The term de facto may also be used when there is no relevant law or standard, but a common practice is well established, although perhaps not quite universal. A de facto government is one that maintains itself by a display of force against the will of the rightful legal government and is successful, at least temporarily, in overturning the institutions of the rightful legal government by setting up its own in lieu thereof.
