Joint Resolution Amending Rules of Evidence to Address Machine-Generated Evidence
HJR 26 amends Utah's Rules of Evidence to establish new standards for admitting evidence generated by automated systems (like AI or algorithms) that make inferences or predictions. It requires such evidence to meet four criteria for admissibility: it must help the court understand the case, be based on sufficient facts, use reliable methods, and apply those methods correctly to the facts. This rule specifically excludes basic measuring devices (like speedometers or thermometers) from these requirements. The bill affects Utah courts and legal proceedings involving machine-generated evidence, ensuring such evidence meets reliability standards before being used in trials.

MODERATE
This bill formally enacts a new rule (Rule 707) into the Utah Rules of Evidence to regulate how courts handle evidence produced by machines. It defines specific terms like 'machine-generated evidence' and sets strict criteria for when such evidence can be admitted in court without an expert witness, ensuring it is reliable and based on sufficient data. The bill also clarifies that simple measuring devices are exempt from these rules.
Scope change
The bill's scope is now formally established as a permanent addition to state law, moving from a draft proposal to an enrolled, effective resolution.
DEFINITION
Added formal legal definitions for 'machine-generated evidence' (systems that make inferences) and 'simple scientific instrument' (devices that only measure data directly).
REQUIREMENT
Established a four-part test courts must use to admit machine-generated evidence without an expert: it must help the jury, be based on sufficient data, use reliable methods, and be reliably applied to the case.
ELIGIBILITY
Clarified that the new rule applies when evidence is entered directly or supported by lay testimony, but explicitly excludes simple scientific instruments.
TECHNICAL
Converted the text from a draft legislative proposal format to the official enrolled copy format used for final passage.
