Not before a judge.
This legal maxim is of latin origin meaning a legal proceeding outside the authority of the judge, that is, without a judge, with no proper presence, or without any legal jurisdiction. Any order or sentence passed by a court or tribunal, which does not possess the authority to try an accused of that particular offence, shall be in violation of the law of the land, not enforceable, and it would be termed as Coram non judice.
Since the case belonged to the jurisdiction of B, therefore, the order passed by A is “Coram non judice”.

Hear the other side
The maxim denotes the meaning “hear the other side”, which means no person should be unheard and both parties will be provided the opportunity of being heard. Justice will be given to both parties. Audi alteram partem is derived from the Latin phrase “audiatur et altera pars”. It also denotes the same meaning. The maxim aims to ensure fair play and justice to the person who is affected. The maxim also promotes the concept of “Natural Justice”.
Law will help only those who are vigilant.

One person who decides to maintain his/her silence during the statutory period, after the statutory period they cannot claim enforcement of the rights.
Where there is a right, there is a remedy.
This is a legal maxim, which means that where there is a right, there is a remedy. To get a legal remedy, a person should possess a legal right. Whenever the law gives a right to a person or prohibits an injury, then it also provides a remedy. So to sue in the court of law, one should establish his right and its violation.
