Lesson 15: Principles of Interpretation

In contract law, the interpretation of a contract is crucial to determine the obligations and rights of the parties involved. This lesson delves into the principles of interpretation that courts use to decipher contracts.

1. Objective Theory of Contracts

The objective theory of contracts is the cornerstone of contract interpretation. Under this theory, a contract is interpreted based on the understanding of a reasonable person in the position of the parties at the time the contract was made. The subjective intentions of the parties are generally irrelevant.

Note: The objective theory contrasts with subjective theories, which focus on the actual intent of the parties.

2. Plain Meaning Rule

This rule dictates that if the language of the contract is clear and unambiguous, the courts will interpret the contract based on its plain meaning. This rule aims to honor the intent of the parties as expressed in the written contract.

3. Context and Circumstances

While the plain meaning rule is a starting point, courts often consider the context and circumstances surrounding the contract. This includes:

  • The purpose of the contract
  • The situation of the parties
  • Customs and practices in the industry

These factors help to understand the contract's terms in the context in which they were agreed upon.

4. Parol Evidence Rule

The parol evidence rule restricts the use of extrinsic evidence to interpret or add to the terms of a written contract. If a contract is intended to be a complete and final expression of the parties' agreement, evidence of prior or contemporaneous negotiations is generally inadmissible.

5. Ambiguities

When a contract term is ambiguous, courts strive to determine the parties' intent. Ambiguity occurs when a term is reasonably susceptible to more than one interpretation. Courts use several methods to resolve ambiguities, including:

  • Examining the entire contract to give effect to all parts
  • Considering the specific context in which the ambiguous term is used
  • Applying rules of construction, such as interpreting against the drafter

6. Rules of Construction

Rules of construction are guidelines that help courts interpret contract terms. Some of the commonly used rules include:

  • Ejusdem Generis: When general words follow specific words, the general words are interpreted to include only items of the same type as the specific words.
  • Expressio Unius Est Exclusio Alterius: The expression of one thing implies the exclusion of another.
  • Contra Proferentem: Ambiguous terms are interpreted against the party that drafted the contract.

7. Integration and Completeness

Courts determine whether a contract is integrated and complete. An integrated contract is a final and complete expression of the parties' agreement. If a contract is fully integrated, no external evidence can change or add to its terms.

Partial integration allows for external evidence to clarify ambiguous terms or fill in gaps, but not to contradict the written terms.

8. Trade Usage, Course of Dealing, and Course of Performance

Courts often look at trade usage, course of dealing, and course of performance to interpret the terms of a contract:

  • Trade Usage: Practices or methods of dealing that are regularly observed and followed in a place, vocation, or trade.
  • Course of Dealing: A sequence of conduct concerning previous transactions between the parties to a particular transaction that is fairly to be regarded as establishing a common basis of understanding for interpreting their expressions and other conduct.
  • Course of Performance: The conduct of the parties in performing the contract at issue, which can be used to interpret the contract terms.

9. Good Faith and Fair Dealing

The principle of good faith and fair dealing is implicit in every contract and requires that the parties act honestly and fairly towards each other. This principle ensures that neither party will do anything to undermine the benefits that the other party expects from the contract.

Note: Good faith and fair dealing are essential elements in enforcing the terms of a contract.

10. Implied Terms

In addition to the express terms, contracts may include implied terms that are not explicitly stated but are necessary to give effect to the intentions of the parties. Implied terms can arise from:

  • The nature of the agreement
  • The relationship between the parties
  • Legal requirements

11. Equitable Principles

Courts may apply equitable principles to interpret contracts, especially in cases where strict legal interpretation would lead to an unjust outcome. Some key equitable principles include:

  • Unjust Enrichment: Preventing one party from being unjustly enriched at the expense of the other.
  • Estoppel: Preventing a party from asserting something contrary to what is implied by a previous action or statement of that party.
  • Reformation: Modifying the written terms of a contract to reflect the true intentions of the parties.

12. Interpretation Against Public Policy

Contracts that violate public policy are unenforceable. Courts will interpret contract terms to avoid outcomes that would contravene public policy. Examples include:

  • Contracts that promote illegal activities
  • Contracts that restrain trade unreasonably
  • Contracts that are unconscionable

13. Review and Analysis

In summary, the principles of contract interpretation are varied and complex. Courts aim to honor the intent of the parties while ensuring fairness and justice. Key principles include:

  • Objective Theory of Contracts
  • Plain Meaning Rule
  • Context and Circumstances
  • Parol Evidence Rule
  • Ambiguities
  • Rules of Construction
  • Integration and Completeness
  • Trade Usage, Course of Dealing, and Course of Performance
  • Good Faith and Fair Dealing
  • Implied Terms
  • Equitable Principles
  • Interpretation Against Public Policy

Understanding these principles is crucial for anyone involved in drafting, reviewing, or enforcing contracts.
