The '''Emergency Powers (Defence) Act 1939''' (2 & 3 Geo. 6. c. 62) was an act of the Parliament of the United Kingdom. The act was emergency legislation passed just prior to the outbreak of World War II by the Parliament of the United Kingdom to enable the British government to take up emergency powers to prosecute the war effectively. It contained clauses giving the government wide powers to create '''Defence Regulations''' by Order in Council. These regulations governed almost every aspect of everyday life in the country during the War. Two offences under the regulations (forcing safeguards and looting) were punishable with death.<ref name=":0">{{cite book |editor1-last=Butler |editor1-first=T. R.

As of 2023, at least one Regulation (relating to the use of service personnel to perform agricultural and other "urgent work of national importance") remains in force.

==Passage and effect== On 24 August 1939, following the announcement of the Nazi–Soviet Pact the previous day, the House of Commons was recalled from its summer recess to pass the Emergency Powers (Defence) Bill, which gave authority to implement the Defence Regulations. The Act was originally intended to be in force for only one year, and made general provision for prosecuting the war effort. In particular, it provided for the following:{{cquote|'''1'''. (1) Subject to the provisions of this section, His Majesty may by Order in Council make such Regulations (in this Act referred to as "Defence Regulations") as appear to him to be necessary or expedient for securing the public safety, the defence of the realm, the maintenance of public order and the efficient prosecution of any war [in which] His Majesty may be engaged, and for maintaining supplies and services essential to the life of the community.

(2) Without prejudice to the generality of the powers conferred by the preceding subsection, Defence Regulations may, so far as appears to His Majesty in Council to be necessary or expedient for any of the purposes mentioned in that subsection:-

(a) Make provision for the apprehension, trial, and punishment of persons offending against the Regulations and for the detention of persons whose detention appears to the Secretary of State to be expedient in the interests of the public safety or the defence of the realm;

(b) authorise - :(i) the taking of possession or control, on behalf of His Majesty, of any property or undertaking; :(ii) the acquisition, on behalf of His Majesty, of any property other than land;

(d) provide for amending any enactment, for suspending the operation of any enactment, and for applying any enactment with or without modification.

[...]

(5) Nothing in this section shall authorise the imposition of any form of compulsory naval, military or air force service or any form of industrial conscription, or the making of provision for the trial by courts martial of persons not being persons subject to the Naval Discipline Act, to military law or to the Air Force Act. }}

The bill completed all its parliamentary stages, including royal assent, on that day.{{Sfn|Simpson|1994|p=49}} The question of compensation was not directly addressed by the bill, but the subsequent Compensation (Defence) Act 1939 (2 & 3 Geo. 6. c. 75) established a statutory compensation scheme in respect of land, vessels, vehicles, aircraft and other property a week later.{{sfn|Balogh|1943|p=196}}

== Defence Regulations == The Defence Regulations were Orders in Council and could amend any primary or secondary legislation within the limits of the enabling acts to allow the effective prosecution of the war.

The regulations existed in draft form, constantly revised, throughout the years between the world wars.{{Sfn|Simpson|1994|pp=43–47}} In early 1939 it was decided that since a war might break out without warning or without time to pass an act of Parliament to bring in emergency regulations, the regulations should be split into two codes. Code A would be needed immediately if war broke out and could be passed in peacetime, while Code B, containing more severe restrictions on civil liberties, would be brought in later. In order not to alert the public to the existence of Code B, Code A was simply numbered consecutively.{{Sfn|Simpson|1994|pp=48–49}}

Taken together, the Defence Regulations provided the legal basis for a number of measures aimed at the Home Front including the establishment of the Home Guard, the institution of rationing, and nighttime blackouts.<ref>{{Cite web |title=Home Front |url=https://www.parliament.uk/about/living-heritage/transformingsociety/private-lives/yourcountry/overview/homefront/ |access-date=31 December 2023 |website=UK Parliament}}</ref>

Originally the regulations did not create any capital offences, since the law of treason was thought to be sufficient. Defence Regulation 2A provided that "If, with intent to assist the enemy, any person does any act which is likely to assist the enemy or to prejudice the public safety, the defence of the realm or the efficient prosecution of the war, he shall be liable to penal servitude for life."<ref>{{cite hansard|title=Offences (Penalties)|jurisdiction=United Kingdom|house=House of Commons|date=20 November 1940|volume=365|url=https://api.parliament.uk/historic-hansard/written-answers/1940/nov/20/offences-penalties#S5CV0365P0-08238}}</ref>

However, in 1940 amendments to the regulations created two capital offences: "forcing safeguards" (breaking through roadblocks etc.) under regulation 1B, and looting under regulation 38A.<ref name=":0" /> A third new capital offence, called treachery, was created soon afterwards by the Treachery Act 1940.

The '''{{visible anchor|Emergency Powers (Defence) (No. 2) Act 1940}}''' (3 & 4 Geo. 6. c. 45) enabled the creation of special courts to administer criminal justice in war zones, as well as authorizing them to punish offenders for violating the Defence Regulations.{{sfn|Jennings|1940|p=133}}

== Continuance and repeal == After the end of the war, the Defence Regulations were continued in force by the Supplies and Services (Transitional Powers) Act 1945 (9 & 10 Geo. 6. c. 10) and later by the Emergency Laws (Transitional Provisions) Act 1946 (9 & 10 Geo. 6. c. 26). They continued to be amended periodically, including by the Defence Regulations (No. 2) Order 1949 and the Defence Regulations (No. 3) Order 1949.<ref>{{Cite book |last= |first= |url=https://books.google.com/books?id=pohQAQAAIAAJ |title=Statutory Instruments Other Than Those of a Local, Personal, Or Temporary Character for the Year 1949 |date=1949 |publisher=H.M.
