The Two Doctrines

Promissory EstoppelStops the government from going back on a clear promise someone reasonably relied on.
Legitimate ExpectationLets a person challenge a decision that breaks a settled past practice or a clear promise.
No strict rightLegitimate expectation applies even without a strict legal right to the outcome.
Main guaranteeLegitimate expectation mainly gives a right to a fair hearing, not an automatic right to win.
So whatBoth protect reasonable reliance on the government’s word — but neither guarantees a win, only a fair look.

Scope and Limits

Against the StateBefore 1968, promissory estoppel did not apply to the government in India at all.
Now it doesThe doctrine now binds the government to its own promises and conduct.
Fairness, not outcomeThe guarantee is procedural fairness, not a guaranteed favourable result.
So whatThese doctrines limit the State’s power to renege, but not the State’s right to decide.

Why the State’s Word Is Held

FairnessEstoppel stops the State from reneging on a promise another reasonably relied on.
TrustLegitimate expectation protects a settled practice people have come to count on.
