A more thorough explanation:

EX RIGORE JURIS

Ex rigore juris is a Latin term that means "according to the strictness of the law".

1. In a criminal case, the judge must follow ex rigore juris and apply the law strictly, without any leniency.

2. The contract clearly stated that any breach would result in termination, and the employer acted ex rigore juris when they fired the employee for violating the terms.

Ex rigore juris means that the law must be applied strictly, without any exceptions or leniency. In the examples given, the judge in the criminal case must follow the law strictly and not consider any personal circumstances or emotions. Similarly, the employer in the second example had to follow the contract strictly and terminate the employee for violating the terms, without any consideration for the employee's situation.
