What do we consider the political system of Guyana to be? On the one hand, there is an official who is both head of state and head of government, who is determined by nationwide plurality vote. On the other hand, the constitution, in Article 106, paragraph 6, states:
The Cabinet including the President shall resign if the Government is defeated by the vote of a majority of all the elected members of the National Assembly on a vote of confidence.
Thus the president is clearly subject to majority confidence, like a parliamentary head of government–President David Granger and his cabinet fell due to a vote in December, 2018. Superficially, this implies a form of elected prime-ministerial government (like Israel 1996–2001), in that an elected head of government, and the cabinet, must maintain confidence in order to stay in office. Thus we appear to have separate origin and fused survival. Moreover, the president has no veto power other than suspensory (article 170, para. 4-5), and no other constitutional legislative powers that can be used against the majority of parliament.
It is, however, questionable whether we should conceptualize the executive’s origin as separate. The president is elected as the designated candidate on the list of the party that wins a plurality. On this point, the constitution, at Art. 177, says, in part, that a list of candidates for parliament,
shall designate not more than one of those candidates as a Presidential candidate. An elector voting at such an election in favour of a list shall be deemed to be also voting in favour of the Presidential candidate named in the list.
There is thus no separate election for president. On the one hand, this could be classified as just another case of fused-ballot presidential election, like the Dominican Republic and Honduras have had at times in the past. (I do not generally consider these systems non-presidential just because voters can’t ticket-split between president and congress, although a case could be made for considering them in a distinct class.) On the other hand, defining the president as the head of a winning party list, rather than as a separate candidacy, could be said to be no more separate origin than we have in Botswana and South Africa (cases I consider unequivocally parliamentary). What is unclear to me is what happens in Guyana if the plurality list in the parliamentary election is opposed by a multiparty post-electoral majority in parliament. Is the head of the plurality list still president? It seems so. Yet Art. 106 implies such a leader would not remain in office.
It is thus unclear how this case should be classified, and I think I have tended to ignore it in the past. Now that I am planning no longer to ignore it, I need to decide if it is “parliamentary” or “hybrid.” There might be a case to be made that this is just a parliamentary system where the leader’s election only appears direct and separate. Or it could be that it is a hybrid of separate election but parliamentary-style fused survival through the no-confidence mechanism in Art. 106.
I should note that there is a constitutional office of Prime Minister, so unlike in Botswana or South Africa it might be odd to say that the “President” is really a prime minister on account of being dependent on parliamentary-majority confidence. However, the PM is clearly a subordinate appointee of the president (and also serves as Vice President, and the President may appoint others to be Vice Presidents as well). So I would not let this quirk determine which executive-type box I put the case in.
As for the country’s electoral system, it appears to be a straightforward case of two-tier PR. There are both regional multi-seat districts and a nationwide PR tier, and it seems there is full compensatory allocation. (See constitutional article 160 or the election results at Psephos.) This would make it one of the few two-tier PR systems outside of Europe (leaving aside the question of whether MMP–found in New Zealand, Lesotho, and Bolivia–is a sub-type of two-tier PR or not). Thus the case is valuable for my goal of maximum coverage of both simple and two-tier PR around the world. (For instance, my recent queries about small dependent territories and free-list systems, and ongoing efforts to make sense of remainder-pooling systems.)
But does Guyana have a parliamentary system, some sort of parliamentarized hybrid presidential system, or an elected prime-ministerial system?
