②After receipt of a warrant, a Japan Fair Trade Commission staff member may seize postal items, correspondence, or documents related to telegrams that are stored or possessed by persons handling communication affairs pursuant to the provisions of laws and regulations and do not fall under the provisions of the preceding paragraph, to the extent that there are sufficient grounds to suspect each of the items are related to a criminal case.
