LAW5002 Principles of Contract Law A is the Monash University Juris Doctor unit on how a binding contract is formed and what its terms mean — agreement, consideration, intention, certainty and capacity, then formalities, privity, estoppel, the construction and implication of terms, and the Australian Consumer Law overlay. This free study guide maps each doctrine to its leading case and drills the problem-question / IRAC method the 60% final exam rewards. It is an independent study companion, not affiliated with or endorsed by Monash University, and is not legal advice.

Existing duty and practical benefit — is the promise supported by consideration?
- +1Issue: is Devi's promise to pay the extra $1,500 supported by consideration, given Priya was already contractually bound to do the painting?
- +1Rule: performing an existing contractual duty owed to the same promisor is generally not consideration (Stilk v Myrick).
- +1Rule (exception): a promise may still be supported where the promisor obtains a practical benefit (or avoids a disbenefit), provided there is no duress (Williams v Roffey; Musumeci v Winadell).
- +1Application: Priya is only doing what she already promised, so on Stilk v Myrick she provides no fresh consideration.
- +1Application (counter): Devi obtains a practical benefit — the cafe repainted before the inspection, avoiding delay and disruption — which can amount to consideration if Priya applied no illegitimate pressure.
- +1Conclusion: the promise is likely supported by consideration via the practical benefit Devi gained, absent duress; advise Priya it is probably enforceable, though Devi may argue Stilk v Myrick.
Key terms
- Offer
- An expression of willingness to be bound on stated terms, requiring only acceptance to form a contract; assessed objectively.
- Invitation to treat
- An invitation to negotiate or to make offers (for example a priced display or advertisement), which is not itself an offer capable of acceptance.
- Acceptance
- Final and unqualified assent to the terms of an offer, made in response to it and communicated to the offeror; a variation is a counter-offer.
- Consideration
- The price for which a promise is bought — a benefit or detriment moving from the promisee, given as a bargain; it must be sufficient but need not be adequate.
- Practical benefit
- A benefit obtained (or disbenefit avoided) that can supply consideration for a promise to pay more for an existing duty, provided there is no duress (Williams v Roffey; Musumeci v Winadell).
- Intention to create legal relations
- The objective intention of the parties to be legally bound; commercial dealings raise a strong inference of intention, domestic and social ones do not.
- Certainty and completeness
- The requirement that all essential terms are settled and sufficiently clear; an agreement to agree is void unless a mechanism or standard can fix the term.
- Capacity
- A party's legal ability to contract; minors are bound only for necessaries (paying a reasonable price), and an intoxicated party may avoid a contract if the other party knew of the incapacity.
- Privity
- The rule that only a party to a contract can sue or be sued on it, so a third party generally cannot enforce a contract made for their benefit.
- Estoppel
- An equitable doctrine preventing a party from resiling from an assumption they induced where another has relied on it to their detriment and it would be unconscionable to depart (Waltons Stores v Maher).
- Incorporation
- How a term becomes part of a contract — by signing a document, by reasonable notice before or at contracting, or by a consistent course of dealing.
- Exclusion clause
- A term limiting or excluding liability, construed on its natural and ordinary meaning in context, with ambiguity read against the party relying on it (contra proferentem).
- Consumer guarantee (ACL)
- A non-excludable statutory guarantee (such as acceptable quality of goods or due care and skill in services) owed to a consumer under the Australian Consumer Law.
- Unfair contract term (ACL)
- A term in a standard-form consumer contract that causes a significant imbalance, is not reasonably necessary to protect the advantaged party, and would cause detriment — and is therefore void.
LAW5002 FAQ
Can AI help me study LAW5002?
Yes, as a study aid. Sia is an AI tutor that can explain any step of contract-law reasoning for LAW5002 Principles of Contract Law A — walking you through how to classify a statement as a term or a representation, how the practical-benefit principle works, or how the Australian Consumer Law guarantees apply — and it will quiz you on the tests and leading cases. It explains the method step by step so you can learn it; it will not sit your exam or write your assessments for you, and the final exam does not permit generative AI, so use Sia to build understanding before you walk in.
Where can I find past exam papers or practice for LAW5002?
Official past papers and the current exam format for LAW5002 are published on Monash's Moodle unit page and library exam collection — always confirm the current duration, mark split and permitted-materials rules there. For extra reps, this free guide includes exam-style problem and short-answer questions with full model answers worked by IRAC, and you can ask Sia to generate fresh hypotheticals and mark your structure step by step.
What can Sia do that a textbook can't?
A textbook states the law; Sia applies it with you. You can paste a problem scenario and Sia will help you spot the issues, name the right test and authority, and structure an IRAC answer step by step, then ask you follow-up questions until the method sticks — an interactive tutor rather than a static page. It is a study aid that explains the reasoning and marks your IRAC structure; it never sits your exam or writes your assignment for you, hands you a model answer, or guarantees a grade — you do the work, Sia shows you the method.
Is LAW5002 hard?
LAW5002 Principles of Contract Law A at Monash University is demanding because the marks are for applying doctrine to novel facts under time pressure, not for memorising cases — but it becomes manageable once you drill the problem-question / IRAC method and can state each test with its leading case. The 60% final exam is where most of the mark sits, so most students find that regular IRAC practice, rather than re-reading, is what lifts the grade.
Is the LAW5002 exam open or closed book?
The final is an electronic eExam of problem questions; the most recent past paper was open book with no generative AI permitted, but the exact rules can change between teaching periods, so confirm the current permitted-materials list on Moodle before you rely on any printed notes.
Is there a hurdle in LAW5002?
The published assessment for LAW5002 — 10% class participation, a 30% written assignment and a 60% final exam — does not state a separate must-pass hurdle for any single component; standard Monash JD grading applies. Confirm the current rules on Moodle, as assessment details can be updated.
How is LAW5002 assessed?
Assessment is 10% class participation across the teaching period, a 30% written assignment (a 2,250-word problem-scenario response using AGLC citations, covering the earlier weeks' topics), and a 60% final exam — an electronic eExam of compulsory problem questions answered by IRAC on all topics covered. Check Moodle for the current weights and dates.
How to study for the exam
Treat LAW5002 Principles of Contract Law A at Monash University as a method unit, not a memory unit: because the final is a problem-question eExam marked on application, spend most of your revision running IRAC over fresh hypotheticals rather than re-reading slides. Build a one-page test-and-case grid for each doctrine on the spine — formation, formalities and privity, estoppel, the terms of the contract, and the Australian Consumer Law — so you can state the test, name the authority and apply it under time pressure. Draft to the word limit for the written assignment and to roughly two minutes per mark for the exam, always arguing both sides and finishing each issue with a clear, tentative conclusion.
