The doctrine of estoppel is a legal principle aimed at preventing injustice by prohibiting a person from going back on their word when their representation or conduct has induced reliance to the detriment of another party. Rooted deeply in the concepts of equity, justice, and fairness, this doctrine ensures that individuals act consistently in their dealings, fostering trust and accountability in legal and social relationships.

Definition and Scope of the Doctrine

Estoppel is derived from the Latin word "stoppare," meaning to prevent or bar. The doctrine is primarily enshrined in Section 115 of the Indian Evidence Act, 1872, which states:


"When one person has, by his declaration, act or omission, intentionally caused or permitted another person to believe a thing to be true and to act upon such belief, neither he nor his representative shall be allowed, in any suit or proceeding between himself and such person or his representative, to deny the truth of that thing."


Thus, the doctrine prevents a party from reneging on their previous statements, assurances, or conduct that led the other party to rely on them.

Principles of Equity, Justice, and Fairness

The doctrine of estoppel aligns closely with the principles of equity, justice, and fairness, which are fundamental to ensuring ethical conduct and the prevention of exploitation or harm.

Principle of Equity

• Equity seeks to provide remedies where strict legal rules may fall short of ensuring justice.
• Estoppel operates to balance the scales where one party has relied on another's representations to their detriment. By enforcing consistency in words and actions, it upholds fairness between the parties.
• Example: If a landlord allows a tenant to believe that a lease will be renewed and the tenant makes significant investments in the property based on this belief, the landlord may be estopped from denying the renewal.

Principle of Justice

• Justice demands that individuals be held accountable for their actions or representations, particularly when others have relied on them.
• By barring a party from acting contrary to their prior representations, the doctrine ensures justice for the party who acted in good faith based on such representations.
• Example: In a partnership, if one partner assures another of specific profits and induces them to contribute more capital, they cannot later deny the assurance if the partner acted on it.

Principle of Fairness

• Fairness underpins the ethical aspect of human conduct, ensuring that no party suffers harm due to the deceit or inconsistency of another.
• The doctrine discourages individuals from exploiting others by creating a framework of accountability, promoting fair dealing and mutual respect.
• Example: In employment, if an employer assures an employee of a promotion and the employee takes actions based on this promise, fairness demands that the employer fulfills their commitment.

Types of Estoppel

The doctrine of estoppel manifests in various forms, each reflecting the principles of equity, justice, and fairness:

• Promissory Estoppel:
  • Prevents a party from reneging on a promise that has been relied upon by another, even if no formal contract exists.
  • Example: If a government authority promises tax benefits to a company for setting up an industry and the company acts on it, the authority cannot withdraw the benefits later.
• Estoppel by Conduct:
  • Bars a party from asserting a fact contrary to their previous conduct.
  • Example: A person who consistently allows their neighbor to use a pathway through their property cannot later claim trespass.
• Estoppel by Representation:
  • Prevents denial of a fact represented as true, leading another party to act upon it.
  • Example: A seller who presents themselves as the owner of goods cannot later deny ownership if the buyer relied on this representation.
• Estoppel by Record (Res Judicata):
  • Prohibits re-litigation of matters already decided by a competent court.

The courts have consistently upheld the doctrine of estoppel as a tool for ensuring equity, justice, and fairness:

  • This landmark case established the principle of promissory estoppel. The court held that a party cannot withdraw a promise if it has been relied upon to the detriment of another.

  • The Supreme Court reiterated that promissory estoppel is based on the principles of equity and good conscience.
• Municipal Corporation of Delhi v. Gurnam Kaur (1989):

Limitations and Exceptions

• Misrepresentation or Fraud:
  • Estoppel cannot be invoked to perpetuate a fraud or misrepresentation.
• Statutory Prohibition:
  • It cannot override statutory provisions or public policy.

Conclusion
The doctrine of estoppel embodies the principles of equity, justice, and fairness, ensuring that individuals act with integrity and accountability in their dealings. By preventing parties from contradicting their previous representations or actions, it protects the rights and interests of those who rely on such conduct in good faith. While its application is subject to certain limitations, the doctrine remains a vital tool for fostering ethical conduct and mitigating unfair advantage in legal and social relationships. Through its emphasis on fairness and justice, estoppel continues to uphold the moral fabric of legal systems worldwide.
