By your definition yes. However the way Begnion's pseudo-Senate is set up parliamentary regulation is nothing more than facade to convince its citizens with the illusion of their voices being heard. It was said that the Senators were viewed as chosen people of the Goddess, thus implying a more theocratic system with the face of a parliamentary government, more evidence being that their ruler is also called the "Apostle" and is said to be guided by the voice of the Goddess.
I somehow can't help but feel we've gotten off track.
