As per my opinion Directorship in section 25 company is governed by section 252 of the companies act, 1956.
If it is a private company then 2 directors and if it is a public company then 3 directors.
Type of section 25 company
A section 25 company, which is proposed to be registered with limited liability, may either be a public limited company or a private limited company as may be decided by the promoters.
No requirement of minimum paid-up capital
Requirement of minimum paid-up capital of Rs. 1.00 Lac for a private limited and Rs. 5.00 Lacs for a public limited company shall not be applicable to a company registered u/s 25 of the Companies Act, 1956.
However views of other learned members solicited.
