Algorithmic bias threatens legal fairness in AI era

Artificial intelligence is rapidly transforming the way decisions are made in public and private sectors, from predictive policing and credit scoring to healthcare diagnostics and job recruitment. However, according to a new study titled “Algorithmic Bias as a Core Legal Dilemma in the Age of Artificial Intelligence: Conceptual Basis and the Current State of Regulation”, published in Laws (Volume 14, Issue 3, June 2025), algorithmic bias has emerged as a fundamental legal and ethical problem that current regulations are failing to address.

The study dissects the conceptual underpinnings of algorithmic bias and argues that its growing presence in AI systems undermines fundamental principles of justice, equality, and legal predictability. Unlike traditional human bias, which can be attributed and challenged through legal norms, algorithmic bias is often embedded deep within data training sets and machine learning architectures. As a result, the outcomes of biased algorithms can be both invisible and systematic, affecting individuals based on gender, ethnicity, age, or socioeconomic status without transparent justification.

The authors highlight that algorithmic systems frequently reproduce and amplify existing inequalities rather than eliminate them. In many instances, historical data reflects the discriminatory patterns of the past. When machine learning models are trained on such data without proper intervention, they institutionalize past prejudices into future decisions. The result is an automated form of discrimination that lacks clear legal accountability under current European and international frameworks.

What is missing from the current legal framework?

The study provides a comparative analysis of how different legal jurisdictions, particularly within the European Union, are attempting to deal with algorithmic bias. It concludes that while several legal instruments touch on elements of the problem, such as the EU Charter of Fundamental Rights, anti-discrimination directives, and the General Data Protection Regulation (GDPR), none are sufficiently equipped to directly or comprehensively address the structural challenges posed by biased algorithms.

The GDPR, for instance, offers limited protections under Article 22 regarding automated decision-making. However, the study points out that this protection is narrow in scope, often inapplicable where a “human-in-the-loop” is nominally included, even if the human’s oversight is superficial. Additionally, transparency obligations under the GDPR often fall short when applied to AI models whose operations are technically complex or proprietary in nature.

The authors also examine the proposed EU AI Act, which categorizes high-risk AI applications and mandates certain compliance standards. Yet the paper argues that even this forward-looking regulation does not go far enough in defining or detecting algorithmic bias. There is currently no uniform legal definition of algorithmic bias across EU institutions, and national regulatory bodies lack the technical capacity to assess AI systems for discriminatory impacts. This absence of clarity leaves both individuals and public authorities in a weak position to seek remedies or enforce ethical compliance.

A key concern raised in the research is that algorithmic bias often escapes detection due to a lack of transparency and explainability. Many AI systems are built on “black box” models that offer minimal insight into how outputs are generated. Even when discrimination is suspected, proving it in legal terms becomes nearly impossible under existing evidentiary standards. The study emphasizes that this lack of procedural clarity constitutes a threat to rule-of-law principles and judicial fairness.

What are the proposed legal reforms and policy solutions?

In response to these challenges, the study offers a framework for reform aimed at embedding algorithmic accountability into both national and supranational legal systems. It advocates for the establishment of a harmonized legal definition of algorithmic bias that encompasses direct, indirect, and systemic discrimination caused by machine learning systems. This definition would form the foundation for enforceable anti-bias obligations in AI deployment.

The authors recommend a multi-tiered approach to regulation that includes pre-deployment bias audits, real-time monitoring tools, and mandatory post-deployment impact assessments. These tools would be overseen by independent supervisory bodies with technical expertise, empowered to suspend or sanction non-compliant AI systems.

Another key proposal is the introduction of a reverse burden of proof in algorithmic discrimination cases. This would shift the obligation onto organizations deploying AI to demonstrate that their systems are fair and non-discriminatory. Such a shift would significantly reduce barriers for individuals seeking redress and bring algorithmic systems in line with broader principles of administrative accountability.

The paper also calls for public sector leadership in setting standards. Government agencies and courts using AI should adhere to strict procurement guidelines requiring fairness-by-design and explainability. Public interest algorithms, such as those used in welfare or criminal justice systems, should be subject to democratic oversight, including input from civil society, ethicists, and affected communities.

On a broader policy level, the study urges the integration of AI ethics into legal education and public administration. Without legal professionals trained in AI systems and their societal implications, enforcement of new regulations will remain inconsistent and reactive. The paper stresses that legal systems must evolve in tandem with technological advancements to uphold fundamental rights.
