Helping you succeed in tomorrow's world
I am so proud to lead an amazing diverse, dedicated team of regulatory lawyers who are respected by all the clients they work with. We help clients shape and respond to regulatory changes being driven by the transformational changes of digitalisation, decarbonisation and urban dynamics.
The regulated procurement lawyers I work with are particularly recognised for their ability to use their advisory experience to deliver the best outcomes in litigation. Our forensic approach to dissecting tender documents and procurement processes is required in order to advise on the merits of a procurement challenges. We use this knowledge to approach major procurements for our clients (whether contracting authorities or suppliers) to challenge and test evaluation criteria and methodologies. This broad contentious experience means we advise with a depth of knowledge on risk of challenge to a procurement process, so clients know where to focus their time and resources appropriately. We also represent clients in repelling initial challenges to a procurement process and defending challenges which proceed to litigation.
