The leading pro-democracy MP in Tonga, Akilisi Pohiva, says legal action challenging constitutional amendments is likely to undermine the integrity of the king and the Tongan government.
Last year, the government amended the constitution to pave the way for legislation which has been criticised for curbing freedom of speech.
Mr Pohiva, Taimi o Tonga Publisher, Kalafi Moala, and others, are seeking a judicial review of the changes.
He expects the writ will be considered next week at the same time as Auckland mechanic Alani Taioni, appears in court to answer a charge of distributing an illegal publication in Tonga.
Mr Pohiva says he expects to win and if that happens it will have big ramifications for the Tongan government.
"If we win this case it's going to be a real disaster to the Tongan government, especially the king because he already signed for the legislation for the amendments to the constitution. So the other two legislation. It's going to be a big impact on the Tongans, not only that but on the integrity of His Majesty."
