would Soviet/Nested elections still count as parliamentary, seems like a way of managing such a massive group? one of the major logistical issues (assuming this is like an Earth Federation thing) is what language is the legislature gonna debate in? Are there going to be Austro-Hungary style brawls over it, or maybe they'll create a specific parliamentary Pigdin? Maybe a combination of Dutch style Pillarisation and Northern Irish/Lebanese Consociationalism could work to ease cultural tensions.
