Science Beyond Dispute: Why the Law Must Surrender to Evidence -By Yovita Arie Mangesti

Corruption today no longer consists of handwritten notes passed in secret between persons meeting in dim, clandestine rooms. It takes the form of an email, and is concealed in digital ledgers, funneled through algorithmic transfers scattered via complex financial networks With the result that scientific evidence is still in many jurisdictions including Indonesia, the weak sister to testimony in courts of law or written documents. This hesitancy is no longer tenable. If justice serves truth, then the demands of evidencen particularly scientific evidence must be complied with by law. Indonesia’s Criminal Procedure Code (KUHAP 2025), as codified in Article 235, places eight kinds of evidence on an equal footing: witness testimony, expert opinion, documents, judges observation, electronic evidence, the defendant’s statement and everything that can be used for the purpose of proof during a court trial as long as it is obtained lawfully.. However, digital forensics, DNA analysis of products from financial audits, and complicated algorithms for analyzing metadata are not seen as something that merits its own separate category. They are merely included within the expert witness testimony section or documentary evidence. This structural omission creates confusion in legal dogma as well as a lack of uniformity in the practice of trying corruption cases. The progress towards digital transactions and technological instruments in corruption cases requires a more robust evidentiary framework. Emails, encrypted chats, banking transaction logs, security video recordings, and forensic accounting reports are not only crutches on the front but also central contrivances for implementation and detection of corruption. To treat these as mere appendices is to misunderstand the architecture of modern crime. Science affords something which human testimony frequently cannot: methodological reliability and replicability. A digital forensic extraction can be tested again. A DNA profile may be reconfirmed. A financial audit is subject to scrutiny afresh. Scientific discoveries are not error proof, but they are built on falsifiability and peer review. By contrast, the testimony of witnesses is open to distortion from memory, to bias, to suppression and enticement, to the twisting of psychological influences.

People know well the epistemic conflict that exists between law and science: as illustrated in the inter case considerations where a judge accepts expert testimony and yet rejects similar evidence in his own case. Law has to be final; science develops. Courts must take decisions although scientific knowledge remains undoubtedly probabilistic. However, this conflict does not further our aim of dismantling scientific evidence. On the contrary, it requires stronger evidentiary standards methodological reliability testing, chain of custody verification, laboratory accreditation, and judicial gatekeeping.Courts face inconsistency without clear standards. For example, one judge may accept a digital transcript but another may object because the original metadata has been lost. Such discrepancies undermine legal certainty and equality before the law. Justice cannot depend on the technological literacy of individual judges.Problems are not simply technical; rather, they have constitutional implications. Corruption constitutes an extraordinary crime because it strikes at a people’s democracy, their trust and their economic stability. Extraordinary crimes need evidence of an extraordinary standard. When corruption cases fail because procedure is disputed over electronic records or audit findings, people see not fairness but weakness.However, giving way to evidence does not mean giving way to uncontrolled scientific authority. Scientific evidence itself must be supervised. The chain of custody must be intact. Laboratories must be accredited. Experts should be independent and impartial. Raw data needs to be accessible to the defense for examination. The rules of judicial oversight operate as a filter to stop unreliable methods.In many advanced legal systems, courts apply reliability tests before accepting scientific evidence. Judges determine if the method is testable, whether it has a recognized error rate, and whether it is generally accepted in the scientific community. Indonesia’s legal system can no longer rely on the juxtaposition of fragments of statutes to govern evidence; instead, a whole new evidentiary doctrine needs to be instituted.

Scientific evidence, as an independent form of facts, even when recognised from a human rights perspective not weakens the standard for holding that total failure outside such category may be grounds for widespred miscarriages in due process. Driven by clear rules, followup checkd prevent defendants from being unjustly punished and the secret false testimony brought out by unproven interpretations of fact is also good for society.

The real problem, philosophically speaking, is about ontology. If scientific evidence really does exist then what reason does it have being invisible as a normative force? But asking whether we can observe trees being chopped down and then count them later – on pure scientific evidence-for which method is infallible would render modern witness testimony more adapted to mental hospitals.

It is impossible for any trial system that puts empirical reality outside of its own consciousness band to remain in touch with the truth. The law can not simply be aesthetic externals when offenses develop new technologies.

What is more, the public’s confidence in the fair play of its own country’s judicial organs depends more and more on their handling ability with digital and forensic evidence. An era that will soon see “no civilization if no science” is taking shape, courts must set their legitimacy publicly and stepper by spiking arguments based not just on basic principles but strong scientific evidence itself. Decisions made from such a time-honored perspective are relatively free of being discredited by popular misconceptions.

To give way to evidence certainly does not mean weakening the law: if anything, it only strengthens it. Law has to be the holder of expectations, but it also must admit that this century’s way of discerning truth is not separable from science. The reform measure required is straightforward:

1. Define scientific evidence as an independent admissible category.

2. Set Reliability and Methodology Standards.

3. Chain of custody protocols need to be made mandatory.

4. Accreditation requirements for Forensic Laboratories should be put in place.

5. Judicial Gatekeeping power not so much over any stage of the prosecution or appeal process as behind which evidence an accused may plead as a last resort.

Equal opportunities for both sides to review evidence, an evaluation by professionals on what are called independent advice procedures and this needs to be subject of popular debate.

Corruption is nimble. Justice must be quicker.

If criminal procedure’s mission is to discover what really happened, then science isn’t at the periphery, it’s a path there. The law shouldn’t ignore evidence. It should accord it, manage it, and affirm faith in inspectors of truth.

For in the end, justice does not yield to power.

It only stands up for truth.
