Elektrooniline Riigi Teataja (commonly abbreviated eRT) is the web-based outlet for publication of laws and official announcements of the Republic of Estonia. It is modelled after the older paper-based publication, Riigi Teataja. Under Estonian law, Elektrooniline Riigi Teataja is since 1 June 2002[1] considered the authoritative reference source for laws of Estonia. Just like Riigi Teataja, eRT is published by Riigikantselei.
Since 1 January 2006, eRT was the only form of official publication for most Estonian laws, and paper-based Riigi Teataja issues were only printed occasionally, for checking purposes. The last issue of the paper version of Riigi Teataja was published on May 31, 2010.
