Colo. Rev. Stat. § 24-30-2111
A person shall not be compelled to disclose a program participant's actual address or any unique identifying information related to the participant's residence, work, or school during the discovery phase of or during a proceeding before a court of competent jurisdiction or administrative tribunal unless the court or administrative tribunal finds, based upon a preponderance of the evidence, that the disclosure is required in the interests of justice and that the potential harm to the program participant is substantially outweighed by the public interest in the disclosure and that no other alternative would satisfy that necessity. A court or administrative tribunal may seal the portion of any record that contains a program participant's actual address. Nothing in this section prevents a state or local government agency, in its discretion, from using a program participant's actual address in any document or record filed with a court or administrative tribunal if, at the time of filing, the document or record is not a public record.
C.R.S. § 24-30-2111
This section is similar to former § 24-21-211 as it existed prior to 2011.
