AN ACT to amend Tennessee Code Annotated, Title 5; Title 6; Title 38 and Title 68, relative to fire investigation.

Summary

HB1870 revises Tennessee law governing fire investigations and the authority of fire investigators to act in arson-related cases. The bill amends Tennessee Code Annotated § 68-102-127 to clarify that the commissioner of commerce and insurance and the commissioner’s deputies may exercise police powers, including arrest authority, in cases of arson or suspected arson only when the individual holds current POST certification. It also authorizes municipal and county fire investigators to exercise similar police powers when they have been properly authorized by their fire department leadership and hold current POST certification. The bill further preserves the ability of these officials to investigate the cause and origin of fires even if they do not have POST certification, so long as they are not exercising police powers. It creates a grandfathering and phase-in structure for existing investigators: those serving on January 1, 2027, who were hired before January 1, 2021, are exempt from the POST requirement, while those hired on or after January 1, 2021, must comply by January 1, 2030. The bill also directs the POST commission to issue certificates of compliance to qualifying fire investigators beginning January 1, 2028, provided they meet police officer employment qualifications and complete recruit and annual in-service training.

Impact

The bill amends Titles 38 and 68 of the Tennessee Code to formalize training and certification requirements for fire investigators who exercise police powers in arson investigations. It expands or clarifies the role of POST certification in determining who may make arrests or otherwise act with law-enforcement authority, while preserving non-police investigative functions for uncertified personnel. The measure affects the commissioner of commerce and insurance, municipal fire investigators, county fire investigators, and the POST commission, and it establishes transition deadlines and exemptions for current employees.

Sentiment

The available voting history suggests broad support for the bill. It received a 3-0 favorable recommendation in the House Public Service Subcommittee and a 19-1 favorable recommendation in the House State & Local Government Committee. No committee transcript is provided, but the strong vote margins indicate the measure was generally viewed positively as a technical or administrative update to fire-investigation authority and training standards.

Contention

The main policy issue appears to be whether fire investigators should be required to obtain POST certification before exercising police powers such as arrest authority. Support for the bill likely centers on standardizing training, improving accountability, and clarifying legal authority in arson cases. Any concern would likely come from agencies or personnel affected by the new certification mandate, especially those hired after January 1, 2021, who must meet the requirement by 2030, but the bill mitigates that concern through grandfathering and a delayed compliance period.
