Further -
Your main confusion point is section 167 says that director shall vacate the office if he is hit by any of the disqualifications mentioned u/s 164. But section 164 talks about ineligibility for appointment only.
Please see the following in latest module at page no. 3.24 and 3.25
(i) not eligible for appintment - only for sub clause (a) to (h)
then starts
(ii) not fliling returns etc... -
Detailed clarification: (i) is default of director - i.e. he is incapable to hold the office. in all these sub clauses the director shall vacate the office
(ii) its a default of company - not filing returns etc. for which directors are held liable....
did you noticed the difference? (i) is related to director personally and (ii) is related to company.
the real interpretation of section 167 is that, the director who is disqualified by "his own" defaults shall vacate the office for example if he is of unsound mind / insolvent / convicted by court etc etc.
But for company's default the single director is not responsible. There is a team. If we see logically, section can not say like that all directors shall vacate their office if company does not file returns. Let us consider an example, suppose there are 10 directors in ABC Ltd, and company failed to file returns for 3 years. Then as per wrong interpretation director shall vacate the office. offcourse why should we blame single director. If all 10 directors shall vacate the office then who will run the company yar? For not filing returns You cant blame only one director, if one is liable for vacation the others are also liable for vacation. (in practice manual question only name Mr kishor is mentioned that does not mean there are no other director in the said company)
The section does not intend to remove the director from office, Companies Act, 2013 just want to put a ban on the directors who enjoy their directorship even after default of company. Hence the only limitation is that he can not be reappointed.
Conclusion: if company has defaulted in filing returns then director SHALL NOT vacate the office, but if director himself is of unsound mind / insolvent / convicted by court / not paid calls etc etc... then he MUST VACATE the office as per section 167.
I hope this clears your doubt..
