Living-Donor Kidney Transplant: Maternity Need Not Be Proved by DNA Where Documentary Evidence Establishes Relationship on a Preponderance of Probabilities

1. Introduction

In RITA CHAURASIYA v. THE STATE OF TAMIL NADU (Madras High Court, 21-05-2026), the petitioners—Rita Chaurasiya (mother/donor) and B. Rohit Kumar Chaurasiya (son/recipient)— sought judicial intervention after the Authorization Committee (2nd respondent) refused permission for a living kidney donation. The proposed transplant was to be undertaken at M/s.Apollo Speciality Hospital (3rd respondent), Chennai, due to the recipient’s emergent renal condition.

The core issue was narrow but consequential: whether the Authorization Committee could deny approval by insisting that the mother-son relationship was “not established” (in effect pressuring for higher proof such as DNA testing), despite available documentary materials.

2. Summary of the Judgment

  • The Court found the Committee’s refusal casual and unjustified when the donor claimed to be the recipient’s biological mother.
  • On the materials produced (including the recipient’s birth certificate and both parties’ Aadhaar/PAN details), the Court held that the relationship was established on a preponderance of probabilities.
  • The Court ruled that the mother should not be compelled to undergo a DNA test to prove maternity in these circumstances.
  • The impugned proceedings dated 17.04.2026 were set aside, and the Authorization Committee was directed to grant permission forthwith, with urgency emphasized (preferably by the next week).

3. Analysis

3.1 Precedents Cited

(a) Order dated 30.05.2024 in W.P.No.13918 of 2024 etc batch

The judgment relies on an earlier Madras High Court order (authored by the same Judge) that examined how Authorization Committees should assess donor-recipient relationships and motives—especially where allegations of commercial dealings are a concern. While that order addressed broader scenarios (including non-near relatives), it laid down important guardrails against arbitrariness:

  • Intangible motives cannot be reduced to crude proxies: The earlier order criticized reliance on the “length of association” as a decisive factor, noting that “love and affection are intangible sentiments” and cannot be measured by time.
  • Do not demand proof of a negative: Applicants cannot be overburdened to “prove” absence of commercial consideration beyond reasonable scrutiny.
  • Reject only on definite material: Permission “ought not to be withheld or rejected” unless there is “definite material” of financial dealing.
  • Donor welfare is part of the Committee’s function: The order also emphasized the Committee’s obligation to ensure donor needs are met, referencing statutory concepts (including the exclusion of certain defrayed expenditures from “payment”) and suggesting structured support mechanisms.

In the present case, these principles indirectly reinforced the Court’s intolerance of a template rejection lacking adequate engagement with the record— all the more so because this was not even a “non-near relative” scenario.

(b) Sonia Ajit Vayklip Vs. Hospital Committee, Lilavati Hospital (2012 SCC Online Bom 64)

The extracted passage from the 2024 order discusses the Bombay High Court’s view that where donor and recipient are “near relatives” and the case does not fall under the exceptions in Section 9(4) of the Act, the Authorization Committee has no power to make further enquiry about the motive, because the commercial element is presumed absent.

Although the present judgment does not independently re-apply Section 9(4) analysis, the citation operates as a normative baseline: where “near relative” status exists, the Committee’s role is not to invent obstacles. Here, the Committee’s error preceded motive enquiry—it questioned the relationship itself despite credible documentation.

(c) Order dated 31.05.2024 in W.P.No.13642 of 2024

The Court notes its earlier holding that even where a non-relative states donation is altruistic and not commercial, that statement “cannot be challenged”. In the present matter, the donor is a mother—making the Committee’s skepticism even less defensible. The reference strengthens the judgment’s theme: authorization cannot be converted into adversarial disbelief without reason.

3.2 Legal Reasoning

The Court’s reasoning is built on three interlocking steps:

  1. Assessment of the record (documentary corroboration): The Court noted the presence of the recipient’s birth certificate and the parties’ Aadhaar and PAN, showing consistent family linkage through the named spouse/father (Ratan Lal Chaurasia).
  2. Standard of proof—preponderance of probabilities: The Court explicitly applied a civil standard (“preponderance of probabilities”) to conclude that the recipient is the biological son of the donor. This is significant: the Court treated the authorization exercise as an administrative decision requiring rational satisfaction on credible materials, not forensic certainty in every case.
  3. Proportionality in evidentiary demands (DNA test not mandatory): Having found the relationship probable on the record, the Court held that the mother should not be called upon to undergo DNA testing. Implicitly, DNA testing was viewed as an exceptional measure—appropriate only where genuine doubt persists after reasonable scrutiny, not as a routine hurdle.

On this basis, the Court found the Committee’s stand arbitrary and set it aside, issuing a time-sensitive direction to ensure the patient’s urgent needs were met.

3.3 Impact

  • Administrative discipline for Authorization Committees: The judgment signals that Committees must make evidence-based determinations and cannot reject applications perfunctorily, especially in near-relative cases.
  • DNA testing as an exception, not the rule: By holding that a mother need not undergo DNA testing where documents establish maternity on a balance of probabilities, the Court reduces delay and prevents escalation of proof standards beyond what fairness and urgency warrant.
  • Urgency-sensitive judicial review: The Court’s directive “forthwith” (and preferably by the next week) reinforces that transplantation decisions are time-critical and administrative indecision can have irreversible consequences.
  • Future litigation posture: Applicants can rely on this decision to argue that authentic public documents (birth certificate, IDs, consistent family particulars) should ordinarily suffice to establish near-relative status, shifting the burden back to the State/Committee to justify any further intrusive verification.

4. Complex Concepts Simplified

Writ of certiorarified mandamus
A combined constitutional remedy where the court (i) quashes an unlawful administrative decision (certiorari) and (ii) directs the authority to do what it is legally bound to do (mandamus).
Authorization Committee
A statutory/administrative body that scrutinizes living organ donation proposals to prevent coercion and commercial trafficking, and to ensure legal compliance.
Near relative
A legally recognized close familial relationship (such as parent-child). Near-relative status typically reduces suspicion of commercial dealing and narrows the scope of enquiry.
Preponderance of probabilities
The civil standard of proof meaning “more likely than not.” The Court used it to decide that the mother-son relationship was sufficiently established on record.
Section 9(4) of the Act (as referenced in the extracted precedent)
Mentioned in the earlier order’s discussion of when additional enquiry into motive may (or may not) be permissible. The citation underscores that motive enquiries are constrained where near-relative status is established.
Rule 17 (as referenced in the extracted precedent)
Referred to as providing the scrutiny mechanism for applications and allowing clarifications/verification in case of doubt—supporting a measured, non-arbitrary process.
DNA test insistence
Treated here as a disproportionate demand when ordinary documentary evidence already supports maternity; the Court effectively places it in the “only if real doubt remains” category.

5. Conclusion

This decision crystallizes a practical and humane rule for transplant authorization: where near-relative relationship (maternity) is supported by credible documents, the Authorization Committee must accept it on a preponderance of probabilities and cannot insist on DNA testing as a routine requirement. By quashing a casual rejection and directing immediate approval, the Madras High Court reinforced that anti-trafficking safeguards must operate with reasoned scrutiny, proportional evidentiary demands, and urgency-sensitive administration—particularly when a patient’s life and health depend on timely transplantation.
