At a press meet held in Tinsukia on Monday, Karmakar demanded that all judicial officials, including stenographers, clerks and computer typists associated with the legal system who are not conversant with Assamese language and appointed during the past five years, should be treated as illegal. Expressing serious concern over the present justice delivery system in the Brahmaputra Valley, Karmakar pointed out that it was mandatory to use and record evidence in language of the court. He alleged that there existed a nefarious lobby in the high court that was working against the interest of Assam and there were about 50 such judicial officers, besides a sizable staff appointed in recent times, who were working in lower courts of Assam, including two in Tinsukia court, he added.
