1.6. Contiguous zone
It is a band of water extending from the outer edge of the territorial sea to up to 24 nautical miles (44 km) from the baseline, within which a state can exert limited control for the purpose of preventing or punishing "infringement of its customs, fiscal, immigration or sanitary laws and regulations within its territory or territorial sea". This will typically be 12 nautical miles (22 km) wide, but could be more (if a state has chosen to claim a territorial sea of less than 12 nautical miles), or less, if it would otherwise overlap another state's contiguous zone. However, unlike the territorial sea there is no standard rule for resolving such conflicts, and the states in question must negotiate their own compromise.
