Acquiescence is a legal term used to describe an act of a person in knowingly standing by without raising any objection to infringement of his rights, when someone else is unknowingly and honestly putting in his resources under the impression that the said rights actually belong to him. Consequently, the person whose rights are infringed cannot anymore make a claim against the infringer or succeed in an injunction suit due to his conduct. The term is most generally, "permission" given by silence or passiveness. Acceptance or agreement by keeping quiet or by not making objections.
