Does common ownership of two parcels by itself authorise a planning authority to aggregate them into one development?

Tamil Nadu Combined Development and Building Rules, 2019 — r.41(1) — r.47(6) — Constitution of India — Art.300-A — Open space to be reserved (OSR) — Guideline value in lieu — Aggregation of adjoining extents — Tamil Nadu Combined Development and Building Rules, 2019 — r.41(1) — OSR land — Fragmented layouts read together — Held: The alternative of paying guideline value is available only where the development genuinely falls within the band between 3,000 and 10,000 square metres, and not where one integrated development is divided into successive paper layouts. (¶30) Tamil Nadu Combined Development and Building Rules, 2019 — r.47(6) — Composite development — Connecting factors must be identified — Held further: Common ownership alone does not authorise aggregation; the authority must identify contiguity, common acquisition, unity of access or design, temporal proximity or a sequence revealing fragmentation before treating two parcels as one development. (¶31, 32) Tamil Nadu Combined Development and Building Rules, 2019 — r.41(1)(c) — Administrative instructions — Monetary alternative not enlarged — Held further: Administrative instructions may guide delegation, valuation and implementation, but cannot enlarge the monetary alternative beyond the class of developments to which the Rules make it available. (¶36) Constitution of India — Art.300-A — Right to property — Statutory condition of development permission — Held further: Open space required to be reserved by duly framed statutory Rules is a lawful condition of development permission and not deprivation of property without authority of law. Writ petition dismissed. (¶41, 47)
