Article 93

The Federal Government may conduct such inquiries

(whether by Commission or otherwise), authorize such surveys and collect and publish such statistics as it thinks fit, notwithstanding that such inquiries, surveys and collection and publication of statistics relate to a matter with regard to which the Legislature of a State may make laws.

It shall be the duty of the Government of a State, and of all officers and authorities thereof, to assist the Federal Government in the execution of its powers under this Article; and for this purpose the Federal Government may give such directions as it may deem necessary.
