Prior to the High Court’s decision in Mann v Paterson Constructions Pty Ltd [2019] HCA 32, claims by builders and contractors on a quantum meruit basis could not exceed the agreed contractual price. That practice has now been ruled out in many cases. At an event hosted by the Society of Construction Law Australia (SoCLA) and Clayton Utz (Brisbane), Michael Trim and Sean Russell looked at the background decision, precisely what was and was not decided and how the reasoning can affect both inside and outside the construction industry.
The key areas reviewed included:
- the differences between divisible and entire obligations
- understanding what the case decided
- the three sets of differing reasoning
- variations regulated by statute
- broader impact
The micro-learning slides from the event can be found below.
