List of national legal systems
Common law is currently in practice in Ireland, most of the United Kingdom (England and Wales and Northern Ireland), Australia, New Zealand, Bangladesh, India (excluding Goa), Pakistan, South Africa, Canada (excluding Quebec), Hong Kong, the United States (on a state level excluding Louisiana), and many other places. In addition to these countries, several others have adapted the common law system into a mixed system. For example, Nigeria operates largely on a common law system, but incorporates religious law.
Fair use
Sources differ on whether fair use is fully recognized by countries other than the United States. American University's "infojustice.org" published a compilation of portions of over 40 nations' laws that explicitly mention fair use or fair dealing, and asserts that some of the fair dealing laws, such as Canada's, have evolved (such as through judicial precedents) to be quite close to those of the United States. This compilation includes fair use provisions from Bangladesh, Israel, South Korea, the Philippines, Sri Lanka, Taiwan, Uganda, and the United States. However, Paul Geller's 2009 "International Copyright Law and Practice" says that while some other countries recognize similar exceptions to copyright, only the United States and Israel fully recognize the concept of fair use.
