This book explains Indonesia’s complex legal system and how it works. Covering a wide range of substantive topics from public to private law, including commercial, criminal, and constitutional law, it is the first comprehensive survey of Indonesian law in English. Offering clear answers to practical problems of current law, each chapter sets out relevant laws and leading court decisions, accompanied by an explanation of how the law works in practice, with an analytical critique. The book begins with an account of Indonesia’s Constitution and the key state agencies, before moving to the lawmaking process, decentralization, the judicial system and court procedure, and the legal profession (advocates, notaries, and legal aid). Part II covers traditional customary law (adat), land law, and environmental law, including forest law. Part III focuses on criminal law and procedure, including investigation, arrest, trial, sentencing, and appeals. It also covers human rights law and the law on corruption. Part IV deals with civil law, and covers civil liability, contracts, companies and other business vehicles, labour, foreign investment, taxation, insolvency, banking, competition, and media law. The book concludes in Part V with an account of Indonesia’s complex family law and inheritance system for both Muslims and non-Muslims. The book has an extensive glossary of legal terms, and detailed tables of legislation and court decisions, designed as unique resources for lawyers, policymakers, and researchers.
