Both the Congress and the League rejected the proposals due to the following reasons : 

1. The Congress opposed the plan which aimed at a division of the country. 

2. The power of the Viceroy remained unchanged as he was still responsible for defense affairs. 

3. No provision was made for the people of princely states to send their representatives to the constitution making body. 

4. Self-government seemed to be a long-term affair. Gandhiji condemned it as a ‘post-dated cheque on a crashing bank.’ 

5. The Muslims rejected the proposal as it did not ensure creation of Pakistan and fifty percent of the seats for the Muslim League with the Congress in the Interim Government. Hence, the Cripes Mission failed to pacify the Indians. 

Outcome of the rejection or the major event that followed its failure : The failure of Cripps Mission asserted that the British Government was not ready to transfer power to Indians. There was hardly any possibility of a consensus between the Congress and the British. Gandhiji lost trust in the British and his attitude towards them altered. The Congress also felt that the British were reluctant to concede to India the right to self-government. So, Gandhiji launched his ‘Quit India Movement 1942’.
