Information and records maintained by the pretrial services agency which have not been disclosed in open court during a court proceeding shall not be released by the pretrial services agency to any individual or organization, other than any employee of a Probation and Court Service Department, without the express permission of the interviewed or supervised person at or near the time the information is to be released. An individual shall have access to all information and records about himself or herself maintained by or collected by the pretrial services agency. The principle of confidentiality shall not bar a pretrial services agency from making its data available for research purposes to qualified personnel, provided that no records or other information shall be made available in which individuals interviewed or supervised are identified or from which their identities are ascertainable.
