[3][4] In October 1996, during his second term as prime minister, he was abducted along with President Jean-Marie Léyé by members of the paramilitary Vanuatu Mobile Force, "disgruntled over a pay dispute".

[5] In 1997, while still serving as prime minister, he was implicated in a scheme to sell Vanuatuan passports to foreigners, and the Office of the Vanuatu Ombudsman recommended that he resign from his post.

While abroad, Vohor was charged with contempt for comments he had made in parliament about Chief Justice Vincent Lunabek, but in September 2004 the Supreme Court threw out the charges on the grounds that Vohor had not been given the proper chance to defend himself in court, and that, furthermore, his comments were protected by parliamentary privilege.

[7] Vohor gained international attention when, on 3 November 2004, while on a secret visit to Taipei, he established diplomatic relations with the Republic of China (Taiwan) without approval from the Council of Ministers.

The Council of Ministers voted to void the move and asserted Vanuatu's continued recognition of the People's Republic of China under its terms of the One-China policy.

On 1 December, Vohor punched (or pushed) the shoulder of the new ambassador from Beijing, Bao Shusheng, after being approached to explain why the flag of the Republic of China was still flying over a hotel in Port Vila.

Vohor then took the matter to the Court of Appeal,[9] but it also ruled against him; he was defeated in the no-confidence vote and replaced by Ham Lini.

On 27 July 2007, Vohor, who was serving as Minister of Public Utilities, allegedly assaulted an official from the Finance Ministry due to his pay being delayed.

Vohor was found to have accepted 1,000,000 vatu from Moana Carcasses MP, in return for support in a motion of no-confidence against the government of Joe Natuman.

He was pardoned by the President of Vanuatu, Tallis Obed Moses, in September 2021, which restores his eligibility to run for public office again.
