The IRAC technique, which stands for Issue, Rule, Application, Conclusion, is a commonly used strategy in legal analysis. Below is an example of how the IRAC approach may be used to analyse a contract law matter within the Australian jurisdiction:

Issue The essential question is whether a legally binding agreement has been established between Party A and Party B in the particular situation. Rule In Australian contract law, a contract is deemed legitimate when it satisfies the following elements: offer, acceptance, purpose to form legal relations, and consideration. Furthermore, the terms of the contract must possess a definite and unambiguous nature, while also adhering to all statutory and common law prerequisites.

Application Party A proposed selling a scarce and valuable collector item to Party B for a price of $1,000. Party B, in acknowledgment, consented to acquire the item at the designated price. There is an evident offer made by Party A and acceptance made by Party B. The presence of consideration (the payment of $1,000) in business agreements creates a presumption of the purpose to establish legal relations. Nevertheless, it is crucial to scrutinise the provisions of the contract to ensure both clarity and validity. If the provisions of the contract are found to be ambiguous or lacking in detail upon careful examination, it might potentially impact the fulfilment of the certainty requirement. In addition, if the subject matter of the contract is unlawful or against to public policy, it may cause the contract to be invalid. It is crucial to take into account any legal regulations that can affect the legality of the contract.

Conclusion Based on the above facts, it may be concluded that a legally binding contract has been established between Party A and Party B. This conclusion is drawn from the presence of an offer, acceptance, purpose to create legal obligations, and consideration. Nevertheless, a comprehensive examination of the terms and legal aspects of the contract is required to arrive at a conclusive decision. If the provisions of the contract are unambiguous and according to the law, it is quite probable that the contract is legitimate. Alternatively, other factors and legal concepts may be relevant, impacting the contract's legitimacy.
