Indonesia’s vast legal system is often misunderstood due to its complexity and pluralism. It is an amalgamation of inherited Dutch civic and criminal codes, 76 years of national law development under both authoritarian and democratic administrations, as well as revivals of pre-colonial Islamic and customary adat law. As Indonesia’s economy and population continue to grow to among the largest in the world, it has never been more important to understand how the country’s laws are evolving. The world’s third-largest democracy and home to the largest Muslim population, Indonesia is a law-based nation but faces an array of challenges in the ongoing reformation of the legal system. Tackling corruption, protecting the environment, court reform, and implications of technological change are just a few of the issues.
