I was born and raised in Jersey in the Channel Islands. After attending Jersey College for Girls, I completed my law degree and legal practice course at the University of Sheffield, returning to the Island in 2005, where I began my legal career in the commercial dispute resolution department at Appleby. I worked my way from legal assistant to senior associate and I was sworn in as a Jersey Advocate in 2010. In 2016, I joined leading boutique employment and data protection firm Callington Chambers, where I was a partner.
I commenced practice as a specialist sole practitioner in 2019 because I wanted to create a law firm that does things differently. Every case and each client are unique, and by continuing to focus on my specialist areas of data protection, freedom of information, mental health and dispute resolution I can offer expert, focused advice in those areas. People are at the heart of everything I do.
I am keen to support student lawyers and am on the Board of Examiners for the local Advocates and Solicitors examinations and a trustee for the Institute of Law Endowment Trust.
I have worked in the field of information law for some 14 years and been involved in some of the most interesting and ground-breaking cases in this area. I deal with the full spectrum of issues, both non-contentious and contentious and I am ranked as a leading individual by the Legal 500, specifically for my work in this area.
I’ve worked with clients to ensure that their policies, procedures and third-party contracts can demonstrate compliance with relevant data protection legislation, and I’ve drafted notices to meet the required standards of transparency. I’ve advised clients who have suffered significant data breaches (including working with foreign lawyers where there are cross-jurisdictional and insurance elements), carried out data audits and represented data subjects whose data has been compromised, including helping to secure compensation for those individuals.
I have acted for those in the public and private sector including law firms, health establishments, charities, trust companies and regulators.
I am regularly invited to speak at conferences and also provide in-house training for organisations, on request.
I am passionate about the field of mental health and was one of the very first local lawyers to receive accreditation from the Law Society of Jersey to represent individuals detained in hospital under local mental health legislation. I have also been involved in several ground-breaking cases following the implementation of the Capacity and Self-Determination (Jersey) Law 2016 acting either for incapacitated individuals or appointed as amicus curiae by the Royal Court, including in the case of Re B  JRC 150A, where the court made findings relating to an individual’s lack of capacity to consent to sexual relations, contact and residence.
On 1 January 2021 I was appointed Deputy Chair of the Mental Health & Capacity Review Tribunal for a five-year term, determining appeals regarding detention for assessment, detention for treatment, transfers off-island and reviewing authorisations whereby an individual is subject to significant restrictions on their liberty.
In addition to this, I have practised in personal injury for many years (acting for Plaintiffs and Defendants) and have a unique blend of expertise, particularly in respect of psychiatric injury in an employment context and mental health matters generally.
I also served for 4 years as a legal member of the Criminal Injuries Compensation Board.
During the first 11 years of practice, I worked on many diverse local and cross-border commercial and civil litigation matters, including in respect of bankruptcy and insolvency, insurance and general regulatory matters.
I also practise in the field of employment law primarily focusing on contentious employment data protection matters and psychiatric workplace injuries, and am recommended by the Legal 500.
Davida is one of the Island’s best lawyers for information rights legislation and mental health. She is extremely easy to deal with, and always looks at matters with compassion, practicality and pragmatism. Her attention to detail is second to none. 
Davida is a unique and talented professional. Her blend of honesty, warmth, humour, and – most importantly – employment law knowledge is exemplary. She has the ability to think on her feet with logical and realistic arguments and doesn’t bog down clients with overly-legal and technically complex talk. Davida was down-to-Earth, pragmatic, and engaging. 
Davida is knowledgeable and approachable. She is able to demystify and break down a subject that even for lawyers can be difficult to understand. At all times, she was accessible and quick to respond. Her advice was sensible, commercial and pragmatic and her drafting was excellent. She understands how the regulator works and thinks and is able to approach matters accordingly. I wouldn’t hesitate to instruct her again or recommend her to others. 
Data protection expert Advocate Davida Blackmore’s ‘friendly demeanour and approachable nature makes trying situations much easier to deal with. 
Advocate Blackmore is unique in the fact that she was always able to explain key areas we required advice for in a pragmatic yet simple way. She was able to adapt her language to be high level or layman’s terms dependent on who needed to understand. We felt very secure in her hands.

I’m an Advocate of the Royal Court of Jersey. I’m based in Jersey and I provide specialist legal services (predominantly litigation) in the field of information law (data protection, freedom of information, defamation etc.). I also deal with mental health and capacity matters and personal injury and general civil litigation matters. More information about me and my background can be found here.
This privacy notice (Notice) explains the various ways in which I obtain, hold, use and disclose personal data. This Notice also explains what your rights are in relation to any personal data about you that is processed by me.
Any questions in relation to this Notice should be directed to firstname.lastname@example.org.

THE DATA I COLLECT
I process data in order to provide legal services. The type of information I collect includes:
I will usually collect most information from you. However, I may also collect information from:
PURPOSES OF PROCESSING

To meet all applicable legal, regulatory and ethical obligations
My legitimate interests as a provider of legal services to process data to the extent necessary to ensure I meet all legal, regulatory and ethical obligations
I may (depending on the nature of our engagement) need to process what is known as “Special Category Data”. This is information which is generally deemed to be particularly sensitive and includes information on a person’s race, ethnic origin, political opinions, religious or philosophical beliefs, trade union membership, genetic or biometric data processed for the purpose of uniquely identifying a natural person, health data, data on a person’s sex life or sexual orientation or data relating to a person’s criminal record or alleged criminal activity. When I process this information, it will usually be because it is necessary for compliance with a legal obligation or the purposes of legal proceedings or legal advice and because I need it in order to provide you with that advice.
WHO DO I SHARE DATA WITH?
I will never sell your information or pass it to any third party for marketing purposes or for any other purpose unconnected with my business.
I may need to share some of the above information with other parties such as:
Where I enter into an engagement with a third party pursuant to which data may be processed by that third party, I will impose contractual obligations on them to ensure that they are only allowed to use your information to complete the tasks I have asked them to carry out and that they take appropriate measures to protect your personal data.
I may also disclose your personal data to third parties:
Other than as set out above, and save insofar as is necessary in order for me to carry out my obligations arising from any contracts entered into between you and me, I will not share your data with third parties unless I have procured your express consent to do so.
I do not intend to transfer any personal data to jurisdictions outside of Jersey the EU, EEA or UK or to any third countries unless either required to do so by law, or it is necessary for the purposes of my providing you with legal services (such as obtaining relevant legal advice from a foreign jurisdiction). I will always discuss any such transfers with clients prior to transfer.
I take appropriate measures to ensure that any personal data are kept secure, including security measures to prevent personal data from being accidentally lost, or used or accessed in an unauthorised way. I limit access to your personal data to those who have a genuine business need to know it. Those processing your information will do so only in an authorised manner and are subject to a duty of confidentiality.
I also have procedures in place to deal with any suspected data security breach. I will notify you and any applicable regulator of a suspected data security breach where I am legally required to do so.
Unfortunately, the transmission of information via the internet is not completely secure. Although I will do my best to protect your personal data, I cannot guarantee the security of your data transmitted to my website; any transmission is at your own risk. Once I have received your information, I will use strict procedures and security features to try to prevent unauthorised access.
WHERE I STORE YOUR PERSONAL DATA
All information I hold about you is stored on secure systems provided by my third-party service provider within the EEA.
HOW LONG DO I KEEP YOUR INFORMATION?
I retain personal information for the period reasonably necessary for the purpose for which it was collected. In particular:
I store all personal information collected in connection with services that I provide to my clients, e.g. emails that I exchange with you that contain instructions or information required for me to perform services, for so long as the relevant client remains a client of the firm, and for a reasonable period thereafter to enable me to resolve any disputes, enforce my rights, respond to queries, and perform services for the relevant client in the future.
Please note that I am obliged to keep client data for 11 years after the last material entry on the relevant file, this in accordance with the rules of the Law Society of Jersey.
Under data protection legislation, you have various rights in connection with any personal data about you that is processed by me as data controller. These include rights to:
Further information on those rights can be found on the website of the Jersey Data Protection Authority: www.jerseyoic.org.
If you would like to exercise any of those rights, please call, email (firstname.lastname@example.org) or write to me providing enough information to allow me to identify you. It would also be helpful if you could let me know the information to which the request relates. I may require formal proof of identity (photo ID and recent utility bill) and where I request this I must receive it before I am obliged to respond to your request.
CONSEQUENCES OF FAILING TO PROVIDE DATA AND KEEPING INFORMATION UP TO DATE
If you are a client and you do not provide information I need or you ask me to cease processing or erase your data, then the effect may be that I am then unable to provide legal services to you.
If your personal details change, please email me and I will endeavour to update your personal data within seven working days.
RIGHT TO LODGE A COMPLAINT
