Since there is no world government which all countries recognize to arbitrate disputes over jurisdiction, sovereign powers can find themselves in conflict over which is the more appropriate venue to hear a case, or which country's laws should apply. These conflicts are sometimes resolved "de facto" by physical factors, such as which country has physical possession of a defendant or property, or sometimes by use of physical police or military force to seize people or property. A country with loose rule of law – for example an absolute monarchy with no independent judiciary – may arbitrarily choose to assert jurisdiction over a case without citing any particular justification. Such assertion can cause problems, such as encouraging other countries to take arbitrary actions over foreign citizens and property, or even provoking skirmishes or armed conflict.
