Which doctrine may preclude a municipality from asserting a right due to its action or inaction?

• A. Equitable estoppel
• B. Res judicata
• C. Stare decisis
• D. Sovereign immunity

Answer: (A)

Equitable estoppel is tested here. It prevents a party from asserting a right if its own words or conduct led someone else to rely on them to their detriment, making it unfair to permit the party to go back on its position. When a municipality acts or stays silent in a way that a member of the public reasonably relies on, such as promising or implying that a permit, policy, or future action will be honored, and the public takes actions in reliance (investing money, changing position, etc.), fairness may require the government to be bound by that representation. The key elements are a representation or conduct by the government, actual reliance by others, and resulting harm or change in position, with the inequity of allowing the government to contradict its prior stance. Res judicata, by contrast, deals with final judgments and preventing relitigation of the same claim after a decision has been made. Stare decisis concerns following established precedents in court. Sovereign immunity protects the government from being sued in many contexts; it concerns the ability to sue rather than precluding the government from asserting a right due to its own conduct.
