Promissory Estoppel in relation to Retirement Benefits (Riingen vs. Financial vs. Western Union Financial Services, G.R. No. 252716, March 23, 2021)
Promissory estoppel may arise from the making of a promise, even though without consideration, if it was intended that the promise should be relied upon, as in fact it was relied upon, and if a refusal to enforce it would virtually sanction the perpetration of fraud or would result in other injustice. Promissory estoppel presupposes the existence of a promise on the part of one against whom estoppel is claimed. The promise must be plain and unambiguous and sufficiently specific so that the court can understand the obligation assumed and enforce the promise according to its terms.
