Tonga's prime minister Akilisi Pohiva has told parliament that leadership without morality is due to fail.
According to Matangi Tonga, he made the comment after being accused by Lord Nuku of interfering in Indonesia's affairs by speaking about concern for what Mr Pohiva claimed to be the ill treatment of West Papuans.
Mr Pohiva spoke at the United Nations last month when several Pacific countries voiced concerns about human rights abuses by Indonesian forces in Papua.
Lord Nuku said Indonesia had already responded that it didn't like Tonga's interference.
He said the Cabinet was convinced that what the PM did was right, but he was convinced that it clashed with the Constitution.
He proposed that they should bring in the Chief Justice to tell them who is right.
