nullité des actes juridiques

"Nullité des actes juridiques" refers to the legal concept that a contract or agreement is considered invalid from the start, meaning it has no legal effect. This can happen if the act was created under conditions that violate the law, lacked consent, involved fraud, or was made by someone not authorized. When an act is declared null, it is as if it never existed legally, and parties may need to return what they received. Nullity can be either absolute (affecting the public interest) or relative (affecting only certain individuals).
