A more thorough explanation:

Definition: Jus actus is a Latin term used in Roman law that refers to an act or action that has been done. It can also refer to an act of Parliament that has been passed by both houses but not yet approved by the monarch. In Roman law, it can also refer to a servitude for driving cattle or a carriage across another's land.

• When John signed the contract, it was considered a jus actus.
• The bill was passed by both houses of Parliament, but it was not yet a jus actus until it was approved by the monarch.
• In Roman law, a jus actus could be granted to allow someone to drive their cattle across another's land.

These examples illustrate how jus actus can refer to a variety of actions or legal situations, from signing a contract to passing a bill in Parliament to granting a servitude for driving cattle. In each case, jus actus refers to something that has been done or granted, but may not yet be fully approved or legally binding.
