fiat

FEE-aht/ˈfiːɑːt/

An order issued by someone with authority.

The judge's fiat compels the protesting participant to surrender her keys to the officer.

An official decision imposed through a judge's unmistakable command and an officer's immediate enforcement: a protesting participant reluctantly surrenders her keys.
Etymology

From fieri, “to be done,” fiat meant “let it be done.” Its use in proclamations turned that expression of authority into a noun for an official order.
