Concerns Regarding DNA Law
Background
The Department of Biotechnology released, in 29 April 2012, a working draft of a proposed Human DNA Profiling Bill, 2012 ("DBT Bill") for public comments. The draft reveals an effort to (i) permit the collection of human blood, tissue and other samples for the purpose of creating DNA profiles, (ii) license private laboratories that create and store the profiles, (iii) store the DNA samples and profiles in various large databanks in a number of indices, and (iv) permit the use of the completed DNA profiles in scientific research and law enforcement. The regulation of human DNA profiling is of significant importance to the efficacy of law enforcement and the criminal justice system and correspondingly has a deep impact on the freedoms of ordinary citizens from profiling and monitoring. Below, we highlight five important concerns to bear in mind before drafting and implementing DNA legislation.
Primary Issues
Purpose of DNA Profiling
DNA profiling serves two broad purposes – (i) forensic – to establish unique identity of a person in the criminal justice system; and, (ii) research – to understand human genetics and its contribution to anthropology, biology and other sciences. These two purposes have very different approaches to DNA profiling and the issues and concerns attendant on them vary accordingly. Forensic DNA profiling is undertaken to afford either party in a criminal trial a better possibility of adducing corroborative evidence to prosecute, or to defend, an alleged offence. DNA, like fingerprints, is a biometric estimation of the individuality of a person. By itself, in the same manner that fingerprint evidence is only proof of the presence of a person at a particular place and not proof of the commission of a crime, DNA is merely corroborative evidence and cannot, on its own strength, result in a conviction or acquittal of an offence. Therefore, DNA and fingerprints, and the process by which they are collected and used as evidence, should be broadly similar.
Procedural Integrity
Forensic DNA profiling results from biological source material that is usually collected from crime scenes or forcibly from offenders and convicts. Biological source material found at a crime scene is very rarely non-contaminated and the procedure by which it is collected and its integrity ensured is of primary legislative importance. To avoid the danger of contaminated crime scene evidence being introduced in the criminal justice system to pervert the course of justice, it is crucial to ensure that DNA is collected only from intact human cells and not from compromised genetic material. Therefore, if the biological source material found at a crime scene does not contain at least one intact human cell, the whole of the biological source material should be destroyed to prevent the possibility of compromised genetic material being collected to yield inconclusive results. Adherence to this basic principle will obviate the possibility of partial matches of DNA profiles and the resulting controversy and confusion that ensues.
Conditions of Collection
In India, the taking of fingerprints is chiefly governed by the Identification of Prisoners Act, 1920 ("Prisoners Act") and section 73 of the Indian Evidence Act, 1872 ("Evidence Act"). The Prisoners Act permits the forcible taking of fingerprints from convicts and suspects in certain conditions. The Evidence Act, in addition, permits courts to require the taking of fingerprints for the forensic purpose of establishing unique identity in a criminal trial. No
provisions exist for consensual taking of fingerprints, presumably because of the danger of self-incrimination and general privacy concerns. Since, as discussed earlier, fingerprints and DNA are biometric measurements that should be treated equally to the extent possible, the conditions for the collection of DNA should be similar to those for the taking of fingerprints.Accordingly, there should be no legal provisions that enable other kinds of collection, including from volunteers and innocent people.
Retention of DNA
As a general rule applicable in India, the retention of biometric measurements must be supported by a clear purpose that is legitimate, judicially sanctioned and transparent. The Prisoners Act, which permits the forcible taking of fingerprints from convicts, also mandates the destruction of these fingerprints when the person is acquitted or discharged. The indefinite collection of biometric measurements of people is dangerous, susceptible to abuse and invasive of civil rights. Therefore, once lawfully collected from crime scenes and offenders, their DNA profiles must be retained in strictly controlled databases with highly restricted access for the forensic purpose of law enforcement only. DNA should not be held in databases that allow non-forensic use. Further, the indices within these databases should be watertight and exclusive of each other.
DNA Laboratories
The process by which DNA profiles are created from biological source material is of critical importance. Because of the evidentiary value of DNA profiles, the laboratories in which these profiles are created must be properly licensed, professionally managed and manned by competent and impartial personnel. Therefore, the process by which DNA laboratories are licensed and permitted to operate is significant.
