federal law
C1Formal / Legal / Academic / Political
Definition
Meaning
A system of laws created by a national (federal) government, as opposed to state or local laws. It applies uniformly across an entire federation (like the United States, Canada, or Australia).
The body of legislation, regulations, and legal principles that govern a federal union, establishing supreme authority over matters of national concern such as defence, currency, foreign policy, and interstate commerce, while often delineating powers from regional (state/provincial) laws.
Linguistics
Semantic Notes
The term is often used in contrast to 'state law' or 'local law'. It implies supremacy (e.g., federal law preempts conflicting state law in the US). It is a mass/uncountable noun when referring to the body of law, but can be used countably (e.g., 'a federal law', 'several federal laws') when referring to specific statutes.
Dialectal Variation
British vs American Usage
Differences
The UK has a unitary system, not a federal one, so 'federal law' specifically refers to foreign federations (e.g., US, Germany). In the UK context, 'national law' or 'UK law' is used. In true federations like the US, Canada, and Australia, the term is central to legal and political discourse.
Connotations
In the US: Sovereignty, national unity, and sometimes bureaucratic complexity. In the UK: Typically refers to foreign political/legal structures.
Frequency
Very high frequency in US, Canadian, and Australian contexts. Much lower and more specific in UK contexts.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'федеральный закон' for the general concept unless referring to a specific statute; use 'федеральное законодательство' for the body of law. The Russian 'федеральный закон' is a specific type of legislative act, not the general system.
Common Mistakes
- Using 'federal law' in singular for a specific act without an article (e.g., 'They passed federal law'). Correct: 'They passed a federal law'.
- Using it to describe the national law of a non-federal country (e.g., UK, France).

FAQ
Frequently Asked Questions
No. Constitutional law is the body of law interpreting a constitution. Federal law includes all laws made by the federal government under that constitution, including statutes and regulations, which are broader than just constitutional interpretation.
In systems like the United States, yes. This is known as the 'dual sovereignty' doctrine. The same conduct may constitute an offence against both the federal and state governments, and both can prosecute separately.
No. The UK has a unitary system with devolved administrations. Its national law is simply 'UK law' or 'statute law'. 'Federal law' is used in the UK mainly to discuss other countries like the US or Germany.
In a federation, the principle of 'federal supremacy' or 'preemption' applies. Where a valid federal law and a state law conflict, the federal law prevails and the state law is invalidated to the extent of the conflict.
