Elektrooniline Riigi Teataja (commonly abbreviated eRT) is the web-based outlet for publication of laws and official announcements of the Republic of Estonia.
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.
Introduction of Elektrooniline Riigi Teataja made obsolete several earlier electronic databases of Estonian laws, most notably, the privately maintained Estlex system.
Most member countries of European Union now publish their laws electronically, but usually still without full legal force.
In order to ascertain integrity, eRT uses SSL cryptography for all legally binding content it serves.
