Extrality (Extraterritoriality or Diplomatic Immunity) is a legal concept that allows an exemption to privileged parties from the application or jurisdiction of local law. The actual exemption from restriction/s from local law may vary greatly in scope depending on the controlling power or powers. The privileged parties may range in nature from diplomats to ambassadors, to trade officials and more.
The term stems from the fiction that such persons or things are deemed not to be within the territory of the sovereign where they are actually present.
The stated reason for establishing extrality policies is to aid:
- Interstellar Trade (Duty-free Zones)
- Interstellar Relations (Political Relations w/Foreign Powers)
The major portion of a starport is surrounded by a barrier demarking the limit of Imperial extraterritoriality (often shortened to extrality). The region inside this is under direct Imperial authority and local planetary laws do not apply. Goods may be purchased here without duty, and taxes are limited to a small Imperial income tax and such customs duties as the Imperium levies. Violators of local laws, especially political "criminals," may find asylum and sanctuary from restrictive local regimes, but if the fugitive is sought for an offense that is also a violation of Imperial law (murder, most felonies, and so on), Imperial officials will hold and extradite the fugitive.
Depending on the nature of the planetary government, the extrality limit may be marked by a simple wire fence or more complex barriers resembling the Berlin Wall of old Terra. The latter is usually done to prevent citizens of the planet from leaving without authorization and to enforce local customs laws.
Although, strictly speaking, the law level of the starport permits any weapon to be carried openly, the Imperial laws against property damage, murder and extortion are rigidly enforced by Imperial authorities, backed up by Imperial military forces as necessary. The owners of most businesses frown on open displays of weaponry and will usually refuse to serve walking arsenals... and are usually fairly well equipped themselves.
Each facility has its own unique features, and the number of variants is almost equal to the number of downports (the part of a port that is on the surface of a planet). Almost every downport has an associated urbanization surrounding the downport (in many cases completely). Residential areas are often allowed inside the extrality barrier for employees of the port and its associated businesses.
Almost all interstellar polities have established a strong policy of extrality in their pre-spaceflight histories to aid trade and local economies. Such policies often come in the form of treaties and may follow other economic and legal considerations such as the standardization of currency (valuta).
