Judges are expected to set aside their personal beliefs, biases, and external influences to maintain justice and preserve public confidence in the legal system; however, this is not consistently achieved.
At times, a judge's individual beliefs, biases, or external factors can inappropriately influence their decision-making, undermining the impartiality and fairness that are essential in legal proceedings. This phenomenon is referred to as judicial bias.
Judicial bias may manifest through favouritism, prejudice related to race, gender, socioeconomic status, political affiliations, or external pressures, such as public sentiment or financial motivations.
The existence of judicial bias in a legal system poses serious concerns that may challenge how the public perceives the legal system. Repeated instances of bias, or the appearance of it, damage the judiciary's reputation and undermine the belief that courts deliver fair and just rulings. This article examines what judicial bias is, its manifestations in courtrooms, and its impact on the administration of justice.

Judicial bias refers to any circumstance in which a judge shows favoritism or prejudice towards a party or issue in a legal case. Judicial bias can occur when a judge's personal beliefs or experiences influence their decision-making or when they have a relationship with one of the parties involved. This situation can prevent the judge from making decisions solely based on the facts and evidence presented in the case, potentially leading to unjust outcomes.
While judicial bias is a concern in all legal systems, it is essential for any party who perceives potential bias to address this issue at the earliest opportunity. They must provide a clear rationale linking their concerns to the appearance of actual bias and submit a formal request for the judge to recuse themselves. In the United States, judges are generally expected to disclose any matters that could create the appearance of bias, thereby enabling parties to make informed decisions about seeking recusal.
Additionally, a judge may elect to recuse themselves without disclosing specific details or the reasoning for their decision. However, the decision to recuse should be approached with careful consideration and made only with sufficient justification.
Judicial bias can take different forms depending on the circumstances surrounding the case. These include:
This refers to a situation where a judge is biased against or in favour of one of the parties to such an extent that the provision of facts and evidence would not alter their decision. Actual bias may be established when a judge has a personal relationship with one of the parties, a vested interest in the case, or a strong belief that favours one of the parties.
For example, in 2009, the U.S. Supreme Court delivered its verdict in Caperton v. Massey, which mandated the recusal of Judge Brent Benjamin. This ruling stemmed from the fact that one of the parties involved in the case had a considerable impact on the judge's selection by funding and steering the judge's election campaign while the case was imminent. Before reaching a decision, the court evaluated the relative size of the party's contributions against the total funds raised for the campaign, the overall expenditure during the election, and the evident influence that such contributions had on the election's result. This contribution was deemed sufficient to sway the judge's ruling in the case.
This refers to when there is a possibility of bias in a legal matter. Just like the name suggests, apprehended bias refers to circumstances where there is no clear bias, but a party feels that the judge may be impartial if allowed to continue with the case. Apprehended bias is established when a fair-minded lay observer can reasonably apprehend that the judge may not deal with the matter impartially.
For example, in 2016, the Pennsylvania Supreme Court delivered its verdict in Williams v. Pennsylvania, which highlighted that Judge Ronald's failure to recuse himself from the case raises concerns over impartiality, having been the District Attorney at the time of Williams' prosecution, and later the Chief Justice of the Pennsylvania Supreme Court that presided over Williams' appeal.
This refers to circumstances in which judges are influenced by subconscious feelings, attitudes, prejudices, and stereotypes during a legal proceeding. This bias occurs when a judge makes decisions that are motivated by subconscious feelings towards a race, religion, or specific gender.
Judicial bias can have a profound impact on court trials and their outcomes in several important ways. This section aims to outline some of these effects. First, bias may influence the motions, objections, or evidence that a judge permits during a proceeding. It can also affect the management of the case, including the overall pace of the trial. Such influences compromise the integrity of the trial and may hinder one party's ability to present their case comprehensively.
Additionally, judicial bias may result in the uneven assessment of evidence, which can create an undue advantage for one side over the other. It can also lead to the selective application of legal standards, such as interpreting ambiguous laws in a manner that reflects the judge's personal beliefs. This can ultimately contribute to wrongful convictions, dismissals, or inequitable sentencing.
Lastly, bias may be evident in sentencing practices, where penalties are imposed based on factors such as race, gender, or socioeconomic status rather than the severity of the offense or established legal guidelines.

Several systems exist in the United States to prevent and address judicial bias. These systems operate at various levels, from ethical guidelines to institutional oversight.
Federal and state judges adhere to established ethical codes, including the Code of Conduct for United States Judges. These codes are designed to ensure that judges maintain impartiality and avoid any appearance of conflict of interest while executing their duties.
Moreover,Chapter 28, Section 455of the United States Code mandates that judges recuse themselves from cases in which their impartiality could reasonably be questioned. In instances where a judge does not recuse themselves and continues to preside over a case, the judicial system allows parties to appeal the decisions to higher courts if they believe a ruling has been influenced by bias or legal error.
Lastly, both federal and state court systems provide mechanisms for filing complaints against judges in cases of alleged misconduct, including bias. Such complaints may initiate investigations and could result in disciplinary actions, which may range from reprimands to suspension or, in severe circumstances, the removal of the judge from office.
Proving judicial bias presents significant challenges due to various factors, including the inherent nature of bias and the legal system's commitment to safeguarding judicial independence. Bias can manifest as either explicit or implicit, meaning judges may not always be conscious of their biases. This complexity makes it difficult to differentiate between genuinely biased decisions and those that are legitimate. Furthermore, judges have discretion in interpreting laws, assessing evidence, and rendering rulings. Consequently, a decision perceived as biased by one party may be regarded as a valid application of discretion and legal reasoning by another.
Moreover, the legal framework assumes that judges act impartially, which places a considerable burden on the party claiming bias to provide compelling evidence that challenges this presumption. While this principle is essential for maintaining judicial independence, it complicates the ability to demonstrate bias without concrete proof. Establishing bias typically requires demonstrating a judge's intent or personal prejudice, which can be challenging to substantiate without clear behaviours, statements, or actions.
Despite these challenges, U.S. law obligates judges to recuse themselves from any proceedings in which their impartiality might reasonably be questioned. The objective criterion for assessing judicial bias is whether a reasonable person, considering all pertinent facts, would have legitimate grounds to question the judge's impartiality.
Judicial bias, whether actual or perceived, poses a significant threat to public confidence in the judicial system. Such bias often leads the public to question the equitable administration of justice. It raises concerns regarding the legitimacy of prior decisions, particularly when those rulings seem to align with a judge's political inclinations.
When external factors influence judges' decisions, judges may prioritize personal or external agendas over established legal principles. This situation can severely undermine the judiciary's standing as an independent and ethical institution.
Moreover, the lack of trust created by judicial bias can result in diminished respect for the court system, potentially leading individuals to disregard court rulings. In some cases, the public may resort to alternative methods for resolving legal issues, including civil disobedience or vigilante justice.
