Kingston v. Preston

2 Doug. 689, 99 Eng. Rep. 437 (K.B. 1773)

Court of King's Bench · 1773

Rule

Covenants in a contract are mutual and dependent where the performance of one is in the nature of a condition precedent to the performance of the other. Where dependent covenants exist, a party need not perform until the other has performed or tendered performance.

Facts

Kingston agreed to serve as Preston’s apprentice in the silk-mercer trade, after which Preston was to transfer his business to Kingston and Preston’s nephew as partners. Kingston was required to provide good security for the payments he would owe Preston for the business. Kingston completed the apprenticeship but failed to give the security. Preston refused to deliver the business. Kingston sued for breach.

Holding

Lord Mansfield held for Preston. The provision of security was a condition precedent to Preston’s obligation to deliver the business; Kingston’s failure to give security discharged Preston’s duty to perform.

Reasoning

Lord Mansfield articulated a now-classical taxonomy of covenants: (1) mutual and independent, where each party performs without regard to the other; (2) conditional and dependent, where one party’s performance depends on the other’s prior performance; and (3) mutual conditions to be performed at the same time. Where the obligations are of the dependent kind, the order is fixed by the bargain’s structure: a party need not perform until the condition has been satisfied. On the facts, security was the entire foundation of Preston’s willingness to part with the business; it was unmistakably a condition of his performance.

Why it matters

Kingston v. Preston is the foundational case for constructive conditions of exchange. The taxonomy Lord Mansfield supplied remains the structure modern courts use to determine order of performance, and it underwrites Restatement (Second) §§ 234–238. The case is the chapter’s anchor for understanding when a party’s duty arises and when it is discharged by the other’s failure to perform.

The trap

Assuming the deed told the parties their covenants were dependent. It did not. Mansfield read dependence into the deal from its structure. Students who think the case turns on express language miss the doctrinal move: courts can supply conditions where the bargain's structure presupposes them. R2d § 226 codifies the move; R2d §§ 234-237 carry the modern constructive-conditions-of-exchange framework.

The operational intuition the case is designed to break. Naming the trap is what the Socratic exchange is for.

Surfacing · 45 sec

Q. A silk-mercer apprentice (Kingston) and master (Preston) agree: Kingston will work for the master, then receive the business and stock and a 14-year partnership. Kingston is to give 'sufficient security' for the deferred payments. Kingston shows up for the handover without giving the security. Does the master have to convey?

Look for: The split. Some students say yes, both sides have promises, both sides must perform. Some students sense the master should not have to part with the business on Kingston's bare word. Surface both before the doctrine arrives.

Holding · 45 sec

Q. What did Lord Mansfield hold?

Look for: No. The master need not convey. Kingston's security obligation was a condition precedent to the master's duty.

Reasoning · 120 sec

Q. Before Kingston, English courts presumed promises were independent: each promise enforceable in its own action regardless of the other's performance. Mansfield changes that. By what authority? The deed did not use the word 'condition.'

Trap: Students assume the parties said the promises were dependent. They did not. Mansfield reads dependence into the structure. The trap is treating the case as straightforward textual interpretation when it is doctrinal innovation.

Board: R2d § 226: an event may be made a condition by the parties' agreement, including by interpretation.

Push back: Look at the deed. Does it use the word 'condition'? If not, where does Mansfield get the authority to make Kingston's security a condition precedent?

Push to: Mansfield reads dependence from 'the evident sense and meaning of the parties.' The structure of the deal (the master should not have to trust Kingston's personal credit) supplies the constructive condition. R2d § 226 codifies the move: courts can supply conditions from the parties' undertaking. R2d §§ 234-237 supply the modern constructive-conditions-of-exchange framework.

Hypothetical · 60 sec

Vary. Same facts, but the deed explicitly says: 'The covenants herein are independent.' Same result?

Point: Express language can override the constructive condition. Mansfield's default rule yields to explicit party choice. Tests whether students see that R2d § 226 covers both express and court-supplied conditions, with express choice controlling when present.

Integration · 60 sec

Q. Modern M&A contracts have closing-conditions sections running to dozens of pages. Why do sophisticated parties still spell them out when Mansfield gave them the constructive-condition default? And why did 18th-century commerce need this rule, what was wrong with the independent-covenant default for the kind of long-term deals that were emerging?

Land: The constructive condition is a default; explicit drafting is how parties tailor risk allocation. Kingston opens the door to the modern world of conditional commitments. Binyan av: Kingston is the paradigm case that the modern doctrine extends. The rise of bilateral executory contracts in commercial life made the independent-covenant default untenable.
