the Act are controlled by Sec.399 of the Act. The said provision states in what manner Secs.397 and 398 of the Act can be invoked. Admittedly, it does not enable a single share holder to move under Secs.397 and 398 of the Act. True, sub-sec.(4) of Sec.399 states that the Central Government may, if in its opinion circumstances exist which makes it just and equitable so to do, authorise any member or members of the company to apply to the Tribunal under Sec.397 or 398, notwithstanding that requirements of clause(a) or clause (b) as the case may be, of sub-sec(1) are not fulfilled. That is not a right with any corresponding duty, but a privilege given to a member or members of the company to apply to the Tribunal under Sec.399(1) and the discretionary power is vested with the Central Government to authorise such member or members to move under Secs.397 or 398 of the Act. That cannot be said as an alternative remedy available to the respondent as of right. That cannot oust jurisdiction of the civil court.
