They have have made a similar legal complaint against the DA in The Netherlands.
The Dutch branch and some KH were raided last year too, in search for evidence related to child sex abuse accusations.
Dutch JW have now started a court case because they claim these raids are a violation of the clergy-penitent privilege.
On the first court day JW asked for a stay of proceedings, because they needed to study the response that the DA's office wrote to the JW complaint.
So far I'm not aware they have scheduled a new court date yet.
