The Scottish government has proposed extending freedom of information laws to cover private firms that carry out public sector projects, including prison operators and building contractors.
Currently, all public authorities are subject to legislation that provides transparency to the public over the quality of service provided, as well as ensuring value for money.
The new plans, which would be revised to include contractors involved in the construction of schools and hospitals, have been earmarked for formal consultation by MSPs.
The law may also be extended to include the Association of Chief Police Officers in Scotland, Glasgow Housing Association, trusts set up by local councils to provide leisure, sport or cultural services and the firms which operate and maintain trunk roads.
However, CBI Scotland said an expansion to the current law is unnecessary and would increase the cost of services.
Parliamentary Business Minister Bruce Crawford said: “It is important that organisations who deliver key public services for the people of Scotland operate transparently so the public can be reassured we are getting high-quality services and value for money.”
