Ms Tanya Ward:

Approximately half of children in the care system are in voluntary care and an order, either an interim order or a care order, is not sought by Tusla before the courts. Guardians ad litemare appointed at the discretion of judges at present. They are only appointed in 56% of cases, according to one snapshot that the Child Care Law Reporting Project was able to establish.

The difference between those and voluntary care is the 50%. That is what you are getting at.
