The Speaker of the Cook Islands Parliament, Norman George, says he is confident that the courts will overturn the decision by the Queen's Representative to dissolve Parliament.
Sir Frederick Goodwin's announcement on Monday followed a by-election last week which appeared to give the opposition a majority.
New elections are scheduled for September the 26th.
But Mr George says he and the opposition Cook Islands Party have already agreed to take legal action over what he calls the hijacking of Parliament.
He says he believes they will be able to reverse Sir Frederick's decision.
"'It is so wrong that it has to be corrected by our High Court, our Court of Appeal, and of course whatever decision they make will be looked at by the Pacific region, the Commonwealth and the whole world, as a precedent."
