Evaluate the jurisprudential legacy of the S.R. Bommai v. Union of India (1994) verdict concerning Centre-State relations:
1. The Supreme Court established that administrative inefficiency constitutes a total failure of constitutional machinery.
2. The judgment institutionalized the Sarkaria Commission's doctrine, validating Centre interventions in cases of hung assemblies.
3. The verdict authorized state governments to disregard Central directives without facing Article 356 consequences.
