A more thorough explanation:

A short-cause trial is a type of court case that requires little time to try, usually half a day or less. It is also known as a short-cause under cause(3).

For example, a landlord may file a short-cause trial against a tenant who has not paid rent for several months. The trial would be brief and would only focus on the issue of unpaid rent.

Short-cause trials are used when the case is straightforward and does not require a lot of evidence or testimony. They are often used in small claims court or for minor legal disputes.
