Any file may be made available to those who have a legal right to see it, and any decision on access by researchers is made in the spirit of the Code of Practice on Access to Scottish Executive Information introduced on 1 July 1999.It is the policy of the Scottish Executive that as few files as possible should be subject to a "closure" period of more than thirty years, and a programme carried out in 1995 to examine all files in this category ensured that only very sensitive, mainly personal ones, are still not openly accessible.Policy in this whole area will be reviewed in the context of the forthcoming Freedom of Information legislation.
