special resolution or ordinary resolution

first of check the articles, what it says, if as per article need to pass Special Resolution (SR) then Pass SR and File form-23 otherwise Ordinary Resolution will serve the purpose and no need to file form-23 only form-5

Ya articles are need to be checked but in case if articles are also to be amended it definetely requires a Special Resolution and form 23 within 30 days.

Otherwise in case of increase in Authorised Capital udner Seciton 94 only Ordinary Resolution is required and form 5 is to be filed within 30 days.
