The Fraudulent Mediums Act 1951 was the British law that replaced the Witchcraft Act of 1735, making it an offence to pose as a medium or clairvoyant for money with intent to deceive, while leaving genuine believers and entertainers alone. Passed after a long Spiritualist campaign and the notorious wartime trial of the medium Helen Duncan, it was itself repealed on 26 May 2008, when general consumer-protection regulations took over the regulation of paid psychic services.

Before 1951: The Witchcraft Act and the Vagrancy Act§

By the twentieth century British law no longer treated witchcraft as a real crime. The Witchcraft Act of 1735, which came into force in 1736, had repealed the old statutes under which witches had been hanged, and replaced them with an offence of pretending to exercise witchcraft, sorcery, enchantment or conjuration, to tell fortunes, or to use occult skill to find lost or stolen goods. The law now presumed that such powers did not exist and punished the claim to them as an imposture, with up to a year's imprisonment. For the earlier period of capital prosecutions, see our article on the European witch trials.

A second weapon was the Vagrancy Act of 1824. Its fourth section classed as a "rogue and vagabond" anyone pretending or professing to tell fortunes, or using any subtle craft, palmistry or other device to deceive. Palmists, astrologers, crystal-gazers and Romani fortune-tellers were prosecuted under it throughout the nineteenth and early twentieth centuries, and it was also turned against mediums, most famously the American slate-writing medium Henry Slade in London in 1876, whose conviction was overturned on appeal on a technical point.

For the Spiritualist movement, which had grown in Britain since the 1850s and was strengthened by the mass bereavement of the First World War, these laws were a long-standing grievance. Spiritualists regarded mediumship as a religious gift, comparable to prayer or prophecy, and argued that laws written for vagrants and witches branded honest practitioners as frauds. Between the wars they lobbied repeatedly for change, without success. The wider story of the movement is told in our guide to Spiritualism.

Helen Duncan and the Last Witchcraft Act Trials§

The case that made reform unavoidable was that of Helen Duncan (1897–1956), a Scottish materialisation medium who held séances in which spirit forms were said to appear wrapped in "ectoplasm". Investigators in the early 1930s had already concluded that her ectoplasm was cheesecloth, and she had been convicted of fraud in Edinburgh in 1933.

In January 1944 police raided one of her séances in Portsmouth, the home of the Royal Navy, after a naval officer reported his suspicions. Duncan and three associates were eventually tried at the Old Bailey in March and April 1944 on charges that included conspiracy to contravene the Witchcraft Act, and she was sentenced to nine months' imprisonment. Many Spiritualists believed she had been targeted for security reasons, citing a story that she had revealed the loss of the battleship HMS Barham, sunk in November 1941, before it was officially announced. The historian Malcolm Gaskill, who studied the case in detail, found the episode better explained by wartime anxieties, local policing and long-standing suspicion of her mediumship than by a deliberate government plot, though the Barham story remains part of her legend.

The use of a 1735 statute in a modern court drew ridicule. Winston Churchill is reported to have asked the Home Secretary to explain why the Act had been used and what the trial had cost, describing it as obsolete. Later in 1944 another medium, Jane Rebecca Yorke, was convicted under the same Act and fined; she is usually described as the last person convicted under it. Duncan herself died in 1956, weeks after another police raid on a séance in Nottingham, and her supporters have since campaigned, so far without success, for a posthumous pardon.

The Fraudulent Mediums Act 1951§

After the war the Spiritualist lobby found a parliamentary champion in the Labour MP Thomas Brooks, himself a Spiritualist, who introduced a private member's bill to replace the old law. It received Royal Assent in June 1951 as the Fraudulent Mediums Act.

The Act did three main things:

  1. It repealed the Witchcraft Act of 1735, removing the last statute in Britain that named witchcraft and conjuration.
  2. It created a narrower offence. A person committed a crime if, with intent to deceive, they purported to act as a spiritualistic medium or to exercise powers of telepathy, clairvoyance or similar powers, or used a fraudulent device while doing so. Crucially, the prosecution had to prove that the defendant acted for reward, and anything done solely for entertainment was exempt.
  3. It removed mediums and clairvoyants from the fortune-telling clause of the Vagrancy Act, so that they could no longer be treated as rogues and vagabonds.

Proceedings in England and Wales required the consent of the Director of Public Prosecutions, and the maximum penalties were a fine or a short prison term on summary conviction, or up to two years' imprisonment on indictment. In effect, the law stopped treating the claim to communicate with spirits as fraudulent in itself. It became an offence only when a paid practitioner deliberately set out to deceive.

Spiritualists welcomed the Act as a recognition of their religious freedom. The repeal of the Witchcraft Act had another, unintended consequence: it removed a legal obstacle to the public revival of witchcraft as a religion. Gerald Gardner's Witchcraft Today appeared in 1954, and historians often connect the timing of modern Wicca's emergence with the 1951 change, as described in our article on Wicca and Gerald Gardner.

Mediums and Psychics Under the 1951 Act§

In practice the Fraudulent Mediums Act was rarely used. The requirement to prove intent to deceive was a high bar: a medium who sincerely believed in her gift could not be convicted however inaccurate her messages, and few cases reached court in the Act's fifty-seven years. Police and prosecutors generally preferred to pursue blatant frauds, such as people who extracted large sums from the bereaved, under the ordinary law of deception and theft.

The business it regulated was nonetheless transformed. Spiritualist churches continued to hold demonstrations of clairvoyance, but alongside them grew a commercial psychic industry of stage mediums, telephone psychic lines, television channels and, later, websites. Organisations such as the Spiritualists' National Union developed their own training for mediums, partly to distinguish their members from commercial operators, while sceptics argued that the Act's narrow wording left vulnerable people unprotected. The scientific and investigative background to these debates is discussed in our article on clairvoyance and psychical research.

Repeal in 2008: Consumer Protection Replaces the Mediums Act§

The Fraudulent Mediums Act was repealed by the Consumer Protection from Unfair Trading Regulations 2008, which came into force on 26 May 2008. The regulations implemented the European Union's Unfair Commercial Practices Directive of 2005 and replaced a patchwork of older laws with general rules against unfair, misleading and aggressive commercial practices.

The change moved paid mediumship from criminal law about spirits to ordinary consumer law. Mediums, psychics, astrologers and tarot readers who charged for their services became traders like any other, answerable to trading standards officers. The directive specifically protected consumers who are particularly vulnerable because of mental or physical infirmity, age or credulity, a category that critics of the psychic industry thought especially relevant to grieving clients.

Some Spiritualists and mediums voiced concern that the new regime could expose honest practitioners to complaints from dissatisfied customers, since a medium cannot prove that a message really came from the dead. In response, many practitioners adopted standard disclaimers stating that readings are offered for entertainment or experimental purposes, that results cannot be guaranteed and that clients must be adults. In April 2025 the 2008 regulations were themselves superseded by the consumer provisions of the Digital Markets, Competition and Consumers Act 2024, which continue the same general principles.

Psychics, Mediums and the Law Elsewhere§

Britain was not alone in revising old laws on fortune-telling and pretended magic. Canada's Criminal Code contained an offence of pretending to practise witchcraft, sorcery or fortune-telling, inherited from English law, until it was repealed in 2018. In the United States, regulation is local: New York's Penal Law, for example, still treats fortune-telling for a fee as a misdemeanour unless it is offered for entertainment or amusement, while other states and cities rely on licensing. In the United Kingdom, broadcasting rules require that demonstrations of the paranormal or divination be treated with due objectivity, and that entertainment be clearly labelled as such.

These laws reflect a long historical shift. Early modern statutes punished witchcraft as real harm; the 1735 Act punished the claim to magical power as a lie; the 1951 Act punished only deliberate, paid deception; and the 2008 regulations treated paid spirit communication as a service to be judged by the standards of consumer fairness. Belief itself has long ceased to be the law's concern. As with any paid spiritual service, such readings are no substitute for professional financial, medical or legal advice.

Frequently asked questions§

What was the Fraudulent Mediums Act 1951?§

It was a British statute that repealed the Witchcraft Act of 1735 and made it an offence to pose as a medium, clairvoyant or telepath for reward with intent to deceive, or to use fraudulent devices while doing so. Performances given purely for entertainment were exempt.

When and why was the Fraudulent Mediums Act repealed?§

It was repealed on 26 May 2008 by the Consumer Protection from Unfair Trading Regulations 2008, which implemented an EU directive on unfair commercial practices. Paid psychics and mediums became subject to general consumer-protection law instead of a special criminal offence.

Was Helen Duncan the last person convicted under the Witchcraft Act?§

Helen Duncan's 1944 trial is the most famous Witchcraft Act case, but later that year the medium Jane Rebecca Yorke was also convicted under the Act and is usually named as the last. Duncan's case did more to discredit the old law and to build support for the 1951 reform.

Is it illegal to be a psychic in the UK?§

No. Practising as a medium, psychic or tarot reader is legal. Those who charge for their services are treated as traders and must not mislead or exploit consumers, which is why many advertise their readings with disclaimers.
