RAJA SURIYA PAL SINGH vs THE STATE OF U.P. AND ANOTHER(AND OTHER CASES)

The Supreme Court upheld the validity of the Uttar Pradesh Zamindari Abolition and Land Reforms Act, 1950, stating that the jurisdiction to question its validity on compensation grounds is barred by Articles 31(4), 31-A, and 31-B of the Constitution. The Court clarified that 'public purpose' is not rigidly defined and varies with societal needs, and that Crown grants and charitable properties can be compulsorily acquired for public purposes. The judgment emphasized that explicit constitutional provisions take precedence over inferred limitations from the spirit of the Constitution.
