How does Promissory Estoppel Apply in Legal Circumstances?

Under what circumstances would promissory estoppel take effect?

a. Gia relied on Alvin’s promise to her detriment and Alvin should have known Gia would rely on it.

b. Gia relied on Alvin’s promise to her detriment.

c. Gia’s reliance on Alvin’s promise was foreseeable.

d. Alvin knew Gia would rely on his promise.

e. Gia relied on Alvin’s promise which Alvin knew she would do.

Final answer:

Promissory estoppel would apply in the scenario where Gia detrimentally relied on Alvin's promise, and Alvin should have known she would do so. The principle of promissory estoppel requires both detrimental reliance and the foreseeability of that reliance by the promisor.

Explanation:

Promissory estoppel is a legal principle that a promise is enforceable by law when a party who relies on that promise suffers a detriment due to its reliance and the promisor should have foreseen that the promisee would rely upon it. In the given scenario, promissory estoppel would take effect if Gia relied on Alvin’s promise to her detriment and Alvin should have known Gia would rely on it. This is because for promissory estoppel to take effect two conditions must be met; first, there was reliance on the promise, and secondly, this reliance was detrimental to the party relying on the promise (Gia in this case), and this reliance was foreseeable by the promisor (Alvin in this case).
