I. INTRODUCTION Crimes are committed in very sophisticated form these days. It is highly technical as well. The investigating agency can be benefited from the use of modern scientific developments to commensurate with the diversified and perplexed modus operandi of offences. The court of law can also take help of the expertise of science in this matter. One of the branches of biological science working to help in this regard is neuroscience. Neuroscience has various inclinations towards law. The neuroscience is such inclined towards the law that this new discipline is termed as Neurolaw. It is having the potential to address various complex questions of the motivation of crime and shall assist law in realising its objectives. However, in Salvi judgement of the Supreme Court of India, one such technique, Brain Mapping, was not allowed considering various factors. The apprehension of the Courts to allow the Brain Mapping, however, is affected by the recent development of neuroscience. The scope of the paper is to put forth the recent development after the decision of the court than towards shedding lights on the normative aspect of the decisions of the court, which is discussed incidentally.

Neurolaw: The Concept Neuroscience is one of the most emerging sciences with fast new horizons of research. Neurolaw, the interdisciplinary study of neuroscience and law, establishes a relationship of Brain with Law. The finds more relevance in the jurisprudence to expand its scope. The expansion of Law and Neuroscience is a matter of Neurolaw. The study of Neurolaw asks a more comprehensive and accurate approach to the legal phenomena considering the importance of Brain, that are associated with for the formulation of reasoning and discerning morality, by an accused. Neurolaw also tries to show the existence of the Mens Rea, the mental element for the commission of an offence, of an offender, which is a sine qua non for his conviction in the court of law. The scientific approach to the Mens Rea shall make delivery system fairer. It is believed that Neurolaw would generate a better juridical system. The achievement of neuroscience can radically change the legal provisions, process and customs.

Neurolaw: Right to Silence, and Brain Mapping Silence is a non-communicative aspect of a human being. A person tries to wear a calm composure in silence. To reduce oneself into silence a person avoids communication to lower his mental activity. External concepts and ideas come through communication put a strain on the mind of a person. Silence helps a person to remain his being and promotes personal strength of conviction and regaining confidence. Right to silence is a right of human being human. Mental privacy is an extension of the right to silence stemming from the cardinal right against self-incrimination. Mental privacy is also an aspect of the right to privacy. The realisation of the right to privacy is the promotion of right against self-incrimination and also of the right to life. Silence is also cherished in jurisprudence. A non-coercive law respects constituents of the silence of a human being as a human right. Silence in the normative aspect has certain consequences. In its origin, the "right to silence" has origin in

Another facet of this right is to cast the burden on the state to prove a case before the court of law, beyond a reasonable doubt. From the right to silence right to be presumed to be innocent until his guilt is proven is asserted. And most important is the right of an accused against self-incrimination, means he cannot be compelled to incriminate himself or give against himself before the court of law. The accused has the right to remain silent as mostly during the investigation of a crime, the mind is conditioned by the extraneous process, making the statement involuntary. This last right has a broad sweep. The accused is entitled to remain silent during an investigation of an offence against him, and any statement which is obtained by use of coercive method violating his right to silence cannot be allowed to be adduced as evidence before the court of law. A statement that amounts to a confession made before an investigating authority, police, is not admissible before the court of law, even if the statement of facts are relevant to the case. So much so that, confessional statement further is protected even if it is not made before the police but made in the custody of a police officer in Indian . And the judicial pronouncements in India on the interpretation of custody have been broadened to save the accused from harsher interrogations. However, in reality, the investigating agency is working in such extreme pressure and such strenuous situation that to deal on the one hand hardened criminal to dreaded terrorists and on the other hand to maintain safety and security of the common citizen, they resort to an easy way of extracting information from a suspect by unleashing vicious custodial interrogation techniques violating those sacrosanct rights and constitutional values. To maintain a balance poses a challenge to the state.

The challenge lies how the facts residing in the mind of a human being can be divined out without violating the right to silence and the human right of a person. Towards this objective various branches of science are working including the emerging discipline of Neurolaw. This shall help the investigating agency to respect the and investigate with scientific temper. Considering the importance of Brain, which we may associate with for the formulation of Reasoning and also Mens Rea or guilty mind, a sine qua non for convicting an accused person, in the field of , the relationship between Neuroscience and Law, gives scope for the interdisciplinary study of Neurolaw and begs for an inclusive and appropriate approach to the phenomena and events of operation of law. Neurolaw, the interdisciplinary study of neuroscience and law, establishes a relationship of Brain with Law. Neurolaw is a novel attempt to find assimilation between neuroscience, law and the brain, taking into accounts the latest findings in the discipline of neuroscience. Neurolaw as a discipline tries to make the evidence more accurate and enhances the weight of evidence before a court of law and shall result in making justice fairer. It is, in fact, the explorations of the effects of discoveries in the domain of neuroscience on the law. It also indicates an exploration and expansion of the scope of jurisprudence and to encourage precocious comprehension of the legal issues thereof. The expansion of the horizon of normative science and Neuroscience is the matter of Neurolaw. For an accurate understanding of the legal issues, neuroscientific data might be of significance. It is believed that Neurolaw would generate a better formulation of law and judicial decisions for a fairer judicial system. The achievement of neuroscience could radically change the legal provisions, process and customs.

The neuroscience technique can be and are used to understand the mind of a person. Brain images are developed in neuroscience it to study and understand the mind. A higher form of neuro-imaging is also popularly known as Brain Mapping. The brain is mapped to learn the Memory and Learning of a person. Neuro- imaging in Brain Mapping in is often buttressed by the findings of additional imaging or non-imaging data or analysis. These can be mapped projecting the behaviour of a subject onto the respective brain regions. In 2013, the Society of Brain Mapping and Therapeutics (SBMT) defined "as the study of the anatomy and function of the brain and spinal cord through the use of imaging, immunohistochemistry, molecular & optogenetics, stem cell and cellular biology, engineering, and nanotech1. The techniques of mapping of brain Mapping are continuously maturing and are depending upon development and refinement of image retrieval, representation, analysis, and interpretation techniques. It is believed that, through the use of these techniques, facts are safely diving out of the mind of a subject or accused of a crime, which otherwise he is reluctant to give, and which often is obtained by the investigating authority in a most unpopular way by using proscribed third- degree method violating the right to silence and other fundamental rights of a person.

Technique of Neurolaw For an accurate understanding of the legal issues, neuroscientific data might be of significance. Lots of cases with diversified legal context bearing relationship with neuro-scientific evidence are increasingly reaching to the court of law in different parts of the world. Though the number of such cases is very few and far between in India, however, the astute of India would insulate themselves from introducing facts by way of evidence bearing on neuro-scientific developments. In this regard, the neuroscience concepts tap the effect of law and its

ISSN- 2394-5125 VOL 7, ISSUE 19, 2020 consequences that are linked to the neurological issues. Therefore, understanding the neuroscience dimension which has implications with the law is inevitable. The understanding of neuroscience dimension having implication with the law has increased due to the mapping technology used by neuro-scientist to understand the aspects of the functioning of the brain and its motivation. map the brain through the use of various techniques to under brain functioning, a various region of the mind associated with various normative behaviour. The mapping of the brain is fast developing. A wide range of technology and methods are used to understand various co-relates of brains and concepts like knowledge, intention, negligence, recklessness, purpose and other motivation of the mind of a person. The could able to show that the nervous system is frequency oriented as opposed to amplitude oriented.2 A kind of Brain Mapping is Late Positive Complex or P3 or P300. It is a component of averaged brain potentials. In this test, no questions are asked to the accused. He is made to sit in evoked potential recording machine and is shown objects relating to the crime scene or is made to hear sounds pertaining to crime site. The sensors from his head pick the event-related potentials in the form of Brain Mapping only if the person has been at the site of crime. The accuracy of Brain Mapping is almost 100%.3 Like noted earlier, the frequency of the Brain can be trapped through brain-mapping technology. "Technically explaining, Brain Mapping involves confrontation with a stimulus of special significance with an electric signal known as P300 emitted from an individual's brain, beginning approximately 300 million milliseconds after the confrontation. Since it is based on EEG signals and graphs, the system does not require the subject to speak at all and he in a way continues to exercise his right to keep silent. The suspect wears a special hair band with an electronic sensor that measures the EEG from several locations on the scalp".4 The suspect sees the screen on the computer or maybe administered to view directly any pictures, objects or materials etc.

Understanding of Neurolaw Technique in Selvi Case In Smt. Selvi & Oth vs. State of Karnataka and Another5, the popular Brain Mapping Technique was called into question among other methods of investigation. The court first tried to understand the Brain Mapping Test. Citing from Andre A Moensses, Brain Fingerprinting court understood "Brain Electrical Activation Profile test is also known as the `P300 Waves test'. It is a process of detecting whether an individual is familiar with certain information by way of measuring activity in the brain that is triggered by exposure to selected stimuli. This test consists of examining and measuring `event-related potentials' (ERP) i.e. electrical waveforms emitted by the brain after it has absorbed an external event. An ERP measurement is the recognition of specific patterns of electrical brain activity in a subject that are indicative of certain cognitive mental activities that occur when a person is exposed to a stimulus in the form of an image or a concept expressed in words. The measurement of the cognitive brain activity allows the examiner to ascertain whether the subject recognised stimuli to which he/she was exposed”.6

Further, the Court enumerated "By the late 19th century it had been established that the brain functioned by emitting electrical impulses and the technology to measure them was developed in the form of the electroencephalograph (EEG) which is now commonly used in the medical field. Brain wave patterns observed through an EEG scan are fairly crude and may reflect a variety of unrelated brain activity functions. It was only with the development of computers that it became possible to sort out specific wave components on an EEG and identify the correlation between the waves and specific stimuli. The P300 wave is one such component that was discovered by Dr Samuel Sutton in 1965. It is a specific event-related brain potential (ERP) which is triggered when information relating to a specific event is recognised by the brain as being significant or surprising”.7

The Court further quoted "Dr Lawrence Farwell has argued that the P300 wave component is not an isolated sensory brain effect but it is part of a longer response that continues to take place after the initial P300 stimulus has occurred. This extended response bears a correlation with the cognitive processing that takes place slightly beyond the P300 wave and continues in the range of 300-800 milliseconds after the exposure to the stimulus. This extended brain wave component has been named as the MERMER (Memory- and-Encoding- Related-Multifaceted Electroencephalographic Response) effect”.8

Further, the Literature of Laboratory Procedure Manual - Brain Electrical Activation Profile, Directorate of Forensic Science, Ministry of Home Affairs, Government of India threw light on the concept of P 300 Test. "The P300 waves test is conducted by attaching electrodes to the scalp of the subject, which measure the emission of the said wave components. The test needs to be conducted in an insulated and air-conditioned room to prevent distortions arising out of weather conditions. This test also requires effective collaboration between the investigators and the examiner, most importantly for designing the stimuli which are called `probes'. Ascertaining the subject's familiarity with the `probes' can help in detecting deception or to gather useful information. The test subject is exposed to auditory or visual stimuli (words, sounds, pictures, videos) that are relevant to the facts being investigated alongside other irrelevant words and pictures. Such stimuli can

5963

JOURNAL OF CRITICAL REVIEWS

ISSN- 2394-5125 VOL 7, ISSUE 19, 2020 be broadly classified as material `probes' and neutral `probes'. The underlying theory is that in the case of guilty suspects, the exposure to the material probes will lead to the emission of P300 wave components which will be duly recorded by the instruments. By examining the records of these wave components the examiner can make inferences about the individual's familiarity with the information related to the crime”9.

The concerns of the Supreme Court of India in Selvi Case The court was concerned on the right of mental privacy of the accused or the subject of the test. It echoed the similar concern of Michael S. Pardo, "Even though these (brain mapping tests)are non- invasive techniques the concern is not so much with the manner in which they are conducted but the consequences for the individuals who undergo the same. The use of techniques such as `Brain Fingerprinting' and `FMRI-based Lie-Detection' raise numerous concerns such as those of protecting mental privacy and the harms that may arise from inferences made about the subject's truthfulness or familiarity with the facts of a crime”. 10 Also another distinguished author noted in the same area, Henry T. Greely11, “There are several other concerns with the development of these `mind-reading' technologies especially those relating to the privacy of individuals”.

One of the key criteria of Daubert Test12 to approve the fact of the scientific method in the court of law, that is, the methodology should have attracted widespread acceptance within its scientific community, the court found that "Dr Lawrence Farwell's `Brain Fingerprinting' technique has attracted considerable publicity but has not been the subject of any rigorous independent study. Even if the `probes' are prepared by an examiner who is thoroughly familiar with all aspects of the facts being investigated, there is always a chance that a subject may have had prior exposure to the material probes. In case of such prior exposure, even if the subject is found to be familiar with the probes, the same will be meaningless in the overall context of the investigation. For example, in the aftermath of crimes that receive considerable media-attention the subject can be exposed to the test stimuli in many ways. Such exposure could occur by way of reading about the crime in newspapers or magazines, watching television, listening to the radio or by word of mouth. A possibility of prior exposure to the stimuli may also arise if the investigators unintentionally reveal crucial facts about the crime to the subject before conducting the test. The subject could also be familiar with the content of the material probes for several other ”13.

The court was also apprehensive about the test that "there is no conclusive guidance about the actual nature of the subject's involvement in the crime being investigated. For instance, a bystander who witnessed a murder or robbery could potentially be implicated as an accused if the test reveals that the said person was familiar with the information related to the same”.14

The Ratios of the Apex Court The court had the opportunity of looking into the of polygraph and BEAP test. The court stated " Even though the actual process of undergoing a polygraph examination or a BEAP test is not the same as that of making an oral or written statement, the consequences are similar. By making inferences from the results of these tests, the examiner is able to derive knowledge from the subject's mind which otherwise would not have become available to the investigators. These two tests are different from medical examination and the analysis of bodily substances such as blood, semen and hair samples since the test subject's physiological responses are directly correlated to mental faculties. Through lie-detection or gauging a subject's familiarity with the stimuli, personal knowledge is conveyed in respect of a relevant fact. It is also significant that unlike the case of documents, the investigators cannot possibly have any prior knowledge of the test subject's thoughts and memories, either in the actual or constructive sense. Therefore, even if a highly-strained analogy were to be made between the results obtained from the impugned tests and the production of documents, the weight of leans towards restrictions on the extraction of `personal knowledge' through such means. In any case, the compulsory administration of the impugned tests impedes the subject's right to choose between remaining silent and offering substantive information. The requirement of a `positive volitional act' becomes irrelevant since the subject is compelled to convey personal knowledge irrespective of his/her own volition”15. Finding favour from the Ronald J. Allen and M. Kristin Mace16 whose theory narrated that "the right against self- incrimination is meant to protect an individual in a situation where the State places reliance on the `substantive results of cognition", the court held that BEAP test shall violate the right to mental privacy, which is a cardinal principle of the right to silence stemming from the rule against testimonial compulsion or right against self- incrimination, U/A 20(3) of of India. The court also, with elaborate foregone reasoning considered that BEAP test should not be read into medical examination under the code17.

Considering the effect of 161(2) of Code of Criminal Procedure, 1973,(Cr.P.C), which bars the statement of the accused to be signed, the court found some more circumstances which though not barred u/s161 (2) can be barred utilising Art 21 of the Constitution of India. The court stated "a person who refuses to undergo

5964

ISSN- 2394-5125 VOL 7, ISSUE 19, 2020 these tests could face the risk of custodial violence, increased police surveillance or harassment thereafter. Even a person who is compelled to undergo these tests could face such adverse consequences on account of the contents of the test results if they heighten the investigators' suspicions. Each of these consequences, though condemnable, falls short of the requisite standard of `exposure to criminal charges and penalties' that have been enumerated in Section 161(2) of the Cr.P.C, 1973." The court also reached the same effect of right to silence taking into account Art 21, rather than Article 20(3) of Constitution of India.

The court not only not allowed BEAP test to conduct in the criminal case but also cases where there is no penal consequence on the ground that it denied the principle of a fair . The court noted, "Even though Article 20(3) will not be applicable in such circumstances, reliance can be placed on Article 21 if such non- penal consequences amount to a violation of `personal liberty' as contemplated under the Constitution".18

Neurolaw advancements post Selvi case. The Neuroscience has made advancement in Brain Mapping technique. Another developing kind of Brain- Mapping is BEOS. BEOS is the short-expression for Brain Electrical Oscillations Signature Profiling. This is a technology to interrogate a suspect or even a witness with hardly any stress put to him. The person undergoes a non-invasive technique and does not ask any response from him rather he to listen to various probing facts given to him by the system. This test removes the apprehension of the Supreme Court more particularly false implication of a suspect or accused as because he had exposure to the test-stimuli prior to by learning the facts from media reports or intimation of facts to him by the investigating agency s or his association to the crime as a bystander.

It is used to identify remembrance. "The BEOS system was developed for examining a suspect with least amount of stress of being tested as the procedure does not require any response from the subject, except to listen to the probes presented by the system. The verbal statements presented by the system cue the remembrance of an original experience provided the person has had it. Otherwise, there will be no remembrance cued by the statements, even if the person knows about the episode”.19 This he states as EK, Experimental Knowledge as opposed to Knowledge, simply. To understand the meaning of the statement, awareness of a knife is different from the use of the knife. Mertens R and Polich J. state that "larger areas of the brain take part in the process of remembrance of autobiographical episodes in comparison with that of recognition of familiar external entities”.20 So, a person, if he is having knowledge of experience-based, can be distinguished from awareness of familiarities. "The results of BEOS are obtained in form of electrical activity from the brain related to probes....the test expects the subject to remain silent and only listen to a narrative presented as short verbal statements (probes) in sequence, subject need not give any oral response to the stimulus, but the brain waves indicate that the brain has some information in regard to these items”.21

Anjan Patel sums up his two hypotheses "this research first HO is = There will be no significant difference in the neuro-psychological assessment of BEOS result like; primary processing, experiential knowledge, encoding, emotional response, activation suppression. This HO is rejected because in different criteria of BEOS automated analysis result shows percentile variation in primary processing, experiential knowledge, encoding, emotional response, activation suppression. Second H/O= BEOS is based on the principles of neuro-psychology which is a baseless principle. This HO is rejected because EEG cap attached to a person and case-related probes were presented during this procedure then suspect were aware in relevant, general neutral probes and neutral probes. All four person's neurological and psychological criteria like: primary processing, experiential knowledge, encoding, emotional response, activation suppression, were counted together so it shows above 95.00 % all four persons were neuro-psychologically aware during the BEOS test”.22 Polich J. further throws lights on remembrance as, "remembrance of autobiographical episodes or experiences often constitutes a re-experiencing of the past episode, which may be pleasant or distressing and therefore, it may involve total or near total retrieval of all the aspects of sensory-motor information from the memory”.23

II. CONCLUSION Neuro-scientific development is constantly expanding horizon to understanding various mental aspect as well as an association of neuron to the behaviour of a person. The above findings suggest there is potential for the neuroscience to affect change on the jurisprudence. It can make a positive contribution to the legal discipline. The decision of the Supreme Court of India in Smt Selvi & Oth v State of Karnataka and Another Case is affected by this new development in neuroscience, which is a domain of Neurolaw to study.

III. CONFLICT OF INTEREST The authors declare no conflict of interest in this study
