The Cook Islands Democratic Party, which is part of the caretaker government, says the courts have no ability to challenge the decision of the Queen's Representative to dissolve Parliament.
Sir Frederick Goodwin dissolved Parliament last week after a by-election gave the opposition an apparent majority.
New elections are to be held on 26th of September, but the opposition says it will take legal action over the dissolution.
However the Democratic Party says a decision by a Head of State, made under constitutional authority, is not open to judicial review.
The Democratic Party president, Makiuti Tongia, says the criticism of Sir Frederick's decision by MP and Speaker Norman George is unfortunate and as unwise as a misguided, rogue rocket.
