Sales Promotion Employees Act 1976 - Help

It would be great if anyone could share your valuable knowledge regarding this act for the following points. I have gone through the act but it seems confusing. Your help for the following points would be truly appreciated.
Scope , extent of Application & Key provisions + (The rationale behind the act, for whom, how it has helped)
Does the employer has to register somewhere?
Penalties & offences + (Is this Audited? How it is caught and by whom?)
Thanks in advance.

All the answers to the question is already in the act.
Have you read the act ?

Yes sir i have read it, but i want to know the background behind this act as to why this act came into existence, what was the need and how it has improved the condition of the sales employees.

If you want to do academic research, you should do it on your own, asking someone to do it for you is not going to help really.
Again, the background is given in the preamble to the act.
The rest, there will be articles on it in google.
