The Swiss Constitution is renowned for several distinctive features: direct citizen influence through initiatives and referendums, a unique "bottom-up" federal structure reflecting cultural and linguistic diversity, a multi-party collegiate executive, and a singular model of constitutional justice. This revised third edition addresses the significant development of Swiss constitutional law, particularly through the excessive use of urgency legislation during the Covid-19 pandemic and challenges to neutrality amidst global conflicts. This book is addressed to lawyers, political scientists, politicians, diplomats, journalists and anyone seeking a clear, precise understanding of Switzerland's governance. The authors provide a concise overview of the Swiss constitutional system, enriched by comparisons with other well-known constitutions. A detailed index ensures quick access to key information.
