ALBANY – The activities of volunteers tapped by Family Court judges to advocate for foster children are significantly restricted by confidentiality requirements, a state appeals court ruled.

The Appellate Division, Third Department, decided that a Court Appointed Special Advocate (CASA) in Ulster County may not gain access to either the state’s registry of abused or neglected children or to information about the mental-health services received by the children in the course of the CASA’s monitoring of a foster-care case involving four children.
