If the Commissioner is satisfied with the application, then he/she will pass an order in writing registering the Trust or Institution under 12A of the Income Tax Act. In case the Commissioner is not satisfied with the application, then he/she can also pass an order in writing refusing to register the Trust or Institution.
You will get physical copy. I don't think it is on portal for downloading.
