In August 2019, Injia was appointed chair of a commission of inquiry into a controversial state loan of US$1,200,000,000 from the Swiss bank UBS used by the PNG government to buy a stake in the resource company Oil Search.
[2] On 9 November 2011, Sir Salamo Injia was suspended from the position of Chief Justice by the government after allegations that he had breached a contempt order and mismanaged court finances.
[4] In response, the Supreme Court ordered the arrest of O'Neill supporters, Deputy Prime Minister Belden Namah and Attorney-General Dr Allan Marat.
On 22 March 2012 Prime Minister O'Neill's administration introduced a new law, the Judicial Conduct Bill, empowering the government to suspend judges by referring them to a tribunal.
Police alleged that Injia illegally redirected into court coffers 213,000 Papua New Guinean kina (US$100,000) meant for Hinchliffe's adopted son, Timothy Sarri.
