A New York state judge on Friday threw out a $500 million lawsuit by an Austrian bank against Chadbourne & Parke stemming from advice its Moscow office gave the bank about the structure of an investment vehicle whose legality later came under scrutiny.

Creditanstalt Investment Bank AG, which later merged with UniCredit Bank Austria AG, claimed the investment vehicle fueled an investigation by Russian authorities beginning in 1999 that ultimately resulted in the seizure of bank accounts and the bank pulling out of Russia.
