1. This petition in a revisional attire proffers unique features of impeachment of the investigation of a sensational episode of assassination of a reputed journalist of the State who fell to multiple bullet injuries in the process of consorting his minor son back home from his school one fateful afternoon. The recorded challenge laid by the brother of the deceased though is against the verdict of acquittal of the respondent No. 3 indicted in Sessions Case No. 136(K)/03 vide judgment and order dated 28.7.2009 rendered by the learned Sessions Judge, Kamrup District, Guwahati, assiduous insistence for further investigation as the singular relief permeated the long drawn assertions on his behalf to espouse, as perceived, an uncompromising societal cause. While the investigating agency, the Central Bureau of Investigation (for short, hereinafter referred to as 'the CBI') and the State of Assam have endorsed the investigative pursuit, the maintainability of the petition in the present form and the tenability of the challenge in general have been sought to be vociferously assailed on behalf of the respondent No. 3.

2. We have heard Mr. A.K. Bhattacharyya, Senior Adv
