Criminal law in some countries or for some conspiracies may require that at least one overt act be undertaken in furtherance of that agreement, to constitute an offense. There is no limit on the number participating in the conspiracy and, in most countries, the plan is the crime, so there is no requirement that any steps have been taken to put the plan into effect (compare

to create new offences and, following the Law Commission Report No. 76 on Conspiracy and Criminal Law Reform, the Criminal Law Act 1977 produced a statutory offence and abolished all the common law varieties of conspiracy, except two: that of conspiracy to defraud, and that of conspiracy to corrupt public morals or to outrage public decency.


Conspiracy to defraud

Section 5(2) of the Criminal Law Act 1977 preserved the common law offence of conspiracy to defraud. Conspiracy to defraud was defined in ''Scott v Commissioner of Police of the Metropolis'' per Viscount Dilhorne:


Conspiracy to corrupt public morals or to outrage public decency

Section 5(3) Criminal Law Act 1977 preserved the common law offence of conspiracy to corrupt public morals or of conspiracy to outrage public decency. Conspiracy to corrupt public morals is an offence under the common law of England and Wales. Conspiracy to outrage public decency is an offence under the common law of England and Wales. Section 5(1) of the Criminal Law Act 1977 does not affect the common law offence of conspiracy if, and in so far as, it can be committed by entering into an agreement to engage in conduct which tends to corrupt public morals, or which outrages public decency, but which does not amount to or involve the commission of an offence if carried out by a single person otherwise than in pursuance of an agreement. One authority maintains that conspiracy to "corrupt public morals" has no definitive case law, that it is unknown whether or not it is a substantive offence, and that it is unlikely that conspirators will be prosecuted for this offence. These two offences cover situations where, for example, a publisher encourages immoral behaviour through explicit content in a magazine or periodical, as in the 1970 case of ''Knuller (Publishing, Printing and Promotions) Ltd v Director of Public Prosecutions'', which ultimately was decided in 1973 by the House of Lords. In the 1991 case of ''R v Rowley'', the defendant left notes in public places over a period of three weeks offering money and presents to boys with the

of luring them for immoral purposes, but there was nothing lewd, obscene or disgusting in the notes, nor were they printed by a news magazine at the behest of Rowley, which would have invoked the element of conspiracy. The judge ruled that the

was entitled to look at the purpose behind the notes in deciding whether they were lewd or disgusting. On appeal against conviction, it was held that an act outraging public decency required a deliberate act which was in itself lewd, obscene or disgusting, so Rowley's motive in leaving the notes was irrelevant and, since there was nothing in the notes themselves capable of outraging public decency, the conviction was quashed.


Statutory offence

This offence was created as a result of the Law Commission's recommendations in their Report, Conspiracy and Criminal Law Reform, 1976, Law Com No 76. This was part of the commission's programme of codification of the criminal law. The eventual aim was to abolish all the remaining common law offences and replace them, where appropriate, with offences precisely defined by statute. The common law offences were seen as unacceptably vague and open to development by the courts in ways which might offend the principle of certainty. There was an additional problem that it could be a criminal conspiracy at common law to engage in conduct which was not in itself a criminal offence: see Law Com No 76, para 1.7. This was a major mischief at which the 1977 Act was aimed, although it retained the convenient concept of a common law conspiracy to defraud: see Law Com No 76, paras 1.9 and 1.16. Henceforward, according to the Law Commission, it would only be an offence to agree to engage in a course of conduct which was itself a criminal offence. Section 1(1) of the Criminal Law Act 1977 provides: Section 1A (inserted by the Criminal Justice (Terrorism and Conspiracy) Act 1998, s. 5) bans conspiracies part of which occurred in England and Wales to commit an act or the happening of some other event outside the United Kingdom which constitutes an offence under the law in force in that country or territory.

Exceptions

* Under section 2(1) the intended victim of the offence cannot be guilty of conspiracy. * Under section 2(2) there can be no conspiracy where the only other person(s) to the agreement are:


''Mens rea''

There must be an agreement between two or more persons. The ''mens rea'' of conspiracy is a separate issue from the ''mens rea'' required of the substantive crime. Lord Bridge in ''R v Anderson'' – quoted in ''R v Hussain'' said: Lord Bridge in ''R v Anderson'' also said: It is not therefore necessary for any action to be taken in furtherance of the criminal purpose in order for a conspiracy offence to have been committed. This distinguishes a conspiracy from an attempt (which necessarily does involve a person doing an act): see Criminal Attempts Act 1981.


Things said or done by one conspirator

Lord Steyn in ''R v Hayter'' said:


History

According to Edward Coke, conspiracy was originally a statutory remedy against false accusation and prosecution by "a consultation and agreement between two or more to appeal or indict an innocent man falsely and maliciously of felony, whom they cause to be indicted and appealed; and afterward the party is lawfully acquitted". In '' Poulterer's Case'', 77 Eng. Rep. 813 (K.B. 1611), the court reasoned that the thrust of the crime was the confederating of two or more, and dropped the requirement that an actual indictment of an innocent take place, whereby precedent was set that conspiracy only need involve an
attempt An attempt to commit a crime occurs if a criminal has an intent to commit a crime and takes a substantial step toward completing the crime, but for reasons not intended by the criminal, the final resulting crime does not occur.''Criminal Law - ...
ed crime, and that the agreement was the act, which enabled subsequent holdings against an agreement to commit any crime, not just that originally proscribed.


Conspiracy to trespass

In ''Kamara v Director of Public Prosecutions'', nine students, who were nationals of
Sierra Leone Sierra Leone,)]. officially the Republic of Sierra Leone, is a country on the southwest coast of West Africa. It is bordered by Liberia to the southeast and Guinea surrounds the northern half of the nation. Covering a total area of , Sierr ...
, appealed their convictions for conspiracy to trespass, and unlawful assembly. These persons, together with others who did not appeal, conspired to occupy the London premises of the High Commissioner for Sierra Leone in order to publicize grievances against the government of that country. Upon their arrival at the commission, they threatened the caretaker with an imitation firearm and locked him in a reception room with ten other members of the staff. The students then held a press conference on the telephone, but the caretaker was able to contact the police, who arrived, released the prisoners, and arrested the accused. In this case the Court felt that the public interest was clearly involved because of the statutory duty of the British Government to protect diplomatic premises. Lauton J delivered the judgment of the Court of Appeal dismissing the appeal from conviction.


Conspiracy to corrupt public morals and conspiracy to outrage public decency

These offences were at one time tied up with prostitution and homosexual behaviour. After the Second World War, due to the fame of several convicts, the Wolfenden report was commissioned by government, and was published in 1957. Thereupon came the publication of several books, both pro and contra the report. Of these books we can isolate two representatives:
Lord Devlin Patrick Arthur Devlin, Baron Devlin, PC, FBA (25 November 1905 – 9 August 1992) was a British judge and legal philosopher. The second-youngest English High Court judge in the 20th century, he served as a Lord of Appeal in Ordinary from ...
wrote in favour of societal norms, or morals, while H. L. A. Hart wrote that the state could ill regulate private conduct. In May 1965, Devlin is reported to have conceded defeat. The Street Offences Act 1959 prohibited England's prostitutes from soliciting in the streets. One Shaw published a booklet containing prostitutes' names and addresses; each woman listed had paid Shaw for her advertisement. A 1962 majority in the House of Lords not only found the appellant guilty of a statutory offence (living on the earnings of prostitution), but also of the "common law misdemeanour of conspiracy to corrupt public morals".''Shaw v DPP''

, the appellants were directors of a company which published a fortnightly magazine. On an inside page under a column headed "Males" advertisements were inserted inviting readers to meet the advertisers for the purpose of homosexual practices. The appellants were convicted on counts of # conspiracy to corrupt public morals, and # conspiracy to outrage public decency. The appeal on count 1 was dismissed, while the appeal on count 2 was allowed because in the present case there had been a misdirection in relation to the meaning of "decency" and the offence of "outrage". The list of cases consulted in the ''ratio decidendi'' is lengthy, and the case of ''Shaw v DPP'' is a topic of furious discussion.


Conspiracy to effect a public mischief

In ''Withers v Director of Public Prosecutions'', which reached the House of Lords in 1974, it was unanimously held that conspiracy to effect a public mischief was not a separate and distinct class of criminal conspiracy. This overruled earlier decisions to the contrary effect. The Law Commission published a consultation paper on this subject in 1975.


Conspiracy to murder

The offence of conspiracy to murder was created in statutory law by section 4 of the Offences Against the Person Act 1861.

United States

Conspiracy has been defined in the United States as an agreement of two or more people to commit a crime, or to accomplish a legal end through illegal actions. A conspiracy does not need to have been planned in secret to meet the definition of the crime. Conspiracy law usually does not require proof of specific intent by the defendants to injure any specific person to establish an illegal agreement. Instead, usually the law requires only that the conspirators have agreed to engage in a certain illegal act. In most U.S. jurisdictions, for a person to be convicted of conspiracy, not only must he or she agree to commit a crime, but at least one of the conspirators must commit an overt act (the ''
actus reus (), sometimes called the external element or the objective element of a crime, is the Law Latin term for the "guilty act" which, when proved beyond a reasonable doubt in combination with the ("guilty mind"), produces criminal liability in t ...
'') in furtherance of the crime. However, in '' United States v. Shabani'' the U.S. Supreme Court ruled that this "overt act" element is not required under the federal drug conspiracy statute, 21 U.S.C. section 846. The conspirators can be guilty even if they do not know the identity of the other members of the conspiracy.

is somewhat representative of other jurisdictions. A punishable conspiracy exists when at least two people form an agreement to commit a crime, and at least one of them does some act in furtherance to committing the crime. Each person is punishable in the same manner and to the same extent as is provided for the punishment of the crime itself. One example of this is the

case, where one twin sister attempted to hire two youths to have her twin sister killed. One important feature of a conspiracy charge is that it relieves prosecutors of the need to prove the particular ''roles'' of conspirators. If two persons plot to kill another (and this can be proven), and the victim is indeed killed as a result of the actions of either conspirator, it is not necessary to prove with specificity which of the conspirators actually pulled the trigger. (Otherwise, both conspirators could conceivably handle the gun, leaving two sets of fingerprints and then demand acquittals for both, based on the fact that the prosecutor would be unable to prove, beyond a reasonable doubt, which of the two conspirators pulled the trigger.) A conspiracy conviction requires proof that (a) the conspirators did indeed conspire to commit the crime, and (b) the crime was committed by ''an'' individual involved in the conspiracy. Proof of ''which'' individual it was is usually not necessary. It is also an option for prosecutors, when bringing conspiracy charges, to decline to indict all members of the conspiracy (though the existence of all members may be mentioned in an

" And Snowden said it should include strong guarantees of human rights and privacy and ensure that those guarantees are "not enforced through the words of politicians but through the actions of courts." "This means in advance of surveillance, in all cases the government should seek an individualized warrant, and individualized authorization that this surveillance is lawful and appropriate in relationship to the threat that's presented by the police," he said.
