Evidentiary Value of Blood Stain Report and DNA Report under Indian Judiciary

The application of science and scientific technicalities to law for to find a solution to the problems and crimes are termed as Forensic science. Normally these techniques are regularly used by Scientific experts, examiners, crime investigators etc….for crime investigation, and examination of suspected documents, digital files, finger prints, blood stains and other evidences. On the basis of such examination, that expert makes scientific reports which have a greater importance under Indian judicial system. Sec 45 of Indian Evidence Act appreciated and accepts. All forensic methods for individualization—fingerprints, dental impressions, striations on bullets, hair and fiber comparisons, voice spectrograms, neutron-activation analysis, blood-grouping and serum-protein and enzyme typing, as well as DNA profiling—demand an ability to match samples with reasonable accuracy with respect to characteristics that can help to differentiate one source from another. If such evidence is to be useful in court, scientifically acceptable procedures must permit the reliable measurement and comparison of physical features. Likewise, a scientific basis must exist for concluding that properly performed comparisons can distinguish possible sources.
