The National Association of Criminal Defense Lawyers filed its amicus brief [PDF] last week in support of Ian Norris, the imprisoned ex-CEO of the British-based Morgan Crucible Co. Norris is seeking review of his conviction last year for witness tampering in a case that is being closely watched in legal, business, and diplomatic circles here and abroad.

Norris, the first foreign national ever extradited on an application from the U.S. Justice Department’s antitrust division, was originally accused of price-fixing in the carbon-brush industry. But a jury found him guilty only of witness tampering and he was sentenced to 18 months in prison last December.
