LEGAL DISPUTES CONCERNING DNA-BASED PATERNITY TESTING AND PARENTAGE DETERMINATION

1. INTRODUCTION

DNA-based paternity disputes arise when the biological relationship between an alleged father and a child is questioned in matters involving legitimacy, maintenance, inheritance, succession, guardianship, custody and matrimonial proceedings. DNA testing provides powerful scientific evidence for determining biological parentage. However, its use raises significant legal questions concerning privacy, dignity, the presumption of legitimacy, the rights of children and the evidentiary authority of scientific testing.

In India, paternity disputes are governed by the Bharatiya Sakshya Adhiniyam, 2023, applicable family and personal laws, constitutional protections and judicial precedents. Courts must balance the need to discover biological truth against the protection of family relationships and individual rights.

2. LEGAL FRAMEWORK GOVERNING DNA-BASED PATERNITY DISPUTES

A. Bharatiya Sakshya Adhiniyam, 2023

The Bharatiya Sakshya Adhiniyam, 2023, provides the evidentiary framework applicable to judicial proceedings.

Section 116 continues the statutory presumption of legitimacy for a child born during a valid marriage or within 280 days after its dissolution, provided the mother remains unmarried, unless it is established that the parties had no access to each other at a time when the child could have been conceived.

This provision is particularly important because DNA evidence cannot automatically override the statutory presumption without satisfying the applicable legal requirements.

B. Hindu Marriage Act, 1955

Section 112 of the former Indian Evidence Act, 1872, was the corresponding provision governing legitimacy. Its substance is now reflected in Section 116 of the Bharatiya Sakshya Adhiniyam.

Section 13 provides grounds for divorce, while Section 24 concerns interim maintenance and litigation expenses. Paternity disputes may arise in matrimonial proceedings involving allegations of adultery or disputed parentage.

C. Family Courts Act, 1984

Section 7 gives Family Courts jurisdiction over proceedings concerning matrimonial status, legitimacy, maintenance, guardianship and custody. Section 14 permits Family Courts to receive reports, statements and other material that may assist them in resolving disputes.

D. Constitutional protection

Article 21 protects privacy, dignity and personal autonomy. Article 14 requires fairness and non-arbitrary judicial treatment. Article 39(f) supports the protection and development of children.

3. MAJOR LEGAL ISSUES IN DNA-BASED PATERNITY DISPUTES

A. Presumption of legitimacy

A child born during a valid marriage enjoys a statutory presumption of legitimacy. Courts generally require strong evidence to rebut this presumption.

B. Consent and compulsory DNA testing

Courts must consider whether ordering a DNA examination is necessary, proportionate and justified by the circumstances. A DNA test should not be ordered merely because one party makes an unsupported allegation.

C. Privacy and dignity

DNA samples contain highly sensitive genetic information. Their collection and examination must respect privacy, bodily autonomy and applicable legal safeguards.

D. Inheritance and succession disputes

DNA evidence may become relevant when determining biological relationships in succession, inheritance and property proceedings. However, biological parentage and legal parentage are not necessarily identical.

E. Child welfare and identity

Courts must consider the child's emotional security, dignity, family relationships and long-term interests. Establishing biological truth should not become an instrument of unnecessary humiliation or discrimination.

4. IMPORTANT JUDICIAL DECISIONS

The following judgments establish the principal rules governing DNA testing, paternity presumptions and biological parentage.

1. Goutam Kundu v. State of West Bengal (1993), Supreme Court of India

The Supreme Court held that courts should not routinely order blood tests in paternity disputes. The applicant must establish a strong prima facie case, and the court must consider the consequences of such testing.

Legal principle: DNA or blood testing cannot be ordered as a matter of course merely to investigate allegations concerning parentage.

2. Sharda v. Dharmpal (2003), Supreme Court of India

The Supreme Court recognised that matrimonial courts possess power to direct medical examinations where necessary for resolving disputes. It also explained that refusal to comply with a lawful examination order may permit an adverse inference, depending on the circumstances.

Legal principle: Medical examination may be ordered when necessary, but judicial discretion must be exercised carefully.

3. Banarsi Dass v. Teeku Dutta (2005), Supreme Court of India

The Court emphasised the importance of the statutory presumption of legitimacy and cautioned against ordering DNA testing without sufficient justification.

Legal principle: The law protects the legitimacy of children and discourages unnecessary scientific investigations into parentage.

4. Bhabani Prasad Jena v. Convenor Secretary, Orissa State Commission for Women (2010), Supreme Court of India

The Supreme Court held that DNA testing should be directed only when a strong prima facie case exists and the court considers the examination necessary for a just decision.

Legal principle: Scientific evidence must be balanced against privacy, dignity and the interests of the child.

5. Nandlal Wasudeo Badwaik v. Lata Nandlal Badwaik (2014), Supreme Court of India

The Court considered a DNA report that contradicted the presumption arising under Section 112 of the Indian Evidence Act. It held that reliable scientific evidence could prevail in the particular circumstances of the case.

Legal principle: The Court recognised the importance of reliable DNA evidence when determining biological parentage, while the statutory presumption remains an important legal consideration.

6. Dipanwita Roy v. Ronobroto Roy (2015), Supreme Court of India

The Supreme Court permitted DNA testing in matrimonial proceedings involving a specific allegation of adultery. It observed that refusal to undergo testing could result in an adverse inference under the circumstances.

Legal principle: DNA examination may be justified where it is directly relevant to resolving a specific matrimonial dispute.

7. Ashok Kumar v. Raj Gupta (2022), Supreme Court of India

The Supreme Court reiterated that DNA testing should not be ordered routinely in civil disputes and must be justified by the requirements of the case.

Legal principle: Courts must balance the evidentiary value of DNA testing against privacy, dignity and the consequences for family relationships.

5. EVIDENTIARY VALUE AND LIMITATIONS OF DNA TESTING

DNA testing is scientifically powerful, but its legal value depends on reliability and proper evidentiary procedures.

Important considerations include:

Proper identification of the persons providing biological samples.

Documented collection and preservation procedures.

Maintenance of an appropriate chain of custody.

Use of scientifically validated laboratory methods.

Examination by qualified forensic experts.

Disclosure of relevant laboratory findings and limitations.

Opportunity for parties to challenge the reliability of the report.

A DNA report must be evaluated in the context of the complete evidence. A biological relationship does not automatically determine every legal question concerning custody, adoption, maintenance or inheritance.

6. LEGAL REMEDIES AND PRACTICAL COMPLIANCE

A party involved in a paternity dispute may seek an appropriate judicial direction for DNA examination before a competent court. The application should explain the relevance of testing, the disputed issue and why ordinary evidence is insufficient.

Courts should consider whether the test is necessary, whether less intrusive evidence is available and whether the consequences for the child are proportionate.

Forensic laboratories should maintain confidentiality, reliable testing procedures, sample traceability and accurate reporting. Parties should avoid publicly disclosing genetic reports or using them to harass or stigmatise children and family members.

7. CONCLUSION

DNA-based paternity disputes involve a complex relationship between scientific truth, statutory presumptions, family stability and constitutional rights. Indian courts have consistently recognised that DNA testing is an important evidentiary instrument but should not be ordered automatically. Decisions such as Goutam Kundu, Bhabani Prasad Jena, Nandlal Wasudeo Badwaik and Dipanwita Roy establish the principal judicial approach. Ultimately, courts must ensure that biological evidence assists the administration of justice without unnecessarily violating privacy, dignity or the welfare of children.
