Definition of a contract: contract is an agreement enforceable at law, made between two or more persons, parties are legally bound to perform promises contained in the contract
Offer: expression of willingness to contract on certain terms made with intention to be legally binding as soon as it is accepted by whom it is addressed
Objective test: 1. whether conduct of alleged offeror is such as to induce a "reasonable person" to believe they are making an offer (Leonard v PepsiCo)
2. whether alleged offeree actually holds that belief, whether they believe the offeror is making a genuine offer (Keller v Holdman)
Buhrer v Tweedie: No offer for T to accept as the condition of the final approval from solicitors did not get fulfilled, therefore no acceptance and no contract was concluded
