Understanding Estoppel in Legal Proceedings: A Comprehensive Overview


Estoppel, often referred to as a “rule of evidence,” is a fundamental principle in the realm of law that restricts the introduction of certain evidence under specific circumstances. This blog post aims to provide a clear and comprehensive understanding of estoppel in legal proceedings. We will explore its various forms, its scope, general conditions, and when it does not apply. Throughout this discussion, we will reference relevant legal provisions and cases to support our analysis.

Estoppel: A Rule of Evidence

Estoppel, as defined by Section 115 of the Indian Evidence Act, 1872, occurs when one person intentionally causes another to believe something to be true and act upon that belief. In such cases, neither the person nor their representative is allowed to deny the truth of that thing in any legal proceeding between them and the other party or their representative.

Illustration: Let’s consider a scenario where A falsely leads B to believe that certain land belongs to A, inducing B to buy it. Later, A seeks to set aside the sale, claiming they had no title at the time. Under estoppel, A cannot deny their title in the legal proceedings.

This doctrine of estoppel is not a rule of equity but rather a rule of evidence applied in courts of law.

Forms of Estoppel

Estoppel takes various forms under different circumstances:

  • Estoppel of Tenant and Licensee (Section 116): During a tenancy, a tenant cannot deny their landlord’s title to the property. Similarly, a person who enters another’s property with their license cannot later deny that person’s title to the property.
  • Estoppel of Acceptor of Bill of Exchange, Bailee, or Licensee (Section 117): An acceptor of a bill of exchange cannot deny the drawer’s authority to draw or endorse it. Likewise, a bailee or licensee cannot deny their bailor or licensor’s authority at the commencement of the bailment or license.
  • Estoppel by Deed: This form of estoppel rests on the principle that written evidence is more conclusive than oral evidence. It applies when parties rely on written agreements.
  • Estoppel in Res Judicata: When one person induces another to alter their position based on a representation, the representor is estopped from later contradicting that representation in any subsequent litigation.

Scope of Estoppel

Estoppel’s scope has evolved beyond being a mere rule of evidence. It also encompasses estoppel by deed and estoppel in res judicata. However, there has been an ongoing debate regarding whether estoppel is a rule of evidence or substantive law.

General Conditions of Estoppel

  • Reciprocity: Estoppel must bind both parties involved in the litigation.
  • Cannot Circumvent the Law: Estoppel cannot be used to evade legal requirements or contractual obligations.
  • Certainty: Estoppel requires clear and unambiguous representation.
  • Conflicting Estoppels: When conflicting estoppels arise, they cancel each other out.
  • Fulfilling Doctrine of Estoppel: Estoppel is an equitable doctrine, and one seeking its application must also act equitably.

Estoppel Does Not Create a Cause of Action or Title

Estoppel operates as a bar to a lawsuit but does not extinguish the underlying right. It deals with facts, not rights. While it can affect or create substantive rights between parties, third parties remain unaffected.

When Estoppel Does Not Apply

Estoppel is not applicable in criminal cases and cannot be invoked against unlawful compromises. It should also be specifically pleaded in a legal proceeding; failure to do so may result in its inadmissibility.

In conclusion, estoppel is a vital concept in legal proceedings, limiting the introduction of certain evidence based on representations made by one party to another. Understanding its various forms, scope, and conditions is essential for both legal practitioners and individuals navigating the legal system.
