RTS Flexible Systems v Molkerei Alois Müller [2010]

RTS Flexible Systems Limited v Molkerei Alois Müller GmbH [2010] UKSC 14 is a crucial case in English contract law, regarding the determination of whether an agreement has been reached between parties. The case revolved around whether a binding contract existed between Molkerei Alois Müller GmbH (Molkerei) and RTS Flexible Systems Limited (RTS) for the supply and installation of machinery, despite the absence of a finalised written contract.

Molkerei was purchasing automated packaging machinery from RTS. They initially created a letter of intent outlining the contract's entire price, with the expectation that the final contract terms would be based on the MF/1 terms. Despite producing a draft final contract, which stated it would only be effective upon execution and exchange, work commenced. Subsequently, terms were altered, leading to a dispute about the applicable contract terms.

The court held that the presence of a binding contract was established by evaluating the objective actions and communications between the parties rather than solely focusing on their subjective intentions. It took into account whether the parties had objectively intended to create legal relations and whether they had agreed upon all the essential terms required by law for the formation of a legally binding relationship.

Beginning work without a clearly defined and agreed-upon basis for payment can lead to disputes. The court emphasised the importance of having a precise understanding of the terms, especially regarding payment, before commencing work.

The court considered the performance of obligations and the execution of tasks as relevant factors in determining whether a contract had been formed. However, the actual performance alone doesn't always imply the existence of a contract; it is one of several factors to consider in the broader context.

The case highlights that just because negotiations are labeled as subject to contract does not necessarily mean that those terms will be binding. The court should not automatically assume that a contract exists based on these preliminary terms, as it ultimately depends on the circumstances.

In cases where standard terms are typically used (as in contracts for the supply of goods), disagreements over which standard terms apply can complicate the determination of a binding agreement. It is important that parties should be clear about which terms are to govern the contract.

Overall, the case underscores the complexity of ascertaining whether a binding contract exists in situations where parties engage in negotiations, commence work, but have not finalised all terms in a formal written agreement. The court's decision heavily weighs the objective actions and communications of the parties and emphasises that each case is assessed based on its unique circumstances.
