ESTOPPEL:
"Finally, petitioner cannot oppose the renewal of the lease because of estoppel. Our following disquisition in Kalalo v. Luz[55] is relevant herein:
Under Article 1431 of the Civil Code, in order that estoppel may apply the person, to whom representations have been made and who claims the estoppel in his favor must have relied or acted on such representations. Said article provides:
“Art. 1431. Through estoppel an admission or representation is rendered conclusive upon the person making it, and cannot be denied or disproved as against the person relying thereon.”
An essential element of estoppel is that the person invoking it has been influenced and has relied on the representations or conduct of the person sought to be estopped, and this element is wanting in the instant case. In Cristobal vs. Gomez, this Court held that no estoppel based on a document can be invoked by one who has not been misled by the false statements contained therein. And in Republic of the Philippines vs. Garcia, et al., this Court ruled that there is no estoppel when the statement or action invoked as its basis did not mislead the adverse party. Estoppel has been characterized as harsh or odious, and not favored in law. When misapplied, estoppel becomes a most effective weapon to accomplish an injustice, inasmuch as it shuts a man's mouth from speaking the truth and debars the truth in a particular case. Estoppel cannot be sustained by mere argument or doubtful inference; it must be clearly proved in all its essential elements by clear, convincing and satisfactory evidence. No party should be precluded from making out his case according to its truth unless by force of some positive principle of law, and, consequently, estoppel in pais must be applied strictly and should not be enforced unless substantiated in every particular.
The essential elements of estoppel in pais may be considered in relation to the party sought to be estopped, and in relation to the party invoking the estoppel in his favor. As related to the party to be estopped, the essential elements are: (1) conduct amounting to false representation or concealment of material facts; or at least calculated to convey the impression that the facts are otherwise than, and inconsistent with, those which the party subsequently attempts to assert; (2) intent, or at least expectation that his conduct shall be acted upon by, or at least influence, the other party; and (3) knowledge, actual or constructive, of the real facts. As related to the party claiming the estoppel, the essential elements are (1) lack of knowledge and of the means of knowledge of the truth as the facts in questions; (2) reliance, in good faith, upon the conduct or statements of the party to be estopped; (3) action or inaction based thereon of such character as to change the position or status of the party claiming the estoppel, to his injury, detriment or prejudice.[56] (Emphases ours.)."
