act and rule difference

'Act" always means a statute enacted through Parliament and superior of all in every context.

Rules and regulations are formed in the individual organizations on the basis of limited powers vested with authority.

EX: Right to Information states the rights of citizens in seeking information from the public under RTI Act.  The Act states that the public authorities are free to fix charges/fees for seeking information and for copying fees.

Central Govt fixed Rs.10/- as a fee and sends reply by Speed post and individual state governments have prescribed their own fee which is higher and some states collect such postage also.

Rules are framed by concerned department to implement laws passed by legislature.

What is the context for this query. To my knowledge, the Act and the Rule, as stated, are not in the statute book.

Sir,

Context is perhaps clear to my querry i.e. Payment of Gratuity Act 1972 and Payment of Gratuity (Rules) 1972.Alternatively, can I get link for statute book, which perhaps may help me to find out.

Thanks
