For example, the Ministry of the Interior of Country X can stipulate how to proceed in certain situations for all police stations in the country. If several ministries issue a circular, one speaks of a joint circular (abbr. "Gem. RdErl").
Examples of circulars are the so-called radical decree of 1972, the Volmer decree on the issuing of visas (see: Visa affair ) of 2005, which was issued by the Foreign Office to the embassies and consulates and contained a simplified procedure for issuing visas or the so-called coffee Decree in the federal finance administration.
In some countries, we do not speak of a circular, but of a decree .
