“The principle of estoppel by conduct is based on the public policy that says that there must be an end to litigation. Its aim is, not only to hold a party to his undertaking that he will no longer insist on either his right to appeal or the accrued right or obligation from the judgment, but also not to allow a person benefit from his prevarication”.
