Japanese civil procedure, while heavily reliant on the Principle of Party Presentation (Benron Shugi - 弁論主義) where litigants bear the primary responsibility for presenting their case, is not a system where the court remains entirely passive. The Japanese Code of Civil Procedure (CCP) grants courts the "power to clarify" (shakumei ken - 釈明権) under Article 149. This power allows judges to ask questions and prompt parties to provide further factual assertions or evidence. More significantly, case law and legal doctrine have evolved this power into a "duty to clarify" (shakumei gimu - 釈明義務) in certain circumstances, and more recently, a "duty to point out legal perspectives" (hōteki kanten shiteki gimu - 法的観点指摘義務) has gained prominence. Understanding when and how a Japanese court might intervene is crucial for litigants to navigate the procedural landscape effectively.

The Court's Power to Clarify (Shakumei Ken)

Article 149, Paragraph 1 of the CCP states: "The presiding judge may, on the date for oral argument or on any other date, ask questions of parties or prompt them to produce evidence with regard to factual or legal matters, in order to clarify the matters related to the suit." Paragraph 2 allows associate judges to do the same after notifying the presiding judge.

The term "clarification" (shakumei - 釈明) in this context refers to the court's actions aimed at elucidating the "matters related to the suit" (訴訟関係 - soshō kankei), which essentially means the overall picture of the case, its contours, and the core disputed points needing resolution. It can also refer to the responsive assertions or evidence provided by a party following such a prompt.

The fundamental purpose of this power, as articulated by the Supreme Court (e.g., Supreme Court, June 11, 1970, Minshu Vol. 24, No. 6, p. 516), is to:

  1. Correct any unreasonableness that might arise from a purely formalistic application of the Principle of Party Presentation.
  2. Clarify the relationship of the matters in the suit.
  3. Ascertain the substantive truth as much as possible.
  4. Thereby achieve a genuine and just resolution of the dispute between the parties.

Without such a power, a rigid adherence to Benron Shugi could lead to outcomes where the party that "should" win according to substantive justice loses due to technical deficiencies in their presentation of facts or evidence—a scenario often described as turning litigation into a mere "sport." The court's power to clarify reflects its public role in ensuring fair and just trials.

While the court can prompt, parties are generally not compelled to respond in a specific way; their failure to adequately clarify their position might lead to adverse inferences, but the ultimate responsibility for presenting their case still rests with them, thus formally upholding Benron Shugi.

The scope of this power explicitly extends to both factual and legal matters. The 1970 Supreme Court judgment affirmed that if a different legal construction from the one presented by the plaintiff could lead to the plaintiff's success and a more fundamental resolution of the dispute, and if the plaintiff's failure to adopt such a construction appears to be due to a clear misunderstanding or carelessness, the court is permitted to exercise its power to clarify, even if it involves suggesting a different cause of action.

From Power to Duty: The Duty to Clarify (Shakumei Gimu)

Although Article 149 CCP frames clarification as a judicial power, a significant body of case law has established that in certain situations, the non-exercise of this power can be deemed unlawful by an appellate court, effectively establishing a "duty to clarify" (shakumei gimu). A breach of this duty (shakumei gimu ihan - 釈明義務違反) can be grounds for overturning a lower court's judgment.

Types of Clarification

The exercise of the power to clarify can manifest in several ways, broadly categorized as:

  1. Passive Clarification (消極的釈明 - shōkyokuteki shakumei): This involves the court prompting a party to supplement or make more precise their existing assertions when they are unclear, internally contradictory, or partially insufficient. For example, if a claim amount is ambiguously stated or if the chronological order of alleged events is confusing. Because passive clarification aims to elucidate what a party is already trying to assert, it is generally seen as less intrusive and less likely to compromise judicial impartiality. Consequently, the non-exercise of passive clarification when necessary is more readily deemed a breach of the duty to clarify.
  2. Active Clarification (積極的釈明 - sekkyokuteki shakumei): This involves the court more proactively suggesting new lines of argument, new factual assertions, or even different legal claims if a party appears to be entirely off-track or has failed to make appropriate or potentially winning assertions. For example, if a plaintiff is pursuing a claim on a contractual basis that seems weak, but the facts alleged might support a tort claim, the court might (cautiously) hint at this alternative. Active clarification carries a higher risk of being perceived as judicial overreach or partiality, and therefore, the duty to engage in active clarification is recognized more restrictively. The distinction between passive and active clarification can sometimes be blurry in practice.
  3. Clarification Concerning the Principle of Disposition (Shobunken Shugi): Sometimes, clarification touches upon the very definition of the subject matter of the litigation (soshōbutsu - 訴訟物), which is primarily within the parties' control under the Principle of Disposition. For example, if a plaintiff's claim is poorly formulated, the court might prompt the plaintiff to consider amending their claim to state a more appropriate or viable cause of action. This is particularly relevant in Japan, where legal representation is not mandatory at all levels of the court system, and lay litigants may struggle to correctly identify or articulate their legal claim. The 1970 Supreme Court case mentioned above is an example where such clarification, even leading to a different cause of action, was deemed permissible.

Permissibility and Necessity of Clarification

While the court may clarify, the necessity for clarification—leading to a duty—is judged by appellate courts based on specific circumstances, focusing on whether the lower court's failure to intervene resulted in a miscarriage of justice or unfairness.

Permissibility (Shakumei no Kyoyōsei): From the court's viewpoint aiming for a just trial based on sufficient information, exercising the power to clarify is generally always permissible. There are few effective legal mechanisms for parties to challenge "excessive" clarification by a judge. A formal challenge to a judge (under Article 24 CCP) is rarely successful on this ground alone, and an objection to litigation command (Article 150 CCP) is not applicable to clarification by a single judge. Moreover, once clarification is given and a party acts upon it, the appellate process of finding the clarification "excessive" and remanding the case is often futile, as the "cat is out of the bag." This practical irreversibility makes courts themselves cautious, particularly in prompting highly strategic or case-determinative assertions, such as raising the defense of the statute of limitations, which parties are generally expected to invoke themselves.

Necessity (Shakumei no Hitsuyōsei): The duty to clarify arises when clarification is deemed necessary for a just and fair trial. This necessity is judged retrospectively by appellate courts, considering factors such as:

  • Likelihood of Changing the Outcome: If it appears highly probable that clarification would have led to a different, more substantively just outcome (e.g., the party who "should have" won, based on the underlying merits, would have won).
  • Lack of "Expectancy" (kitai kanōsei - 期待可能性): If the party concerned could not reasonably have been expected to identify and rectify the insufficiency in their assertions or proof on their own, perhaps due to a lack of legal expertise or a genuine misunderstanding. This is balanced against the principle that parties should exercise due diligence and not improperly rely on the court to build their case; a failure to clarify is less likely to be deemed a breach of duty if the party's own negligence or strategic inaction was the primary cause of the deficiency, especially if it would be contrary to good faith to allow them to later complain about the lack of clarification.

The duty to clarify thus serves to bridge gaps left by a strict application of Benron Shugi, ensuring that the pursuit of party autonomy does not lead to results that are patently unjust or procedurally unfair, particularly when there's an imbalance in legal representation or sophistication between the parties.

Distinct from, though related to, the general duty to clarify factual matters is the more recently emphasized "duty to point out legal perspectives." This duty addresses situations where the court is considering basing its judgment on a legal theory, interpretation, or provision that the parties have not argued or, perhaps, even contemplated.

The rationale for this duty is primarily the prevention of "surprise attacks" based on legal grounds. If a court applies an unexpected legal perspective without giving parties the opportunity to address it, the losing party may feel ambushed and that they were not given a fair chance to present their case in light of the legal framework ultimately adopted by the court. This duty aims to enhance procedural fairness and party satisfaction.

This duty can arise in two main scenarios:

  1. Insufficient "Raw Facts" for an Unforeseen Legal Perspective: A party may have overlooked a potentially applicable legal rule, and as a result, failed to assert the primary facts necessary to support a claim or defense under that rule. In this situation, the court pointing out the legal perspective is often intertwined with its general duty to clarify facts—prompting the party to consider asserting the relevant facts.
  2. Sufficient "Raw Facts" but Divergent Legal Constructions: More critically, this duty applies when the parties have presented all the necessary primary facts for their respective positions, but the court is considering a legal construction or interpretation different from those argued by any party. Here, Benron Shugi (regarding factual assertions) might not be violated because all necessary "raw facts" are before the court. However, applying a novel legal interpretation without notice can still constitute a procedural surprise. The duty to point out legal perspectives requires the court, in such instances, to inform the parties of the legal view it is contemplating and give them an opportunity to make arguments and, if necessary, present further (likely indirect or auxiliary) evidence relevant to that legal perspective.

The Supreme Court's Stance: The 2010 Judgment

A landmark case illustrating this duty is the Supreme Court judgment of October 14, 2010 (Saikō Saibansho Dai-ichi Shōhōtei (Supreme Court, First Petty Bench), October 14, 2010, Saibansho Jihō No. 235, p. 1). The case involved a university professor's employment status. The lower courts had focused primarily on whether an agreement existed for retirement at age 80. The High Court, however, without prompting the parties for argument on the point, based part of its decision on a finding of a breach of the principle of good faith by the university concerning the notice of retirement, a legal theory not central to the parties' arguments.

The Supreme Court overturned the High Court's decision, holding that if the court intended to decide based on such a distinct legal point (breach of good faith with specific consequences concerning the timing of retirement effectiveness) which the parties had not sufficiently addressed and which was not clearly predictable from the course of litigation, it had a duty to exercise its power to clarify appropriately. This meant prompting the plaintiff (the professor) to clarify if they were asserting such a breach and giving the defendant (the university) a full opportunity to offer counterarguments and evidence on that specific legal point. This judgment is widely seen as the Supreme Court endorsing the concept of a duty to point out legal perspectives, at least in situations where the court adopts a legal construction that the parties could not reasonably have anticipated.

It is important to note, however, that judicial commentaries and scholarly analysis suggest the scope of this 2010 ruling might be somewhat nuanced. The legal construction regarding "good faith" applied by the High Court in that specific case was arguably quite novel or "idiosyncratic." Therefore, the duty to point out legal perspectives might be most strongly triggered when a court intends to apply a general legal clause (like "good faith," "abuse of rights," or "public policy") in a particularly creative or unpredictable manner, rather than in every instance where the court's precise legal reasoning subtly diverges from that of the parties. For standard applications of established legal rules, even if not explicitly argued by a party, this duty might be less stringently applied, as parties (especially if legally represented) are generally expected to be aware of relevant, established legal principles.

The existence of the court's duty to clarify and its duty to point out legal perspectives does not absolve the parties of their fundamental responsibility under Benron Shugi to diligently prepare and present their own cases. These judicial duties are supplements, not substitutes, for party diligence.

Courts must exercise these powers with care, maintaining impartiality and avoiding the appearance of taking over a party's case. There is a fine line between helpful clarification that ensures a fair hearing and improper intervention that distorts the adversarial nature of the proceedings. For instance, courts remain very cautious about actively suggesting specific defenses like the statute of limitations, which are typically viewed as matters for the party's strategic discretion to raise or waive.

Conclusion

While Japanese civil procedure is fundamentally party-driven, the image of the judge as a purely passive umpire is inaccurate. The court's power to clarify, which evolves into a duty in circumstances of necessity, and the increasingly recognized duty to point out unanticipated legal perspectives, are vital safeguards. They serve to ensure that litigation outcomes are based on a clear understanding of both facts and law, that parties are not unfairly surprised by judicial reasoning, and that the pursuit of substantive justice is not unduly thwarted by procedural missteps or a lack of legal acumen. For litigants and their representatives, understanding the potential for, and limits of, such judicial intervention is a key component of effectively navigating the Japanese legal system.
