The concept of failure to prevent has grown from its roots in the U.S. Foreign Corrupt Practices Act and is making inroads into the responsibilities of tax advisers.  The recent trend begs the question, do advisors have a duty to prevent the evasion or improper reduction of tax or to report the activity in advance?  A team of international advisors looks at the evolution of obligations: Peter Utterström of Peter Utterström Advokat AB, Stockholm, looks at the origin of the concept.  Gary Ashford of Harbottle & Lewis, London, looks at recently adopted legislation in the U.K. imposing strict liability on advisers to naughty clients.  Lawrence Feld, Attorney at Law, New York, looks at its presence in the U.S. Swiss Bank Program of the Justice Department.  Dick Barmentlo of Jaegers & Soons, Amsterdam, addresses a recent case in the Netherlands that imposes civil liability on a Netherlands trust company and its employees for lost taxes suffered by the Dutch tax administration.
