
