A more thorough explanation:

festinum remedium

Festinum remedium is a Latin term that means a speedy remedy. It was used in legal cases where the injured party was given redress without unnecessary delay. For example, in cases of dower or assize, festinum remedium was used to ensure that justice was served quickly.

One example of festinum remedium in action is in cases of dower. If a widow was entitled to a portion of her deceased husband's estate, festinum remedium would ensure that she received her rightful share without delay. Another example is in cases of assize, where festinum remedium would ensure that the injured party received compensation for damages without unnecessary delay.
