A Treatise on Singapore Constitutional Law explores how constitutional law operates within the context of a non-liberal, secular constitutional democracy, within a religiously and racially diverse social setting. This treatise is concerned with both theory and doctrine, with explaining the black letter rules of constitutional practice and their underlying rationales, as well as critically examining how they work in practice. It seeks to draw out the broader significance of legal rules by identifying their underlying legal philosophy and engages the normative, conceptual and empirical dimensions of constitutional law, to present a thorough study of the law in Singapore. This book addresses both what the state of the law “is”, and evaluates this against what it “ought” to be or to aspire towards.
