The provisions of Article 70-2 of the Immigration Control Act also apply to the crimes set forth in that Article that were committed before this Act comes into effect. In this case, the phrase "without delay after having committed the act pertaining to the crime" in the proviso to that Article is replaced with "within 20 days from the date on which the Act on the Development of the Immigration Control Order and Other Relevant Acts Incidental to Accession to the Convention Relating to the Status of Refugees, etc. comes into effect".
