A Political Mission: Monitoring Certain Aspects of the Governments Work
It is their task to scrutinise the way the Federal Government conducts its business regarding specific matters and to investigate actual conditions and events. They do not, however, have the right to hold representatives of the Federal Government responsible or make them suffer the consequences of their actions.
These rights are only exercised by the National Council, to whom the Federal Constitutional Law has, for instance given the right to pass a vote of no confidence against a Minister or to impeach him/her.
There is a basic distinction between investigating committees and court proceedings. The former do not settle disputes but find facts. Their findings cannot be appealed against. There are no defendants, and accordingly informants (experts or otherwise) testify to certain facts or circumstances rather than for or against a defendant.
