Under Australian law, it is necessary for an acceptance to be made based on the offer or continuation of an offer.  Under the Single Code of Commerce (UCC) para. 2-207(1), a clear expression of acceptance or written confirmation of an informal agreement may constitute valid acceptance, even if it contains conditions that complement or nullify the offer or informal agreement on the offer or informal agreement. Additional or derogatory conditions are considered to be proposals to complete the contract in accordance with the UCC, p. 2 to 207 (2). Between traders, such conditions become an integral part of the contract, unless acceptance is the essential requirement that the parties have, subjectively, conduct that demonstrates their consent. After this session of the theory of the spirit of the treaty, a party was able to resist a claim of violation by demonstrating that it did not intend to be bound by the agreement, only if it seemed subjective that it intended to do so. This is not satisfactory because one party does not have the opportunity to know the undisclosed intentions of another party. One party can only act on the basis of what the other party objectively reveals (Lucy V Zehmer, 196 Va 493 84 S.E.
2d 516) to be its intention. Therefore, a real meeting of minds is not necessary. In fact, it has been argued that the idea of “meeting minds” is a very modern mistake: the judges of the 19th century spoke of the “ad idem consensus” that modern teachers wrongly translated into “meeting spirits”, but which in fact means “agreement with the same cause”.  “Agreement between experimental observations and theory” 3. Korbetis v Transgrain Shipping – Notification of acceptance must be made within a reasonable time, otherwise the offer expires to Bryne v Van Tienhoven – the offer of 1 October had not been withdrawn at the time of its adoption and the contract was therefore concluded when it was adopted on 11 October – despite the absence of an agreement between the parties. The bidder retracted on October 8, but Offeree did not receive it until October 20, 2008 an indeterminate item such as “quantities you can order” or “how and if necessary” so acceptance of this offer does not result in a binding contract on that date. Offer and acceptance are the agreement and the intention to create legal relationships and to define whether this is a legally binding contract in court. If one of these elements is missing, a valid contract cannot occur. o the courts may decide that there is no valid agreement and stop the performance of the contract, they are hesitant to do so once the benefit has begun – British Steel Corporation v Cleveland Bridge and Engineering Some offers can only be accepted by the provision or non-compliance with a particular law. Once formed, these types of agreements are referred to as unilateral contracts and will be discussed in more detail in this article.
Other offers can only be accepted by a promise of return from the bidder. After their creation, these agreements will be called bilateral treaties and will be discussed in more detail in this article. o This is the rule of reflection: acceptance must reflect the terms of the offer. The problem lies in the fact that sometimes the bidder does not accept, but makes a counter-offer. This is a traditional approach 1.It must be an absolute and total acceptance of all the terms of the offer: p.7 (1). If there is a difference, even on an insignificant point, between the terms of acceptance, there is no contract. Supply and acceptance analysis is a traditional approach to contract law.
