A more thorough explanation:

Definition: A law that is not based on natural principles, but is created solely by the decision of the government or legislature. This type of law can be changed or repealed at any time.

Example: In some countries, the government has the power to pass laws without any input from the citizens. These laws may not be based on any moral or ethical principles, but are simply created to maintain the government's power. For example, a government may pass a law that restricts freedom of speech or assembly, even if there is no legitimate reason for doing so.

Explanation: The example illustrates how a law can be arbitrary if it is created solely for the purpose of maintaining power, rather than being based on principles of justice or fairness. Such laws can be changed or repealed at any time, which means that citizens may not have any protection against government abuse of power.
