Public interest defined by turnover and stakeholder interests, permitting conversion of private companies into public companies. Conceptualises public interest to include creditors, consumers, employees and the State, not merely public shareholdings; and explains that turnover was incorporated in the Companies (Amendment) Act, 1974 as a criterion to convert a private company into a public company under section 43A, advising authorities to apply these stakeholder and turnover factors when assessing public interest.
