Criminal Appeal No. 461 of 1987.
From the Judgment and Order dated 20.5.1987 of the Delhi High Court in Criminal Revision No. 105 of 1987.
Ashok Desai, Additional Solicitor General, P.K. Chaube, G. Venkatesh Rao, Ms. A. Subhashini and P.K. Choudhary for the Appellant.
R.K. Garg, J.P. Pathak and P.H. Parekh for the Respondent.
The Judgment of the CoUrt was delivered by section RATNAVEL PANDIAN, J.
The State represented by C.B.I., New Delhi has directed this appeal against the Order dated 20.5.1987 of the High Court of Delhi passed in Criminal Revision No. 105 of 1987 dismissing the petition of the petitioner in limine.
The relevant facts which have given rise to this appeal can be stated thus: The respondent, S.J. Choudhary is taking his trial before the Additional Sessions Judge, New Delhi for the offences under Section 302 I.P.C. and Sections 3 and 4 of the Explosive Substances Act in Sessions Case No. 36 of 1983.
According to the prosecution that on 2.10.1982 at about 5.45 p.m., the deceased in this case, namely, Krishan Sikand received a parcel addressed to him.
The deceased being unaware of the camouflaged contents opened the parcel which on opening exploded resulting in the instantaneous death of the deceased.
Relating to this incident, a case was registered at Hazrat Nizamuddin Police Station as FIR No. 305 dated 2.10.1982.
The investigation was taken up by the police of the said police station.
Thereafter, the investi gation was transferred to Crime Branch, Delhi on the very next day i.e. on 3.10.1982 and finally in March 1983 to the Central Bureau of Investigation where it was registered as case RC 3/83 CBI/DSPE/CIUI(P)/New Delhi.
The respondent/accused was arrested by the C.B.I. on 1.8.83.
Under the orders of Court, the 126 custody of the respondent was handed over to the CBI for sometime.
After completing the investigator the CBI laid the charge sheet on 28.10.1983.
Presently, the case is pending trial before the Addi tional Sessions Judge, Delhi.
While the petitioner in the SLP, filed in August, 1987 would state that as many as 63 prosecution witnesses have been examined and PW 64 is in the witness box, the respondent in his affidavit dated 21.2.
1990 has stated that so far 67 witnesses have been examined.
Be that as it may, according to the prosecution the cover of the device parcel containing camouflaged live hand grenade was found pasted with a typewritten name and address of the deceased, Krishan Sikand on a white slip and the explosion of the hand grenade resulted in the shattering of the materials into pieces inclusive of the said slip.
The police collected from the scene of incident the typewritten pieces of the paper in which the grenade had been wrapped amongst the debris and remanents which were sent to the Central Forensic Science Laboratory for examination and expert opinion.
In the laboratory, the parcel sent by the Investigating Agency for examination was opened by PW 61, Dr. G.R. Prasad, Head of the Ballistic Division on 12.10.1982.
He while examining the contents of the parcel succeeded in partially reconstructing the typewritten name and address of the deceased from the shattered pieces of the slip.
It is the version of the prosecution that on 5.8.83, while the respondent was in the custody of the CBI pursuant to the order of the Court, he made a voluntary confession which led to the discovery of the fact that the address on the aforesaid parcel was got typed by him from a commercial college namely, Janta Commercial College at I 43, Lajpat Nagar II, New Delhi.
The Investigating Agency took the specimen of typing prints from the 13 English typewriters found in the said college.
The re constructed typed address and the specimen type prints were examined by Sh.
S.K. Gupta.
Head of Document Division in the Central Forensic Science Laboratory.
Mr. S.K. Gupta gave his opinion that on balance of similarities and dissimilarities, it is a asona ble to conclude that the typescripts found on the slip pasted on the wrapper of the parcel collected from the scene have been typed from one of the machines of the Janta Com mercial College as both the impressions are identical.
Now, the prosecution wants to examine Mr. S.K. Gupta as an expert to prove the above fact.
This request of the prosecution to examine Mr. S.K. Gupta was stoutly resisted by the learned counsel of the accused on the ground that the evidence of such typewriting expert is 127 inadmissible under Section 45 of the Indian Evidence Act as it does not fall within its ambit.
It seems from the. im pugned order that several decisions were cited at the Bar by both the parties but the Trial Court on the strength of certain observations made by this Court in Hanumant & Anr.
vs State of Madhya Pradesh, [1952] SCR 1091 dismissed the prayer of the prosecution holding thus: "It shows that Hon 'ble Judges of the Supreme Court meant that such evidence cannot be brought on record and be evaluated by the Court.
It is well settled that if their Lordships of the Supreme Court clearly intended to declare the law on a particular point then even though the observa tions may be 'obiter dictum ', they are nevertheless binding upon the High Court and subordinate Courts.
Under these circumstances, I uphold the objections raised by the counsel of the accused and order that Sh.
S.K. Gupta, who is sought to be examined as an expert on type written documents cannot be examined to give evidence on this point.
" On being dissatisfied with the above order of the High Court, this criminal appeal is filed by the State.
For proper understanding and appreciation of the ques tion involved in this case, the relevant portion of the observation of this Court in Hanurnant 's case on the strength of which the High Court has passed the impugned order may be reproduced hereunder: "Next it was argued that the letter was not typed on the office typewriter that was in use in those days, viz. article B and that it had been typed on the typewriter article A which did not reach Nagpur till the end of 1946.
On this point evidence of certain experts was led.
The High Court rightly held that opinions of such experts were not admissible under the Indian Evidence Act as they did not fail within the ambit of Section 45 of the Act.
This view of the High Court was not contested before us.
It is curious that the learned Judge in the High Court, though he held that the evidence of the experts was inadmissible, proceeded nevertheless to discuss it and placed some reliance on it." Though a lengthy argument was advanced by the respective 128 counsel for both the parties by citing a series of decisions in support of their respective contentions, we are not adverting to all those contentions except to the relevant one, as we are of the view that the matter requires an in depth analysis and examination by a larger Bench in view of the observation in Hanumant 's case.
The learned Solicitor General has submitted that the words Science or Art ' occurring in Section 45 of the Indian Evidence Act should be given wide and liberal construction so as to cover all ranches of specialised knowledge to the formation of opinion, that by the march of science, the evidence of expert regarding type script has assumed impor tance, that such expert evidence on type script needs to be considered at par with the evidence of other experts brought within the ambit of Section 45 of the Evidence Act, and therefore, the expert opinion of Mr. S.K. Gupta cannot be shut out as being inadmissible.
According to him, the brief observation of this Court in Hanumant 's case (supra) cannot be construed as ratio decidendi binding on this Court or even obiter dictum but it is only a passing observation as there was no issue in that case as to whether the expert 's testimony on type script was admissible or not under the Evidence Act and consequently there was no discussion of law on that subject and in fact, there was no contest on the question of the admissibility of the evidence of an expert regarding typed documents.
He would reiterate that the judgment in Hanumant 's case has not declared the law in regard to the admissibility of the testimony of an expert in regard to typescript and that the learned Judges have pro nounced no independent opinion upon the same.
In support of this submission, firstly he drew our attention to the fol lowing passage appearing in Woodrofee and Ameerali 's Law of Evidence, which reads thus: "The Supreme Court has held in Hanumant v, State of M.P. that the opinion of an expert that a particular letter was typed on a particular typewriting machine does not fall within the ambit of section 45 of the Evidence Act and it is not admissible.
It is respectfully submitted it may require consideration in the light of the modern knowledge indicated to some extent by the research materials which show that detection of forgeries of typewritten documents has become an integral part of the science of questioned documents.
" Secondly, he brought to the notice of this Court the opinion expressed by the Law Commission in its 69th Report (Vol. IV) in Chap 129 ter 17 captioned 'Opinion of Expert ' wherein the Law Commis sion after referring to the decision in Hanumant 's case stated thus: "17.26 One could regard these observations as not laying down a definite view on the subject.
But the words "rightly held" could be construed as approving the negative view.
17.31.
We, therefore, recommend that Section 45 should be amended so as to include identity of typewriting".
According to the learned Solicitor General, as viewed by Woodrofee and Arneerali in 'Law of Evidence ' and by the Law Commission in its 69th Report, the word 'science ' occurring in Section 45 should be held comprehensive enough to include the opinion of an expert in regard to the transcript as well.
But the acceptability or otherwise of an expert testi mony on typewritten documents would depend upon the satis faction of the Court about the specialised skill and experi ence of that expert on that subject.
Finally, he requested that this Court notwithstanding the passing observation in Hanurnant 's case be pleased to examine in detail the ques tion of the admissibility or otherwise of an expert testimo ny on type script and lay down the law on this subject.
Mr. R.K. Garg, senior counsel appearing on behalf of the respondent vehemently urged that the observation in Hanu mant 's case cannot be discarded or brushed aside as a pass ing observation and if that argument is to be accepted by treating the view expressed by this Court as gratis dicta and to declare law on the subject ignoring the view in Hanumant 's case it would be tantamount to saying that the view expressed by the learned three Judges in that case as having been wrongly held and therefore, the argument of the learned Solicitor General has to be discountenanced.
The proceeding of the trial which has already been considerably delayed on this issue which is only academic so far as this case is concerned and so the respondent should not be sub jected to immeasurable hardship.
According to him, the High Court has passed this impugned order only on the strength of the observation in Hanumant 's case and rejected the plea of the prosecution to permit it to examine Sh.
S.K. Gupta as an expert and, therefore, the impugned order can neither said to be incorrect nor it calls for any interference.
He adds that this Court should not dissent lightly from the previous decision of this Court merely on the ground that the con trary view appears to be preferable and that the power of review must be exercised with due care and caution and that too only for advancing the public well being in the light of the surrounding cir 130 cumstances.
In support of this submission, he places reli ance in The Bengal Immunity Company Ltd. vs The State of Bihar & Ors., at 630.
He continues to state that this Court should exercise its discretionary jurisdic tion under Article 136 of the Constitution of India only in cases where there is violation of the principles of natural justice, causing substantial and grave injustice to parties or which raise important principles of law requiring eluci dation and final decision of this Court or which disclose such of the exceptional or special circumstances which merit the consideration of this Court on a particular issue.
He cites the decision of this Court in Bengal Chemical & Phar maceutical Works Ltd. Calcutta vs Their Workmen, ; at 140 in support of his later submission.
Finally, he states that the facts and circumstances of the case on hand do not warrant examination of the request made by the appellant.
After bestowing our anxious consideration on the ques tion of law involved, we without expressing any view at this stage on the observation made in Hanumant 's case feel that the question with regard to the admissibility of the opinion of an expert on type script should be examined in detail and decided.
Needless to say that by the march of time, there is rapid development in the field of forensic science and, therefore, it has become imperative to match the said march of modern vistas of scientific knowledge, the question whether the opinion of an expert in regard to type script would fall within the ambit of Section 45 of the Evidence Act has to be decided.
In fact, when the SLP in this matter came up for admission, the Bench considering the importance of the question involved made the following order: "Special leave granted.
Since the question involved is important and is involved in many cases, it is desirable that it should be heard as early as possible and the matter be mentioned to Hon 'ble the Chief Justice for appropriate directions.
" Taking the overall view of this matter, we feel that this important question of law involved in this case is to be examined in detail and decided by a larger Bench as the judgment in Hanumant 's case was rendered by three learned Judges of this Court.
Since the matter is urgent, it may be posted for hearing at an earliest point of time so that the trial of the case may not be further delayed.

Summary:
A device parcel containing camouflaged live hand grenade exploded in the hands of the addressee resulting in his instantaneous death.
The police collected from the scene of incident the typewritten pieces of the paper in which the grenade had been wrapped and sent them to the Central Foren sic Science Laboratory where they succeeded in partially reconstructing the name and address of the deceased.
These were then examined by the Head of the Document Division in the said Laboratory with reference to the specimen of typing prints taken from the commercial college where they were alleged to have been got typed.
He opined that on balance of similarities and dissimilarities it was reasonable to con clude that the type scripts found on the slip pasted on the wrapper of the parcel had been typed from one, of the ma chines of the college as both the impressions were identi cal.
At the trial the prosecution wanted to examine the said expert to prove the fact.
This was resisted by the defence on the ground that the evidence of such typewriting expert was inadmissible under section 45 of the Indian Evidence Act as it did not fall within its ambit.
The trial court relying on the observations to that effect in Hanumant & Anr.
vs State of Madhya Pradesh, [1952] SCR 1091, dismissed the prayer.
The High Court dismissed the State 's revision petition in limine.
In the appeal by the State it was submitted that the word 'science ' occurring in section 45 of the Evidence Act should be held comprehensive enough to include the opinion of an expert in regard to transcript as well in view of the march of science.
Referring the matter to the larger Bench, the Court, HELD: By the march of time, there is rapid development in the 125 field of forensic science and it has become imperative to match the said march of modern vistas of scientific knowl edge.
The question in the instant case whether the opinion of an expert in regard to type script would fall within the ambit of section 45 of the Evidence Act should, therefore, be examined in detail and decided by a Large Bench as the judgment in Hanumant 's case was rendered by a Bench of three Judges.
