Deguisa v Lynn

The Full Court of the Supreme Court of South Australia considered the enforceability and effect of restrictive covenants registered on Torrens title land in the matter of *Deguisa v Lynn*. The dispute concerned a covenant that prohibited the construction of any building other than a single private dwelling house on a particular parcel of land. The applicants sought to build a second dwelling on the land, which the respondents, owners of neighbouring properties, argued would breach the covenant.

The central legal issues before the Court were: (1) whether the restrictive covenant was enforceable against the applicants, and (2) if enforceable, what was the proper interpretation and scope of the covenant, particularly in relation to the proposed construction of a second dwelling. The Court was required to determine whether the covenant, as registered, effectively prevented the subdivision of the land and the erection of more than one dwelling.

The Court reasoned that the covenant, by its plain language, restricted the land to a single private dwelling house. It held that the covenant was not merely a personal one but ran with the land and was therefore enforceable against subsequent owners. The Court applied the general principles of statutory interpretation to the wording of the covenant, finding that the prohibition on building "any building other than a single private dwelling house" clearly encompassed the erection of a second dwelling, irrespective of whether it was intended to be a separate residence. The Court rejected arguments that the covenant should be interpreted in a manner that permitted subdivision or the erection of multiple dwellings, finding no ambiguity in its terms.

The Court dismissed the applicants' appeal, upholding the primary judge's finding that the restrictive covenant was valid and enforceable and that the proposed construction of a second dwelling would breach its terms.
