Illinois throws spanner in works for Mayer Brown

UK firm Rowe & Maw and US firm Mayer Brown & Platt will not be able to merge fully until the State of Illinois gives the go-ahead for limited liability partnerships (LLPs)

The news comes in the wake of the firms’ deal to create a £435m (A$1.18bn) law firm – the tenth-largest in the world. In the meantime, the UK partnership will be widened to become a multinational partnership and will subsume Mayer Brown‘s London office. The Mayer Brown US partnership, headquartered in Chicago, will remain technically separate from the London office, although the two firms officially merged on 1 February.
