A more thorough explanation:

Definition: In Scots law, the hour of cause refers to the time at which a trial is scheduled to begin.

• The hour of cause for the trial is 10:00am.
• The judge reminded the parties involved to be present in court at the hour of cause.

These examples illustrate that the hour of cause is a specific time set for the start of a trial in Scots law. It is important for all parties involved to be present at this time to ensure that the trial can proceed as scheduled.
