Immunity of Governmental Entity
The TGTLA generally states that all governmental entities shall be immune from suit for any injury which may result from the activities of such governmental entities "[e]xcept as may be otherwise provides in this chapter." T.C.A. § 29-20-201(a)

Situations Where Immunity of Governmental Immunity is Removed
Governmental entities are not immune from suit for injuries resulting from an employee’s negligent operation of a motor vehicle or other equipment while in the scope of his or her employment. However, this provision does not repeal T.C.A. § 55-8-101, T.C.A. § 55-8-108, or T.C.A. § 55-8-132, which relate to operating authorized emergency vehicles. The immunities provided by these sections are expressly continued. T.C.A. § 29-20-202.

Governmental entities are not immune from suit for any injury caused by a defective, unsafe, or dangerous condition of any street, alley, sidewalk, or highway owned and controlled by the governmental entity, including any traffic-control devices. This provision does not apply unless constructive or actual notice to the governmental entity of the condition is alleged and proved. T.C.A. § 29-20-203.

Governmental entities are not immune from suit for any injury caused by the dangerous or defective condition of any public building, structure, dam, reservoir, or other public improvement owned and controlled by the governmental entity. Immunity is not removed for latent defective conditions, nor shall this section apply unless constructive or actual notice to the governmental entity of the condition is alleged and proved. T.C.A. § 29-20-204.

Governmental entities may also be sued for injury proximately caused by a negligent act or omission of an employee within the scope of his employment, unless the injury arises or results from:

• the exercise or performance or failure to exercise or perform a discretionary function, whether or not the discretion is abused;
• false imprisonment pursuant to a mittimus from a court, false arrest, malicious prosecution, intentional trespass, abuse of process, libel, slander, deceit, interference with contract rights, infliction of mental anguish, or invasion of privacy, or civil rights;
• the issuance, denial, suspension, or revocation or failure or refusal to issue, deny, suspend, or revoke any permit, license, certificate, approval, order, or similar authorization;
• the failure to make an inspection or making an inadequate or negligent inspection of any property.
• the institution or prosecution of any judicial or administrative proceeding, even if malicious or without probable cause;
• misrepresentation by an employee, whether or not such is negligent or intentional;
• riots, unlawful assemblies, public demonstrations, mob violence, or civil disturbances
• the assessment, levy, or collection of taxes
• Y2K-related computer failures occurring before January 1, 2005; or
• any loss, damage, injury, or death arising from COVID 19 "unless the claimant proves by clear and convincing evidence that the loss, damage, injury, or death was proximately caused by an act or omission by the entity or its employees constituting gross negligence.

T.C.A. § 29-20-205.

In sum, the ten exceptions listed above are types of claims for which governmental entities retain immunity.

Waiver of Immunity by Governmental Entity
A governmental entity may waive its immunity from suit only by express provisions or endorsement of a policy or contract of insurance authorized by this law to cover its liabilities. The law also provides that any contract of insurance to cover liabilities under federal law shall not be construed or deemed to be a waiver of such immunity. T.C.A. § 29-20-404(a).

Immunity of Members of Boards, Commissions and Other Governing Bodies
T.C.A. § 29-20-201(b) grants immunity from suit to all members of boards, commissions, agencies, authorities, or other governing bodies of governmental entities arising from their affairs except for willful, wanton, or grossly negligent acts.
