Transfer of registered office under section 18(3) governs procedure and excludes the condonation provision's application. An order of the Company Law Board for shifting a company's registered office from one State to another is governed exclusively by section 18(3), which operates independently and prescribes the procedure for effecting such transfers. Because section 18(3) contains no time limit for filing the CLB order, the condonation provision in section 637B(b) does not apply; the company remains on the register of the originating State until the order is filed and the Registrar certifies the transfer.
