It's an agency that gives people the chance to appeal administrative decisions or cases which have been left by the courts of Switzerland. The most important intention is to safeguard and defend the interests of citizens. The overall idea behind the ETA is that the courts of Switzerland cannot get it right each time. Individuals who would like to file cases for an example should do this through the official website of this ETA. There are attorneys that deal with such matters only on a one time basis.
