Legal Definitions - Uncodified

Uncodified refers to legal principles, rules, or practices that have not been formally written down and enacted into statutes or comprehensive legal codes by a legislative body. Instead, these principles often originate from judicial decisions made over many years (known as common law), from long-standing customs and traditions, or from widely accepted conventions that operate as law without being explicitly written in a statute book.

Here are some examples to illustrate this concept:

• Common Law Duty of Care: In many legal systems, the foundational concept of a "duty of care" in negligence law was largely uncodified for centuries. Before specific statutes began to address particular types of negligence, courts established that individuals have a general obligation to act reasonably to avoid causing foreseeable harm to others. This principle wasn't created by a specific legislative act but emerged from a series of judicial decisions, making it an uncodified common law rule that judges applied to new situations.

• Constitutional Conventions: In countries with unwritten constitutions, such as the United Kingdom, many crucial aspects of government operation are uncodified. For instance, the convention that the monarch will always grant Royal Assent to bills passed by Parliament, effectively turning them into law, is a powerful unwritten rule. While the monarch technically retains the power to refuse, this has not happened for hundreds of years. This expectation is a deeply ingrained constitutional convention, not a statutory requirement, and operates without being codified in an act of Parliament.

• Customary International Law: Before comprehensive treaties like the United Nations Convention on the Law of the Sea were established, many principles governing the use of the oceans were uncodified. For example, the concept that a state has sovereignty over its territorial waters extending a certain distance from its coastline was largely based on customary international law. This understanding developed over centuries through the consistent practice of states and their mutual recognition of these boundaries, rather than from a single, written international statute or treaty.
