Answer:
Promissory Estoppel
Explanation:
Promissory estoppel states that a person who has promised to fulfill a contract cannot go back on the promise even if consideration was yet to be given. The affected party can file suit against the party who refused to fulfill his promise and can claim damages.
Promissory estoppel was created to protect parties under contract from incurring damages due to backing off by the other party. Here, Suzy can sue George on the basis of promissory estoppel.
