The phrase “source of law” literally means where rules of law are found. However, the phrase is often used to describe
• The origins of the rules and principles which constitute the law applicable in a country at a given time. These are the formal sources.
• The source of force and validity of the rules and principles applicable as law in a country. These are the legal source.
• The materials from which rules and principles of law developed. These are the material sources.
• The factors that influenced the development of the rules of law. These are the historic sources. Hence the phrase „source of law‟ refers to the historical, material, formal and legal sources of law.
