MODERATE
This bill was amended to add protections for confidential antitrust pre-merger notification information. The changes expand what the Attorney General cannot disclose and clarify exemptions under the Colorado Open Records Act, while allowing disclosure in specific legal proceedings where the merger is relevant.
Scope change
The bill's scope was expanded to include additional categories of confidential information that are protected from public disclosure under the Colorado Open Records Act.
REQUIREMENT
Added five specific categories of confidential information that the Attorney General may not disclose, including Hart-Scott-Rodino forms, additional documentary materials, and merger proposals.
ENFORCEMENT
Clarified that the protected information is exempt from disclosure under the Colorado Open Records Act, Part 2 of Article 72 of Title 24.
Established an exception allowing the Attorney General to disclose protected information in administrative proceedings or judicial actions if the proposed merger is relevant to the case, subject to a protective order.
TECHNICAL
Removed committee listings and formatting elements, changing the document status from 'Revised' to 'Preamended' to reflect that committee amendments are not yet adopted.
