BNP led four-party alliance came into power with a landslide victory in October, 2001 parliamentary polls. This four-party alliance government became unpopular within a short period owing to her misdeeds, corruption, terrorism and Islamic fundamentalism etc. Under such condition government as of her electoral pledge brought changes in the constitution but sudden insertion of a clause regarding increase of retiring age of judges maligned her willingness regarding holding free and fair election. This change opened the path for opposition for creating strong movement against the government which led to the formation of 1/11 government in Bangladesh. This paper is intended to portray the socio-economic and political atmosphere which encouraged the government to make such amendment and at the same time which action of the government stimulated the opposition to create suffocating environment that paved the way for military takeover in January, 2007.
