Although Jammeh initially conceded defeat, on 9 December 2016 he rejected the result citing "unacceptable abnormalities". He subsequently announced that he had annulled the result, pending a new vote. He then filed a petition with the Supreme Court of The Gambia to contest the result. The court began hearing the case on 21 December. ECOWAS warned on 23 December that it would militarily intervene to uphold the results of the election if Jammeh didn't resign by 19 January. Jammeh appointed six new judges to the Supreme Court, having sacked all but one in 2015. The hearing was to be heard on 10 January, but was delayed until May. Jammeh stated that he would only relinquish the presidency if the court upheld the election result.
