Since joining in 1998 following pupillage in Chambers and an earlier career as a veterinary surgeon, Siân has established a thriving practice in professional liability claims, insurance and construction/engineering. Siân has a particular interest in disputes involving technical and scientific elements and this has led to a strong construction and engineering practice with regular appearances in the TCC.
Ranked by Legal 500 in the Leading Juniors – Professional Negligence section: ‘Very bright, robust, dedicated and thorough’'; "Siân Mirchandani provides sensible, commercial and practical advice"; '"Her strong understanding of the key issues in a case ensure that solicitors feel confident that 'every angle is covered; “Dedicated and articulate, with excellent attention to detail.”
Sian is also ranked as a leading junior in Professional Negligence by Chambers & Partners: “Regularly acts in complex professional negligence disputes. She demonstrates notable expertise in financial claims and cases with an international element”; "The great thing about her is that on every occasion her advice is strong, firm and consistent, which allows us to get an excellent settlement." "She's very strong on complex matters."
Impressed solicitors say that “rising star for construction and solicitors claims” Siân is “one to watch", and that Siân is “a joy to work with - very bright”.
Siân has wide and considerable experience of professional liability claims, including claims against lawyers (solicitors and barristers), architects, engineers, insurance brokers and agents, surveyors and valuers, accountants, financial services professionals, land management agents, farm management agents, estate agents, clinicians and veterinary surgeons. Siân is a TECBAR accredited adjudicator.
She also has experience of professional disciplinary matters, arbitrations, adjudications and mediations. Having qualified from Cambridge University as a veterinary surgeon in 1992, Siân worked in academic and general practice as a veterinary surgeon before coming to the Bar and joining Chambers in 1998. Siân has since advised the Royal College of Veterinary Surgeons, (RCVS) and represented veterinary surgeons before the RCVS disciplinary panel. Siân now provides lectures on professional conduct and professional negligence to veterinary students which are accredited by the RCVS.
Siân has been editor and co-author of the chapter on claims against health professionals in the 5th and 6th Editions of Jackson & Powell on Professional Negligence.
Siân is a member of the Professional Negligence Bar Association, COMBAR, TECBAR, the Chancery Bar Association and the London Common Law & Commercial Bar Association.
‘Very bright, robust, dedicated and thorough’ - Legal 500, 2015 (Leading Junior: Professional Negligence)
Siân has considerable experience of claims involving professionals of all types. The Directories speak of Siân as a “rising star for construction and solicitors claims”; “one to watch”, and her profile is described as continuing “to skyrocket”.
With a professional and scientific background, Siân relishes cases which involve scientific aspects or technical issues, and this has led to a strong practice in the Technology & Construction Court. Her practical, ‘hands on’ approach has led to instructions from civil engineering and other building contractors and sub-contractors, and this ‘pure construction’ work complements her continuing construction professionals’ practice.
Siân has particularly developed a practice involving claims arising from design and construction of farm or agricultural buildings, where the combination of her veterinary background and her experience in construction claims as well as professional liability claims has given her clients a considerable advantage.
In recent years Siân has been involved in defending high value claims against major firms of valuers in cases involving commercial properties packaged as ‘tax efficient’ investments in Denmark and the UK. These cases involved valuations using yields and estimates of rental income for hotels (K/S Lincoln et al v CBRE Richard Ellis) and factory outlet centres (Capita Alternative Fund Services & Matrix Securities v Drivers Jonas), where value was added due to the tax savings to be obtained.
Apart from the main fields of professional liability, Siân has also been involved with claims concerning agricultural land agents' negligence and estate agent’s negligence.
Siân particularly enjoys cases in all areas of her practice which involve working alongside solicitors, and other professionals, as part of an interchangeable team, dealing with vast amounts of documentation, or claims involving large numbers of sub-claims.
Siân has experience of using electronic databases and e-documents, rather than conventional paper documents, and has been involved in an e-disclosure exercise in a major construction claim arising from a housing estate.
Siân has acted in a variety of lawyers’ negligence claims, (acting for and against both solicitors and barristers). Siân acted on behalf of the Solicitors Indemnity Fund and the defendant solicitors in the "Immunity Appeals" in Arthur J.S. Hall v. Simons  1 AC 615). This case involved five appeals to the Court of Appeal and then the House of Lords, and centred on the question of whether an advocate should be liable in negligence for work carried out in court (or ‘at the door of the court’). The decision from a seven man House of Lords led to the abrogation of barristers' immunity from suit, which was a victory for the solicitors, who could then seek contribution from the barristers they had instructed. Another issue considered, which is of particular relevance in lost litigation claims against lawyers, was the question of when an attack on a previous court’s decision was an impermissible ‘collateral attack’.
Examples of her wide experience in this area include:
- Incorrect advice on planning permission requirements
- Claims arising out of mismanagement of adjudication proceedings.
- Loss of litigation / undersettlement
- Scope of solicitor's duty to client when more than one professional advisor.
- Collateral attacks on existing judgments
- Wasted costs applications
