How these provisions fit together

Sections 21 and 22 conclude the incorporation-related chapter with rules on company authentication and instruments. Section 23 begins Chapter III and identifies methods of issuing securities. The following provisions regulate public offers, prospectus disclosures and advertisements, shelf and red herring prospectuses, application forms, liability for misleading prospectuses, fraudulent inducement, personation, allotment and stock-exchange permission.

Because securities law operates alongside the Companies Act, listed companies and companies proposing to list should also check the current SEBI framework and stock-exchange requirements. Companies should verify the latest MCA rules and notifications before taking filing or compliance action.
