The Likabali seat had fallen vacant after Health and Family Welfare Minister Jomde Kena passed away on September 4 this year at a hospital in Guwahati.
By-election to the Pakke-Kessang seat was necessitated after the Gauhati High Court declared null and void the election of Kameng Dolo from the said constituency in March 15, 2014 polls following an election petition filed against him by BJP nominee and former minister Atum Welly.
