Expert planning decisions by specialized authorities merit judicial restraint absent patent illegality or manifest arbitrariness.

The Petitioners (an RWA and a neighboring School) challenged the building sanction plan dated 13.05.2024 granted by the MCD to M/s R.R. Texknit LLP for a high-rise Group Housing Society in Vasant Kunj

The Petitioners alleged that the subject land was originally Gram Sabha land vested in the DDA, while the Respondents asserted it was a private, unacquired parcel

Historically, a 1974 Revenue Assistant order declared the predecessors of the developer as owners; this title was upheld in various appellate proceedings

The Petitioners claimed the project violated road-width norms (18m ROW), height restrictions, and environmental protections as the land allegedly falls within the Morphological Ridge

Procedurally, the Petitioners also sought to amend their writ to challenge the 1974 title decree after a 50-year delay

Regulations for Enabling the Planned Development of Privately Owned Lands, 2018, which allow the integration of private enclaves into DDA layouts

MPD-2021 Clause 4.4.3(B)(ii) regarding road width and Clause 5.5 concerning conformity with surrounding developments

Order VI Rule 17 of the CPC and the principle from Life Insurance Corporation of India v. Sanjeev Builders Pvt. Ltd., which prohibits amendments that fundamentally alter the case or address stale claims

Central Empowered Committee (CEC) framework and the "balance" principle established in Greater Kailash Part II Welfare Association v. DLF Universal Ltd., which restricts judicial interference in expert technical planning decisions

The Court rejected the amendment application, ruling that a 50-year delay in challenging a title decree constitutes gross laches and that writ jurisdiction cannot be used to adjudicate complex title disputes

On the merits, the Court found the project satisfied the 18m ROW requirement because the land is part of an "integrated layout" serviced by wider peripheral roads, rejecting a plot-isolated interpretation of the Master Plan

Regarding height and conformity under Clause 5.5, the Court held that "conformity" does not mean "identity"; since the zone is designated for residential group housing, vertical growth is permissible under current MPD-2021 norms despite older surrounding 3-story structures

On the environmental issue, the Court noted that specifically in light of the Hon'ble Supreme Court's order dated 12.08.2025 (accepting the CEC Report), the project could proceed with stringent safeguards even if technically within the Morphological Ridge, as the site was a flat, urbanized enclave

The Court deferred to the technical expertise of the DDA and MCD committees, finding no "patent illegality"

Held: (i) the Petitioners had locus standi as neighboring stakeholders but failed on merits; (ii) the challenge to title was barred by delay and lack of jurisdiction; (iii) the sanctions were validly issued under the 2018 Regulations and MPD-2021; and (iv) the environmental permissions were upheld per Supreme Court directions

The Court directed the Respondents to strictly adhere to sanctioned plans and environmental mitigation measures during construction. No costs were awarded
