Introduction
A persistent misunderstanding in the Gary McKinnon case is that the courts determined the truth of the United States’ allegations that he deliberately damaged military computer systems. They did not. McKinnon admitted gaining unauthorised access to US government computers, but he denied intentionally deleting critical files or causing the extensive operational disruption alleged by prosecutors. Because the extradition proceedings ended before any criminal trial took place, the prosecution’s separate claims about deliberate damage, outages and financial loss were never tested through the normal adversarial process required to establish guilt beyond reasonable doubt.[UK Parliament]publications.parliament.ukUK Parliament House of LordsUK ParliamentHouse of Lords - Mckinnon V Government of The United States of America and AnotherJuly 30, 2008…
This distinction is important. The extradition courts examined whether the legal requirements for surrendering McKinnon to the United States had been met, not whether every factual allegation in the indictments had been proved. When the UK Home Secretary ultimately blocked extradition on human rights grounds in 2012, no US trial occurred, and no UK prosecution followed. As a result, the allegations of damage remain allegations rather than judicial findings.[Hansard]hansard.parliament.ukHansard ExtraditionExtradition - Hansard - UK Parliament…
What the extradition courts accepted
The British courts treated the American indictments as the basis for deciding whether extradition was legally justified. They summarised the prosecution’s case, including allegations that McKinnon accessed 97 government computers, deleted operating-system files, erased user accounts, disrupted networks and caused losses running into hundreds of thousands of dollars. However, recording those allegations was not the same as deciding they were true.[UK Parliament]publications.parliament.ukUK Parliament House of LordsUK ParliamentHouse of Lords - Mckinnon V Government of The United States of America and AnotherJuly 30, 2008…
Extradition proceedings serve a narrower purpose than a criminal trial. They address questions such as:
- whether the alleged conduct would amount to an offence in both jurisdictions;
- whether the legal requirements for extradition have been met;
- whether extradition would breach applicable legal protections, including human rights.
They are not designed to resolve disputed technical evidence or determine criminal liability beyond reasonable doubt. Accordingly, the House of Lords noted McKinnon’s admissions of unauthorised access while distinguishing them from the prosecution’s allegations of deliberate damage, which he had not admitted.[UK Parliament]publications.parliament.ukUK Parliament House of LordsUK ParliamentHouse of Lords - Mckinnon V Government of The United States of America and AnotherJuly 30, 2008…
What a criminal trial would have tested
Had McKinnon been tried in the United States, prosecutors would have had to prove much more than unauthorised access.
A contested trial would likely have examined several factual questions that remained unresolved:
- Whether the deletions were intentional. Prosecutors alleged deliberate removal of operating-system files, user accounts and logs. The defence would have been entitled to challenge both the forensic evidence and the interpretation of system events.
- Whether McKinnon’s actions directly caused the outages. Military networks can fail for multiple reasons, and a jury would have had to assess whether the prosecution had proved a causal link between specific acts and the reported disruption.
- How financial losses were calculated. The widely cited damage figures included restoration work, security reviews, forensic investigation and system recovery costs. A trial could have examined whether every claimed expense was legally attributable to McKinnon’s conduct under the relevant computer crime statutes.
- The reliability of digital forensic evidence. Witnesses could have been cross-examined on logs, timestamps, recovered files and attribution evidence, while defence experts could have challenged the prosecution’s technical conclusions.
Those are precisely the kinds of disputed factual issues that criminal trials are designed to resolve but extradition hearings are not.[UK Parliament]publications.parliament.ukUK Parliament House of LordsUK ParliamentHouse of Lords - Mckinnon V Government of The United States of America and AnotherJuly 30, 2008…
Why the allegations were never judicially resolved
The principal reason is procedural rather than evidential.
After years of litigation, the legal dispute shifted away from the underlying hacking allegations and towards whether extradition would violate McKinnon’s human rights because of his Asperger’s syndrome, severe depression and assessed suicide risk. In October 2012, Home Secretary Theresa May concluded that extradition would create an unacceptable risk to his life and withdrew the extradition order. That decision addressed only the legality of extradition, not his factual guilt or innocence regarding the alleged damage.[Hansard]hansard.parliament.ukHansard ExtraditionExtradition - Hansard - UK Parliament…
Following that decision, the possibility of a UK prosecution was considered. In December 2012, the Crown Prosecution Service decided not to prosecute. Among the factors cited publicly were the location of the principal evidence and witnesses in the United States, together with the passage of time, meaning no criminal court ultimately heard the evidence in full.[UK Parliament Committees]committees.parliament.ukUK Parliament CommitteesEXL0080 - Evidence on Extradition LawNovember 19, 2014…
The consequence was unusual but legally significant: the extradition litigation ended without any criminal court determining whether the prosecution had proved the separate allegations of intentional damage.
How to distinguish allegation from finding
The McKinnon case illustrates an important legal distinction that is often lost in public discussion.
It is accurate to say that:
- McKinnon admitted accessing protected US government computers without authorisation.
- US prosecutors alleged that he intentionally caused extensive system damage and substantial financial losses.
- British courts accepted that those allegations were sufficient to support extradition proceedings under the applicable legal framework.
- No criminal court ever ruled that the damage allegations had been proved beyond reasonable doubt.[UK Parliament]publications.parliament.ukUK Parliament House of LordsUK ParliamentHouse of Lords - Mckinnon V Government of The United States of America and AnotherJuly 30, 2008…
Conversely, it is inaccurate to describe the alleged deletions, outages or monetary losses as judicially established facts. They remained part of the prosecution’s case because no completed criminal trial gave the defence the opportunity to challenge the evidence through cross-examination, competing expert testimony and jury determination.
The unresolved status of those allegations helps explain why the McKinnon case continues to generate debate. One side points to detailed indictments describing extensive operational harm, while the other emphasises that those claims were never subjected to the evidential testing that a criminal trial is intended to provide. Both positions can be acknowledged without confusing an accusation made in support of extradition with a finding reached after conviction.[UK Parliament]publications.parliament.ukUK Parliament House of LordsUK ParliamentHouse of Lords - Mckinnon V Government of The United States of America and AnotherJuly 30, 2008…
