...surprised people are saying OSA will inhibit people from giving evidence to the child abuse enquiries. Surely (and I don't have the Act to hand and I am not a lawyer) there must be a caveat in the act for due legal process. (or maybe it is "convenient" to claim there isn't)
To my simple mind, the only people who might argue that are those that think the OSA is there to protect officials rather than secrets. And they would only think that if they had something to hide.
