Privacy notice: Ashton Chantrielle

8 New Square Intellectual Property Chambers (referred to as ‘Chambers’ in this Notice) is a substantial set of chambers specialising in Intellectual Property and related law.  Members of Chambers are all self-employed and in independent practice at the Bar.  Due to the number of specialist barristers in these Chambers, individual barristers are often instructed on opposite sides in litigation.  Members of Chambers and Chambers staff are fully cognisant of the duty to keep the affairs of each client confidential and to manage conflicts of interest properly (Core Duty 6 of the Bar Standards Board’s Handbook and rC89.5).

This Privacy Notice concerns the data protection responsibilities of Ashton Chantrielle, barrister (referred to as ‘I’, below) of 8 New Square Intellectual Property Chambers and principally in connection with instructions from you to that individual. You may also have dealings with Chambers as a collective whole, in which case the data protection responsibilities of Chambers are set out in a separate document entitled ‘Privacy Notice – Chambers’, available on Chambers website at

Please read the following information carefully. This privacy notice contains information about the information collected, stored and otherwise processed about individuals and the reasons for the processing.  It also tells you who I share this information with, the security mechanisms I have put in place to protect information about individuals and how to contact me in the event you need further information.

Who am I?

I, Ashton Chantrielle am a member of Chambers who carries on my practice and other professional activities from my chambers at 8 New Square, Lincoln’s Inn, London, WC2A 3QP.  I may be contacted at the above address, through my Data Protection Manager (DPM), Harri Gibson, at 020 7405 4321 or by email . I am the Data Controller for all personal data that I collect, process and use about you and am responsible for the security of this data under the UK General Data Protection Regulation (“the GDPR”) and the Data Protection Act 2018 (“the DPA”).  Some of your personal data may be processed on systems operated by chambers or by clerks or other employees of Chambers, in which case Chambers will act as Data Processor on my behalf as Data Controller.

For whom is this Privacy Notice intended?

In my practice, I mainly advise and act for companies (in which term I include other corporate bodies). When a company instructs me, I am often provided with personal information about employees, directors or other individuals associated with the client company.   However, it is not appropriate to notify such individuals that I am acting for the client company particularly, for example, where I am advising a company on its rights as against an employee or where an employee is not sufficiently senior to be involved in the matter in relation to which I am instructed.

Therefore when I am instructed by a company, I will normally process information about individuals associated with the company (as well as information about other individuals involved in the case or the matter on which I am asked to advise) on the basis that I am entitled in law to process the information because it is necessary for legal proceedings, providing legal advice, or otherwise for establishing, exercising or defending legal rights.  Where the information is non-sensitive, I may also process it on the basis that the processing is for the legitimate interests of my client, myself or another person.

In some cases I am instructed by a client who is an individual.  If you are such a client, then this Notice is intended for you.  In addition, my clients who are companies may choose to make this Notice available to individuals connected with them.  If you have received this Notice in that way, it explains how I will make use of your personal information.

What do I do with your information?

How I use personal information: Purposes

Whether information has to be provided by you, and why

If I have been instructed by you or on your behalf on a case, your personal information has to be provided, to enable me to provide you with advice or representation and to enable me to comply with my professional obligations, and to keep accounting and other records.

The legal basis for processing personal information

I rely on the following as the lawful bases to collect and use personal information:

  • In relation to all information including that in categories (g) to (o) above (these being either special category data or criminal offence data under the GDPR which are both subject to special rules), I am entitled by law to process the information where the processing is necessary for legal proceedings, legal advice, or otherwise for the establishment, exercise or defence of legal rights, for the administration of justice, or for the publication of legal judgments.
  • In relation to information which is not in categories (g) to (o) above, I rely on my legitimate interests and/or the legitimate interests of a third party in carrying out the processing for the purposes set out above.
  • If you have consented to the processing of your personal information, then I may also process your information for the purposes set out above to the extent to which you have consented to me doing so. Where you have provided such consent, you have the right to withdraw it at any time.
  • If you are a client or otherwise contracting with me or an organisation I work with and the data in question is not special category or criminal offence data, processing is necessary for the performance of a contract (including a contract for legal services) or in order to take steps at your request prior to entering into a contract.
  • In certain circumstances processing may be necessary in order that I can comply with a legal obligation to which I am subject (including carrying out anti-money laundering or terrorist financing checks or complying with obligations imposed on me by professional regulators).
  • In some cases the processing is necessary to publish judgments or other decisions of courts or tribunals.
  • In some cases the processing is necessary to prevent or detect unlawful acts where it is in the substantial public interest and it must be carried out without consent so as not to prejudice those purposes.

With whom will I share personal information?

If you are a client, some of the information you provide will be protected by legal professional privilege unless and until the information becomes public in the course of any proceedings or otherwise.  As a barrister I have an obligation to keep your information confidential, except where it otherwise becomes public or is disclosed as part of the case or proceedings.

It may be necessary to share personal information with the following:

  • information processors, such as such as my Chambers staff, IT support staff, email providers, information storage providers and telephone service providers
  • legal professionals (including solicitors, patent attorneys, trade mark attorneys, mediators, arbitrators and other lawyers and their employees and agents), including those acting for other parties
  • experts and potential experts (including IT specialists and other specialists instructed in relation to litigation, whether or not intended or required to give evidence), witnesses and potential witnesses
  • courts, tribunals and their staff
  • regulatory or administrative authorities
  • my Chambers’ staff
  • pupil barristers, mini pupils or others carrying out placements or work experience in accordance with Chambers’ confidentiality policies
  • my lay and professional clients
  • the general public in relation to the publication of legal judgments and decisions of courts and tribunals
  • In the event of a complaint with the Head of Chambers or Complaints committee
  • Prospective employers, professional or regulatory bodies

I may be required to provide personal information to regulators, such as the Bar Standards Board, the Financial Conduct Authority or the Information Commissioner’s Office. In the case of the Information Commissioner’s Office, there is a risk that personal information may lawfully be disclosed by them for the purpose of any other civil or criminal proceedings, without my consent or the consent of the individual concerned, and this can include privileged information.  I may also be required to disclose your information to the police or intelligence services, pursuant to a court order, or otherwise where required or permitted by law.

Transfer of your information outside the UK

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 UK in any particular case or for a reference. In summary, there are a number of circumstances in which your personal data may be transferred outside the UK:

  • If you reside outside the UK and it is necessary to communicate with you;
  • If your case involves persons or organisations or courts and tribunals outside the UK; or
  • If the nature of the processing is such that we are required to communicate with another person outside the UK about you (for example, a reference you have asked us to send for a role outside the UK).
  • If your data is processed and stored in any cloud storage outside of the UK.

I am satisfied that any such data transferred is fully protected and safeguarded as required by the UK-GDPR, the EU-GDPR and any other relevant data protection regulation.

I may temporarily take personal information outside the UK, for example when travelling for a case or for other purposes, and when it is or appears likely to be necessary to access or have available the information in order to deal with the case to which it relates. When I do this, the information will be retained under my own control, will be subject to adequate safeguards, and the rights of data subjects under United Kingdom law will continue to apply.If Chambers or I publish a judgment or other decision of (or information about a public hearing in front of) a Court or Tribunal containing your information then it may be published on a website or in another form which is accessible from anywhere the world.

If you would like any further information please use the contact details at the beginning of this document.

How long will I store personal information?

I will retain your personal data while you remain a client unless you ask me to delete it. I will delete or anonymise your information at your request unless:

  1. There is an unresolved issue, such as claim or dispute;
  2. We are legally required to retain the data to meet out legal, statutory and regulatory obligations;
  3. There are overriding legitimate business interests, including but not limited to fraud prevention and protecting clients’ safety and security.

I may store personal information:

  • Until at least 15 to 16 years after the case was worked on or another date relevant to the limitation period beginning to run, for example, the date on which the last item of work was done, the date of the last payment made or received or the date on which all outstanding payments are written off, whichever is the latest. That is because 15 years is the long-stop period preferred by the Bar Mutual Indemnity Fund in the light of potential limitation periods.
  • At this point further retention will be reviewed and systems are under consideration to review the information (including historical information held at the time this notice is published) and mark it as appropriate for deletion or reduction in live systems and/or deletion, or archiving into secure encrypted archives or retention for a further period. The timing of moving to such an archive and subsequent deletion from the archive will be considered when I retire from practice.
  • The suitable period may have to be extended depending on the type of information involved. For instance
    • clients sometimes return for advice about copyrights (which may last for the author’s life plus 70 years), trade marks rights (which may last indefinitely), design rights (which may last for 25 years after the registration was applied for) or patent rights (which may last for 20 years and, in the case of a supplementary protection certificate, more than 20 years after the patent application was filed) many years after initial advice was requested or instructions provided,
    • clients sometimes require or request conflict checks to be carried out across Chambers from since members started practicing, and
    • information may be needed for potential legal proceedings in which the limitation period may be alleged not to have started to run until alleged damage or some other event occurred sometime after advice was given or instructions acted upon.
  • Judgments, orders, pleadings and documents drafted by myself or other barristers or lawyers which record or are examples of legal analysis, research, legal practice and other background may be kept while I remain in practice because of the valuable archive of learning which they represent. This will be subject to regular review and assessment of risk having regard to the nature of the information, for instance when data protection policies are regularly reviewed.
  • Information which is retained for the purpose of checking for conflict of interests will be retained for the rest of my career.


As explained above, in most circumstances I will process personal information without seeking or requiring consent from the individual involved, including special category personal data (for example, information about your physical or mental health, racial or ethnic origin, political opinions, sexual orientation, or other sensitive data).  If you are a client who is an individual and have provided your consent to the processing of your personal data when you agreed that I would provide legal services for you, you have the right to withdraw this consent at any time, but this will not affect the lawfulness of any processing activity carried out prior to you withdrawing your consent.  Nor will it prevent the continued processing of your information, where I also rely on other bases for processing your information.

If there is an issue with the processing of your information, please contact me using the contact details above.

Your rights as a data subject

Under the GDPR, you have a number of rights that you can exercise in certain circumstances. These are generally free of charge but may be subject to a reasonable administration fee, in particular if the request is manifestly unfounded or excessive or if further copies of the data are requested after a request.

In summary, you may have the right to:

  • ask for access to your personal information and other supplementary information;
  • ask for correction of mistakes in your information or to complete missing information I hold on you;
  • ask for your personal information to be erased, in certain circumstances;
  • receive a copy of the personal information you have provided to me or have this information sent to a third party. This will be provided to you or the third party in a structured, commonly used and machine-readable format, for example a Word file;
  • object at any time to processing of your personal information for direct marketing;
  • object in certain other situations to the continued processing of your personal information;
  • restrict the processing of your personal information in certain circumstances.

Please however note that I will not normally be able to provide access to personal information where it is covered by legal privilege.  This means that unless you are an individual who has instructed me, it will often not be possible for me to comply with requests for access to your personal data.  However, any requests made to me will be carefully considered and will be responded to in accordance with the law.

If you want more information about your rights under the GDPR please see the Guidance from the Information Commissioner’s Office on Individuals’ rights under the GDPR.

If you want to exercise any of these rights, please:

  • Use the contact details at the beginning of this document;
  • I may need to ask you to provide other information so that you can be identified;
  • Please provide a contact address so that you can be contacted to request further information to verify your identity;
  • Provide proof of your identity and address;
  • State the right or rights that you wish to exercise.

I will respond to you within one month from when Chambers receives your request.

How to make a complaint?

The GDPR also gives you the right to lodge a complaint with the Information Commissioners’ Office if you are in the UK, or with the supervisory authority of the Member State where you work, normally live or where the alleged infringement of information protection laws occurred. The Information Commissioner’s Office can be contacted at

I do not intend to process your personal information except for the reasons stated within this privacy notice.  If this changes, this privacy notice will be amended and placed on the Chambers’ website at:
