The program, promoted by the World Bank as a pro-poor, pro-transparency initiative, was undertaken to capitalize on the boom in nearby Chennai. The absence of clear land titles made extensive land purchases time consuming and expensive, and this was a bottleneck to large-scale development projects. As part of the program, the Tamil Nadu government declared that the digitized records would be the only evidence admissable in court for land claims, so the older records and less precise data that formed the basis of the Dalit claims lost any legal footing they had, and their claim was sunk.
