Having considered the facts and circumstances of the case, we are of the considered view that substantial and enormous delay on the part of the Investigating Officer will negate the purpose of justice as well as deterrent and rehabilitative effects of the criminal law. Fair and unbiased investigation is the fundamental canon of our criminal jurisprudence and is quite in conformity with the constitutional mandate enshrined in Articles 20 and 21 of the Constitution of India, hence, Investigating Officer cannot shy of his accountability protracting the investigation in the guise of any pretence. As such, it is provided that Senior Superintendent of Police, Prayagraj, i.e. respondent no.2, shall take effective steps to supervise over the matter issuing mandate to the Investigating Officer to proceed with the investigation in a very fair, unbiased and impartial manner, who will conclude it expeditiously preferably within three months from the date of production of a certified copy of this order avoiding unnecessary delay on flimsy ground. The respective parties are also expected to cooperate with the investigation on call of the Investigating Officer.
