Sladic & Anor v ACT Planning and Land Authority; Charter Hall Retail Reit & Ors v ACT Planning and Land Authority

The proceedings were brought by the Sladic family and Charter Hall Retail Reit in the ACT Civil and Administrative Tribunal. The applicants sought review of a decision by the ACT Planning and Land Authority to approve a development application for a shopping centre at Mitchell, ACT. The applicants argued that the decision was unreasonable and failed to consider relevant environmental factors and statutory obligations under the Environmental Protection Act 1997 (ACT). The respondents defended the decision, asserting that it was based on proper consideration of the evidence and was in accordance with the law.

The central legal issue before the Tribunal was whether the ACT Planning and Land Authority's decision to approve the development application was unreasonable, particularly in light of the applicants' contentions that the decision failed to adequately consider environmental impacts and statutory obligations. The Tribunal needed to determine if the Authority had properly exercised its discretion and if there were any errors in the decision-making process that rendered it unreasonable.

The Tribunal found that the decision was indeed unreasonable. It was determined that the Authority had failed to adequately address the environmental concerns raised by the applicants, particularly regarding the impact on the nearby Namadgi National Park. Furthermore, the Tribunal found that the Authority had not properly considered its statutory obligations under the Environmental Protection Act 1997 (ACT). The Tribunal concluded that the decision was made without proper regard to relevant environmental factors and statutory requirements, leading to the conclusion that it was unreasonable. Consequently, the Tribunal set aside the original decision and substituted it with a decision to refuse to approve the development application.
