When last I wrote about ascertainability, I noted that a debate over the propriety of “ascertainability-by-affidavit” continued to percolate within the First Circuit even as lower courts relied on In re Nexium Antitrust Litigation to certify classes containing uninjured class members. Specifically, I noted a couple of developments. First, in In re Asacol Antitrust Litigation, Judge Casper of the District of Massachusetts had rejected defendants’ ascertainability arguments and certified a class containing uninjured individuals, relying on In re Nexium for the proposition that uninjured individuals could be identified and excluded after certification via submission of affidavits.

As this overview shows, the majority of courts have held that under Bristol-Myers, they do not have personal jurisdiction over the non-resident defendants with regard to claims brought by the non-resident plaintiffs.
