Summary
In Tang Huixian & 19 Ors v Soka Gakkai Singapore [2025] SGHC 131, the High Court considered whether a religious association’s decision to expel members from its organisation was made in breach of natural justice, or was irrational/unreasonable such that it should be declared null and void. The claimants were members of Soka Gakkai Singapore (“SGS”), a Buddhist organisation practising Nichiren Buddhism, and they were expelled following internal processes connected to their participation in an informal study and practice group known as the Solidarity of Genuine Sensei’s Disciples (“SGSD”).
The court approached the dispute as one raising administrative-law style questions, even though the expulsion decision arose within a private religious organisation. The central issues concerned (i) the scope and standard of judicial review applicable to decisions of religious associations, (ii) whether the disciplinary process complied with the requirements of natural justice—particularly the rule against bias and the right to a fair opportunity to be heard—and (iii) whether the expulsion decisions were irrational or unreasonable in the sense associated with Wednesbury unreasonableness. Applying these principles to the evidence, the court ultimately dismissed the claimants’ application for declarations that the expulsion decisions were void.
What Were the Facts of This Case?
SGS is a Buddhist organisation registered as a society in 1972 and as a charity in 1985. It is part of an international network of affiliated organisations under Soka Gakkai International (“SGI”), and it is the only constituent organisation of SGI in Singapore. The management of SGS’s affairs is vested in its Management Committee (“MC”) under Article 8 of SGS’s Constitution. The Constitution also provides for expulsion of members in specified circumstances, subject to a disciplinary inquiry and an opportunity for the member to defend and justify or explain their conduct.
The claimants participated in SGSD, which the claimants described as an informal group of family and friends who studied and practised Nichiren Buddhism together and encouraged one another. The group’s activities included monthly study sessions over Zoom, pooling funds for study materials, and developing a mobile application. The claimants also characterised SGSD as akin to a Bible study group. SGS, however, viewed the formation and operation of SGSD as unorthodox and potentially harmful to the interests and harmony of SGS. SGS’s position was that SGSD functioned as an organised group within SGS, and that its existence and activities warranted investigation.
In August 2022, SGS received information about SGSD from one of its members, Gerald Aw Yee Wei (“Mr Aw”), who was apparently a former member of SGSD and also the former husband of the 11th claimant. Around December 2022, the MC formed the view that SGSD, if true, would be unacceptable and contrary to SGS’s interests and harmony, and that further investigation was required. Separately, the Buddhist Council of SGS—responsible for matters of faith—took the view that alleged SGSD members who were leaders of SGS would have their leadership status revoked pending investigations.
In February 2023, SGS held training sessions for leaders. The claimants alleged that during these sessions, senior leaders made statements about SGSD that were hostile and demonstrated bias or prejudgment. The statements included that SGSD “held their own activities, completely ignoring” SGS, that they “solicited donations from members” in violation of SGS principles, and that they “spread resentment and dissatisfaction towards SGS and its central figures.” The claimants further relied on the assertion that the “most serious offence” was disrupting the harmony of the Buddhist order, described as one of the five cardinal sins in Buddhism. The claimants argued that these statements showed apparent bias because some of the individuals who made them were later members of the Disciplinary Committees (“DCs”) and/or the MC.
SGS invited the claimants to dialogue sessions between February and March 2023. Seven claimants responded. Each dialogue session involved designated leaders of SGS (the “Designated Leaders”) and an individual claimant, with the exception of the 6th claimant who met a designated leader alone. The dialogue sessions were intended to address the claimants’ involvement in SGSD and to provide a forum for discussion before disciplinary steps were taken.
Following the dialogue sessions and further internal steps, SGS conducted disciplinary committee hearings (“DCHs”) and ultimately expelled the claimants from membership. The claimants’ case focused on the fairness of the disciplinary process, including whether the decision-makers were biased or had prejudged the matter, whether the claimants were given a fair opportunity to be heard, and whether the expulsion decisions were irrational or unreasonable. A significant factual feature was that the claimants did not attend the DCHs, which SGS treated as relevant to whether they had been afforded a real opportunity to defend themselves.
What Were the Key Legal Issues?
The case raised questions about how natural justice principles apply in the context of a private religious association’s disciplinary decisions. Although SGS is not a public authority in the orthodox sense, the court treated the expulsion decisions as amenable to judicial review principles, including the implied requirements of fairness in contractual or constitutional arrangements between members and the association. The first legal issue was therefore whether the expulsion decisions were made in breach of natural justice, including the rule against bias and the requirement of a fair opportunity to be heard.
A second legal issue concerned bias or prejudgment. The claimants relied on the February 2023 training session statements to argue that the disciplinary decision-makers had already formed views about SGSD and the claimants’ conduct. The court had to determine whether those statements, in their context, amounted to actual bias, apparent bias, or prejudgment such that the disciplinary process was unfair.
A third issue was whether the expulsion decisions were irrational or unreasonable. The court had to consider the extent to which rationality standards—associated with Wednesbury unreasonableness—are relevant when reviewing decisions of religious associations, particularly where the association’s determinations involve matters of faith, internal discipline, and organisational harmony.
How Did the Court Analyse the Issues?
The court began by framing the claimants’ application as one seeking declarations that SGS’s expulsion decisions were null and void because they were made in breach of natural justice or were irrational/unreasonable. The judge emphasised that the case required careful calibration: the court must respect the autonomy of religious organisations in managing their internal affairs, while still ensuring that minimum fairness requirements are met when an association’s rules provide for expulsion and when members’ rights are affected. This balancing exercise is particularly important in religious contexts, where doctrinal and organisational considerations may be intertwined.
On natural justice, the court examined the constitutional framework of SGS. Article 7(b) of SGS’s Constitution empowered the committee to expel members when the member had ceased to be a follower or believer of Nichiren Daishonin’s teachings, breached provisions of the Constitution, rules and by-laws, or acted against the interests or harmony of the association, or used the association’s name for personal gain. Crucially, Article 7(b)(ii) required that before expulsion, the member’s conduct be inquired into by the Management Committee or a Disciplinary Committee and/or Board of Inquiry, and that the member be given “full opportunity” to defend himself and justify or explain conduct. The court treated this as a contractual and procedural safeguard that must be respected.
The court then addressed the claimants’ reliance on the February 2023 training session statements. The claimants tendered audio recordings and transcripts/translations of the statements. SGS objected on hearsay grounds and argued that the recordings should not be given weight. The judge analysed the evidential framework for affidavit proceedings in originating applications, including the relevance of the Evidence Act 1893 and the common law rules of evidence. The court accepted that the recordings were tendered not for the truth of the statements’ contents but for the fact that the statements were made, which was said to be relevant to whether bias or prejudgment existed. The court therefore treated the hearsay objection as not determinative of admissibility in the way SGS suggested.
Substantively, the court considered whether the training session statements demonstrated bias or prejudgment against the claimants. The judge’s approach reflects a common judicial review theme: bias is not established merely because decision-makers have strong views, but rather where there is a real likelihood that the decision-maker was not open-minded, or where the process would appear unfair to a reasonable observer. In this case, the court had to consider the nature of the statements, their context (training sessions for leaders), and the procedural safeguards that SGS adopted thereafter, including dialogue sessions and disciplinary hearings. The court also considered that some statements were general in character—directed at SGSD as a phenomenon—rather than targeted findings about individual claimants’ guilt.
Another key component of the analysis concerned the claimants’ failure to attend the DCHs. The judge treated attendance as a practical measure of whether the claimants were afforded a genuine opportunity to be heard. Where an association provides a process for defence and explanation, and the member declines to participate, the fairness inquiry may be affected. The court’s reasoning indicates that natural justice does not guarantee a favourable outcome or a perfect process in the abstract; rather, it requires that the member be given a meaningful chance to present their case. The claimants’ non-attendance undermined their argument that they were denied a fair opportunity.
On irrationality/unreasonableness, the court applied rationality principles in a manner consistent with the judicial review framework. The judge considered whether SGS’s decisions were irrational in the Wednesbury sense—meaning that the decisions were so unreasonable that no reasonable decision-maker could have reached them. In religious association contexts, the court recognised that internal determinations about doctrine, discipline, and organisational harmony often involve matters that are not readily substitutable by a court’s own view. Accordingly, the court was cautious not to convert judicial review into a merits review. Instead, it asked whether SGS’s decisions were grounded in the constitutional criteria and whether the disciplinary process was conducted fairly and rationally.
Finally, the court’s reasoning reflected the principle that natural justice and rationality are applied with sensitivity to the institutional setting. The court did not treat the association’s autonomy as absolute; it treated it as a factor in assessing what fairness requires and what level of scrutiny is appropriate. Where the association’s rules were followed, where members were invited to engage, and where the claimants were given opportunities to defend themselves but did not take them, the court was less likely to find a breach of natural justice or irrationality.
What Was the Outcome?
The High Court dismissed the claimants’ application for declarations that SGS’s expulsion decisions were made in breach of natural justice or were irrational/unreasonable. The practical effect of the decision is that the expulsion decisions remained valid, and the claimants did not obtain the relief sought to nullify their expulsions.
For members challenging disciplinary outcomes in religious organisations, the case underscores that courts will examine procedural fairness and bias allegations, but will also consider whether the association provided a real opportunity to be heard and whether the claimant engaged with the process. Non-attendance at disciplinary hearings can be decisive in undermining a “denial of fair opportunity” argument.
Why Does This Case Matter?
Tang Huixian & 19 Ors v Soka Gakkai Singapore is significant because it clarifies how natural justice principles and rationality review operate when a religious association expels members. It demonstrates that even in private organisational settings, courts may apply administrative-law style fairness concepts—particularly where the association’s constitution provides for expulsion and where members’ rights are materially affected.
For practitioners, the case is useful in two ways. First, it provides a structured approach to bias and prejudgment arguments based on statements made earlier in the organisation. It suggests that courts will look at context, whether statements were general or targeted, and whether later procedural safeguards mitigated any appearance of prejudgment. Second, it highlights the importance of participation: where a claimant does not attend disciplinary hearings, it becomes harder to argue that the process denied a fair opportunity to be heard.
More broadly, the decision reinforces the judiciary’s reluctance to substitute its own view for a religious association’s internal assessments of doctrine, discipline, and organisational harmony. This has implications for future challenges: claimants must focus on identifiable procedural unfairness, demonstrable bias, or decisions that cross the high threshold of irrationality, rather than disagreements about the association’s substantive conclusions.
