Parallel plane theory
Parallel plane theory is a micropatriological position which holds that micronational sovereignty over a people or territory does not preclude macronational sovereignty from extending there simultaneously, and that micronations should not try to become macronations. The theory was first put forward by Jordan Brizendine in August 2017, who successfully proposed motions in Delvera and at the Congress of Colo (a conference of delegates from Delvera, the North American Confederation and Karnia-Ruthenia) which stated that "micronations and macronations exist on separate, parallel planes whereby their duties and responsibilities do not overlap." The theory was developed further in early 2018 by Ives Blackwood and Glastieven T in the context of New Secessionism, with the two arguing that groups of friends held a position on the micronational plane which corresponded to that held by proto-nations on the macronational plane, though Blackwood later repudiated parallel plane theory.
Contemporary use of parallel plane theory
Some micronations make claims similar to those of parallel plane theory without identifying with the version developed by Brizendine, Blackwood and T.
Whilst the Empire of Adammia has never identified with parallel plane theory, its constitution (the Supreme Directive) states that "the laws of surrounding macronations should be upheld" and it is a principle of the law of Adammia that, whilst "the Empire can create law which contradicts macronational law, macronational law holds precedence, and contradicting it only amounts to a symbolic gesture." In addition, "the Adammic government does not enforce macronational law, though it does obey it for the most part," and "macronational law is not de-jure considered part of Adammic law." This amounts to the same thing as parallel plane theory, with Adammic law existing on a separate, parallel plane beneath English law, and is compatible with the final two terms of the Resolution.
Commonwealth of Deseret
The 2018 constitution of the Commonwealth of Deseret describes the state as "existing imperium in imperio within the United States" (imperium in imperio is Latin for a state within a state and is used in English to describe both deep states within governments and other forces that operate with sovereign-like impunity within other polities).
The Republic of West Who, according to its MicroWiki entry, "refers to itself as a 'domestic dependent nation', claiming status similar to a Native American tribal nation in the USA. Although not Native Americans, the citizens of West Who claim domestic dependent status." This would be similar to parallel plane theory—indeed, the example of Indian tribal government was cited as an inspiration for the theory by Blackwood and T. However, West Who has a sign at its border which says "leaving USA", which would not be true for either a domestic dependent nation or a micronation that used parallel plane theory.
