Bill’s client and the client’s former colleague were sentenced last week in the United States District Court for the District of New Jersey. The client and his colleague were accused of orchestrating $3.9 million in bribe payments to foreign officials in various countries in order to secure government contracts for their company. The client pled guilty to one count of conspiracy to violate the Foreign Corrupt Practices Act, and one substantive count of violating the Foreign Corrupt Practices Act. The client was sentenced to two years of probation and received a $10,000 fine. As a result, he will go home to the Philippines. The Sentencing Guidelines called for a sentence of 57 to 60 months.
