At which Congress Session was the Working Committee authorized to launch a programme of Civil Disobedience?

The Lahore Session of the Indian National Congress (December 1929) resolved to adopt Purna Swaraj and explicitly decided to launch a programme of civil disobedience under Gandhi’s leadership. Contemporary accounts of the session note that 31 December 1929 saw the tricolour hoisted and the decision to commence civil disobedience was taken as part of the move toward complete independence [1]. Summary accounts of the Lahore Congress likewise record that the session adopted complete independence as its goal and decided to launch the Civil Disobedience Movement, which directly led to Gandhi’s Dandi march in March 1930 and the nationwide salt satyagraha [2].
