A more thorough explanation:

Definition: Tempestive (tem-pes-tiv) is an adjective used in Scots law to describe something that is timely or timeous.

1. The payment was made in a tempestive manner, ensuring that the contract was fulfilled on time.

2. The lawyer filed the appeal in a tempestive manner, meeting the deadline set by the court.

In the second example, the lawyer filed the appeal within the deadline set by the court, which is necessary to ensure that the appeal is considered. In the third example, the delivery of the goods was not timely, causing a delay in the project.
