US lawyers are facing the threat of tough new sanctions from American market regulators under proposed legislation that would hand the Securities and Exchange Commission (SEC) the right to fine individual attorneys up to $2m.

The measures are contained in the Care Bill 2003, which was approved in April by a majority of 95-to-five in the US Senate. Amendments added by senators Carl Levin and Bill Nelson would allow the SEC to fine lawyers believed to have violated securities law.
