A quick definition of peremption:

Peremption is a legal term that refers to a specific period of time set by the law for a person to exercise their right. If the right is not used during this time, it will be lost forever. Unlike prescription, which only bars a specific remedy, peremption bars the entire legal action. This means that if the time limit for peremption has passed, the person can no longer pursue their legal claim.

For example, if a person has a right to file a lawsuit against someone, but they wait too long to do so, they may lose their right to sue. This is because the law has set a time limit for them to file the lawsuit, and if they do not do it within that time, their right to sue will be extinguished.

Peremption is an important concept in the legal system, as it helps to ensure that legal disputes are resolved in a timely manner. It also helps to prevent people from holding onto their legal rights indefinitely, which could lead to unfairness and injustice.
