Event Register

Can an essential term be implied to complete an incomplete contract?

Lunchtime Series  04 November, 2019

Emeritus Professor John Carter and Elisabeth Peden SC

Dixson Room, Mitchell Wing, NSW State Library

12:30PM to 02:00PM

A simple fact situation confronted the Supreme Court of the United Kingdom in Devani v Wells [2019] UKSC 4. However, the court had to deal with an important question of principle. If a contract is incomplete because it omits an essential term, can the court fill the gap by way of implied term? The court said the answer is ‘yes’, disagreeing with the Privy Council in Scancarriers A/S v Aotearoa International Ltd [1985] 2 Lloyd’s Rep 419 at 422, a case accepted in Australia.
Other relevant aspects of Devani v Wells discussed in the seminar are:

  • the distinction between terms implied in fact and terms implied in law
  • whether an offer to contract can be inferred from silence
  • whether an estate agent's right to commission is determined under a default rule
