Factual and Procedural Background
The claimant, a computer scientist with an interest in cryptocurrencies, asserts that he is the pseudonymous developer of Bitcoin, known as Satoshi Nakamoto, who authored the seminal 2008 academic paper on the cryptocurrency. The defendant, a resident of Oslo with an interest in Bitcoin, disputes the claimant's assertion and has publicly declared the claimant a fraud through various tweets, culminating in a campaign launched on 17 March 2019. The claimant initiated libel proceedings in England and Wales concerning a specific tweet posted by the defendant on that date, alleging it caused serious harm to his reputation.
The defendant applied for summary judgment under CPR rule 24.2, contending the claimant has no real prospect of proving serious harm from the tweet's publication. The claimant opposes this application. The matter has a complex procedural history, including jurisdictional challenges and parallel proceedings in Norway. The claimant has also brought related defamation proceedings against other parties concerning similar defamatory allegations.
Legal Issues Presented
- Whether the claimant has a real prospect of proving that the publication of the tweet caused serious harm to his reputation within England and Wales.
- Whether the defendant's application for summary judgment should be granted pursuant to CPR rule 24.2 on the basis that the claimant lacks a real prospect of success.
- The admissibility and relevance of evidence concerning the claimant's prior reputation, conduct, and other publications in assessing serious harm and causation.
Arguments of the Parties
Defendant's Arguments
- The claimant cannot establish serious harm caused by the publication of the tweet, as the case on serious harm is inferential and lacks evidence of actual impact on readers.
- The defamatory allegation is not "very grave" given the claimant's existing reputation for dishonesty and fraud, including adverse judicial findings and prior conduct.
- The scale of publication within England and Wales was limited, with few followers likely to have read the tweet and no evidence of republication.
- The claimant's pleaded meaning relies on innuendo, and the audience familiar with the claimant's notoriety would not be significantly affected.
- The claimant's prior convictions and adverse findings are admissible as relevant background context and mitigate the alleged harm.
- The claimant's own conduct in 2016, including promises to prove the Bitcoin Claim and failure to do so, is relevant background context.
- Other numerous tweets and publications alleging fraud are relevant to causation and background context, though the defendant accepts the rule in Dingle limits their use in mitigation of damages.
- The claimant's case is an abuse of process and lacks merit.
Claimant's Arguments
- The tweet was part of a targeted campaign to damage the claimant's reputation, constituting a grave defamatory allegation central to his professional reputation.
- The claimant will demonstrate at trial that the tweet was likely read by significant numbers within England and Wales, including through amplification by third parties.
- It is impermissible for the defendant to rely on prior publications or allegations to justify defamatory statements or to claim a pre-existing bad reputation.
- The claimant disputes making promises to prove the Bitcoin Claim and denies authorship of some blog material cited by the defendant.
- There are significant factual disputes about the events of 2016 and the claimant's involvement, which cannot be resolved summarily.
- The claimant challenges the defendant's presentation and completeness of Twitter analytics data and seeks full disclosure to assess the extent of publication.
- The defendant's reliance on prior convictions and adverse findings is irrelevant or inadmissible for the purposes of assessing serious harm.
- The claimant denies the defendant's abuse of process claim and asserts a real prospect of success on the libel claim.

Court's Reasoning and Analysis
The court approached the defendant's summary judgment application by applying the established test under CPR rule 24.2, requiring the defendant to show the claimant has no real prospect of success and that there is no compelling reason for a trial. The court accepted for the purposes of this application the claimant's pleaded meaning of the tweet, recognizing it as a grave allegation striking at the core of the claimant's professional reputation.
On the issue of serious harm under s.1 of the Defamation Act 2013, the court applied the principles clarified by the Supreme Court in Lachaux and subsequent cases, emphasizing that serious harm must be demonstrated by reference to actual or likely impact, not merely the defamatory meaning. The court acknowledged that inferences about harm may be drawn from the evidence reasonably expected at trial.
The court found that the evidence regarding the scale of publication was incomplete and, in some respects, misleading. The defendant had failed to disclose full Twitter analytics data relevant to the period, limiting the claimant's ability to assess the extent of publication and impact. The court stressed the importance of procedural fairness and ordered that the defendant provide full disclosure and facilitate a fair evaluation of data on publication scale and readership.
The court rejected the defendant's reliance on prior convictions and adverse findings as evidence of the claimant's general bad reputation relevant to serious harm, noting their limited relevance and temporal or jurisdictional remoteness. The audit report by the Australian tax authorities was considered administrative and not equivalent to judicial findings, and its relevance remained uncertain pending further evidence.
Regarding the claimant's conduct in 2016 and blog posts, the court noted significant factual disputes and an extensive plea of justification by the defendant, concluding these matters could not be resolved summarily and must await trial.
The court examined the defendant's reliance on other publications and tweets, emphasizing the rule in Dingle which restricts their use in mitigation of damages or to negate serious harm. The court found no principled basis to admit such material as directly relevant background context in this case, given the heavy factual disputes and the absence of a pleaded causal link to specific harm.
Overall, the court concluded that the defendant had not demonstrated that the claim lacked a real prospect of success, particularly given the unresolved factual issues and incomplete disclosure. The claimant's case on serious harm, while not supported by specific examples of actual harm, was realistic and warranted trial consideration.
Holding and Implications
The court DENIED the defendant's application for summary judgment.
This decision means that the libel claim concerning the tweet will proceed to trial. The claimant will have the opportunity to present full evidence on the extent of publication, impact, and serious harm to reputation. The court emphasized the need for full disclosure of relevant Twitter data and a fair evaluation of the evidence at trial. No new legal precedent was established; rather, the court applied existing principles to the facts and procedural posture of this case.
