ON THIS DAY in 1991, the NSW Adoption Information Act 1990 came into force.  The Act granted adoptees and relinquished parents the right to access adoption information and express interest in contact or veto contact.  The Act was repealed by the Adoption Act 2000 which carried over the 1990 provisions.
