The Malaysian High Court decision in Chuah Soo Peng v Ong Chin Wei is highly instructive for Indian courts interpreting the Bharatiya Sakshya Adhiniyam, 2023 (BSA), especially on how much proof is needed to link a WhatsApp voice note to an alleged sender. While not binding, its reasoning dovetails with India’s evolving jurisprudence on electronic records—from Anvar P.V. to Arjun Panditrao—and offers a practical, context‑sensitive approach that can be harmonised with sections 62–63 BSA.
Malaysian lesson: context, relationship and probabilities
In Chuah Soo Peng, the Sessions Court demanded technical confirmation (telco records, formal WhatsApp verification) before accepting that a WhatsApp voice note came from the defendant, even though the plaintiff and defendant were close friends and clients, and the plaintiff positively identified the defendant’s voice. The High Court corrected this, holding that in a civil case between well‑known parties, oral identification of the voice, combined with surrounding circumstances (subsequent meeting, contract clause drafted at defendant’s insistence), was sufficient on a “balance of probabilities” without mandatory telco proof.

The High Court still cautioned that where the purported sender is a stranger or rarely encountered person, courts may rightly insist on stronger proof, including evidence from telecom providers to link the number to the individual. This graded, fact‑sensitive approach—more demanding for strangers, more trusting when parties are familiar—speaks directly to Indian concerns about deepfakes, impersonation and manipulation of digital evidence.
Parallel structure under Bharatiya Sakshya Adhiniyam, 2023
Under the BSA, electronic and digital records are expressly recognised as “documents” and “evidence,” continuing and modernising the earlier framework of sections 65A–65B of the Indian Evidence Act. Sections 62 and 63 now govern admissibility of electronic records, broadly carrying forward the logic of former section 65B: computer output/WhatsApp data is admissible if statutory conditions and certification (now under section 63) are met, ensuring authenticity and reliability.
Indian commentary and early case‑law under BSA confirm that WhatsApp chats and other messages are treated as electronic records; they require either production of the original device (primary evidence) or a properly certified copy satisfying section 63(2)–(4). Recent discussion has also emphasised that self‑certification by the person in lawful control of the device can be a valid mode of compliance, echoing the “statutory declaration” route seen in Chuah Soo Peng.
Admissibility vs attribution: where the Malaysian case fits
Indian law now clearly separates two stages:
Admissibility: compliance with BSA sections 62–63 (successor to 65A–65B) and the IT Act, as clarified by Anvar P.V. and Arjun Panditrao.
Attribution/weight: whether the record can be safely read as coming from a particular person, and with what evidentiary value.
Chuah Soo Peng mainly speaks to the second stage: once the WhatsApp voice note is properly brought on record (in that case via section 90A Evidence Act certificate and producing the phone), how much more is needed to say “this voice is yours.” Indian courts face the same question with WhatsApp chats and voice messages: after a section 63 BSA certificate or primary‑device production, can authorship be decided by:
Testimony of the recipient who is familiar with the sender’s voice or style of communication.
Prior and subsequent messages showing a consistent pattern of dealing.
Corroborative conduct (meetings, contracts, payments) aligning with what the message says.
The Malaysian High Court’s answer—yes, in a close‑relationship case this can be enough on a preponderance of probabilities—provides a persuasive model for Indian trial courts applying the BSA in civil and even criminal contexts (subject to the higher standard of proof in the latter).
Flexibility within the strict BSA framework
Indian Supreme Court decisions such as Anvar P.V. v. P.K. Basheer and Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal stressed that electronic evidence is admissible only with proper certification, but they also recognised that if the original device is produced and proved by the owner, the rigid certificate requirement softens. BSA sections 62–63 and current commentary explicitly carry forward this balance: strict structure for admissibility, flexibility in how that structure is satisfied, and then a contextual evaluation of weight.
Here, Chuah Soo Peng is a useful reminder that once statutory admissibility thresholds are met, courts should not over‑insist on expensive or impractical technical confirmation in every case, especially where:
The parties are in a pre‑existing, close relationship (friends, family, regular business partners, lawyer–client).
The witness has strong familiarity with the voice and communication habits of the alleged sender.
The surrounding transaction (like a loan or contract) and documents objectively fit the contents of the voice note.
For Indian courts under BSA, this supports a two‑tiered approach:
Stricter demands (forensic reports, telco data, platform logs) in stranger cases, high‑value fraud, or where fabrication is specifically alleged.
More reliance on human familiarity and circumstantial corroboration in close‑relationship disputes, after section 63 compliance, much like the Malaysian High Court did.
Practical implications for Indian practitioners
For Indian lawyers and judges dealing with WhatsApp voice notes under the BSA:
Ensure formal compliance with BSA sections 62–63 (or production of the original device) to cross the admissibility hurdle, in line with Arjun Panditrao and the new scheme.
Distinguish clearly between admissibility of the record and proof of authorship of the voice; the latter can legitimately rest on lay voice recognition and contextual evidence, as accepted in Chuah Soo Peng.
Use the Malaysian judgment as persuasive authority to argue that in cases involving friends, relatives or known associates, Indian courts need not mechanically insist on telco‑level proof to attribute a WhatsApp voice note, provided the probabilities, relationship and corroboration strongly support authorship.
In short, Chuah Soo Peng v Ong Chin Wei offers a pragmatic, relationship‑sensitive template for Indian courts applying the Bharatiya Sakshya Adhiniyam: respect the statutory rigour on electronic records, but decide “whose voice it is” by looking at human familiarity and real‑world probabilities, not just technical certificates.
