The Legal Cheek View
Leading public law set Cornerstone Barristers has premises in London, Birmingham, and Cardiff. With 67 barristers, including 15 KCs, it is one of the larger sets. While initially focused on local authority work, members of Cornerstone now take on work across a broad range of public law areas, including administrative law, housing, licensing, planning, environment, property, community care, inquests and inquiries, and the new and exciting field of climate litigation. One junior observes that “the quality of work has noticeably stepped up in the last few years as we become more established as a public law set rather than a “housing” or “planning” specialist set”, though another notes that “public authority work is [still] what we are best known for”. Cornerstone’s clients include private developers, companies, public development agencies, and central and local governments.
One example of the set’s growing strength and expansion comes from a glance at the roster of recent joiners. Over the last year alone this has included barristers who specialise in environmental, Court of Protection, property, and public law.
A lot of Cornerstone’s work has a real-world impact. As one tenant says: “A planning case might lead to long term, tangible change to a town, a housing case might have life-changing consequences for the individual — there is often a lot at stake when we receive instructions which makes for stimulating work.” Another junior puts it like this: “We work on some of the most pressing public issues of the day: discrimination and equality, access to housing, developments and planning, immigration and eligibility for public services. It’s all about the way public services are actually delivered in practice, and what’s best is that we act on both sides.” Or, the short version from one happy member, “I love my job!”
Recent high-profile member appearances include the Post Office IT scandal and subsequent public inquiry; an examination into the largest solar farm in the UK; an enquiry into the DWP’s Artificial Intelligence usage; Uber’s London licensing appeal; a legal challenge against the UK’s government’s environmental travel guidance; and judicial review claims relating to the Home Secretary’s use of former military bases for asylum housing. Other notable cases have included the Grenfell Inquiry and the UK’s first “buffer zone” outside an abortion clinic. The establishment of Cornerstone Climate, a hub for climate litigation and advice, has also brought in instructions on two of the most significant climate change cases of the last year — the Finch Litigation in the Supreme Court and the Carbon Budget Delivery Plan challenge. Such varied and challenging work means that “there is rarely a boring day in the office”.
An insider describes the career progression at Cornerstone as tending to start with “quick summary possession hearings in the County Court” but then progressing to “pick up opportunities to broaden and deepen your practice”. The set also provides “good opportunities to undertake led work”.
The supportive nature of the set leads proud tenants to claim that “Cornerstone is rightly recognised as one of the most collegiate and supportive sets of chambers at the bar”. Many members describe the set as being “truly like a family” and all praise the open-door policy, which insiders say “is something we pride ourselves on in chambers”. Another member tells us that having a supportive atmosphere is a specific strategic objective of the set: “Being able to pick the brains of an experienced practitioner on a key point not only makes your work better, but it also makes doing the job significantly less stressful, which is very welcome, especially when approaching new areas.” The female members of Cornerstone also have their own designated WhatsApp group where they celebrate each other’s successes and offer advice.
Chambers also has “strong policies supporting those with families or other caring responsibilities, and a committee with wellbeing at its heart.” One junior tells us that they “developed an autoimmune condition which meant [they] needed to go slow for a while”, but “both the staff and other members of chambers have been reassuring, understanding, sympathetic, everything you can expect… and the best of all, not surprised or patronising as [they] have rebuilt [their] practice and strength”. As one happy tenant sums up, Cornerstone is home to the “best bunch of people you could ever work with”.
The high praise continues when it comes to work life balance with one well-travelled tenant simply saying “having been in three different sets, I have found Cornerstone to be the best at this.” Another source offered this insight: “Chambers recognises that barristers can only build a sustainable, satisfying practice in the long term if they are well-supported to have a life beyond work. I have not once experienced pushback for taking long holidays, nor building a practice where working on the weekend is the exception rather than the norm.” The clerking team is also said to be “marvellous” at improving WLB and “sensitive to members’ needs”. But aspiring barristers should not forget that “this job is not for the faint hearted or the work-shy” and that “there are of course times when litigation tilts the balance more towards work”.
When it comes to the social side of chambers, one member exclaims: “Where do I start? Our numerous chambers’ charity cycling trips across the UK and France? The holidays I’ve taken abroad with friends from chambers? The weddings and housewarming parties and personal events we’ve attended together? Our chambers book club? Our Friday cocktails at Catalyst on Gray’s Inn Road? The Christmas dance parties?” The set really lives by the work hard, play hard mantra and, for those who are less active socially, there is still “always a colleague to have lunch or coffee with” and a “lively chat on WhatsApp”.
Cornerstone takes its wider commitments seriously with more than half of its members committing an average of 50 hours pro bono each year, possessing an active corporate social responsibility committee, and being a member in the Bar Council’s newly established Sustainability Network.
In terms of the buildings, the traditional Inns of Court building which houses the set, backs onto Gray’s Inn Gardens and had a substantial facelift in 2016, meaning it now “boasts a modern, client-facing, air-conditioned conference suite”. Still, insiders label the space “warm and welcoming rather than glitzy and impressive”. Inside, you can decorate to your individual tastes with one offering this glimpse into their abode: “My room in chambers is absolutely beautiful and looks out onto Gray’s Inn walks – I sit next to a great big window. I have filled it with plants, prints and rugs to match my cosy vibe, but everyone is different. The outside of chambers is in keeping with the look of Gray’s Inn.” A large room is specifically set aside for the newest tenants to share, which one member says “was an important feature of my first years in chambers and a setting where several friendships were cemented”.
Technology-wise, “members are well connected to chambers’ IT infrastructure, both in chambers and remotely, and are supported by well-informed and helpful IT staff”. One praises the “IT team” for being “endlessly patient” and “always on hand to sort things when crisis strikes”. Other facilities on offer are hot desking, a well-supplied library, and showers for those members who cycle to work.
Cornerstone offers two pupillages each year, with a generous award of £70,000. Training at the set is highly-rated. One junior gleans “My pupil supervisors have remained mentors as well as colleagues to me, and I feel well supported as a junior tenant. I have noticed throughout my own journey into self-employed practice the extent to which the skills carefully honed during pupillage have benefitted me.” The learning continues into tenancy, with one member commenting that, whether leading or being led, they “have the opportunity to learn from and with [their] colleagues in chambers and find the benefits of collaborative working invaluable”. The set facilitates continued training by laying on “a plentiful and varied programme of seminars, webinars and conferences”.
Pupils at Cornerstone sit with at least three pupil supervisors during the first nine months of pupillage, who “go above and beyond in making sure that you develop with each and every piece of work” and together cover the set’s core practice areas. One pupil reports: “Throughout my pupillage, I have received thoughtful and carefully considered feedback… supervisors are keenly invested in pupils’ development and enthusiastically celebrate pupils’ progress and achievements.” During the first six, pupils can expect to accompany their supervisors, who are “at the peak of their careers”, on trips to Planning Inquiries, the High Court, the Court of Appeal and even the Supreme Court, as well as lower courts and tribunals. In their second six, pupils will be on their feet and representing in court themselves. Decisions as to tenancy are made on the basis of the qualities of individual applicants, as well as whether there is a vacancy for a junior tenant.
Cornerstone recruits through the Pupillage Gateway. After application sifting, 20 candidates are invited to a first-round interview, which is general in nature and lasts around 15 minutes. 10 candidates will then be invited to a more extensive second-round interview, which lasts around 30 minutes and typically involves an advocacy exercise and a case analysis exercise.
Cornerstone Barristers emphasises on its website that it welcomes pupillage applications from everyone and “would particularly encourage candidates to apply from backgrounds that have not traditionally been represented at the Bar”. Indeed, a few years back, alongside Field Court Chambers, Francis Taylor Building, Kings Chambers, and Landmark Chambers — all other specialist Planning, Property and Public Law sets — Cornerstone Barristers launched a mentoring scheme for underrepresented groups at the bar. The scheme is intended to encourage individuals from groups that are not well represented at the bar to consider becoming barristers. Cornerstone also recently joined the 10,000 Black Interns programme “in order to play [their] part in making the Bar a profession of equal representation and opportunity”.
