Yes, a neighbour can be stopped from blocking natural light and air in Delhi, but only where you have established a specific legal right known as an easement of light and air, since simply enjoying natural light and air for years does not, by itself, automatically entitle a property owner to prevent a neighbour from constructing on their own land, and understanding this distinction is essential before pursuing legal action against a neighbouring construction project. Indian law recognizes the right to light and air as an easementary right under the Indian Easements Act, 1882, and Section 15 of the Act specifically provides that where the access and use of light or air to and for any building have been peaceably enjoyed as an easement, openly, and as of right, without interruption, for twenty years, the right to such light and air becomes absolute and can be legally enforced against a neighbour.

To succeed in stopping a neighbour from blocking natural light and air in Delhi, the claimant must prove that a specific window, opening, or defined aperture in their building has actually enjoyed a measurable and identifiable quantum of light and air for the full twenty-year prescriptive period, since Indian courts have consistently required proof of a substantial and appreciable diminution in the actual light and air that would otherwise be enjoyed, not merely some marginal or trivial reduction, and merely showing that a neighbour's new construction will somewhat reduce ambient natural light is generally insufficient; the claimant must demonstrate that the interference is substantial enough to render the affected room or space significantly less comfortable or usable for its ordinary purposes than it was before, according to the standards that have developed through consistent judicial interpretation of Section 15 of the Act.

Where the twenty-year prescriptive period has not yet been completed, meaning the window or opening in question has enjoyed light and air for a shorter duration, no enforceable legal right to light and air has yet accrued, and a neighbour is generally free to construct on their own land, even if it results in some reduction of light and air to the adjoining property, subject only to compliance with applicable municipal building bylaws and setback requirements enforced by the Municipal Corporation of Delhi or the Delhi Development Authority, which exist independently of easement law and address separate concerns about structural safety, fire access, and urban planning.

Once a valid right to light and air has been established under Section 15 of the Indian Easements Act, 1882, and a neighbour's proposed or ongoing construction threatens to substantially interfere with it, the appropriate remedy is to file a civil suit seeking a permanent injunction restraining the construction to the extent it would obstruct the established light and air, and where construction has already commenced or is imminent, an urgent application for a temporary injunction under Order 39 Rules 1 and 2 of the Code of Civil Procedure, 1908 becomes necessary to prevent the obstruction from being completed before the underlying dispute is fully adjudicated.
