Que veut dire « Queen’s Counsel » ?
Littéralement « Conseiller de la Reine », c’est un titre honorifique accordé aux avocats les plus expérimentés et spécialisés. Les QCs ne constituent pas un ordre professionnel séparé, mais leur statut, qui remonte au début du 17eme siècle, est conféré par des lettres patentes de la Reine et est reconnu comme un signe d’excellence et de distinction. Souvent en parlant d’un QC on va l’appeler un « Silk ». Ce terme fait référence au fait que, contrairement aux autres avocats, un QC porte une toge en soie quand il plaide.

7. With whom will I share your personal information?
Some of the information I collect as set out above, will be protected by legal professional privilege unless and until it becomes public in the course of any proceedings or otherwise.
As a barrister I also have an obligation to keep personal information confidential and private, except where it otherwise becomes public or its publication or disclosure is necessary as part of the case or proceedings. It may be necessary to share your information with the following: a) clerks, members, mini-pupils, pupils and staff in/of my and other chambers; b) current, past or prospective employers or referees; c) education and examining bodies; d) the general public in relation to the publication of judgments or decisions of courts or tribunals; e) government departments and other public authorities, including investigators,f) ombudsmen, prosecutors and regulators; g) in the event of complaints, my head of chambers, other members of my chambers who deal with complaints, my clerks and chambers director, the Bar Standards Board and the Legal Ombudsman; h) in the event of legal proceedings, my head of chambers, my clerks and chambers director, my insurers and my own legal advisers; i) IT support staff, email providers and data storage providers; j) lay and professional clients and their staff; k) other legal professionals or experts; l) the intended recipient, where you have asked me to provide a reference; m) the members and staff of courts, tribunals and inquiries; n) professional advisers, associations and trade bodies, e.g. Bar Associations, the Bar Council or the Inns of Court; o) witnesses; p) your associates, family and friends or those of my clients.

I may also be required to disclose your information to the police or intelligence services in accordance with my legal or professional obligations.
8. Transfer of your information outside the European Economic Area (“EEA”)
This privacy notice is of general application and as such it is not possible to state whether it will be necessary to transfer your information out of the EEA in any particular case or for a reference. However, if you reside outside the EEA or your case or the role for which you require a reference involves persons or organisations or courts or tribunals outside the EEA, then it may be necessary to transfer some of your personal information to that country outside of the EEA for that purpose. If you are in a country outside the EEA or if the instructions you provide come from outside the EEA, then it is inevitable that information will be transferred to those countries. If this applies to you and you wish additional precautions to be taken in respect of your information, please indicate this when providing initial instructions. Some countries and organisations outside the EEA have been assessed by the European Commission and their data protection laws and procedures have been found to provide adequate protection. Most do not. If your information has to be transferred outside the EEA, then it may not have the same protections and you may not have the same rights as you would within the EEA.
I may transfer your personal information to the following which are located outsidethe EEA: 1. Cloud data storage services based in the USA who have agreed to comply with the EU-U.S. Privacy Shield, in order to enable me to store your data and/or backup copies of your data so that I may access them when I need to. The USA does not have the same data protection laws as the EU, but the EU-U.S. Privacy Shield has been recognised by the European Commission as providing adequate protection.If I decide to publish a judgment or decision of a court or tribunal containing yourinformation then this will be published to the world. I will not otherwise transfer personal information outside the EEA except as necessary for providing legal services or for any legal proceedings.
9. Security measures
Publication of details about my security arrangements would risk their compromise, but my accounts, equipment, premises and records are all backed-up, encrypted, locked, password-protected, secured and/or subject to anti-virus and firewall protection as appropriate and having regard to Bar Council guidance on IT issues
Furthermore, where my chambers acts as a data processor on my behalf it does so in with GDPR-compliant constitutional, contractual, technical and organisational arrangements, policies and procedures and subject to guarantees and obligations of confidentiality. In this regard, the clerks and staff in my chambers and my chambers’ IT support staff provide me with assistance and support and communicate and liaise with others on my behalf and I also use my chambers’ IT systems, including email servers, fee, diary, practice-management and record-keeping software, internet and intranet, network and other shared drives and servers.
10. What is my retention policy with respect to your personal data?
I will normally store your information for a maximum of 25 years from whichever is the latest of: the date of the last item of work carried out by me on the case; the date on which time for any further appeal expired; the date of the last payment received by me; or the date on which all outstanding payments are written off.
Further retention is likely to occur where: a longer limitation period applies (e.g. the case involved a minor); the case involved an order which remains effective, contains an injunction or undertakings to the court and is subject to a penal notice; or connected complaint, legal or regulatory proceedings are active or reasonably in prospect. In such circumstances, I will carry out as much minimisation as is practicable and set a date for a further review on a case by case basis.
Deletion / destruction / minimisation will be carried out (without further notice) as soon as reasonably practicable after the information is marked for this to done.
I will store some of your information which I need to carry out conflict checks for the rest of my career in practice as a barrister. However, this is likely to be limited to your name and contact details, solicitors and outline information relating to the case or instruction.
This will not include any information within categories (2)-(3), (7), (12)-(14) or (16)-(18) at para.2.1 above. Information related to anti-money laundering checks will be retained until five years after the completion of the transaction or the end of the business relationship, whichever is the later.
I am relying on your consent to process your information as set out above. You provided this consent when you agreed that I would provide legal services, you asked me to provide a reference or you applied to be or became a clerk, member, mini-pupil, pupil or staff member in/of my chambers. You have the right to withdraw this consent at any time, but this will not affect the lawfulness of any processing activity I have carried out prior to you doing so. Furthermore, where I also rely on other legal bases for processing your information, you may not be able to prevent me doing so.
12. Your rights
Under the GDPR, you have a number of rights that you can exercise free of charge in certain circumstances. In summary, and subject to certain legislative exemptions and restrictions, you may have the right to: 0a) ask for access to your personal information and other supplementary information; b) ask for correction of mistakes in your data or to complete missing information; c) ask for your personal information to be erased; d) receive a copy of the personal information you have provided to me or have thise) information sent to a third party in a structured, commonly used and machine-readable format, e.g. a Word document file;f) object at any time to processing of your personal information for direct marketing; g) object in certain circumstances to the continued processing of your personal information; h) restrict my processing of your personal information; i) ask not to be the subject of automated decision-making which produces legal effects that concern you or affect you in a significant way (albeit that I do not myself carry out any such decision-making).
