Answer: True.
Explanation: Common Law is a term used in the legal sciences to refer to a system of law whose application of norms and rules are not written but sanctioned by custom or case law. Such a form of law stems from the conception of English medieval law which, when administered by the courts of the kingdom, reflected the common customs of those who lived in it. This legal system is in force in the United Kingdom and most of the countries that were colonized by this country.
