If an administrative agency renders a disposition to refuse the permission or other approvals sought through the application, the agency must indicate the grounds for the disposition at the same time to an applicant; provided, however, that if the requirements for the permission or other approvals specified by laws and regulations or the review standards publicized have been clearly provided for by quantitative indexes or other objective indexes, and the fact that the application does not conform to those requirements are obvious from the entries in the written application or the attached documents, it is sufficient to indicate the grounds for the refusal when requested by the applicant.
When the disposition prescribed in the main clause of the preceding paragraph are to be rendered in writing, the grounds referred to in the preceding paragraph must be indicated in writing.
