Mark Hewland - Simmons & Simmons

Within: Employment: employers

Simmons & Simmons’ employment practice is highly regarded for its work on complex and reputationally sensitive matters, including #MeToo investigations, whistleblowing issues and senior misconduct, and recently led on a high-profile investigation for Baker McKenzie into the firm's handling of sexual assault allegations against a senior partner. The practice also stands out for its expertise in big-ticket litigation, particularly for financial services sector clients, and in multijurisdictional work which requires a deep understanding of domestic, European and international regulations. Several professionals in the team have significant in-house experience. Another recent highlight saw the firm act in the Supreme Court for headhunter Mary Caroline Tillman on a closely watched restrictive covenant dispute. Julian Taylor heads the practice, while Mark Hewland is another name to note.

  • Failure to counter financial crime: Norwich Union Life

    In December 2007, the Financial Services Authority (FSA) imposed a fine of £1.26m on Norwich Union Life (part of the Aviva Group), one of the largest life insurance businesses in the UK with around seven million customers. The fine related to failures to take reasonable care to establish and maintain effective systems and controls for countering the risks of financial crime. The fine is the latest confirmation of the emphasis being placed on protecting clients and customers from the threat of financial crime.
