Absence of storm water drains in Master Plans does not extinguish State ownership of 'B' Kharab lands.

The petitioners, an apartment owners’ association (Mantri Tranquil) and a residential welfare association (Royal Palms), challenged notices issued by the Bruhat Bengaluru Mahanagara Palike (BBMP) in 2014 and 2019 alleging encroachment over storm water drains (Rajakaluves).

Mantri Developers (Petitioner No. 2) contended that the land in Sy. Nos. 7, 9, and 13 of Gubbalala Village was converted for residential use and building plans were sanctioned by the BDA in 2007, with no mention of drains in the Comprehensive Development Plan (CDP) 1995.

Royal Palms contended similar approvals for Sy. No. 11.

Following a 2009 PIL (W.P.No. 31394/2009) regarding city-wide flooding, a survey identified that Mantri Tranquil had blocked/encroached upon 242.8 meters of drain, and Royal Palms had built over 'B' Kharab land (public utility).

An Expert Committee report in 2022 confirmed that critical drains (Drains I-IV) leading to Subramanyapura Lake were either blocked or of insufficient cross-section due to the petitioners' constructions.

Whether the absence of a storm water drain in the Master Plan/CDP or the grant of building sanctions by authorities estops the Government from identifying and restoring a pre-existing drain based on village maps.

Whether 'B' Kharab land, dedicated for public utilities like drains, can be diverted or claimed by private developers for residential construction.

Whether the court should direct the removal of constructions to restore the hydrological health of the area despite the passage of time.

The Court applied Section 67 of the Karnataka Land Revenue Act, 1964, which mandates that all public roads, streets, bridges, and specifically 'B' Kharab lands (public utilities/drains) vest absolutely in the State Government.

It further relied on Section 174 of the Karnataka Municipal Corporation Act, 1976, regarding the vesting of public property in the Corporation.

Regarding urban planning, the Court interpreted Section 12 of the Karnataka Town and Country Planning Act, 1961, noting that a Master Plan is a vision document for future land use and does not automatically divest the State of its title to water bodies or drains even if they are omitted.

The Court distinguished Sobha Developers Ltd. v. BBMP (2012), clarifies that planning errors do not create private rights over public drains.

The Court reasoned that 'B' Kharab land is reserved for the State for all time and cannot be privatized by mere omission in a Master Plan.

It rejected the petitioners’ reliance on BDA sanctions, noting that the Revenue Department is not a party to BDA plan approvals; thus, BDA's failure to identify a drain cannot override the primary evidence of the Village Map.

The Court observed that water naturally flows from higher to lower gradients, and the expert hydrological report proved that the petitioners' blocking of "Drain-II" and narrowing of others led to stagnation risks and environmental hazards.

It characterized the systematic exclusion of drains from development plans as potential collusion between developers and planning officials.

The Court emphasized that topographical surveys (like the British Great Trigonometrical Survey) remain the "beacon" for revenue administration, and modern technological advancements do not justify ignoring these historical arteries of water.

It held that public interest in flood prevention outweighs the interests of the occupants who built over 'B' Kharab land.

The Court ordered the BBMP to re-inspect the site on 28.02.2026.

The petitioners were granted a 15-day window from the inspection date to suggest and implement a viable alternative course for the drains (RCC retaining walls) at their own cost to ensure free flow to Subramanyapura Lake.

If the petitioners fail to provide a viable alternative within 15 days, the BBMP is directed to proceed with the demolition of encroachments and restore the drains in accordance with the Expert Committee's report.
