He was arrested shortly after returning on 23 May 2020, again on charges of official corruption, stemming from the purchase of two generators from a company in Israel with which he was accused of having close ties. O'Neill said the allegations were politically motivated and that he had not personally benefitted from the procurement of the generators. The accusation was originally on misappropriation and official corruption, It was however turned into a more formal charge on following procedures instead of an outright criminal charge. The National Court dismissed the charge. O'Neill considered the case as an attempt to block him in the next general election and stated defiantly "you have to defeat me at an election". Prime Minister Marape was Minister of Finance at the time of the purchase and stated in court that the generators were not suitable for PNG and were gathering dust. In reply to a question by the MP Gary Juffa in 2019 it was stated that the diesel generators were too expensive to run for PNG power and that only one was serviceable. Vote of no confidence in Marape government He seemed to become more and more an isolated politician, but that appeared not to be true in the attempt to mount a vote of no confidence in the Marape government at the end of 2020. O'Neill was among several ex prime ministers and deputy prime ministers in the group asking for a vote of no confidence. O'Neill was a vocal leader among them. He accused the Marape government of irresponsible management of the economy and especially mismanagement of the resources sector: "Over 80 per cent of our economy depends on the resource sector, when you mismanage that the economy obviously suffers," and "No-one in their right mind shuts down an operating gold mine (Porgera) when the prices are at the top of its peak". O'Neill and Namah initiated the move towards a vote of no confidence, but they played no role in the vote for alternate prime minister. Both had to face court cases and this influenced their position. They were not contenders in the final vote that elected Pruaitch as alternate prime minister. The vote of no confidence foundered because the opposition appeared to be too fragmented in the choice of alternate prime minister to muster a majority. They split between supporters of Pruaitch and Sam Basil. The latter rejoined the government. Pruaitch
