Is It Safe to Entrust Trials to AI? — The Real Reasons Why Even Simple Cases Are Considered Risky

Should AI Not Even Judge "Simple Cases"?

An article published on Phys.org on April 7, 2026, argues that we should be cautious about using generative AI even in "simple trials." The argument is straightforward. AI can process documents quickly, cheaply, and in a consistent format. This makes it appealing in an era when court workloads are overwhelming. However, a judgment is not merely about arranging sentences or listing past cases. It involves the human activity of listening to the parties involved, understanding the circumstances, and making decisions between law and fairness. The original article highlights the dangers of introducing machines into the core of the judiciary, citing weaknesses of generative AI such as hallucinations, discriminatory outputs, and opacity.

The gravity of this issue is underscored by the fact that AI use in judicial settings has already begun worldwide. The UK judiciary updated its AI usage guidance in October 2025, stating that AI use must not compromise "the integrity of judicial operations" and "the rule of law." The guidance warns of the risks of biased training data, hallucinations, and the input of confidential information, emphasizing that the final responsibility for AI-generated content lies with the judges. This implies that while supplementary use is possible, the responsibility itself cannot be separated from humans.

Looking at actual implementations, countries are not aiming for "AI judges" per se, but rather systems that are closer to supplementary tools. In Taiwan, a system has been trialed where AI generates draft judgments for relatively standardized criminal cases like drunk driving and fraud assistance, but the authority for fact-finding, legal application, and sentencing remains with the judges. Estonia is often cited as an advanced example of "AI judges," but the country's judicial and digital administration authorities have clarified that they are not developing AI judges to replace human judges in small claims or general procedures. According to an Oxford University report, Estonia has a semi-automated system for issuing payment orders for small claims up to 8,000 euros, but human oversight remains. While the topic may seem advanced, the reality is not "fully automated trials."

Nevertheless, the original article's author argues that even "simple cases" are risky, and this point is significant. After all, what is deemed simple is decided by humans. Pensions, benefits, damages, seemingly minor criminal cases—while these may appear to be routine processes from the system's perspective, they often represent serious issues that can affect the lives, reputations, and futures of the parties involved. Moreover, the court is not just a device for producing a single correct answer. The sense that "I was heard" and that the circumstances were understood by humans is itself what supports the legitimacy of the judiciary. The original article argues that AI lacks the ability to understand human elements such as pain, regret, vulnerability, and reliability, making it unsuitable for the judge's seat.

Furthermore, the promise of efficiency is not so simple at present. Reuters reported in January 2026 that since the generative AI boom, false or incorrect citations have been entering court submissions, resulting in dozens of cases where lawyers have been sanctioned. In February, a federal judge in Kansas fined lawyers a total of $12,000 for submitting nonexistent citations and case law created by AI without verification. Sanctions continued in March over false case law related to AI. In court, what's important is not "writing something that seems plausible" but "what is truly correct." If this foundation crumbles, the time supposedly saved by AI will ultimately be lost in verification, correction, retrials, and appeals.

On the other hand, the pressure on the ground is indeed pushing for AI adoption. Reuters reported in January that U.S. judges have formed a collaborative organization to share the benefits and pitfalls of AI. There, discussions are taking place about how AI can shorten the time for legal research and drafting, while also introducing new dangers such as hallucinations and deepfake evidence. The Washington Post also reported in April that over 60% of the 112 surveyed U.S. federal judges use AI in some form, with 22% using it regularly. The judiciary has already entered the AI era. However, what is advancing is not "automation of judgments" but "supplementary use with the premise that humans bear the final responsibility."

 

Looking at reactions on social media and forums, the strong emotions surrounding this issue are evident. In the AI-related community on Reddit, negative voices are prominent, such as "It's possible to teach logical judgment, but difficult to teach empathy and humility" and "Isn't this just offloading work to AI?" Some posts even sarcastically suggest a world where "your online history determines a high probability of guilt," indicating that concerns about AI judges are not just technical but also about the fear of "humans being reduced to data."

However, there are also supporters and those who conditionally accept AI. In another Reddit discussion, arguments were made that "human judges and juries are also influenced by emotions, hunger, bias, and appearances" and that "the comparison should be whether it's better than the current human-centered system, not whether it's perfect." Additionally, some support a "collaborative model" that combines AI as an incorruptible foundation with humans as a compass for mercy and context. While reactions on social media seem polarized, they are actually converging towards "supplementary use + human responsibility" rather than "complete replacement." It is reasonable to view these social media reactions as indicative of discussion trends rather than as a public opinion survey.

Ultimately, the core of this debate is not about performance. No matter how much accuracy improves, the question of what a trial means in a democratic society remains. The courtroom is not merely a device for efficiently handling cases. When the state judges an individual, the very promise that humans bear responsibility for that judgment supports trust in the judiciary. Therefore, while AI will increasingly excel in peripheral tasks such as document organization, case law research, summarization, and drafting assistance, if we delegate the final line of "judging people," the judiciary might become more convenient at the cost of its legitimacy. The original article warns precisely about this point. Speed is one condition of justice, but it is not justice itself.
