Technical planning decisions by statutory authorities warrant judicial restraint absent patent illegality or manifest arbitrariness.

The Petitioners (a Residents Welfare Association and an adjoining school) challenged a building sanction plan dated 13.05.2024 granted by the MCD to M/s R.R. Texknit LLP (the Developer) for a high-rise Group Housing Society in Sector-B, Pocket-1, Vasant Kunj

The Petitioners alleged that the land was originally Gram Sabha land vested in the DDA and earmarked for low-rise development or green space per the 1987 Vasant Kunj Scheme

Conversely, the Respondents asserted the land is a private, unacquired parcel, supported by a 1974 Bhumidhari decree and 1996 denotification

The School specifically raised concerns regarding student safety and traffic congestion on the sole 13.5-meter internal access road

Procedurally, the Petitioners also sought to amend their petition to challenge the 1974 title decree

1. Whether the Petitioner RWA and the Petitioner School possess the requisite locus standi to maintain the writ petitions?

2. Whether the Petitioners' application for amendment (CM APPL. 10311/2025) to challenge the 1974 title decree should be allowed?

3. Whether the approvals and sanctions are contrary to MPD-2021, Unified Building Bye-Laws (UBBL) 2016, and the 2018 Private Land Regulations, particularly regarding road width (18m ROW) and height restrictions?

Regulations for Enabling the Planned Development of Privately Owned Lands, 2018," which allow integration of private pockets into existing layouts

Order VI Rule 17 of the CPC and the "due diligence" test from Vidyabai v. Padmalatha, holding that stale claims and changes to the nature of the suit are impermissible

Clause 4.4.3(B)(ii) of the Master Plan for Delhi (MPD) 2021 regarding the 18m Right of Way (ROW) for group housing in the context of "integrated layouts"

Principle of judicial restraint in technical planning matters established in Greater Kailash Part II Welfare Association v. DLF Universal Ltd., which mandates deference to expert statutory bodies unless there is patent illegality

The Court first upheld the Petitioners' locus standi, noting that neighbors directly affected by environmental and infrastructure changes have a right to be heard

it rejected the amendment application, ruling that challenging a 50-year-old title decree involves disputed questions of fact and title that cannot be adjudicated under Article 226, especially after gross delay

On the merits, the Court found that the project satisfied the 18m ROW requirement because the "integrated layout" of the entire pocket is serviced by arterial roads (24m–75m), and internal plots need not be viewed in isolation

The Court held that "conformity with surrounding development" under Clause 5.5 of the 2018 Regulations does not require exact replication of height, as MPD-2021 encourages vertical growth and density

environmental concerns regarding the "Morphological Ridge" were already balanced by the Supreme Court’s 2025 order, which permitted construction subject to strict CEC safeguards

The sanctions are valid, provided the Developer strictly adheres to all conditions imposed by the CEC, MoEFCC, and the Supreme Court regarding environmental safeguards and infrastructure. The Respondent authorities were directed to ensure strict compliance with sanctioned plans and safety norms during execution.
