The colonial assembly open to any extrasolar state with a human population of over 500,000 in one system. That includes any states on a planet or moon, a union of smaller states under one banner, or even an entire allied system. Any corporation headquartered in Sol may also gain membership of the Colonial Assembly. In 2547, a radical group of Skrell separatists applied for membership in the Colonial Assembly, they were denied in order to maintain a positive relationship with the Skrell, but it sparked a debate over theoretically allowing Xeno-Sapients into SolGov in the future that has not been resolved to date. Six seats on the Colonial Assembly belong to elected representatives from the Solar Assembly, which typically change every year. While the ability to approve major military action rests with the Solar Assembly, the Colonial Assembly may veto such an action with a majority vote of more than 2/3 of the members, though this hasn't occurred yet. Organizations containing human members, but not eligible or desiring to sit on the Colonial Assembly may request observer status. The Free Trade Union is one of the most respected of the observers, due to its influence in a large swathe of human population, and it has been suggested on multiple occasions, without result, that they be given voting status, despite their lack of borders or centralized organization.
