Sovereign Immunity
Sovereign immunity is a legal doctrine that protects government entities and officials from being sued without their consent. In this case, it means that the Airport Board and Corporation cannot be held liable for negligence related to the air crash because they are performing governmental functions.
Governmental Function
A governmental function refers to activities that are essential to the administration and governance of public affairs, such as maintaining transportation infrastructure. The court determined that providing and maintaining the airport falls under this category.
Municipal Corporations vs. Government Agencies
Municipal corporations are local government entities like cities, which can be held liable for negligence outside their legislative roles. In contrast, government agencies like the Airport Board perform state functions and are typically immune from such liability.
Two-Pronged Test
Originating from the Berns case, the two-pronged test assesses whether an entity is controlled by the state and performs governmental functions to determine its eligibility for sovereign immunity.
Alter Ego Doctrine
This doctrine holds that a separate corporate entity is essentially an extension of the parent entity, thereby inheriting its immunity. The Airport Corporation was deemed an alter ego of the Airport Board, maintaining its protected status.
