DLA Piper's team has a wealth of experience of domestic and cross-border mandates, with the work spanning matters such as rights issues, placings, block trades, dual listings, step-ups and public takeovers. It captures a particularly significant share of the market for AIM IPOs; a recent highlight involved practice head Alex Tamlyn and senior associate Robert Newman acting for Rosenblatt in its £43m AIM listing (representing the largest UK law firm IPO to date). Also in the legal services arena, John Campion, Jonathan Watkins and Newman are advising UK law firm Knights plc on its planned AIM IPO. Tamlyn also recently worked with senior associates Johannes Poon and Karin Kirschner to advise Zeus Capital (as NOMAD and broker) on the AIM listing of, and associated placing of shares by, OnTheMarket Plc. Martin Penn acted for PureTech Health Plc in its £72m placing. On the regulatory front, the firm has a  strong relationship with the London Stock Exchange, enabling its team to gain an understanding of current and upcoming rules and regulations. Tamlyn is Chair of the Primary Markets Group on the London Stock Exchange. Elsewhere, the firm has a particularly strong US securities law capability, with US-qualified partners Tony Lopez and George Barboutis having expertise in this area. Charles Severs and DLA Piper are other notable practitioners in the team.

  • Sentencing guidelines for corporate manslaughter

    In February 2010 the Sentencing Guidelines Council (the SGC) issued definitive guidelines to courts on imposing appropriate sentences for corporate manslaughter and health and safety offences causing death. The SGC states that fines imposed on companies found guilty of corporate manslaughter should not fall below £500,000, while fines in respect of health and safety offences that are a significant cause of death should be at least £100,000. Crucially, the SGC declined to provide for a fixed link between the imposed fine and the turnover or profitability of the offending company.‚Ä©
