## What is this about?

A contract may be discharged by performance, agreement, breach, or operation of law (including frustration). Breach ranges from minor defects to repudiation entitling termination. This note maps the discharge routes; frustration and remedies have companion corpus entries.

## What is the core rule?

Discharge by performance requires substantial performance of entire obligations subject to entire-contract vs severable analysis and the de minimis principle. Discharge by agreement includes release, variation, and accord and satisfaction (consideration usually required unless deed). Repudiatory breach or renunciation entitles the innocent party to terminate and claim damages; breach of condition or a serious innominate-term breach (Hong Kong Fir) likewise. Affirmation elects to keep the contract alive. Frustration discharges both parties where a supervening event radically changes performance (see frustration note). Limitation and waiver issues often decide practical outcomes.

## What are the elements or test?

1. Has the contract been fully/substantially performed?
2. Any agreed variation, release, or rescission?
3. Is there renunciation, incapacitation, or actual breach?
4. Classify term: condition, warranty, or innominate — termination available?
5. Election: terminate or affirm? Communication of election?
6. Frustration or force majeure clause instead of breach analysis?

## Which authorities matter?

- **Hong Kong Fir Shipping Co Ltd v Kawasaki Kisen Kaisha Ltd [1962] 2 QB 26** — Innominate terms: termination depends on the gravity of consequences.
- **Photo Production Ltd v Securicor Transport Ltd [1980] AC 827** — House of Lords on termination, damages, and construction after serious breach.
- **White and Carter (Councils) Ltd v McGregor [1962] AC 413** — Innocent party may sometimes affirm and claim the contract price despite repudiation — limited by legitimate interest/cooperation constraints in later cases.
- **Davis Contractors Ltd v Fareham UDC [1956] AC 696** — Frustration threshold — radically different performance (see dedicated frustration note).

## How does this apply in practice?

Always read termination clauses and notice provisions in commercial contracts. UCTA/CRA may control exclusion of liability for breach. Pair with remedies-for-breach and frustration notes.

## What are common pitfalls?

- Treating every breach as repudiation
- Failing to communicate termination clearly and affirming by conduct
- Ignoring entire-obligation rules in staged construction/supply contracts
- Running frustration where the contract allocates the risk

## When would a practitioner use this?

Termination advice, repudiation letters, and dispute framing between breach and frustration.

## Quick reference

Discharge: performance, agreement, breach, frustration. Termination: repudiation/renunciation, condition, or serious innominate breach (Hong Kong Fir). Elect carefully. See frustration and remedies companions.
