Law enforcement in Hungary is split among the Police and Border Guards, and the Customs and Excise Authority. Since 2006, the Police has been subject to the Ministry of Justice, when the Ministry of Interior was re-structured to deal with Municipalities and Regional Development. Due to Hungary's accession to the Schengen Treaty, the Police and Border Guards were merged into a single national corps, with the Border Guards becoming Police Officers. This merger took place in January 2008. The Customs and Excise Authority remained to be subject to the Ministry of Finance.
