This document contains the original Supreme Court judgment for Daryao & Ors. vs. State of U.P. & Ors., delivered on March 27, 1961. The judgment primarily addresses the principle of 'res judicata' in relation to writ petitions filed under Article 32 of the Indian Constitution, particularly when a similar petition has already been dismissed by a High Court under Article 226. It clarifies the conditions under which a prior High Court decision acts as a bar to a subsequent Supreme Court petition. This judgment is crucial for legal practitioners, law students, and anyone interested in Indian constitutional law and civil procedure.
