A more thorough explanation:

Definition: Jure imperii is a Latin term that means "by right of sovereignty." It refers to the public acts that a nation undertakes as a sovereign state. These acts are usually immune from legal action or liability in a foreign country.

For example, if a foreign country wants to sue another country for an action that was taken by the government of that country, they cannot do so under the principle of jure imperii. This is because the government was acting as a sovereign state and is therefore immune from legal action.

Another example is if a foreign country wants to collect taxes from a company that is owned by the government of another country. The company would be considered an act of jure imperii and would be immune from taxation.

These examples illustrate how jure imperii protects a country's sovereignty and allows it to carry out its public acts without fear of legal action or liability in foreign countries.
