1️⃣ Definition

Concurring opinion refers to an opinion in which a justice in a collective judicial body such as the Constitutional Court or Supreme Court agrees with the majority opinion (ruling and reasoning) but presents additional views or arguments. In simple terms, it means agreeing with the final conclusion but expressing separate thoughts on the reasoning or approach.

A concurring opinion does not affect the ruling (conclusion) of a decision but adds diversity to the logic and interpretation of the judgment. This is distinct from a dissenting opinion (which opposes the conclusion).

💡 Why is it important?

• Concurring opinions can form the foundation for legal development and influence future rulings.
• They present diverse legal perspectives that add depth to the judgment's reasoning.
• They show various viewpoints on social issues, contributing to public discourse.

2️⃣ Meaning and Role of Concurring Opinions

📕 Legal Significance of Concurring Opinions

• Concurring opinions complement and enrich the majority opinion. While supporting the conclusion and core logic of the majority opinion, concurring opinions provide additional arguments or analyses from different angles. This has the effect of broadening the scope of legal judgment and strengthening its logic. They may address issues not covered by the majority opinion or present different approaches to the same issues, thereby enhancing the completeness of the judgment. They may also express views on related legal issues that are not directly applicable to the current case but could serve as references for similar future cases.

• Concurring opinions can serve as stepping stones for changes in precedent. While respecting the current majority opinion, concurring opinions can suggest new legal directions that may become the foundation for future changes in precedent. Concurring opinions containing new interpretations that reflect social changes or evolving values may gradually gain consensus over time and eventually develop into a new majority opinion. This process allows for gradual and stable development of legal principles rather than abrupt changes. Particularly in cases involving sensitive constitutional values or interpretations of fundamental rights, concurring opinions can serve as a compass pointing to the future direction of legal development.

📕 Types and Characteristics of Concurring Opinions

• Concurring opinions appear in various types. Concurring opinions can be categorized into several types based on their content and approach. First, logic-reinforcing concurrences strengthen or refine the logic of the majority opinion. They reach the same conclusion as the majority opinion but present clearer or more persuasive arguments. Second, scope-limiting concurrences agree with the principle of the majority opinion but clarify its scope or conditions of application. They emphasize that the majority opinion's principle should be applied restrictively in certain situations. Third, future-oriented concurrences suggest how the principles should be applied to similar future cases beyond the current case. They play a role in indicating the direction of legal development.

• Concurring opinions hold special significance in impeachment trials. In historically important cases such as presidential impeachment, concurring opinions carry even greater significance. First, they provide diverse interpretations of constitutional issues. They present various perspectives on constitutional issues such as separation of powers, the constitutional duties of the president, and the gravity of impeachment grounds. Second, they have value as historical records. The varied constitutional considerations and decision-making processes of the justices are recorded through concurring opinions in historical decisions. Third, they contribute to ensuring political neutrality. By showing that each justice reached the conclusion through their own independent constitutional interpretation, they strengthen the political neutrality and legal validity of the decision.

📕 Constitutional Value of Concurring Opinions

• Concurring opinions are an expression of judicial democracy. Concurring opinions hold constitutional value beyond simply adding legal opinions. First, they reflect diversity and a culture of discussion within the judiciary. By recognizing diversity in reasons and approaches even when conclusions are the same, they demonstrate that democratic discussion and diverse views are respected within the judiciary. Second, they reveal the independence and conscience of justices. They function as a channel through which each justice can express their independent legal judgment while conforming to the collective decision. Third, they serve as a communication channel between law and society. By publicly disclosing various aspects of the legal judgment process, they promote communication between the judiciary and civil society.

• Concurring opinions contribute to legal debate and academic development. Concurring opinions have a significant impact on legal research and practice. First, they serve as starting points for legal research. New legal claims contained in concurring opinions attract academic interest and promote follow-up research. Second, they are important teaching materials in law schools. They have educational value in teaching various methods of legal analysis for the same case. Third, they influence lawyers' future litigation strategies. Even if they are minority or concurring opinions now, they may become majority opinions in the future, so legal practitioners refer to them when developing litigation strategies. In this way, concurring opinions promote diversity in legal discourse and contribute to the development of legal scholarship.

These concurring opinions mainly addressed the evidential value and application of rules of evidence, criteria for determining the gravity of impeachment grounds, and the scope of the president's constitutional duties. A particularly notable issue was how the hearsay rule in criminal procedure law (a principle limiting the evidentiary value of secondhand evidence) should be applied in impeachment trials. Some justices argued that the hearsay rule should be applied more flexibly considering the special nature of impeachment trials, while others argued that it should be strictly applied to guarantee the president's right to defense.

• The concurring opinions contributed to the development of legal principles in impeachment trials. The concurring opinions in this decision contributed significantly to the development of legal principles for future impeachment trials, beyond simply expressing views on the current case.

First, it demonstrates respect for minority opinions. Even in final judgments decided by majority vote, the diverse opinions of individual justices are officially recorded and respected.

4️⃣ Related Terminology

🔎 Hearsay Rule

• The hearsay rule is a principle that limits the evidentiary value of secondhand evidence.
• The hearsay rule is a principle in criminal procedure law that, in principle, prohibits the use of hearsay evidence—content heard from others rather than directly experienced—as evidence. For example, "C's testimony that A told B that he was the perpetrator" is hearsay evidence and is, in principle, limited in its evidentiary capacity. The hearsay rule exists because, first, statements not directly experienced are highly susceptible to distortion, and second, it is difficult to verify the truthfulness without cross-examining the original declarant in court. However, exceptions are made when the circumstances of the statement ensure reliability (such as confessions with contemporaneity or statements made in an excited state) or when there are special circumstances that make it difficult to bring the original declarant to court. In the impeachment trial, how strictly to apply this hearsay rule became an important issue.

🔎 Unanimous Decision

• A unanimous decision is a state where all members agree with the same opinion.
• A unanimous decision refers to a state where all participants in a meeting, discussion, or vote agree on the same opinion or conclusion. In collective judicial bodies such as the Constitutional Court or Supreme Court, it refers to cases where all justices agree with the same conclusion (ruling). In President Yoon Seok-yeol's impeachment trial, all eight justices unanimously voted in favor of removal, resulting in a unanimous decision. Unanimous decisions have greater legitimacy and persuasiveness than majority decisions and tend to have higher social acceptability. However, unanimity does not mean that all justices reached the conclusion with identical reasoning or logic; they may have arrived at the same conclusion with different logic or perspectives. These differences are expressed as concurring opinions. Therefore, even in unanimous decisions, various concurring opinions can exist, and these serve as important materials showing different legal aspects of the decision.

🔎 Right of Defense

• The right of defense is a constitutional right to respond to legal actions against oneself.
• The right of defense refers to the constitutional right of a party to defend themselves in procedures that may result in adverse legal decisions, such as criminal trials or impeachment trials. It is a fundamental right derived from the principle of due process and is a core element of the right to a fair trial. The main contents of the right of defense include: first, the right to know the content of the charges; second, the right to legal assistance; third, the right to review and refute evidence; fourth, the right to cross-examine witnesses; and fifth, the right to present favorable evidence and arguments. In impeachment trials as well, the respondent's (president's) right of defense must be importantly guaranteed, and the protection of the right of defense is an important consideration in the application of rules of evidence. Justices who argued for strict application of the hearsay rule in concurring opinions presented the protection of the respondent's right of defense as a main argument.

5️⃣ Frequently Asked Questions (FAQ)

Q: What is the difference between a concurring opinion and a dissenting opinion?

A: Concurring opinions and dissenting opinions are both individual opinions of justices in collective judicial decisions, but they have important differences. First, they differ in their attitude toward the conclusion. Concurring opinions agree with the conclusion (ruling) of the majority opinion, while dissenting opinions oppose the conclusion itself. For example, in an impeachment trial, a concurring opinion agrees with the "removal" conclusion but differs in reasoning or approach, whereas a dissenting opinion opposes the "removal" itself. Second, they differ in their impact on the result of the judgment. Concurring opinions do not affect the result, but dissenting opinions could change the result if they shift from minority to majority depending on the composition of the justices. Third, they differ in legal significance. Concurring opinions play a role in complementing and enriching the majority opinion, while dissenting opinions present criticism and alternative interpretations of the majority opinion. Fourth, they differ in their role in future changes in precedent. Dissenting opinions are direct challenges to current precedent and can become direct grounds for changing precedent in the future, while concurring opinions influence by developing legal principles within the framework of current precedent.

Q: Why are concurring opinions important in impeachment trials?

A: There are several reasons why concurring opinions are particularly important in significant constitutional decisions such as impeachment trials. First, they have value as historical records. By recording in detail what constitutional concerns and legal judgments the justices made in historical events such as impeachment, they leave important constitutional reference materials for future generations. Second, they strengthen political neutrality. By showing that various legal approaches are possible in politically sensitive cases, they demonstrate that the decision was based on various constitutional value judgments rather than a specific political position. Third, they contribute to social integration. Since impeachment can cause social division, showing through concurring opinions that various constitutional values and perspectives are respected helps increase the social acceptability of the decision. Fourth, they suggest criteria for judging similar future cases. Since impeachment trials are rare special constitutional trials, presenting judgment criteria for various issues through concurring opinions serves as an important reference for similar future cases. Fifth, they strengthen institutional trust in the Constitutional Court. By showing that justices have engaged in deep consideration and diverse approaches to complex constitutional issues, they increase public trust in the Constitutional Court as an institution.

Q: How do concurring opinions influence subsequent rulings?

A: Concurring opinions have no legal binding force but influence subsequent rulings in various ways. First, they become seeds for legal development. Though currently concurring opinions, they may develop into majority opinions in the future as legal principles and social perceptions change. In fact, many important changes in precedent in the past originated from concurring or dissenting opinions in previous judgments. Second, they serve as reference materials for similar cases. In new cases with similar issues, courts review and reference concurring opinions from previous judgments. Third, they influence lower courts. Concurring opinions from the Supreme Court or Constitutional Court become important reference materials for lower courts when judging similar cases. Fourth, they influence the legislature. Legal issues or institutional improvements raised in concurring opinions may become occasions for the legislature to consider legal amendments. Fifth, they stimulate discussion in the legal community and academia. New legal issues contained in concurring opinions generate active discussion in the legal community and academia, contributing to legal development. Thus, while concurring opinions do not affect the immediate result of a judgment, they have an important influence on the gradual development of law and the direction of future judgments.

Q: How can ordinary citizens understand and use concurring opinions?

A: There are several ways ordinary citizens can understand and use concurring opinions. First, they can be used as tools to enhance legal understanding. Concurring opinions show various legal approaches that arrive at the same conclusion, helping to understand complex legal issues from multiple angles. Second, they can be used as reference materials for social discussion. Referring to the logic of concurring opinions in discussions about constitutional values or social issues enables deeper discussions. Third, they can provide ideas for legal responses. By examining concurring opinions in cases similar to one's own legal problems, one can gain ideas about new legal approaches. Fourth, they can be used as criteria for evaluating the transparency and credibility of the judiciary. Judgments with diverse concurring opinions are evidence that sufficient discussion and deliberation took place within the court. Fifth, they can be used as materials for civic education. Concurring opinions, especially those on constitutional values and fundamental rights, can be good materials for civic education or legal education. To understand concurring opinions, it is helpful to refer to judgments provided on the websites of the Constitutional Court or Supreme Court, or to find expert commentary through legal media and academic materials.
