R v S (2023) (Warwick Crown Court)
Prosecution counsel in a case where the defendant represented herself as an immigration solicitor despite not being registered with the SRA or having OISC authorisation to provide immigration advice. One victim paid over £2000 in “fees” for unregulated advice. Following trial, the defendant was convicted of fraud by false representation (Section 2, Fraud Act  2006) and providing immigration advice when not qualified to do so (Section 84 Immigration and Asylum Act 1999).

R v MM (2022) (Harrow Crown Court)
The defendant was sentenced to 15- and 12-months imprisonment (concurrent) for offences of burglary and being concerned in the supply of Class B drugs respectively, alongside three co-defendants. Initially charged as aggravated burglary, following discussions with the Crown a plea was accepted to the Section 9 offence and a basis of plea was accepted in relation to being concerned. As a result of submissions on the defendant’s age and vulnerability, a further 20% reduction in sentence was applied.

R v TB (2022) (Central Criminal Court)
Represented a defendant charged with murder alongside two co-defendants.  All defendants denied participation in a joint enterprise. Following a four-week trial at the Old Bailey, the Defendant was acquitted of all charges. (Led).

R v Head (2022) (Court of Appeal)
Conviction overturned on appeal to Court of Appeal on basis of fresh evidence prosecution failed to disclose, establishing it is a ‘short step’ from concluding that non-defendant bad character fresh evidence would have been admissible under s100(1)(b) CJA 2003 to satisfying the test for appeal against conviction.

Depending upon the circumstances of the case, the legal bases upon which I process personal data are (i) the performance of a contract to which the data subject is a party or in order to take steps at the request of the data subject prior to entering into a contract, (ii) the processing is necessary to comply with legal obligations to which I am subject, or (iii) the processing is necessary for the legitimate interests set out above, except where such interests are overridden by the interests or fundamental rights and freedoms of the data subjects which require protection of personal data, in particular where the data subject is a child.  When I rely on (iii) legitimate interests, my ‘Legitimate Interests Assessment’ can be found here.  When I process data which has not been obtained directly from the data subject (e.g. personal data contained in evidential materials), it will have been supplied to me as part of my instructions in circumstances covered by legal professional privilege.

Depending upon the circumstances of the case, I may share the personal data with:

  1. my Chambers, which supplies professional and administrative support to my practice;

In cases where there is a contract between me and the data subject, the provision of personal data is a contractual requirement and the data subject is obliged to provide the personal data in order that I can supply legal services.  A failure to provide such data may mean that I will not be able to provide those legal services.
