Subsequently, one may also ask, are laws the same in every country?
Different populations of people live under laws that are suited to their cultures, needs and histories. You don't need to go to different countries to see this. Every state in the U.S. makes its own laws in areas such as police powers, where the Federal government does not claim supremacy under the Constitution.
Also Know, what countries use common law? 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.
Beside above, which country has no law?
Somalia
Why are laws different in different countries?
Since so many countries use a Civil Law system, it is easy to identify common traits despite the numerous differences of each country's own legal code. Because of this, the judiciary plays a far greater role in Common Law systems than in Civil Law systems, as their judgements are those that set the precedents.
