Attorneys Jack Guernsey, Nancy Gellman, Robert Feltoon and Nicholas Centrella were retained by the preeminent New York law firm of Cravath, Swaine & Moore LLP to represent it in a lawsuit filed by a former client, Airgas, Inc. seeking, inter alia, to enjoin Cravath from representing Air Products, Inc., in connection with a possible acquisition of Airgas by Air Products. The lawsuit, originally brought by Airgas in the Philadelphia Court of Common Pleas, sought an emergency disqualification order precluding Cravath from representing Air Products in a first-filed lawsuit pending in Delaware Chancery Court and from advising Air Products in connection with a possible acquisition of Airgas. The attorneys from Conrad O’Brien successfully defeated the request for a special injunction at a hearing held before Judge Albert W. Sheppard, Jr. Following that hearing, Conrad O’Brien removed the case to the U.S. District Court for the Eastern District of Pennsylvania and filed a motion asking that court to stay the proceedings pending the outcome of the first-filed Delaware lawsuit.   On February 22, 2010 Judge Eduardo C. Robreno issued a memorandum opinion granting the motion for stay. 2010 WL 624955 (E.D. Pa. Feb. 22, 2010). Cravath thereafter successfully defeated Airgas’s attempt to disqualify it from representing Air Products in the Delaware Chancery Court before Chancellor William B. Chancellor, III, who ruled against disqualification on March 5, 2010.
