The principle in law that the rules are not changed in the middle of game, is embodied in the notion that legislation should apply prospectively. This study analyzes the legal constraints on retroactive legislation and the presumption of prospectivity and constitutional limits on such lawmaking.

Offering a unique perspective on an overlooked subject – the relationship between time, change, and lawmaking – this edited collection brings together world-leading experts to consider how time considerations and social, political and technological change affect the legislative process, the interpretation of laws, the definition of the powers of the government and the ability of legal orders to promote innovation. Divided into four parts, each part considers a different form of interaction between time and law, and change. The first part offers legal, theoretical and historical perspectives on the relationship between time and law, and how time shaped law and influences legal interpretation and constitutional change. The second part offers the reader an analysis of the different ways in which courts approach the impact of time on law, as well as theoretical and empirical reflections upon the meaning of the principle of legal certainty, legitimate expectations and the influence of law over time. The third part of the book analyses how legislation and the legislative process addresses time and change, and the various challenges they create to the legal order. The fourth and final part addresses the complex relationship between fast-paced technological change and the regulation of innovations.

Derived from the renowned multi-volume International Encyclopaedia of Laws, this very useful analysis of constitutional law in Belgium provides essential information on the country’s sources of constitutional law, its form of government, and its administrative structure. Lawyers who handle transnational matters will appreciate the clarifications of particular terminology and its application. Throughout the book, the treatment emphasizes the specific points at which constitutional law affects the interpretation of legal rules and procedure. Thorough coverage by a local expert fully describes the political system, the historical background, the role of treaties, legislation, jurisprudence, and administrative regulations. The discussion of the form and structure of government outlines its legal status, the jurisdiction and workings of the central state organs, the subdivisions of the state, its decentralized authorities, and concepts of citizenship. Special issues include the legal position of aliens, foreign relations, taxing and spending powers, emergency laws, the power of the military, and the constitutional relationship between church and state. Details are presented in such a way that readers who are unfamiliar with specific terms and concepts in varying contexts will fully grasp their meaning and significance. Its succinct yet scholarly nature, as well as the practical quality of the information it provides, make this book a valuable time-saving tool for both practising and academic jurists. Lawyers representing parties with interests in Belgium will welcome this guide, and academics and researchers will appreciate its value in the study of comparative constitutional law.

The United States Constitution has already been interpreted to provide a variety of family-related protections which, if applied consistently, also protect same-sex couples and their children. Only by radically reformulating and severely undermining existing protections can courts and commentators justify the claim that the Federal Constitution does not offer a wealth of family protections, including the right to marry a same-sex partner. Discussing the constitutional implications of civil unions with a special focus on how they might be treated in the interstate context, Strasser explains how the courts and commentators have reworked and significantly weakened a variety of constitutional protections in their attempts to establish that same-sex couples are not afforded constitutional protections. He further suggests that the constitutional protections for religion support rather than undermine the constitutional protection of same-sex unions.
