In December 2010, when the Natapei government was ousted in a vote of no confidence, Carcasses supported his successor Sato Kilman, and obtained a post as Minister of Finance and Economic Management in the new government. Kilman was himself ousted in a vote of no confidence on 24 April 2011, however, and Carcasses lost his position in government. He recovered it three weeks later, on 13 May, when the court of appeal voided the election of Serge Vohor's new government on constitutional grounds, and the Kilman government was restored. This lasted for only a month; on 16 June, the Kilman premiership was itself voided on constitutional grounds by the Supreme Court's Chief Justice Vincent Lunabek, and Carcasses lost office once more. He regained it on 26 June when Kilman was restored as Prime Minister by Parliament, and reinstated his Cabinet.
