Case opinions
The test for standing in constitutional law challenges is that of the Karaha Bodas test.

Tan Eng Hong v. Attorney-General [1] was a constitutional law case where the Singapore Court of Appeal overturned a decision made by the Singapore High Court against Tan Eng Hong ("Tan"). The High Court had found that whilst Tan had locus standi to bring an application challenging the constitutionality of Section 377A of the Penal Code, the application disclosed no real controversy to be adjudicated.[2] Thus, the Assistant Registrar’s original decision[3] to strike out Tan’s application was upheld.


Tan subsequently appealed against the High Court’s decision, attempting to establish that he had an arguable case as this would be sufficient to prevent the striking out of his application.[4]


The Court of Appeal considered in detail whether the test for locus standi in applications involving constitutional rights was different from, or less strict[5] than the test laid down in Karaha Bodas Co. LLC v. Pertamina Energy Trading Ltd. [6] (“Karaha Bodas”). It was held that the case of Eng Foong Ho v. Attorney-General[7] (“Eng Foong Ho”) did not provide support for a lower threshold of locus standi.[8] Utilizing the case of Chan Hiang Leng Colin v. Minister for Information and the Arts[9] (“Colin Chan”) as support,[10] the court affirmed the applicability of the Karaha Bodas test, holding that an applicant must demonstrate a violation of constitutional rights to be granted locus standi.[11] Additionally, it was decided that the “real controversy” requirement went to the court’s discretion, conferring discretion upon the court to hear a case in the absence of a real controversy. The Court of Appeal further held that a subsisting prosecution was not necessary to establish a violation of constitutional rights,[12] and endorsed the High Court’s view that a real and credible threat of future prosecution would suffice.[13] Also, the mere existence of an allegedly unconstitutional statute may also suffice to demonstrate a violation of constitutional rights.[14]


Two other legal issues were also considered; namely, whether the applicable test for locus standi was satisfied on the facts, and whether the facts raised any real controversy to be adjudicated. The Court of Appeal answered both questions in the affirmative, and eventually decided in favor of Tan.
