18. (1) The Board when it thinks fit may, and when required to do so by the Government shall, make an enquiry whether any recognised institution should cease to be a recognised institution. (2) If, on making such an enquiry and after considering all such information and reports as are referred to in the preceding section and making such further enquiry as may appear to it to be necessary, the Board is satisfied that the teaching facilities provided or other arrangements made in this connection by a recognised institution are not such as to secure an adequate standard of efficiency for the practice of the system of medicine taught in the institution, it shall make an order withdrawing the recognition: Provided that no order under this sub section shall be made unless the institution concerned has been given an opportunity to raise, within a specified time, the standard of teaching and examination to the satisfaction of the Board and the institution has, in the opinion of the Board, failed to do so.
