The groups said the rules remove mandatory public notification and hearings before developments are approved, while making consultations with technical agencies and stakeholders optional.

“This goes against the spirit of the Federal Territories Planning Act, disregards SDGs 10, 11 and 17 on inclusivity, public participation and partnerships, and erodes community rights that have existed for over five decades,” they said in a joint statement.

Speaking for the groups, Kuala Lumpur Residents Action for Sustainable Development Association (KLRA+SD) said public participation is vital to protect communities from risks such as landslides, floods, traffic congestion and environmental degradation.

Without mandatory engagement, it warned, key reports such as environmental, traffic and social impact assessments may never be shared with the public.

“Unchecked mayoral discretion removes accountability and centralises decision-making, making the planning process vulnerable to inconsistency, political pressure, and loss of public trust,” it said.

The objections come despite Kuala Lumpur City Hall (DBKL) insisting that stakeholder consultation will remain under the new rules.

DBKL said Rule 3 of the new regulations mandates consultations, but such consultation is only required for certain projects, including high-density or temporary developments, before they can be approved.

Seputeh MP Teresa Kok previously raised concerns about the regulations, saying they have given the Kuala Lumpur mayor excessive powers to approve developments in the city.

KLRA+SD urged DBKL to delay enforcing the new rules until thorough public consultation is held, and to publish the list of developments still being processed under the revoked 1970 rules.

It also called for restoration of the requirement to consult technical agencies, affected communities and stakeholders before approving projects.
