Which countries don't have a judicial system?

Most countries have some form of judicial system, but there are a few exceptions where formal judicial structures are either absent or severely limited. For example, in regions with ongoing conflict or instability, such as parts of Somalia and Afghanistan, traditional or informal systems may prevail over formal judicial institutions. Additionally, in some authoritarian regimes, the judicial system may be heavily influenced or controlled by the government, leading to a lack of true judicial independence. However, outright absence of any judicial system is extremely rare.
