"The judicial or administrative authority, even where the proceedings have been commenced after the expiration of the period of one year referred to in the preceding paragraph, shall also order the return of the child, unless it is demonstrated that the child is now settled in its new environment."
"There is only one exception. Where the words or actions of the wronged parent clearly and unequivocally show and have led the other parent to believe that the wronged parent is not asserting or going to assert his right to the summary return of the child, and are inconsistent with such return, justice requires that the wronged parent be held to have acquiesced."
