Blackstone Chambers

Training at the set is taken “very seriously”, one junior tells us, with “people being very generous with their time”. Alongside training, “extensive feedback on assessments (whether written or oral)” is also offered, with “transparency as to your improvements across the year”. This is complemented by a two week employment bootcamp hosted by the chambers where more senior members dedicate “a huge amount of their time” to provide a bespoke employment law training course, including running mock case management conferences with live feedback. Inevitably, tenants agree that “the most helpful training you receive is just in the course of your day to day work with your pupil supervisors”.

“I look back at how I have developed over the course of the year and am amazed at my own progress,” one junior tells us, crediting their pupil supervisors. Members also describe their mentors as “invariably wise and lovely people,” reiterating how “seriously” they take their role. Whilst pupillage “can be testing at times,” supervisors are said to be “very empathetic to the challenges” that rookies face. Pupils add that supervisors “succeed” in making the experience as “humane and enjoyable” as possible.

As well as being broad in nature, the work undertaken by members at Blackstone Chambers is “cutting edge” and “often in the newspapers”. This means the work is “hugely challenging” but also often pretty juicy.

Some headline grabbing cases over the past few years include acting for the Duchess of Sussex in her copyright claim against the publishers of the Mail on Sunday and Mail Online, the immigration case involving UK teenager Shamima Begum, and representing the Rugby Football Union in relation to charges brought against Barbarian players for allegedly breaching Covid-19 rules. If those aren’t blockbuster enough for you, two members acted in the copyright and contractual battle over the Star Wars franchise after a filming row broke out at a fan convention shortly before the release of Star Wars Episode VII: The Force Awakens. One member, Ian Mill KC, has even made his way onto the F1 Tribunal judging panel, and is one of only two UK judges.

If there’s a football club that the set hasn’t represented, we certainly haven’t heard of it. Nottingham Forest, Sheffield United, Everton, and Leicester City have all been on the books recently, with Lord Pannick KC now famous for his work for Manchester City (fans even created him a banner!) Other highlights have included acting in the case of a teacher who deliberately misgendered a transgender pupil in the classroom and outed him on national television, and The Duke of Sussex’s recent Mirror Newspapers hacking litigation. Of course that’s all in addition to the multibillion pound disputes and casual appearances in the Supreme Court, The Grand Chamber of the Court of Justice of the European Union, and the European Court of Human Rights. Even at the junior end “you are spoilt for choice”.

With all of this “uniquely interesting, and uniquely challenging” work up for grabs, help is on hand from colleagues, should one require it. One member tells us: “The true distinguishing feature of Blackstone from all other top tier sets: just the most amazing people. It is really like having a professional family.” Another source, who recently arrived from a different set,, says they “felt fully welcomed and included”, and already boasts a long list of senior members they can “regularly pick up the phone to for advice on difficult issues”. As one junior puts it: “Everyone wants you to do well. It’s that simple”. One insider goes as far as to say that the set “genuinely prides itself on being a friendly, inclusive, and collaborative place”, with another adding that the people are “genuinely warm and inclusive”. This is “a real point of difference with rival sets,” we’re told.

When it comes to work/life balance, there are mixed views, though most barristers who say their balance is off do recognise that this is “a personal decision, not a chambers decision”. One member offered this take: “I could have a much better work/life balance, and lots of my colleagues do. I have chosen not to, while I advance my career and explore my options.” Fresh pupils aren’t thrown straight in at the deep end, however. “I assumed I would be working round the clock as a pupil. It was not like that at all. On the whole, pupil supervisors try their hardest to make pupillage a 9am-6pm, Monday-Friday experience” one insider reveals.

Pupils share their experience of assessments also being well structured, usually having time to complete them during “normal working hours.” This is “only possible”, however, “if you are efficient!” Even when juniors are “incredibly busy and overwhelmed” it’s always “with offers of interesting work,” we’re told.

It isn’t all work, work, work though, Blackstone Chambers is a sociable place. Friday night drinks in Middle Temple Gardens are a regular occurrence, as well as summer parties and BBQs. One tenant tells us of the “weekly teas and drinks”, where “big groups of people go to hall together”. One member said “there’s far more than anyone has time to attend…” but “parties are fun and well-attended”. We’ll try and work out if that means there’s too much social or too much work! Lots has been said about the “lovely roof terrace”. One tenant gives a shout out to the events team who do an “amazing job” of hosting “a very full calendar”. On par for a top tier set client events include “breakfast briefings, lunches and dinners, drinks, barbecues on the roof, seminars, sports events”, the list seems endless. As one tenant puts it, “there is always something fun going on”.

In terms of premises, Blackstone Chambers is located within minutes of the Royal Courts of Justice and overlooks Middle Temple Gardens. The set has recently undergone a major refurbishment — one of the most significant building projects completed by any London set — creating a “unique and contemporary new home in historic Middle Temple”. We hear “the new buildings are a 10/10”. They have been designed to integrate the set into a “single-site complex” and a “modern working environment to meet the needs of clients going forward”. An insider calls it “very snazzy, like a modern law firm’s office”, only housed in “beautiful buildings overlooking Middle Temple Gardens”. A lot has also been done in recent years to improve the IT support and technology offering within chambers. A tenant shares the IT is “extremely good”, equivalent to a “global law firm”. One insider stated: “Everything is seamless”. What more could you want?

Blackstone takes on four pupils each year, boasting a hefty award of £90,000, and a high hit-rate for offering tenancy to pupils. Pupillage at Blackstone is completely non-practising — which sadly means no top-up money in addition to the pupillage award — but pro bono and charity work is encouraged during the 12-month training period, alongside a heavy investment into in-house advocacy training. Pupils sit with four different supervisors and gain a grounding in the chambers’ core areas of commercial, public, and employment law. Pupils work solely with each supervisor — something which is somewhat unusual — and typically assist with the drafting of pleadings, skeleton arguments and advices, as well as attending conferences. Pupils are assessed through a rigorous process of written tasks and advocacy exercises. One member commenting on the training provided, says they were “trained by the best in every field” which was a “total privilege”.

Those looking to apply for pupillage should make their application through the Pupillage Gateway. Prospective pupils must complete a mini-pupillage with Blackstone Chambers, and should aim to do this before submitting their pupillage application — otherwise, it will be considered a dual application for both a mini and for pupillage. Those marking the application will focus on academic achievements, legal and non-legal employment, relevant work experience, written and oral advocacy, and written communication skills. Once all mini-pupillages have been completed, the 16 highest scoring candidates across the application and minis will be invited to a final round interview.

Blackstone Chambers states that it is fully committed to diversity and inclusion, and ensures that pupillage offers are made solely on merit. They are proud to participate in COMBAR’s Mentoring Scheme for those from under-represented groups at the Commercial Bar.

The pupillage experience

I chose to come to Blackstone because of the mix of high-quality work on offer. I knew the broad outlines of the types of law I was interested in, but I appreciated that the breadth of Blackstone’s expertise would let me try things on for size, and hopefully arrive at a varied diet of work.

Pupillage at Blackstone involves sitting with four senior juniors who each specialise in a different area of law, usually one each in commercial law, public law, employment law, and a fourth area (e.g., regulatory, competition or sport).

Pupillage at Blackstone is non-practising, so pupils don’t undertake their own paid work. Instead, pupils are immersed in their supervisor’s practice and tend to do first drafts of whatever their supervisor is working on, be it a pleading, skeleton argument, or advice. Pupils at Blackstone also complete five pieces of set work which are assessed by members of chambers other than the supervisors, as well as seven advocacy assessments. It sounds like a lot of assessment, but the focus of pupillage at Blackstone is very much on learning and development. Although the pupillage year is challenging, in that it is an introduction to the profession as well as areas of law that pupils will not have studied before, ample feedback is given throughout. I felt that the process was transparent, and that we had the chance to improve before the tenancy decision was made.

The transition from pupil to tenant

The first year of practice is inevitably a leap from pupillage. Although the core skills are ones that you learned in pupillage, much will be unfamiliar, and you can only learn how to manage your own practice by doing it.

I found the clerks an invaluable resource in practical matters like estimating the time that a piece of work might take (almost always longer than you think) and managing diaries. On matters of procedure, substantive law, or strategy, I was continually struck by the generosity of fellow members of chambers of all levels of seniority with their time.

What is your practice is like now?

Like most junior members of chambers, my practice crosses different areas of law. I work with magic circle firms on large multi-jurisdictional commercial disputes, unled matters in the County Court or the Employment Tribunal, and have a substantial pro bono public law practice where I am both led and unled. The amount of time I spend in Court varies considerably across the course of the year. Right after I joined chambers I was brought onto a 6 week hearing for an account of profits in the Commercial Court, and am regularly in the High Court for judicial reviews and in the Employment Tribunal. However, when preparing for a big trial, I might have two months where my practice is entirely paper-based.

What is the culture of chambers?

I have found chambers to be markedly collegiate. Because most people at Blackstone stay there for the rest of their professional lives, there is a real commitment to getting to know people, and creating a friendly and supportive working environment. Doors are open, and we rely on each other to ensure that our clients are getting the best advice. The nearly 1:1 ratio of silks to juniors creates a dynamic intellectual and social environment.

Top tips for those wanting to become a barrister/secure a pupillage at your chambers

The Blackstone pupillage process is very focussed on academic ability and advocacy potential. Still, it is a broad church, and there is no single “type”. As well as people who have gone from quad to quad to quad, our ranks are made up of former social workers, bankers, musicians, trade unionists.
