The website of IT dept contains pages and pages of instructions to the public. I know that the IT dept issues circulars to its dept people under section 119 of IT act.
 
Under which section/authority, the instruction in the website to the public are given ?
 
What are the legal standing of these instuctions? Can someone enlighten me on this?
