A Client Asks: 'Weren't You My Lawyer?'
Norton Herrick raises stakes in his lawsuit against Skadden, Arps, Slate, Meagher & Flom, saying there are other cases in which the law firm turned against one client, or that client's best interests, so that another client could profit; Herrick's lawsuit, filed four year ago, holds that he was a client of Skadden Arps as a member of TOG Acquisition Co but that firm turned its back on him in dispute he is having with other TOG investors and sided with them just as potentially lucrative business deal was culminating; firm says that two of investors, Stephen D Weinroth and Stephen C Swid, as well as TOG, were its true clients, not Herrick, and that it had no choice other than to complete deal without him; client disputes, particularly those involving a firm's representation of two or more parties whose interests may be in conflict, have become more of a problem as legal business has become more competitive and firms have grown in size; photos (M)
