Trentelman v The Owners - Strata Plan No 76700

The High Court of Australia considered an appeal by Mr Trentelman against the Owners – Strata Plan No 76700 concerning the interpretation of by-laws governing the use of common property within a strata scheme. The dispute centred on whether Mr Trentelman’s use of a balcony attached to his lot, which was designated as common property, constituted a breach of the strata scheme’s by-laws.

The primary legal issue before the High Court was whether the balcony, despite being attached to Mr Trentelman’s lot, was in fact part of the common property of the strata scheme, and if so, whether his use of it was permissible under the relevant by-laws. This involved an examination of the strata plan, the definition of "lot" and "common property" under the relevant strata legislation, and the construction of the by-laws themselves.

The Court reasoned that the strata plan clearly delineated the boundaries of the lots and the common property. It found that the balcony, as depicted on the strata plan, was not included within the boundaries of Mr Trentelman’s lot and was therefore common property. The Court then considered the by-laws, which prohibited the use of common property without the consent of the owners corporation. As Mr Trentelman had not obtained such consent for his use of the balcony, his actions were found to be in breach of the by-laws. The Court affirmed the principles that the strata plan is determinative of what constitutes a lot and common property, and that by-laws must be adhered to by lot owners.
