The Directive Principles resemble the ‘Instrument of Instructions ‘enumerated in the Government of India Act of 1935. In the words of Dr B R Ambedkar, the Directive Principles are like the instrument of instructions, which were issued to the Governor-General and to the Governors of the colonies of India by the British Government under the Government of India Act of 1935. What is called Directive Principles is merely another name for the instrument of instructions. The only difference is that they are instructions to the legislature and the executive ‘.
