In which House, the Janta Government failed to secure two-third majority for new clause under Article 368 for introducing referendum for effecting changes in certain basic features of the Constitution?

The Janata Government (1977-1979) introduced the 45th Constitutional Amendment Bill seeking to introduce referendum for changes to basic features. While it passed in Lok Sabha, it failed to secure the required two-thirds majority in Rajya Sabha. This demonstrates how the upper house acts as a check on constitutional amendments. State Legislatures and Legislative Councils are not directly involved in this process.
