There are quite a few more than two countries practicing common law:
The legal systems prevailing in the world can vary widely based on each country's unique history and culture. Common types include civil law, common law, religious law, customary law, and mixed legal systems. These legal systems govern the structure and operation of courts, the allocation of rights and responsibilities, and the enforcement of laws within a specific jurisdiction.
The Mexican legal system is a descendant of the old Napoleonic Code brought over from France and Spain during colonization. The two major legal traditions which are the basis of law in most countries today are generally classified as Civil Law and Common Law. Civil Law is a descendant of the Roman Laws developed under the auspices of the Emperor Justinian. The European countries tended to develop their legal systems following the more codified Civil Law, while England adopted precedents following local customs and practices which developed into what is known today as the British Common Law. As these countries colonized and expanded their respective territories, they transplanted their system of Laws. The United States and Canada follow the British Common Law, and Mexico follows the Civil Law. Obviously, this explanation is an oversimplification made by me, a layman, and intended for the edification of other layman; not for the legal scholar.
a) The use of a common measuring system makes it easier for people from different countries to communicate with each other. b) The use of a common measuring system means a maesurement in that unit has the same value anywhere in the world.
The United States has a two-party system.
The two types of law are common and statutory.
Statute law and common law are the two types of laws in Australia. Statute law refers to the legislation passed in parliament. Upon approval by parliament, statute law becomes common law. Common law emanates from the judiciary, and they are laws passed by juries and judges.
Common law can either be case law that interprets legislative statutes, or it can be case law that is only based on principles from prior case law.
i dont know
English common law & the Roman Civil law
Adversarial is an adjective that means characterizing or involving opposition or conflict. In law it refers to a scenario whereby the parties in a given dispute have the responsibility of finding and presenting evidence.
The Napoleonic code was an effort to put together texts of law redacted in the clearest way possible in order to make it accessible to all citizen. The main difference with English Common Law is that in civil law jurisdictions judicial precedent is given relatively less weight, and scholarly literature is given relatively more. The Napoleonic code expressly forbade French judges from pronouncing the law. This the legal tradition that prevails in, or is combined with common law in, almost all non-Islamic, non-common law countries.
In summary, there are two primary legal structures in the world. Some are derivatives or hybrids of each but in the main there is a Common Law System and a Civil Law System.In Common Law the ideal is that the law is applied in accordance with the local customs of the people - 'common' whereas the Civil Law has 'blanket application' if you like.Both systems generally have a standard Legislature and Executive (Parliament and Government) - see France as a Civil Law system and the United Kingdom or United States as Common Law. What this means is that in both systems there will be 'Statute Law' - that is Acts of Parliament or Congress etc.The judiciary are expected to apply these laws and interpret what they actually mean whilst doing so. In the Common Law world 'precedent' is basically the back catalogue of other judge's interpretations for today's judge to approve or disprove.The ideal of Civil Law is that the statute should be clear as to it's application that there is no need for disagreement on 'what was actually meant' - therefore erasing the need for legal 'precedent'. NB. While in England a Common Law system is used, this does not apply to the entire UK. Due to historical influences from both Europe and England (having been occupied by them), Scotland has a system inclusive of both Common and Civil Law.
