IN A DECISION that at least one lawyer said could affect the $512 million dollar class action settlement in the Christie’s and Sotheby’s price fixing case, the U.S. Court of Appeals for the Second Circuit yesterday reinstated claims by customers involved in auctions overseas.

The Second Circuit vacated the decision of Southern District Judge Lewis A. Kaplan, who had dismissed the so-called foreign claims for a lack of subject matter jurisdiction just weeks before he conditionally approved the $512 million settlement on the domestic claims in 2001.
