In an attempt to provide a pragmatic and commercial
judgment the High Court has explained what it means when a party
promises to "use reasonable endeavours" in performing a
We are all familiar with the reasonable or best endeavours
clause. It pops up in all kinds of contracts.
This time the clause was in a Gas Supply Agreement (GSA) between
Verve (the trading name of Electricity Generation Corp) and
Woodside Energy and other sellers (Woodside).
A Fire in the West
In 2008 a massive fire caused the shutdown of a major gas plant
in WA resulting in demand for gas exceeding supply. Woodside sought
to take advantage of their position and told Verve that they
couldn't deliver the supplemental quantities noted in the
"reasonable endeavours" clause contained in the GSA.
Instead, what they would do was provide those amounts under another

"reasonable endeavours" to supply the supplemental
amounts under the GSA.

"reasonable endeavours" doesn't mean that a
company has to do everything in its powers;
the nature of an obligation imposed depends on what is
reasonable in the circumstances and you don't have to act
against your own commercial interests;
contracts may include their own internal standard of
reasonableness, such as here where Woodside was expressly allowed

supplemental gas to Verve.
We think that the likely effect of this case is that everyone
will start drafting long definitions of what "reasonable
endeavours" means for each contract. Hardly likely to result
in short, plainly written contracts. Still, if you consider the
three points above and tailor the 'reasonableness' to suit
your company hopefully it will be interpreted in a way that makes
