Implied Terms In Corporate Agreements
1. Concept of Implied Terms
Implied terms are provisions that are not expressly written in a contract but are introduced by courts or statutes to:
- Give effect to the parties’ intentions,
- Make the contract workable, or
- Ensure fairness and reasonableness in corporate relationships.
Implied terms cannot contradict express terms, and they arise from three main sources:
- Statutory implication – imposed by law.
- Custom or usage – implied due to trade or industry practices.
- Common law (business efficacy or necessity) – to make the contract work or to reflect presumed intentions.
2. Categories of Implied Terms in Corporate Agreements
A. Terms Implied by Fact
- Necessary for the contract to operate effectively.
- Example: obligation for a managing director to act in good faith to achieve corporate objectives.
B. Terms Implied by Law
- Imposed automatically in certain relationships, e.g.:
- Directors’ duties under the Companies Act 2006
- Shareholder agreements (minority protection provisions)
C. Terms Implied by Custom or Practice
- Based on recognized trade or industry norms.
D. Terms Implied to Ensure Fair Dealing
- Courts may imply terms of good faith, loyalty, or mutual cooperation in joint ventures and shareholder agreements.
3. Tests for Implied Terms (UK Common Law)
Courts often use the following tests:
- Business Efficacy Test (The Moorcock [1889])
- Term is implied if necessary to make the contract workable.
- Officious Bystander Test (Shirlaw v Southern Foundries [1939])
- Term is so obvious that “if an officious bystander suggested it, both parties would agree.”
- Reasonableness / Fairness Test
- Common in shareholder agreements where one party cannot act oppressively.
