F. Addressing government suits against disclosure.

A public records custodian may file an application with a district court seeking an order permitting him or her to restrict or deny access to the records if (s)he establishes that although no specific statutory exemption from disclosure applies, public disclosure of the particular records would cause "substantial injury to the public interest." C.R.S. section 24-72-204(6); see also Civil Service Comm'n v. Pinder, 812 P.2d 645 (Colo. 1991)(to establish "substantial injury to public interest" to warrant nondisclosure, custodian must demonstrate that the particular circumstances of the case are such that the legislature could not have anticipated them); Bodelson v. Denver Publishing Co., 5 P.3d 373 (Colo. App. 2000)(same). Alternatively, the custodian may apply to a district court for an order permitting him or her to restrict disclosure if the custodian "is unable, in good faith, after exercising reasonable diligence and after reasonable inquiry, to determine whether disclosure of the public record is prohibited" by the statute. C.R.S. section 24-72-204(6).
