The Legal Framework of Electronic Evidence in Vietnamese Criminal Procedure: From the Budapest Convention to Domestic Legislation
Summary: 1. Introduction. – 2. Methodology and Research Methods. – 3. Theoretical Framework on Electronic Evidence. – 3.1. Concept of Electronic Evidence. – 3.2. Fundamental Principles Governing Electronic Evidence. – 4. European and Vietnamese Legal Frameworks for Electronic Evidence. – 4.1. The European Regulatory Framework on Electronic Evidence. – 4.2. Shared Procedural Aspects of Investigating and Using Electronic Evidence. – 4.2.1. European Legal Framework. – 4.2.2. Vietnam’s Framework on Investigation of Electronic Evidence. – 5. Legal Gaps in Electronic Evidence Regulation in Vietnam Compared to the Budapest Convention. – 6. Conclusions.
Background: Electronic evidence constitutes a critical and sensitive subject addressed in international instruments on crime prevention, most notably the Budapest Convention on Cybercrime, and the Treaty on Cybercrime – UN (the Hanoi Convention), which was newly signed in Hanoi, Vietnam, in October 2025. The legal treatment of electronic evidence has emerged as one of the most vigorously debated topics within academic circles, particularly in discussions concerning the domestic incorporation of international treaty obligations.
Vietnam’s Criminal Procedure Code of 2015 represents a significant development by formally recognising electronic data as a legitimate form of evidence, equivalent in probative value to other traditional sources. As electronic evidence is becoming increasingly prevalent across a wide spectrum of criminal offences, this recognition is timely. However, with the rise of cybercrime, Vietnam’s current legal framework falls short of European standards, particularly in terms of conceptual clarity, procedural safeguards for the collection and evaluation of electronic evidence, protection of human rights, and adherence to adversarial principles.
Accordingly, this article aims to clarify the theoretical and legal framework for electronic evidence under European standards, compare it with Vietnam’s approach, and identify the theoretical and legal gaps that must be addressed—such as the need for clearer definitions, stronger procedural guarantees in evidence collection and assessment, human rights protections, and the reinforcement of adversarial principles.
Methods: To conduct a comparative analysis of electronic evidence within Vietnam’s criminal procedure law and international legal frameworks, the study draws on methodologies rooted in comparative legal studies. The analysis focuses on the comparative examination of international and domestic legal provisions concerning electronic evidence. Accordingly, the author makes extensive use of comparative legal methods, including normative comparison and functional comparison, to identify both similarities and differences between Vietnam’s regulations on sources of evidence in criminal procedure and those found in international instruments and the legal systems of other jurisdictions.
Results and conclusions: The article concludes that Vietnam’s legal provisions and practical implementation regarding electronic evidence must draw upon international experience in several key respects: the accurate conceptualisation of electronic evidence, the development of standardised procedures for its collection, and the refinement of legal mechanisms governing the duty to produce evidence, forensic examination, and the application of special investigative measures. Such reforms are essential to ensure the authenticity and legality of electronic evidence while safeguarding human rights within the criminal justice process.
Abstract
Background: Electronic evidence constitutes a critical and sensitive subject addressed in international instruments on crime prevention, most notably the Budapest Convention on Cybercrime, and the Treaty on Cybercrime – UN (the Hanoi Convention), which was newly signed in Hanoi, Vietnam, in October 2025. The legal treatment of electronic evidence has emerged as one of the most vigorously debated topics within academic circles, particularly in discussions concerning the domestic incorporation of international treaty obligations.
Vietnam’s Criminal Procedure Code of 2015 represents a significant development by formally recognising electronic data as a legitimate form of evidence, equivalent in probative value to other traditional sources. As electronic evidence is becoming increasingly prevalent across a wide spectrum of criminal offences, this recognition is timely. However, with the rise of cybercrime, Vietnam’s current legal framework falls short of European standards, particularly in terms of conceptual clarity, procedural safeguards for the collection and evaluation of electronic evidence, protection of human rights, and adherence to adversarial principles.
Accordingly, this article aims to clarify the theoretical and legal framework for electronic evidence under European standards, compare it with Vietnam’s approach, and identify the theoretical and legal gaps that must be addressed—such as the need for clearer definitions, stronger procedural guarantees in evidence collection and assessment, human rights protections, and the reinforcement of adversarial principles.
Methods: To conduct a comparative analysis of electronic evidence within Vietnam’s criminal procedure law and international legal frameworks, the study draws on methodologies rooted in comparative legal studies. The analysis focuses on the comparative examination of international and domestic legal provisions concerning electronic evidence. Accordingly, the author makes extensive use of comparative legal methods, including normative comparison and functional comparison, to identify both similarities and differences between Vietnam’s regulations on sources of evidence in criminal procedure and those found in international instruments and the legal systems of other jurisdictions.

ПРАВОВЕ РЕГУЛЮВАННЯ ЕЛЕКТРОННИХ ДОКАЗІВ У КРИМІНАЛЬНОМУ ПРОЦЕСІ ВʼЄТНАМУ: ВІД БУДАПЕШТСЬКОЇ КОНВЕНЦІЇ ДО НАЦІОНАЛЬНОГО ЗАКОНОДАВСТВА
Дінь Тхе Хунг
АНОТАЦІЯ
Вступ. Електронні докази є критично важливою та делікатною темою, що розглядається в міжнародних документах щодо запобігання злочинам, зокрема в Будапештській конвенції та Договорі Організації Об'єднаних Націй про кіберзлочинність (Ханойська конвенція), що був нещодавно підписаний у Ханої, В’єтнам, у жовтні 2025 року. Правове регулювання електронних доказів стало однією з найбільш обговорюваних тем в академічних колах, особливо в дискусіях щодо інкорпорації зобов'язань за міжнародними договорами всередині країни.
Кримінально-процесуальний кодекс В'єтнаму 2015 року зробив значний крок вперед, офіційно визнавши електронні дані як законну форму доказів, еквівалентну за доказовою силою іншим традиційним джерелам доказів. Оскільки електронні докази стають дедалі поширенішими в спектрі кримінальних правопорушень, це визнання є своєчасним. Однак, зі зростанням кіберзлочинності, чинне законодавство В'єтнаму виявляє значні обмеження порівняно з європейськими стандартами, особливо, що стосується концептуальної ясності, процесуальних гарантій збору та оцінки електронних доказів, захисту прав людини та забезпечення дотримання принципів змагальності.
Таким чином, ця стаття має на меті уточнити теоретичну та правову базу для електронних доказів згідно з європейськими стандартами, порівняти її з підходом В'єтнаму та визначити теоретичні та правові прогалини, які необхідно усунути, такі як: потреба в чіткіших визначеннях, сильніших процесуальних гарантіях збору та оцінки доказів, потреба в захисті прав людини та посиленні принципів змагальності.
Методи. Для проведення порівняльного аналізу електронних доказів у рамках кримінально-процесуального права В'єтнаму та міжнародно-правового регулювання автор статті використовує методологію, що ґрунтуються на порівняльно-правових дослідженнях. Аналіз зосереджений на порівняльному вивченні міжнародних та національних правових положень щодо електронних доказів. Відповідно, автор широко використовує порівняльно-правові методи, зокрема нормативне порівняння та функціональне порівняння, для виявлення як подібностей, так і відмінностей між нормативними актами В'єтнаму щодо джерел доказів у кримінальному процесі та тими, що містяться в міжнародних документах та правових системах інших юрисдикцій.
Результати та висновки. У статті було зроблено висновок, що правові положення В'єтнаму та їх практичне впровадження щодо електронних доказів повинні ґрунтуватися на міжнародному досвіді у кількох ключових аспектах: точна концептуалізація електронних доказів, розробка стандартизованих процедур їх збору та вдосконалення правових механізмів, що регулюють обов'язок подання доказів, судово-медичну експертизу та застосування спеціальних слідчих заходів. Такі реформи є важливими для забезпечення автентичності та законності електронних доказів, одночасно захищаючи права людини в рамках кримінального судочинства.
Ключові слова: кіберзлочинність, електронні докази, кримінальне провадження, електронні дані, законність електронних доказів, автентичність.
