A more thorough explanation:

Definition: The public-convenience-and-necessity standard is a commonly used criterion by government bodies to determine whether a specific request or project should be approved or granted. It is a measure of whether the proposed project or request is in the best interest of the public and whether it is necessary to meet the needs of the community.

Examples:

• A company wants to build a new power plant in a residential area. The government will use the public-convenience-and-necessity standard to determine whether the project should be approved. They will consider factors such as the potential impact on the environment, the health and safety of the community, and whether there are alternative energy sources available.
• A restaurant owner wants to serve alcohol in their establishment. The government will use the public-convenience-and-necessity standard to determine whether the request should be granted. They will consider factors such as the impact on the community, whether there are already enough establishments serving alcohol in the area, and whether the owner has a history of responsible alcohol service.

These examples illustrate how the public-convenience-and-necessity standard is used to evaluate whether a project or request is in the best interest of the public. The government considers various factors to determine whether the project or request is necessary and whether it will have a positive or negative impact on the community.
