Sinclair and Sinclair v Siljak (Civil Dispute)

In the case of Sinclair and Sinclair v Siljak, the applicants, Cassandra Sinclair and Alistair Sinclair, sought damages from the respondent, Anthony Siljak, for damage caused by the collapse of a retaining wall on the respondent’s property into the applicants’ property. The respondents counterclaimed for expenses related to the retaining wall and fence, as well as loss of wages. The dispute was heard and determined by the ACT Civil and Administrative Tribunal.

The primary legal issues were whether the respondent owed the applicants a duty of care in the construction of the retaining wall on his property, whether that duty was breached, and if so, what damages were owed. The court had to consider the standard of care expected of a reasonable person in the construction of retaining walls, the impact of the location of the walls on the common boundary, and the evidence presented regarding the cause of the collapse.

The Tribunal found that the respondent had breached the duty of care owed to the applicants by failing to construct the retaining wall in accordance with the standard of a reasonable person. The collapse of the wall was directly attributable to the respondent’s failure to properly construct it. The court awarded the applicants $6,292.00 in damages for the repair of the retaining wall, plus additional costs. The counterclaim by the respondent was dismissed as there was no evidence of negligence on the part of the applicants.

The final orders of the Tribunal required the respondent to pay the applicants $5,637.00 by a specified date, representing the difference between the awarded damages and the dismissed counterclaim. The Tribunal’s decision was based on the evidence presented and the applicable legal standards for duty of care and negligence in the construction of retaining walls on common boundaries.
