Section 28 enables the Authority to issue stop‑work orders where development is being carried out without permission, contrary to plan, or in breach of conditions. Typically the Vice‑Chairman issues a notice directing immediate stoppage of development activities and warning of further action, including demolition and prosecution, in case of non‑compliance. This provision allows swift intervention at an early stage, often before the structure is completed, which is vital given the difficulty of reversing completed high‑value construction in dense urban areas.[7][15][10][3]

Judicial decisions have treated Section 28 as a preventive measure, distinct from punitive demolition under Section 27, but subject to similar requirements of fair notice and an opportunity to respond, especially where stoppage has severe economic impact. In writ petitions challenging stop‑work notices, High Courts have generally declined to interfere at the threshold where the Authority can show prima facie violation of the Act or the plan, but have set aside orders where they were arbitrary or issued without jurisdiction.[15][7]
