Administrative Procedure Act Article 11

The jurisdiction of an administrative authority shall be determined according to the organic law or regulation thereof or other administrative law and/or regulations, as applicable.Where the jurisdiction of an administrative authority has undergone change as a result of amendment to its organic law or regulation, but no corresponding amendment has been made to the relevant administrative law or regulation to specify the competent authority, the fact of such change of jurisdiction may be publicly announced either by the authority having jurisdiction previously in conjunction with the authority conferred with jurisdiction in consequence of the amendment to such organic law or regulation or by the common superior authority of both authorities.Where an administrative authority has been dissolved or merged with another authority, the public announcement required by the preceding paragraph may be made solely by the authority conferred with jurisdiction as a result of amendment to such organic law or regulation.The public announcement made under the two preceding paragraphs shall become effective for the purpose of transfer of jurisdiction as of the third day from the date of announcement, unless otherwise specified in such announcement, in which case the transfer of jurisdiction shall become effective as of the effective date therein specified.No jurisdiction may be created or changed without authorization by law or regulation, as applicable.
