What type of act involves carrying out duties strictly as required without choice?

Ministerial acts are those actions performed by an individual or a government official that are carried out in a prescribed manner without any discretion or personal judgment. These acts are defined by established practices or law, meaning the individual is required to follow specific procedures or guidelines.

In the context of fire inspections, for example, a fire marshal may be required to inspect certain types of buildings at designated intervals, complying strictly with regulatory standards and protocols. There is no allowance for personal discretion in such duties; they must be completed as dictated by the law or policies governing fire safety.

This contrasts with discretionary acts, where the individual has the flexibility to make decisions based on their judgment, and voluntary acts, which are performed out of free will and choice. Subrogated acts involve legal situations concerning rights and duties, particularly in terms of insurance and debt claims, and are not relevant to the context outlined in the question.
