Detala Pty Ltd v Byron Shire Council

Detala Pty Ltd (the developer) sought judicial review of a decision by the Byron Shire Council (the Council) to declare that its development consent had lapsed. The dispute concerned whether the developer had commenced construction works within the five-year period stipulated by the consent and whether the developer had breached conditions precedent to the commencement of those works, specifically regarding tree clearing and the obtaining of a construction certificate. The matter was heard in the Court of Appeal of New South Wales.

The primary legal issues before the Court of Appeal were: (1) whether the development consent had lapsed due to a failure to commence construction works within five years of its grant; (2) whether the developer had breached a condition requiring it to obtain authority for tree clearing prior to commencing works; and (3) whether the developer had failed to obtain a construction certificate before commencing works, thereby breaching a condition of the consent. The Court also considered the meaning and effect of the condition relating to tree clearing and whether the Council was estopped from asserting the lapse of the consent.

The Court analysed the commencement of works in light of the specific conditions attached to the development consent. It determined that the condition requiring authority for tree clearing was a condition precedent to the commencement of construction works. The Court found that the developer had not obtained the necessary authority for tree clearing, nor had it obtained a construction certificate, before commencing works. Consequently, the Court concluded that the developer had not validly commenced construction works within the five-year period as required by the consent, and therefore the consent had lapsed. The Court rejected the argument of estoppel.

The Court of Appeal dismissed the developer's appeal and affirmed the orders of the primary judge.
