The Applicant further cited the decision of the Court of Appeal in Perbadanan Pengurusan Trellises & Ors v Datuk Bandar Kuala Lumpur & Ors [2021] 2 CLJ 808, which was affirmed by the Federal Court in Datuk Bandar Kuala Lumpur v Perbadanan Pengurusan Trellises & Ors and Other [2023] 5 CLJ 167, where the Court of Appeal allowed the applicant’s application for judicial review for the reason, among others, that: “[108] In any event, given our views earlier that there is a common law duty to inform the adjoining landowners of a hearing and of their right to attend and express their concerns at the hearing, it makes sense that there is a corresponding duty on the Commissioner, that is, the Datuk Bandar, to inform those who attended of the decision made, the outcome of the hearing and the response to their objections and/or concerns. The presence of r. 5(8) amplifies this requirement especially in relation to the applicant for planning permission and to those who objected. Since these other appellants were not informed of the decision, there is clearly procedural impropriety in the decision reached which renders the development order granted, liable to be quashed.”.
