Healthy School Meals for All Program

The act refers 2 ballot issues to the voters at the November 2025 statewide election concerning funding for the healthy school meals for all program. Section 2 refers a ballot issue to the voters at the November 2025 statewide election to allow the state to retain and spend state revenue that would otherwise need to be refunded for exceeding the estimate in the ballot information booklet analysis for Proposition FF and to allow the state to maintain the increases in state taxable income established in Proposition FF that would otherwise need to be decreased. If voters reject the ballot issue, the state will both: Refund $12,430,388 to individuals who have a federal taxable income of $300,000 or more and claimed itemized or standard state income tax deductions greater than $12,000 for single tax return filers and $16,000 for joint tax return filers; and Adjust the limit on itemized deductions established in Proposition FF to a level that would have reduced the amount of income tax revenue attributable to these itemized deductions by $12,430,388. If voters approve the ballot measure: The state will not refund $12,430,388 to individuals who have a federal taxable income of $300,000 or more and claimed itemized or standard state income tax deductions greater than $12,000 for single tax return filers and $16,000 for joint tax return filers; and The increases in federal taxable income as a result of Proposition FF will stay at the levels established by Proposition FF. Section 3 refers a ballot issue to the voters at the November 2025 statewide election to allow the state to increase taxes by $95 million annually by increasing state taxable income to support the healthy school meals for all program. If voters approve the ballot issue: Income tax deductions for individuals who have a federal taxable income of $300,000 or more will be reduced from current levels to $1,000 for single filers and $2,000 for joint filers; and The state will allocate the additional revenue generated by the reduction in income tax deductions to the healthy school meals for all program. If voters reject the ballot issue, income tax deductions will not be reduced, and there will not be any additional revenue to be allocated to the healthy school meals for all program. In addition to the income tax changes and potential refunds that may result from voters approving or rejecting the ballot issues described in sections 2 and 3, the act also changes the healthy school meals for all program cash fund (fund) and healthy school meals for all programs. If voters approve the ballot issue submitted pursuant to section 2 and reject the ballot issue submitted pursuant to section 3, $1 million is transferred annually from the fund to local school food purchasing programs. If voters approve the ballot issue submitted pursuant to section 3, regardless of whether the voters approve the ballot issue submitted pursuant to section 2: The permissible distribution of local food purchasing grants is modified; Certain school food authorities are allowed to collaborate to implement advisory committees; The duties of an advisory committee are clarified; and The distribution of funds from the fund is changed so that the amounts distributed through local food purchasing grants for increasing wages or providing stipends for individuals whom the participating school food authority employs to directly prepare and serve food for school meals and through the local school food purchasing technical assistance and education grant program are modified based on the amount of money in the fund. NOTE: Certain provisions of the act are contingent on the results a measure concerning Proposition FF refunds or Proposition FF revenue increases being either approved or not approved by a majority of voters at the November 2025 statewide election.(Note: This summary applies to this bill as enacted.)

Forensic Science Integrity

The act defines "knowing misconduct" as a voluntary act or omission or series of acts or omissions consciously performed by a crime laboratory employee (employee) as a result of effort or determination in which the employee is aware that the employee's conduct is improper or deceptive and involves mishandling physical evidence or data or results, incorrectly performing forensic testing, presenting misleading or false results, concealing material information, or presenting false sworn testimony about evidence. The act defines a "significant event" as an act or omission by an employee that is a gross deviation from the standard operation procedures or accreditation requirements of the crime laboratory, or requirements in law that were applicable at the time of the act or omission of the employee, that could substantially negatively affect the integrity of the crime laboratory activities. The act requires an employee to report witnessed or discovered knowing misconduct or a significant event (collectively, "wrongful action") within 7 days of witnessing or discovering the wrongful action to the director of the crime laboratory (director) or to the employee's immediate supervisor, who shall report it to the director. A director who receives a report shall investigate the alleged wrongful action. As part of the investigation, the director must compile a list of all cases that the employee worked on. At the conclusion of the investigation, the director shall prepare a written final report. When an investigation is of alleged wrongful action in a pending case, the director shall notify each district attorney who has jurisdiction over the pending case about the investigation. At the conclusion of the investigation, if the investigation determines that the employee did not engage in wrongful action, the director shall deliver the final report to each district attorney who received notice of the investigation and to each district attorney who has jurisdiction over any case that was subject to investigation. If the investigation determines that the employee engaged in wrongful action, the director shall deliver the final report and all discoverable materials to each district attorney who has jurisdiction over any case that the employee worked on in an official capacity. If an investigation concerning wrongful action by a crime laboratory occurred after July 1, 2014, and before July 1, 2025, and the investigation resulted in criminal allegations filed against the employee or a sustained internal affairs action by the department supervising the employee, the director shall, as soon as practicable but no later than September 1, 2025, prepare a final report and provide the final report to all district attorneys with jurisdiction over any criminal case that is identified in the final report that is pending or has resulted in a conviction in that jurisdiction. Upon receipt of a notice from a director about an investigation into alleged wrongful action in a pending case, a district attorney shall notify the defendant in the case of the investigation. If the case involved a crime listed in the "Victim Rights Act", the district attorney shall also notify the victim about the alleged wrongful action, if the charges have been filed but the trial has not begun. A district attorney who receives a final report of an investigation that determines that a crime laboratory employee engaged in wrongful action in any case shall notify the defendant in that case, and each defendant whose case was reviewed as part of the investigation, of the determination of wrongful action. The act establishes a defendant's right to counsel in matters involving an employee's wrongful action and a right to investigate the wrongful action, to request discovery related to the wrongful action, and to seek post-conviction relief based on the wrongful action. The act permits a court to enter a protective order related to discovery requests. The act establishes a process for a defendant convicted in a case involving an employee's wrongful action to petition for post-conviction relief based on the wrongful action. If the defendant's petition for post-conviction relief asserts facts that, if true, demonstrate that a wrongful action was material to the case, the court shall decide the claim upon the merits after an evidentiary hearing. At the evidentiary hearing, the defendant has the burden to show that the employee committed the wrongful action and that the wrongful action is material to the case. If the defendant meets their burden, the court shall vacate the defendant's conviction and grant a new trial. The act makes all records related to an investigation criminal justice records and makes release of the records governed by the existing law governing criminal justice records; except that the custodian of a final report that concludes that a crime laboratory employee engaged in wrongful action may deny inspection of the report if there is an ongoing criminal investigation or criminal case. The act appropriates $140,433 from the general fund to the judicial department for use by the state courts. (Note: This summary applies to this bill as enacted.)

Voluntary Do-Not-Sell Firearms Waiver

The act establishes a process for a person to voluntarily waive the right to purchase a firearm (voluntary waiver). The Colorado bureau of investigation (bureau) in the department of public safety (department) shall deny a firearm transfer to the person while the voluntary waiver is in effect. The bureau shall develop an online portal (portal) for a person to electronically file for a voluntary waiver, update contact information, and revoke a voluntary waiver. The bureau is required to verify the filer's identity before accepting a voluntary waiver or revocation. The bureau shall enter a voluntary waiver into the national instant criminal background check system and any other federal or state computer-based systems used to identify prohibited purchasers of firearms. A person may revoke the voluntary waiver by filing for revocation with the bureau. The waiver remains in effect for 30 days after the bureau accepts the revocation. A person filing the voluntary waiver form may provide the name and contact information of a person who will be contacted if the person attempts to purchase a firearm while the voluntary waiver is in effect or if the filer revokes the voluntary waiver. The act prohibits a person from attempting to purchase a firearm while subject to a voluntary waiver. Attempting to purchase a firearm while subject to a voluntary waiver is a civil infraction, punishable by a maximum $25 fine. The voluntary waiver process and the prohibition on attempting to purchase a firearm while subject to a voluntary waiver are contingent on the department receiving $200,000 of gifts, grants, or donations to develop and operate the portal. The act permits the department to seek, accept, and expend gifts, grants, or donations for the portal. (Note: This summary applies to this bill as enacted.)

Firearm Serial Number Check Request Procedure

The act establishes a procedure allowing a federal firearms licensee (licensee) to request a firearm serial number check prior to purchasing a firearm from an individual and requires a local county sheriff's office or police department to complete the serial number check within 3 days after the request. The firearm serial number check must include information regarding whether the firearm is stolen, lost, or is involved in an open criminal investigation. If a licensee is located within incorporated city limits, they must request the firearms serial number check from the police department within its city limits. If a licensee is located in an unincorporated part of the county, they must request a firearms serial number check from the sheriff's department of the county in which it is located. A police department or sheriff's office may charge a reasonable fee to complete the firearm serial number check. The act also allows a licensee to perform a firearm serial number search themself if the federal government allows the licensee access to the federal government's firearm tracing program. The licensee is still subject to the reporting requirements if the licensee performs the firearm serial number search themself. The act imposes a penalty on a licensee if the licensee fails to file a report with law enforcement when the licensee reasonably believes, knows or should know, or becomes aware that a person sold or attempted to sell a firearm that is stolen, lost, or involved in an open criminal investigation.
