A more thorough explanation:

nul agard

In a legal case where someone is trying to enforce an arbitration award on an arbitration bond, nul agard means that the defendant is denying that the award exists. It comes from the Law French phrase "no award." This is different from AGARD, which is a plea that admits the existence of the award but argues that it is invalid for some reason.

Example 1: In a case where a company is trying to collect money from a former employee based on an arbitration award, the employee might file a nul agard plea if they believe that the award was never actually made.

Example 2: If the employee believes that the award was made but that it was unfair or invalid for some reason, they might file an AGARD plea instead.

These examples show how nul agard is used in a legal context to deny the existence of an arbitration award, while AGARD is used to argue that the award is invalid for some reason.
