Exceptions To The Entire Or Strict Performance Rule – Substantial Performance; Voluntary Acceptance Of Partial Performance; Divisible Contracts; Prevention Of Performance; Tender Of Performance; Time Of Performance; Vicarious Performance

Introduction

General Rule

• The entire or strict performance rule provides that:
  • A party must completely perform contractual obligations before becoming entitled to payment.
  • Incomplete performance generally prevents recovery.
• Leading authority:
  • Cutter v Powell (1795)
• However:
  • Strict application often produced harsh and unjust results.
  • Courts gradually developed exceptions.
  • These exceptions reduce the severity of the entire performance rule.

Purpose Of The Exceptions

Fairness

• Prevent injustice.
• Avoid disproportionate consequences.

Commercial Practicality

• Reflect commercial realities.
• Recognise that perfect performance is not always possible.

Prevention Of Unjust Enrichment

• Stop one party receiving substantial benefits without paying.

Balance

• Balance certainty against fairness.
