Jurors at Southwark Crown Court have been read significant amounts of correspondence between Robert Venables KC and HMRC. Having only just been sent copies the mouseinthecourt has made an editorial decision to publish all 121 pages of it, subject to minor redactions.

With complaints about “menacing” letters, allegations of “bullying tactics”, and references to potential defamation claims. We’ve published the documents and highlighted key passages from the trial below:

Pages 1 – 4
RV complains that a previous request for documents was in fact a “fishing expedition“:

And a complaint was made that the purpose of the enquiries was “simply to harass taxpayers…“:

Venables said he would “like to consider myself a person or more than average fortitude in dealing with over-zealous civil servants” having “asked myself what the effect of such a letter would have been on a less robust person. I shudder to think

Complaint was made over the labelling of correspondence as ‘private’, having asserted that a member of his staff had read a letter from the revenue “avidly“. A veiled threat of a defamation suit was made:

The nub of the defence is also alluded to:

Pages 8 – 9

Further complaint is made of the labelling of envelopes:

The recipient at HMRC is “respectfully” reminded that a breach of confidentiality is a criminal offence.

The tone of the previous letter, sent by HMRC, is criticised as “menacing” and “clearly designed to intimidate“:

Page 18

Venables says the tone of a previous letter, sent by HMRC, is “unnecessarily confrontational” and that HMRC’s assertion that “non-compliance with the notice may render me liable to penalties… does seem heavy handed“.

Page 26

HMRC reply referring to the complaint about the tone of the letter, asking Venables to “accept my apologies for any mis-understanding in this regard“.

Pages 36 – 39

Venables explains to the HMRC investigator that “the difficulty is not so much in explaining the position as in explaining it succinctly and to someone such as yourself who, so far as I know, has no legal qualification“.

A lengthy explanation is given on the next page on the history of trusts, and how the Chancery Division of the High Court was formed. We’re told income tax was introduced “during the Napoleonic wars

An anecdote was given about how “The presiding judge [of a constitution of the Court of Appeal] went out of his way to be rude to me and said that my submissions were as outdated as Gilbert and Sullivan” before the House of Lords “unanimously reversed” the decision and “went out of their way to say how much they had appreciated and relied on my historic analysis“.

Page 64

In a letter dated 7th July 2021 Mr Venables is formally accused of having “committed the offences of fraudulent evasion of income tax…” and is invited to a so-called voluntary interview.

Voluntary in so far as he is warned that he might be arrested were he fail to attend:

Pages 66 – 77

Four-days later Venables replies saying he found the letter “most surprising, not to say “shocking”“. We’re told he “utterly repudiate the allegations which have been made“.

Venables sets out some “basic facts” in case “this letter is put before one of Her Majesty’s Judges” and also “should it be necessary for me to bring proceedings for damages on account of the unlawful action of anyone within HMRC

Venables goes on to explain how he considered himself to be in the company of “some Very distinguished lawyers” including Sir Keir Starmer (who had become leader of the opposition the year before).

Venables refuses to attend the interview, and says he would only consider attending when provided with the “full particulars of the precise criminal conduct in which someone believes I have been engaged and make out that there is a real case for me to answer, in order to justify my wasting considerable time and incurring the considerable expense of engaging the services of a solicitor to represent me and attend the interview“.

With regards to the “implicit threat of arrest” he says HMRC officials might face prosecution for false imprisonment were he to be detained. Reference is made to “less fortunate nations on this earth” where this could be considered lawful.


Damages wouldn’t only be compensatory, but might also be “exemplary“, the letter states:

Whether the letter attracted qualified privilege, a defence in defamation claims, is a matter for another day, we’re told:

Venables accuses HMRC of “bullying tactics” but declines to provide his “unflattering” words:


Despite the misgivings Mr Venables did attend an interview on 24th July 2021. We hope to publish the transcript of the interview in due course.

Page 106

In a letter from HMRC dated 21st June 2022 Venables is invited for second interview. Again, we hope to publish the transcript of the interview in due course.

Pages 108 – 121

Following the second interview, a ‘Memorandum’ is sent to HMRC. In it Venables is critical of those who interviewed him:


The trial continues.
