They cited Perbadanan Pengurusan Sunrise Garden Kondominium v.Sunwasy City (Penang) Sdn Bhd & Ors [2023] 2 MLJ 621 (Sunrise Garden) wherein Nallini Pathmanathan FCJ held at 654 – “For the purposes of the present appeal, s 22(2A)(c) is of particular relevance. In its consideration of an application for planning permission, the State Planning Committee is under a duty to request for advice from the NPPC where the application involves ‘development affecting hill tops or hill slopes, in an area designated as environmentally sensitive in a development plan’. This amendment is highly significant in ensuring two fundamental aspects of the TCPA, that of integration between Federal and State and environmental protection. It is to be recalled, again, that one of the functions of the NPPC is to promote environmental protection and sustainable development. The TCPA’s focus on integration between Federal and State, environmental protection, and sustainable development is also clear from the explanatory statement to the bill and Hansard debates. Although statutory interpretation is exclusively within the province of the judiciary, Hansard and Parliamentary speeches may serve as an interpretive aid (Maple Amalgamated Sdn Bhd & Anor v Bank Pertanian Malaysia Bhd [2021] 6 MLJ 348; [2021] 8 CLJ 409 at para [53]). With respect to the inclusion of s 22(2A), development affecting hill tops or hill slopes are no longer merely an issue of local or state governance. It is also a federal level and national issue. The inclusion of the role of the Federal Government in town and country planning would promote coordination between the local authority, State-level authorities, and the Federal Government, thus ensuring development takes place in a well-balanced manner and accords with the sharing of responsibilities as well as the principle that the public interest precedes private interest in the use and development of land. This much was made evident by the Minister in the Hansard debates that took place on 30 July 2001 and 31 July 2001 (this argument was raised in the appellant’s submissions (encl 57), pp 140–143). It is worth summarising in brief the prominence of environmental protection in the TCPA following the passing of the Amendment Act. The fact that such amendments were introduced throughout the TCPA demonstrates the legislative intent in amending the TCPA so that the statute would play a more prominent and effective role in environmental protection. Firstly, the very creation of the NPPC and its functions including environmental protection and sustainable development. Secondly, and as highlighted earlier, the insertion of the NPPC’s role throughout the planning process and, given the NPPC’s functions, ensuring that environmental considerations are taken into account throughout. In the context of the above provisions, and the significant amendments made to the TCPA vide the creation of the NPPC, it is clear that the TCPA is aimed towards achieving integration between Federal and State as well as environmental protection. The NPPC can be seen as a buckle or link between these two objectives; as a body sitting at the top of the planning administration hierarchy, it is tasked with the responsibility of ensuring development throughout Peninsular Malaysia takes into account environmental protection and sustainable development.” Principles of law governing judicial review proceedings
