Formation of Contract under the Sale of Goods (United Nations Convention) Act 1995: Key Provisions and Their Purpose
The formation of a contract is a fundamental stage in commercial transactions governed by the Sale of Goods (United Nations Convention) Act 1995. Part II of the Convention meticulously outlines the legal framework that governs how contracts are formed, focusing on the nature of offers, acceptance, revocation, counter-offers, timing, and the moment a contract is concluded. These provisions exist to provide clarity and certainty in international sales contracts, ensuring parties understand when they are legally bound and under what conditions.
"A proposal for concluding a contract addressed to one or more specific persons constitutes an offer if it is sufficiently definite and indicates the intention of the offeror to be bound in case of acceptance." — Article 14(1)
Verify source in source document →
This provision defines what constitutes an offer, a critical element in contract formation. It ensures that an offer must be clear and demonstrate the offeror’s intention to be legally bound upon acceptance. This prevents ambiguity and protects parties from unintended obligations.
"An offer becomes effective when it reaches the offeree." — Article 15(1)
Verify source in source document →
The rule that an offer is only effective upon reaching the offeree establishes the moment from which the offeree can consider acceptance. This provision exists to prevent premature assumptions of contract formation and to allocate risk regarding communication delays.
"An offer, even if it is irrevocable, may be withdrawn if the withdrawal reaches the offeree before or at the same time as the offer." — Article 15(2)
Verify source in source document →
This clause balances the interests of both parties by allowing withdrawal of an offer before it is effectively received, even if the offeror initially indicated irrevocability. It protects offerors from being indefinitely bound by their proposals in uncertain circumstances.
"Until a contract is concluded an offer may be revoked if the revocation reaches the offeree before he has dispatched an acceptance." — Article 16(1)
Verify source in source document →
This provision clarifies that revocation is possible before acceptance is communicated, reinforcing the principle that a contract is not formed until acceptance is effective. It prevents premature contract formation and allows offerors to reconsider their offers.
"An offer cannot be revoked: (a) if it indicates... that it is irrevocable; or (b) if it was reasonable for the offeree to rely on the offer as being irrevocable and the offeree has acted in reliance on the offer." — Article 16(2)

This exception protects the offeree’s reasonable expectations and reliance interests, preventing unfair withdrawal of offers that the offeree has acted upon. It promotes good faith and fairness in commercial dealings.
"An offer, even if it is irrevocable, is terminated when a rejection reaches the offeror." — Article 17
Verify source in source document →
This provision ensures that a rejection unequivocally terminates the offer, providing certainty to both parties regarding the status of negotiations and preventing confusion over outstanding offers.
"A statement made by or other conduct of the offeree indicating assent to an offer is an acceptance." — Article 18(1)
Verify source in source document →
Acceptance is defined broadly to include any indication of assent, whether verbal or by conduct. This flexibility reflects commercial realities where acceptance may not always be formally expressed but is nonetheless binding.
"An acceptance of an offer becomes effective at the moment the indication of assent reaches the offeror." — Article 18(2)
Verify source in source document →
This provision fixes the exact moment a contract is formed, which is when acceptance reaches the offeror. It is essential for determining rights and obligations, especially in cross-border transactions where communication delays are common.
"A reply to an offer which purports to be an acceptance but contains additions, limitations or other modifications is a rejection of the offer and constitutes a counter-offer." — Article 19(1)
Verify source in source document →
This rule prevents the "battle of forms" problem by treating any modified acceptance as a counter-offer, thereby requiring fresh acceptance. It ensures clarity about the terms on which parties agree.
"A period of time for acceptance fixed by the offeror in a telegram or a letter begins to run from the moment the telegram is handed in for dispatch or from the date shown on the letter..." — Article 20(1)
Verify source in source document →
This provision addresses the timing of acceptance periods in written communications, providing certainty about when the acceptance window starts. It is particularly relevant in international trade where postal delays may occur.
"A late acceptance is nevertheless effective as an acceptance if without delay the offeror orally so informs the offeree or dispatches a notice to that effect." — Article 21(1)
Verify source in source document →
This clause allows for flexibility by permitting late acceptance to be effective if the offeror promptly waives the delay. It encourages commercial pragmatism and prevents unnecessary disputes over timing.
"A contract is concluded at the moment when an acceptance of an offer becomes effective in accordance with the provisions of this Convention." — Article 23
Verify source in source document →
This final provision confirms the precise moment of contract conclusion, providing legal certainty and predictability in international sales transactions.
Definitions Under Part II: Clarifying Contract Formation Terminology
Part II also provides essential definitions to ensure consistent interpretation of terms related to contract formation. These definitions exist to eliminate ambiguity and facilitate smooth commercial interactions.
"A proposal for concluding a contract addressed to one or more specific persons constitutes an offer if it is sufficiently definite and indicates the intention of the offeror to be bound in case of acceptance." — Article 14(1)
Verify source in source document →
Reiterating the definition of an offer, this provision ensures that only clear and intentional proposals qualify as offers, preventing misunderstandings.
"A statement made by or other conduct of the offeree indicating assent to an offer is an acceptance." — Article 18(1)
Verify source in source document →
This broad definition of acceptance accommodates various forms of assent, reflecting commercial realities.
"A reply to an offer which purports to be an acceptance but contains additions, limitations or other modifications is a rejection of the offer and constitutes a counter-offer." — Article 19(1)
Verify source in source document →
Defining counter-offers prevents confusion by treating modified acceptances as rejections and new offers.
"For the purposes of this Part of the Convention, an offer, declaration of acceptance or any other indication of intention 'reaches' the addressee when it is made orally to him or delivered by any other means to him personally, to his place of business or mailing address or, if he does not have a place of business or mailing address, to his habitual residence." — Article 24
Verify source in source document →
This definition of "reaches" clarifies when communications are deemed effective, which is critical for determining timing of offers, acceptances, and revocations. It ensures fairness by specifying acceptable methods and locations for delivery.
Absence of Penalties and Cross-References in Part II
Notably, Part II of the Convention does not specify any penalties for non-compliance with its provisions. This absence reflects the Convention’s focus on establishing substantive rules for contract formation rather than prescribing sanctions. Enforcement and remedies for breaches are typically governed by other parts of the Convention or applicable national laws.
Similarly, Part II contains no cross-references to other Acts. This self-contained approach ensures that the rules on contract formation under the Convention are clear and directly applicable without reliance on external statutes, promoting uniformity in international sales law.
Conclusion
The provisions in Part II of the Sale of Goods (United Nations Convention) Act 1995 provide a comprehensive and precise legal framework for the formation of contracts in international sales. By defining key concepts such as offer, acceptance, revocation, and counter-offers, and by establishing clear rules on timing and effectiveness of communications, the Convention facilitates certainty and fairness in cross-border commercial transactions. The absence of penalties and cross-references underscores the Convention’s role as a substantive guide rather than an enforcement mechanism, leaving remedies to other legal instruments.
