Madhava Reddy and G. Prabhakar for the Appellant. H.S. Gururaj Rao	 Subodh Markandeya	 Mrs. C. Markandeya	 W.A. Nomani and G. Seshagiri Rao for the Respondent. The Judgment of the Court was delivered by section RATNAVEL PANDIAN	 J. The State of Andhra Pradesh represented by the Director	 Anti Corruption Bureau	 Hydera bad has filed this criminal appeal challenging the correct ness of the Order dated 29.7.1988 of the High Court of Andhra Pradesh in Crime No. 7/ACB/Cr. II/84 dated 8.3.1984 on the file of the Special Judge for ACB & SPE quashing the First Information Report in exercise of its inherent powers under Section 482 of the Code of Criminal Procedure. A few facts relevant to decide this case may be stated: The respondent was selected to the Indian Police Service in the year 1953 and he worked in various capacities at different places. While he was working as Commissioner of Weights & Measures	 Government of Andhra Pradesh	 on a report dated 7.3. 1984 submitted by the Deputy Superintend ent of Police	 Anti Corruption Bureau	 a case was registered against him on 8.3. 1984 in Crime No. 7/ACB/Cr. II/84 under Section 5(2) read with Section 5(1)(e) of the prevention of Corruption Act	 1947 on the allegations that while function ing as Commissioner of Police and later as Vice Chairman of Andhra Pradesh Housing Board during the years 1978 82	 he ingulged in corrupt practices and acquired immovable assets either in his name or 749 in the name of his wife. The Anti Corruption Bureau after completing its investigation submitted its report on 22.4.1987 to its DirectorGeneral who in turn sent the same to the Government on 17.9. The Government accorded the necessary sanction for prosecution in G.O.Ms. 525 and 526 dated 16.9. In the meantime	 the respondent filed the criminal petition for quashing further proceedings pursuant to the registration of the First Information Re port	 inter alia	 contending that there had been lull in the investigation for fairly long spell causing inordinate delay and that the prosecution had not filed its report contem plated under Section 173 Cr. P.C. till he filed the petition for quashing the proceedings in November 1987 though the case was registered even in March 1984. The plea of the respondent was stoutly resisted by the appellant stating that the delay was occasioned on account of the dilatory tactics adopted by the respondent and the case was a complicated and timeconsuming one. The High Court has quashed the First Information Report on the ground that there was inordinate delay in the inves tigation. Aggrieved by that judgment	 the State has pre ferred this Criminal appeal. Mr. Madhava Reddy	 learned senior counsel appearing on behalf of the appellant took an exception to the observation of the learned Single Judge of the High Court reading: " . . I hold that wherever there is an inordinate delay on the part of the investigating agency in completing investigation	 the case merits quashing of the First Infor mation Report even . . . Generally. this Court will not quash the F.I.R. because it amounts to stopping of investigation	 but where there is an inordinate delay	 the same is a ground to quash even the F.I.R." and contended that the above observation is too wide a proposition and it will be detrimental to the prosecution in future under all circumstances	 regardless of the reasons therefor. Though we have decided to dispose of this appeal on some other ground	 the submission of Mr. Madhava Reddy on the above extracted observation of the High Court makes it necessary to examine the ques 750 tion whether a mere delay in the investigation of a criminal proceeding will by itself serve as a sufficient ground for quashing the proceedings in pursuance of the registration of the case notwithstanding whatever may be the reasons for the delay. This question has come up for determination in a number of cases wherein this Court has examined the right of an accused for a speedy investigation and trial in a crimi nal case in the light of Article 21 of the Constitution of India. There is no denying the fact that a lethargic and lacka daisical manner of investigation over a prolonged period makes an accused in a criminal proceeding to live every moment under extreme emotional and mental stress and strain and to remain always under a fear psychosis. Therefore	 it is imperative that if investigation of a criminal proceeding staggers on with tardy pace due to the indolence or ineffi ciency of the investigating agency causing unreasonable and substantial delay resulting in grave prejudice or disadvan tage to the accused	 the Court as the protector of the right and personal liberty of the citizen will step in and resort to the drastic remedy of quashing further proceedings in such investigation. While so	 there are offences of grave magnitude such as diabolical crimes of conspiracy or clandestine crimes com mitted by members of the underworld with their tentacles spread over various parts of the country or even abroad. The very nature of such offences would necessarily involve considerable time for unearthing the crimes and bringing the culprits to book. Therefore	 it is not possible to formulate inflexible guidelines or rigid principles of uniform appli cation for speedy investigation or to stipulate any arbi trary period of limitation within which investigation in a criminal case should be completed. The determination of the question whether the accused has been deprived of a fair trial on account of delayed or protracted investigation would also	 therefore	 depend on various factors including whether such delay was unreasona bly long or caused deliberately or intentionally to hamper the defence of the accused or whether such delay was inevi table in the nature of things or whether it was due to the dilatory tactics adopted by the accused. The Court	 in addition	 has to consider whether such delay on the part of the investigating agency has caused grave prejudice or disadvantage to the accused. The assessment of the above factors necessarily vary from case to case. It would	 therefore	 follow that no general and wide proposition 751 of law can be formulated that wherever there is inordinate delay on the part of the investigating agency in completing the investigation	 such delay	 ipso facto	 would provide ground for quashing the First Information Report or the proceedings arising therefrom. Our above view is supported by a decision of this Court in Raghubir Singh vs State of Bihar	 [1986] 4 SCC 481. Reference may also be had to Bell vs Director of Public Prosecutions of Jamaica and another	 [1985] 2 All England Law Reports 585 and the article in captioned 'The Power of the Courts to stay a Criminal Prosecution. ' It follows from the above observations that no general and wide proposition of law can be formulated that wherever there is any inordinate delay on the part of the investigat ing agency in completing the investigation	 such delay is a ground to quash the F.I.R. Reverting to the present case	 the respondent was placed under suspension pending enquiry into certain irregularities in the purchase of land as pointed out in the earlier part of this judgment. The State Government on the basis of the enquiry report passed orders for stopping further action and directed re instatement of the respondent into service with immediate effect by Order dated 5th September 1984. Accord ingly	 he was re instated and allowed to function as Con troller	 Weights & Measures	 Andhra Pradesh. However	 by subsequent order dated 5th July 1985	 the appellant (State Government) cancelled the aforesaid order dated 5th Septem ber 1984 and directed the respondent to show cause as to why the penalty of compulsory retirement should not be imposed on him. Thereupon	 the respondent filed Writ Petition No. 10670 of 1985 before the High Court of Andhra Pradesh	 seeking a writ of mandamus declaring the orders of the appellant contained in G.O. Rt. No. 2930	 GA (SC. C) Depart ment dated 5th July 1985 as arbitrary and unconstitutional	 and consequently to set aside the same by holding that the appellant was bound to give effect to the Orders contained in G.O. Rt. No. 4572	 GA (SC. C) Department dated 5th Sep tember 1984. This writ petition was transferred to the Central Administrative Tribunal	 Hyderabad Bench. The Tribu nal allowed the petition holding that the impugned order in G.O.Rt. No. 2930 dated 5th July 1985 is illegal and beyond the powers of the State Government. Aggrieved by the judgment of the Tribunal	 the State of Andhra Pradesh preferred a Special Leave Petition (Civil) No. 405 of 1987 752 before this Court	 and this Court by its Order dated 16.11.1988 dismissed the same. The said order reads as follows: "Having regard to the facts and circumstances of the case and specialty in view of the facts that the respondent has retired from service on attaining the age of superannuation	 we do not consider it a fit case for interference. It is accordingly dismissed. " Admittedly	 the appellant notified the date of retire ment of the respondent w.e.f. 30th April 1988 by G.O.Rt. No. 866 dated 10th March 1988. Accordingly	 the respondent was allowed to retire peacefully from service on attaimng the age of superannuation. The First Information Report and the consequent proceedings on the registration of the case were quashed by the High Court on 29.7.1988. Surprisingly	 the appellant accorded sanction for prosecution in G.O.Ms. 525 & 526 dated 16.9.1988 i.e. after nearly 50 days of the quashing of the First Information Report. In view of the above facts and circumstances and the various events following the suspension of the respondent culminating in his being allowed to retire on attaining the age of superannuation	 we are of the view that it is not a fit case for interference. The appeal is accordingly dismissed. N.P.V. Appeal dis missed.

A case was registered against the respondent	 an officer of the Indian Police Service	 under Section 5(2) read with Section 5(1)(e) of the Prevention of Corruption Act	 1947	 on 8.3.1984 but the investigation report was submitted to the Government on 17.9.1987. In November	 1987	 the respond ent filed a criminal petition for quashing further proceed ings pursuant to the registration of the First Information Report contending that there had been inordinate delay in the investigation and that the prosecution had not filed the report as contemplated under Section 173 Cr. P.C. till he filed the petition. The appellant contended that the delay was occasioned on account of dilatory tactics adopted by the respondent and that the case was a complicated and time consuming one. The High Court quashed the First Information Report and observed that wherever there was an inordinate delay on the part of the investigating agency in completing investigation	 the case merited quashing of the First Infor mation Report even. The State preferred an appeal in this Court contending that the High Court 's observation was too wide a proposition and it would be detrimental to the prosecution in future under all circumstances	 regardless of reasons therefor. Dismissing the appeal	 this Court	 HELD: 1.1 No general and wide proposition of law can be formulated that wherever there is inordinate delay on the part of the 747 investigating agency in completing the investigation	 such delay	 ipso facto	 would provide ground for quashing the First Information Report or the proceedings arising there from. [750H	 751A] 1.2 A lethargic and lackadaisical manner of investiga tion over a prolonged period makes an accused in a criminal proceeding to live every moment under extreme emotional and mental stress and strain and to remain always under a fear psychosis. Therefore	 it is imperative that if investigation of a criminal proceeding staggers on with tardy pace due to the indolence and inefficiency of the investigating agency causing unreasonable and substantial delay resulting in grave prejudice or disadvantage to the accused	 the Court as the protector of the right and personal liberty of the citizen will step in and resort to the drastic remedy of quashing further proceedings in such investigation. However	 there are offences of grave magnitude which would necessari ly involve considerable time for unearthing the crimes and bringing the culprits to book. Therefore	 it is not possible to formulate inflexible guidelines or rigid principles of uniform application for speedy investigation or to stipulate any arbitrary period of limitation within which investiga tion in a criminal case should be completed. [750B F] 1.3 The determination of the question whether the ac cused has been deprived of a fair trial on account of de layed or protracted investigation would also	 therefore	 depend on various factors including whether such delay was unreasonably long or caused deliberately or intentionally to hamper the defence of the accused or whether it was due to the dilatory tactics adopted by the accused. The Court	 in addition	 has to consider whether such delay on the part of the investigating agency has caused grave prejudice or disadvantage to the accused. The assessment of these factors necessarily vary from case to case. [750G H] Raghubir Singh vs State of Bihar	 [1986] 4 SCC 481	 relied on. Bell vs Director of Public Prosecutions of Jamaica and another	 [1985] 2 All England Law Reports 585	 referred to. The Power of the Courts to stay a Criminal Prosecution	 ' 	 referred to. In the instant case	 the respondent was placed under suspension pending enquiry but was reinstated on the basis of enquiry report and further action was stopped. However	 by a subsequent order dated 5th July	 1985 the earlier order was cancelled and a show cause notice for 748 his compulsory reitrement was issued. The Central Adminis trative Tribunal held that the order dated 5th July	 1985 was illegal and beyond the powers of State Government. This Court dismissed State 's Special Leave Petition. In the meantime	 the respondent was allowed by the appellant to retire peacefully from service on attaining the age of superannuation and the First Information Report and conse quent proceedings were quashed by the High Court. In these circumstances	 this is not a fit case for interference. [751D	 E	 G	 752A	 C E]
