Summarize the following court judgment. iminal Appeal No.155 of 1965. M. R. Barot and R. Gopalakrishnan	 for the appellants. P. K. Chatterjee	 R. H. Dhebar and section P. Nayyar	 for the respondent. The Judgment of the Court was delivered by Hegde	J. The appellants in this appeal are two police officers. The first appellant Bhanuprasad Hariprasad Dave was the police Sub Inspector and the second appellant	 Rajuji Gambhirji	 was his writer constable in February 1963. At that time both of them were attached to the Navrangpura police station	 Ahmedabad. They were tried and convicted by the Special Judge	 Ahmedabad	 for offences under section 161 read with section 165 A of the Indian Penal Code and section 5 (1) (d) read with section 5 (2) of the Prevention of Corruption Act	 (No. 2 of 1947)	 and for those offences each of them was sentenced to suffer rigorous imprisonment for two and half years and a fine of Rs. 1	000	 in default to suffer further rigorous imprisonment for year. The judgment of the learned Special Judge was affirmed by the High Court 	of Gujarat. It is against that judgment	 this appeal has been filed	 after obtaining special leave from this Court. To state briefly	 the prosecution case is as follows : Ramanlal	 the complainant in this case	 wrote a postcard on February 11	 1963 to one Madhukanta	 a lady teacher	 requesting her to ask Chandrakanta	 another lady teacher working with her	 to meet him in connection with certain work. Therein he also wrote that he would be glad if Madhukanta could accompany Chandrakanta. The headmaster of the school where Madhukanta and Chandrakanta were working	 happened to read that postcard. She took Madhukanta to task for allowing strangers to write to her in that manner. Piqued by the conduct of Ramanlal	 Madhukanta made over the postcard in question to the first appellant	 probably with a request that Ramanlal might be pulled up for his conduct. On February 16	 1963	 the first appellant sent the second appellant to fetch Ramanlal to the police station. On his arrival at the police station	 Ramanlal was abused and slapped by the first appellant. With a view to got out of the situation. Ramanlal agreed to pay the sum demanded. He therefore asked the first appellant time for payment till the 18th. The first appellant agreed to the same. On the morning of 18th	 Ramanlal met the Deputy Superintendent of Police	 AntiCorruption Department	 and complained to him about the incident in question. He was asked to give a written complaint in that regard which he did. Thereafter he produced before the Dy. S.P. ten currency notes of Rs. 10 each. The numbers of those notes were noted and then those notes were treated with anthracene powder. Ramanlal was asked to give those notes to the first appellant if he made any further demand for bribe. Thereafter he was sent to the police station with the panch witness	 Dahyabhai. But when they went to the police station they found that the first appellant was not there. They were told that he had gone to attend court. Hence Raman lal and Dahyabhai returned to the office of the Anti Corruption Department and reported to the Dy. S.P. about the same. Under instructions from the Dy. S.P. he again went to the office of the Anti Corruption Department on the evening of that day with currency notes. Those notes were again treated with anthracene powder and their numbers noted. Ramanlal was again sent to the Police station with Dahyabhai on that evening at about 5 3o p.m. When they went there	 the first appellant was not there	 but the second appellant was there. He told them that the first appellant was expected in the station at any moment. Thereafter the second appellant	 Ramanlal and Dahyabhai went to a nearby tea shop and took tea. By the time they returned to the police 	station the first appellant was there. Ramanlal told the first appellant that he had brought the money. Then he asked him to pay the same to the second appellant who was in one of the rooms of the police station. When Ramanlal went to pay the money to the second appellant	 the first appellant took out the postcard written by Ramanlal to Madhukanta	 showed it to Dahyabhai and thereafter tore it to pieces and burnt it. Meanwhile Ramanlal went and paid the currency notes in question to the second appellant. While Ramanlal and Dahyabhai were in the police station	 police Sub Inspector Erulker and constable Santramji	 both belonging to the Anti Corruption Department	 were observing from a nearby compound the happenings in the police station. The second appellant immediately on receiving the notes in question left the police station. But he was followed by constable Santramji. From the police station the second appellant first went to the shop of one Sanghvi and changed one of the currencynotes. From there he went to the pan shop of Sendhalal and there changed three more currency notes. Thereafter constable Santramji was not able to keep track of him. Meanwhile when things did not go according to plan	 Ramanlal was somewhat confused. He after paying the amount to the second appellant L1OSup. Cl/68 3 26 straight rused back to the Dy. S.P. and told him what had happened at the police station. Immediately	 the Dy. He seized the burnt pieces of the postcard. Some of the unburnt pieces were recognised by Ramanlal as portions of the postcard written by him to Madhukanta. From there the Dy. S.P. proceeded to the shop of Sanghvi and Sendhalal and seized the currency notes changed in their shops by the second appellant. Their numbers tallied with the numbers of the notes earlier handed over to Ramanlal after being treated with anthracene powder. Those notes were full of anthracene powder. The same night the second appellant was arrested and at that time it was found there 	was considerable anthracene powder on his person. After in vestigation the appellants were prosecuted for the offences mentioned earlier. Both the trial court and the High Court have accepted the prosecution case. This Court being a court of special jurisdiction does not examine the evidence afresh except under exceptional circumstances. No good reasons were shown to us for departing from the ordinary rule. Hence we proceed on the basis that the findings of fact reached by the High Court are 	.correct. Before proceeding to examine the various contentions ad vanced on behalf of the appellants it is necessary to mention that in this case there were two investigations. As seen earlier the trap in this case was laid by the Dy. S.P.	 Anti Corruption Department. But when the case came up for trial before the learned Special Judge objection was taken to the trial of the case on the ground that in view of the provisions of the Bombay State Commissioner of Police Act	 1959	 the investigation in this case should have been made by a Superintendent of Police as there was a Police Commissioner for the city of Ahmedabad. The learned Special Judge accepted that contention and directed a fresh investigation to the extent possible by one of the Superintendents of Police. Because of the fresh investigation	 in respect of most of the prosecution witnesses	 the police diary contained	 two statements one recorded by the Dy.S.P. and the other by the S.P. in the course of the trial of the case	 several prosecution witnesses were alleged to have gone back on the statements given by them during investigation. While deposing in court 27 Madhukanta asserted that she had destroyed the postcard written by Ramanlal as soon as she read the same whereas both Ramanlal as well as the panch witness Dahyabhai had deposed that the first appellant had shown them the postcard in question. S.P. wherein she appears to have stated that she had given the postcard in question to the first appellant. Mr. Barot	 learned counsel for the appellants	 strenuously contended that in view of the order of the Special Judge	 directing re investigation	 in law	 the record of the investigation made by the Dy.S.P. stood wiped out	 and therefore Madhukanta should not have been cross examined with reference to the statement alleged to have been made by her during the first investigation. We are unable to accept this contention as correct. It is true that the first investigation was not in accordance with law	 but it is no sense non est. Investigation	 as held by this Court in section N. Bose vs State of Bihar(1)	 includes the laying of trap. That part of the investigation was	 admittedly done by the Dy. The statements recorded by the Dy. S.P. in the course of his investigation ' though the investigation in question was illegal	 (see	 H . N. Rishbud vs the State of Delhi(2)	 are still statements recorded by a police officer in the course of investigation under Chapter XIV of the Code of Criminal Procedure and consequently they fall within the scope of sections 161 and 162 of the said Code. Neither in Rishbud 's case(2) nor in section N. Bose 's case()	 where investigations had been carried on in contravention of section 5 A of the Prevention Corruption Act	 this Court considered those investigations as non est. Both the trial court and the High Court have accepted the evidence of Ramanlal and Dahyabhai in preference to that of Madhukanta that the first appellant was in possession of the postcard in question on February 18	 1963. This is essentially a finding of fact. In our judgment in coming to that conclusion those courts did not ignore any legal principle. It was next contended by the learned counsel for the appellants that the appellants were convicted solely on the basis of the testimony of Ramanlal	 the Dy.S.P. Erulker and Santramji	 who	 according to him	 are all interested witnesses and their evidence not having been corroborated by any independent evidence	 the same was insufficient to base the conviction of the appellants. Before examining this contention it may be mentioned that so far as Dahyabhai was concerned	 he appeared to have turned hostile to the prosecution at the trial. He supported the evidence of Ramanlal in some respects; but in most important respects he did not support the prosecution case. He admitted (1) Cr.A.109/1967	decided on March26	1968. (2) 11955] 1 S.C.R. 1150. 28 to have accompanied Ramanlal both in the morning and on the evening of the 18th. He also admitted that he and Ramanlal met a police Sub Inspector in the police station who showed them the postcard written by Ramanlal to Madhukanta. He also corroborated Ramanlal about the talk that Ramanlal had with that Sub Inspector	 in connection with the payment of bribe. But when it came to the question of identifying that Sub Inspector	 he denied that it was the first appellant. He also did not identify the second appellant. It was obvious that the had been gained over. So far as Sanghvi is concerned	 he admitted that a police constable in uniform came to his shop on the evening of the 18th and changed a ten rupee corrency note. But he stated that he was not able to say whether that constable was the second appellant. Sendhalal deposed that a person came to him on the evening of the 18th and changed three 'ten rupee currency notes. He also stated that he was unable to say whether it was the second appellant who changed those notes; he went a step further and stated that the person who came to his shop was not in uniform. But the fact remains that the currency notes seized from the shops of Sanghvi and Sendhalal are the very notes whose numbers had been earlier noted by the Dy. S.P. and further treated with anthracene. There is the evidence of constable Santramji to establish that the notes in question were changed at the shops of Sanghvi and Sendhalal by the second appellant. The trial court as well as the High Court accepted the evidence of Dahyabhai	 Sanghvi and Sendhalal to the extent it supported the prosecution case and rejected the rest. It was open for those courts to do so. Now coming back to the contention that the appellants could not have been convicted solely on the basis of the evidence of Ramanlal and the police witnesses	 we are of opinion that it is an untenable contention. The utmost that can be said against Ramanlal	 the Dy.S.P.	 Erulker and Santramji is that they are partisan witnesses as they were interested in the success of the trap laid by them. It cannot be said and it was not said that they were accomplices. Therefore	 the law does not require that their evidence should be corroborated before being accepted as sufficient to found a conviction. This position is placed beyond controversy by the decision of this Court in the State of Bihar vs Basawan Singh(1)	 wherein this Court laid down	 overruling the decision in Rao Shiv Bahadur Singh vs State of Vindhya Pra desh (2) that where the witnesses are not accomplices but are merely partisan or interested witnesses	 who are concerned in the success of the trap	 their evidence must be tested in the same way as any other interested evidence is tested	 and in a proper case	 the court may look for independent corroboration before convict (1) ; (2) 29 ing the accused person. We are unable to agree that any different rule was laid down in Major E. G. Barsay vs The State of Bombay(1). It must be remembered that the decision in Basawan Singh 's case(1) was given by a Bench of Five Judges and that decision was binding on the Bench that decided Major Barasay 's case(1). Some of the observations in Major Barasay 's case(1) no doubt support the contention of the appellants. But those observations must be confined to the peculiar facts of that case. It is now well settled by a series of decisions of this Court that while in the case of evidence of an accomplice	 no conviction can be based on his evidence unless it is corroborated in material particulars but as regards the evidence of a partisan witness it is open to a court to convict an accused person solely on the basis of that evidence	 if it is satisfied that that evidence is reliable. But it may in appropriate case look for corroboration. In the instant case	 the trial court and the High Court have fully accepted the evidence of Ramanlal	 the Dy. S.P.	 Erulker and Santramji. That being so	 it was open to them to convict the appellants solely on the basis of their evidence. That apart	 their evidence is substantially corroborated by the evidence of Dahyabhai	 Sanghvi and Sendhalal. in the case of partisan witnesses	 the corroboration that may be looked for is corroboration in a general way and not material corroboration as in the case of the evidence of accomplices. It was next contended that even if we accept the prosecution case in full	 no offence can be said to have been made out under section 161 of the Indian Penal Code. We are unable to accept that contention. To establish the offence under section 161 of the Indian Penal Code all that prosecution had to establish was that the appellants were public servants and that they had obtained illegal gratification for showing or forbearing to show	 in the exercise of their official functions	 favour or disfavour to Ramanlal. If he had used his official position to extract illegal gratification the requirements of the law is satisfied. This position is made clear by the decision of this Court in Mahesh Prasad vs The State of U.P. (3) and Dhaneshwar Narain Saxena vs The Delhi Administration (4). Lastly we come to the question whether the prosecution was barred by section 161 (1) of the Bombay Police Act	 1951 (Bombay Act 22 of 1951)	 which	 to the extent material for our present purpose	 says that in any case of alleged offences by a police officer or of a wrong alleged to have been done by such officer by any (1) [1962] 2 S.C.R.195. (2) ; (3) ; (4) ; 30 act done under colour or in excess of any such duty or authority as mentioned in that Act	 the prosecution shall not be entertained or shall be dismissed if instituted	 more than six months of the act complained of. Admittedly	 the prosecution in this case was instituted more than six months after February 18	 1963	 the day on which illegal gratification was obtained. In support of the contention that the prosecution is barred by limitation	 reliance was placed on the decision of this Court in Virupaxappa Veerappa Kadampur vs The State of Mysore(1). Therein a head constable was charged under section 218 of the Indian Penal Code. The prosecution case was that on February 23	 1954 on receipt of some information that some persons were smuggling ganja	 the headconstable arrested a person with a bundle containing 13 packets of ganja and seized them	 and in the panchnama he incorrectly showed the seizure of nine packets of ganja	 and that on the next day he however prepared a new report in which it was falsely recited that the person with the bundle ran away on seeing the police after throwing away the bundle containing nine packets of ganja. The allegation against the head constable was that the prepared a false report with the dishonest intention of saving the person concerned from whom the ganja was seized and who had been actually caught with ganja	 from legal punishment. This Court held that under section 161 of the Bombay Police Act	 1951	 the words "under colour of duty" have been used to include acts done under the cloak of duty	 even though not by virtue of the duty; that when the head constable prepared a false report he was using the existence of his legal duty as a cloak for his corrupt action and that	 therefore	 the act thus done in dereliction of his duty must be held to have been done "under colour of duty". The rule laid down in that decision is inapplicable to the facts of the present case. He by taking advantage of_that duty pre pared a false panchnama and false report and therefore it was held that what he did was under the colour of duty. In the present case the appellants cannot be said to have received the bribe under the colour of their duty. There was no connection between the duties to be performed by them and the receipt of the bribe in question. The facts of the present case bear some similarity to the facts in the State of Andhra Pradesh vs N. Venugapol(2) and the rule laid down therein bears on the question under discussion. This cannot be said to have been done under (1) [1963] Supp. 2 S.C.R. 6.(2) ; 31 colour of duty. The charge against the second appellant is that he aided the first appellant in his illegal activity. For the reasons mentioned above	 this appeal fails and the same is dismissed. The appellants who are on bail shall surrender forthwith to serve the remaining portion of the sentences imposed on them. Y.P. Appeal dismissed.

A postcard written by R to a lady M requesting her to ask another lady to meet him	 was made over to the first appellant a Police SubInspector. The first appellant asked the second appellant his writer constable to fetch R. On his arrival	 R was asked to pay money otherwise he would be harassed. R approached the Deputy Superintendent of Police	 Anti Corruption Department	 as a result of which a trap was laid and the currency notes treated with anthracene given to R for the payment R and one D went to the first appellant	 who directed R to pay it to the second appellant. The first appellant took Out the postcard	 tore it and burnt it	 while R paid the money. Another police Sub Inspector and constable both belonging to the Anti Corruption Department were keeping a watch from nearby compound. The second appellant went to two shot)s and changed some currency notes there. The Dy. S.P. searched the first appellant but nothing incriminating was found. he seized the burnt pieces of postcard	 sonic of the unburnt pieces were recognised by R. The Dy. S.P. seized the currency notes from the shops and their number tallied. The second appellant was arrested and considerable anthracene powder was found on his person. The appellants were tried tinder sections 161 ind 165A IPC and sections 5(1)(d) and 5(2) of the Prevention of Corruption Act by Special Judge	 Ahmedabad. An objection was taken to the trial that in view of Bombay State Commissioner of Police Act	 1959	 the investigation should have been made by a Superintendent of Police is there was a Police Commissioner in that city	 which was upheld and it fresh investigation ordered by a Superintendent of Police. Because of the fresh investigation	 in respect of most witnesses	 the police diary contained two statements one recorded by the Dv. S.P. and the other by the S.P. While deposing in the trial Court	 M asserted that she had destroyed the postcard as soon as she read it	 and she was cross examined by the prosecution in reference to her earlier statement to the Dy	 S.P	 to the effect that he had Liven the postcard to the first appellant. The Trial Court accepted the prosecution case and convicted the appellants	 which was upheld by the High Court. In appeal before this Court	 the appellants contended that (i) in view of the order of reinvestigation	 the record of the investigation made by the Dy. S.P.stood wiped out	 and therefore M could not have been crossexamined with reference thereof; (ii) the conviction could not solely be	based on the evidence of R and Police witnesses	 who were all interested witnesses; (iii) no offence. was made out under section 161 IPC	 as the prosecution had to establish that they were public servants and had obtained illegal gratification for showing or forbearing to show in exercise of their official 'functions	 favour	 or disfavour to R; and (iv) the Prosecution was barred 23 by limitation by section 161(1)of the Bombay Police Act	 1951 as it was instituted more than six months of the offence. HELD : The appeal must be dismissed. (i)Though the first investigation was not in accordance law	 but yet it was in no sense non est. Investigation includes laying of trap. That part of the investigation was done by the Dy. The Statements recorded by the Dy. S.P. in the course of his investigation	 though the investigation in question was illegal	 were still statements recorded by a police officer in the course of investigation under Chapter XIV of the Code of Criminal Procedure and consequently they fell within the scope of sections 161 and 162 of the Code.[27C F] S.N. Bose vs State of Bihar	 Cr. A. 109 of 1967 decided on March 26	 1968;H. N. Rishbud vs The State of Delhi. ; ; and The State of Bihar vs Basawan Singh	 ; 	 followed. (ii) While in the case of evidence of an accomplice no conviction can be based on his evidence unless it is corroborated in material particulars but 	is regards the evidence of a partisan witness it is open to a court to convict an accused solely on that evidence	 if it is satisfied that that evidence is reliable. But it may in appropriate case look for coroboration. In this case	 R. and the police witnesses could not be said to be accomplices	 and both the courts below have fully accepted their evidence. So it was open to them to convict the appellants on the basis of their evidence. That apart their evidence was substaintially coroborated by the evidence of D and the shopkeepers. [29B D] The State of Bihar vs Basawan Singh	 ; ; followed. Rao Shiv Bahadur Singh vs State of Vindhya Pradesh	 	 overruled. Major E.G. Barsay vs The State of Bombay; [1962] 2 S.C.R. 195	 distinguished. (iii) Offence under section 161 IPC was made out	 The question whether there was any offence which the first appellant could have investigated or not was irrelevant. If he had used his official position to extract illegal gratification	 the requirement of law was satisfied. [29F] Mahesh Prasad vs The State of U.P. ; ; Dhaneshwar Narain Saxena vs The Delhi Administration ; 	 followed. (iv) Section 161(1) of the Bombay Police	 Act	 1951 was inapplicable to this case. The appellants could not be said to have received bribe under the colour of their duty. There was no connection between the duties to he performed by them and the receipt of the bribe in question. All that could be	 said was that the first appellant a police officer	 taking advantage of his position as a police officer and availing himself of the opportunity afforded by the letter M handed over to him coerced R to pay illegal gratification to him. This could not be said 4to have been done " under colour of duty". The charge against the second appellant was that he aided the first appellant in his illegal activity. [30G 31A] The State of Andhra Pradesh vs N. Venugopal	 [1964] 3 S.C.R. 742	 referred to. Virupaxappa Veerappa Kadampur vs The State of Mysore	 [1963] Supp. 2 S.C.R. 6	 held inapplicable.
