Director appointment timeframe extended; substitution lengthens the permissible interval before mandatory appointment under company law. The amendment replaces the prescribed timeframe in Rule 6(1)(a) of the Companies (Appointment and Qualification of Directors) Rules, 2014, increasing the allowable period for filling specified director vacancies. It was made by the Central Government under the Companies Act and comes into force upon publication in the Official Gazette, thereby modifying the temporal compliance requirement for appointment of directors.
