The leader of the main Cook Islands opposition party says last week's court decision on its electoral petition could lead to a hung parliament.
The Democratic Party has now successfully challenged the result in the Tamarua electorate after initially losing the seat in the July election.
To stay in government, the Cook Islands Party has to win a by-election in Mitiaro, a seat which the Democratic Party leader Wilkie Rasmussen says he is confident to win.
"It's always been a Democratic Party seat and we're confident that we will hold that seat this time round and then we'll get up to a situation where we could have a hung parliament; 12 [seats] for the government, ten for the Democratic Party and two for the One Cook Islands who at the moment are committed to working with the Democratic Party."
Wilkie Rasmussen says a hung parliament could mean that another general election may have to be held.
