Discovery battles are getting ugly in Boyer v. Sears Roebuck & Co., the proposed class-action suit that accuses Sears of myriad illegal debt-collection practices, including harassment of credit-card holders who have fallen into bankruptcy.

In a brief filed in U.S. District Court last week, attorneys Laurence S. Berman and Craig D. Ginsburg of Levin Fishbein Sedran & Berman argue that Sears has “objected to virtually every aspect” of their discovery requests with “boilerplate” objections. So, they say, Sears has provided “almost no information” in response to their interrogatories and not a single requested document.
