In the Satogeko City Special Autonomous Region, the sole party running is the Communist Party. However, outside of Satogeko City they are ineligible for running in elections. Despite this, they are allowed to send 20 representatives and one Senator into federal Parliament to speak on behalf of Satogeko City.

Though Grennia operates officially in a bicameral system, in practice the small size of the Senate limits it to being not much more
than a rubber stamp for the House of Representatives.
