## Facts

- Hillas & Co Ltd and Arcos Ltd entered into a 1930 commercial agreement for the sale of 22,000 standards of softwood goods.
- The contract included an option clause (Clause 9), allowing Hillas & Co to purchase an additional 100,000 standards during the 1931 season at a 5% discount.
- On 22 December 1930, Hillas & Co exercised this option, but Arcos Ltd refused to supply, arguing lack of binding effect due to insufficient specification of "softwood goods of fair specification".
- Arcos Ltd claimed the option lacked certainty regarding the type, quality, and price of timber, making the contract unenforceable.
- Hillas & Co brought a claim for breach of contract, leading to scrutiny of the requirements for contract formation and the court’s approach when commercial terms are incomplete.

## Issues

1. Whether the option agreement in Clause 9 was sufficiently certain to be legally binding and enforceable.
2. Whether the term "softwood goods of fair specification" was too vague, rendering the option an unenforceable "agreement to agree".
3. Whether courts could imply terms into the contract based on commercial context and previous dealings to cure any uncertainty.

## Decision

- The House of Lords held in favour of Hillas & Co Ltd, finding the option agreement legally binding.
- The court ruled that the description "softwood goods of fair specification" could be interpreted and given reasonable meaning through implication of terms.
- The judges emphasised the court’s obligation to make commercial contracts effective where intention to be bound is clear, rather than invalidate them on technical grounds.
- Past dealings and trade practices between the parties were considered to supply any missing specifics regarding goods.
- The court distinguished the case from May & Butcher v R, where lack of price rendered a contract unenforceable, whereas here the absence of detailed specification was not fatal.

## Legal Principles

- Sufficient certainty is required for contract enforceability, but absolute precision is not always essential in commercial contexts.
- Courts may imply terms where intention to create legal relations exists and where trade practice or previous dealings provide an objective basis.
- Vague or incomplete terms, such as "fair specification," may be given effect if capable of reasonable interpretation by the court.
- Essential elements, such as price, may not be implied if completely absent; however, non-essential or contextual terms may.
- Commercial agreements should be interpreted fairly and broadly, with a view to upholding their validity where possible.

## Conclusion

Hillas & Co Ltd v Arcos Ltd confirms that courts will uphold commercial agreements by implying terms where necessary to give effect to the parties’ intentions, provided there is a clear intention to be bound and sufficient contextual or historical basis to fill any uncertainty, distinguishing between essential and non-essential contractual elements.
