Dillon v Gosford City Council

In *Dillon v Gosford City Council*, the High Court of Australia considered a dispute between the appellant, Dillon, and the respondent, Gosford City Council. The case concerned the Council's liability for damage caused to the appellant's property by a stormwater drain. The appellant alleged that the Council had been negligent in the construction and maintenance of the drain, which had led to flooding and damage.

The central legal issue before the High Court was whether the Council owed a duty of care to the appellant in relation to the construction and maintenance of the stormwater drain, and if so, whether that duty had been breached. The Court was required to determine the scope of the Council's statutory powers and the extent to which those powers, when exercised, could give rise to a common law duty of care.

The High Court held that the Council, in exercising its statutory powers to construct and maintain stormwater drainage systems, owed a duty of care to landowners whose properties were likely to be affected by the system. This duty extended to taking reasonable steps to ensure the system was properly designed, constructed, and maintained so as to avoid foreseeable harm. The Court found that the Council had failed to exercise reasonable care in the maintenance of the drain, leading to the damage suffered by the appellant. The appeal was therefore allowed.
