months from the date of the said order but nothing happened till 27th February, 2007 when, after receipt of notice in the second petition preferred by the appellant complaining about delay in investigation, the Superintendent of Police, Muzaffarpur directed the Deputy Superintendent of Police to complete the investigation. It was only thereafter that a fresh chargesheet is stated to have been filed on 1st May, 2007. It is also pertinent to note that even till date, learned counsel for the State is not sure whether a sanction for prosecuting the appellant is required and if so, whether it has been granted or not. We have no hesitation in holding that at least for the period from 7th December, 1990 till 28th February, 2007 there is no explanation whatsoever for the delay in investigation. Even the direction issued by the High Court seems to have had no effect on the prosecution and they slept over the matter for almost seventeen years. Nothing could be pointed out by the State, for from being established to show that the delay in investigation or trial was in any way attributable to the appellant. The prosecution has failed to show any exceptional circumstance which could possibly be taken into consideration for condoning a callous and inordinate delay of more than two decades in investigations and the trial. The said delay cannot, in any way, be said to be arising from any default on the part of the appellant. Thus, on facts in hand, in our opinion, the stated delay clearly violates the constitutional guarantee of a speedy investigation and trial under Article 21 of the Constitution. We feel that under these circumstances, further continuance of criminal proceedings, pending against the appellant in the court of Special Judge, Muzaffarpur, is unwarranted and despite the fact that allegations against him are quite serious, they deserve to be quashed.”
