Four words before the breach
- Nimbus buys 2,000 kg of flour a fortnight at 2.00 a kilogram. When the mill delivers twenty days late, recovery turns on offer, acceptance, consideration and intention.
- Jurisdiction: England and Wales, contract formed and broken here.
Formation: the four boxes
- Offer 要约: the mill's quote - an intention to be bound on specified terms. Acceptance 承诺: Nimbus's signed order, unqualified and communicated.
- Consideration 对价: 4,000 pounds moves for flour - existence counts, adequacy does not (Chappell v Nestle: the wrappers counted). Intention is presumed between businesses.
Which element does the argument turn on?
Route each scenario to the element it actually tests.
Contract: 2,000 kg at 2.00. The price, in pounds?

2,000 x 2.00 = 4,000.
Chappell v Nestle decided that:
难度 1/5 · 今日首次完成可获 100 金币及少量额外奖励
Existence counts, adequacy does not.
A reply that changes the delivery date is acceptance.
难度 1/5 · 今日首次完成可获 100 金币及少量额外奖励
It is a counter-offer; acceptance must be unqualified.
The breach arithmetic
- Cover purchase at 2.40: 4,800 - the 4,000 contract price = 800 price-difference loss.
- The festival date was in the contract, so the 2,100 lost weekend is within contemplation (Hadley v Baxendale). Expectation damages: 800 + 2,100 = 2,900.
Cover loss 800 plus festival loss 2,100. Expectation damages?
难度 2/5 · 今日首次完成可获 140 金币及少量额外奖励
800 + 2,100 = 2,900.
The 2,100 festival loss is recoverable because:
难度 1/5 · 今日首次完成可获 100 金币及少量额外奖励
Hadley v Baxendale: losses arising naturally or within contemplation.
The clause and the penalty test
- The late-delivery clause: 250 a day x 20 days = 5,000 - 2,100 more than the loss.
- Liquidated damages 预定违约金 survive; penalty clauses do not. The Cavendish test: does the sum protect a legitimate interest proportionately, or just deter?
The clause charges 250 a day for 20 days. Its face value?
难度 2/5 · 今日首次完成可获 140 金币及少量额外奖励
20 x 250 = 5,000 - 2,100 above the loss.
Match each remedy to its use.
难度 2/5 · 今日首次完成可获 140 金币及少量额外奖励
Money first; compulsion rare; punishment never.
A clause worth more than the loss is automatically a penalty.
难度 1/5 · 今日首次完成可获 100 金币及少量额外奖励
Cavendish: the test is legitimate interest proportionate to loss, not the gap alone.
Three contract slips
- Judging consideration by adequacy. A peppercorn can be consideration; nothing cannot.
- Claiming the clause and skipping the loss proof. The penalty test needs both legs.
- Letting one proceeding's defence contradict another's. Write every answer with all three in view.
Recap
- Offer + acceptance + consideration + intention = enforceable.
- Damages within contemplation: 800 + 2,100 = 2,900.
- Liquidated protects, penalty punishes: 250 a day lives or dies on its evidence.
