UNION OF INDIA vs CHAIRMAN, U.P.S.E.B. & ORS.

The Supreme Court addressed the jurisdiction of the Railways in constructing and maintaining transmission lines for power supply from NTPC, affirming that such actions fall within their statutory authority. The Court held that the Railways' power purchasing agreement with NTPC, established under the relevant regulations, legitimizes their operations despite UPSEB's objections. The Court ultimately ruled in favor of the Railways, allowing them to continue drawing power from NTPC without interference from UPSEB.
