After receiving a case of corrective measures, the Executive Yuan or its subordinates should immediately make improvement or take appropriate actions. They are also obliged to reply to the Control Yuan in writing concerning what efforts they have made. If the work fails to be done within two months, the Control Yuan may question these organs. If they refuse to answer the question or if the explanation is unsatisfactory, the Control Yuan may initiate a case of censure or a case of impeachment against the head of the organization due to his failure to make reply.
