  • In re: Polyurethane Foam Antitrust Litigation. Brought in as lead trial counsel for FXI 11 weeks before trial was set to begin. Plaintiffs collectively sought in excess of $3 billion in damages, claiming that market-leader FXI joined an 11-year conspiracy in the foam business immediately following the acquisition of the assets and employees of a former market participant. By putting together persuasive defenses to four separate trials in six months, S&C was able to secure favorable settlements. Decisions related to this representation are reported at 86 F. Supp. 3d 769 (N.D. Ohio, 2015), 2015 WL 520930 (N.D. Ohio, Western Division, Feb. 9, 2015), 2015 WL 1639269 (N.D. Ohio, Western Division, Feb. 26, 2015), 2015 WL 4459636 (N.D.

Plaintiff Energy Transfer had claimed in excess of $1 billion plus exemplary damages against Enbridge, claiming that Enbridge stole away Enterprise Products from Energy Transfer as part of an effort to create a competitively significant pipeline.

Enbridge Energy, C.A.  11314-VCS. On appeal, the Delaware Supreme Court affirmed in part and reversed in part, “chang[ing] course” from its earlier decision in Brinckerhoff III, “to the more traditional definition of bad faith utilized in Delaware entity law.” See Brinckerhoff v. Enbridge, 2017 WL 1046224 (Del. Supr.).
  • Brinckerhoff v. Enbridge Energy Company, Inc., C.A. No. 5526 (Del. Ch. Ct. 2011). Successfully represented the directors appointed by Enbridge, Inc. in a derivative lawsuit seeking to unwind the critical restructuring of the Alberta Clipper pipeline that occurred during the depths of the financial crisis. The Chancery Court dismissed that lawsuit with prejudice on a motion to dismiss. After two separate arguments before the Delaware Supreme Court, the Supreme Court affirmed the dismissal on the ground advanced by the Enbridge directors. The decision of the Delaware Supreme Court is reported at 67 A.3d 369 (Del. 2013).

Decisions in Coe are reported at 2014 WL 585858 (W.D. Wash. Feb. 14, 2014), 2014 WL 722501 (W.D. Wash. Feb. 24, 2014), 2014 WL 5162912 (W.D. Wash. Oct. 14, 2014) and 2014 WL 5450111 (W.D. Wash. Oct. 24, 2014).

  • In re Trident Microsystems.

  • Franco v. Holder. Represented a class of severely mentally disabled immigrants seeking assistance in connection with prolonged detentions in immigration proceedings. In April 2013, the United States District Court entered a permanent injunction providing for counsel for those detained individuals suffering from serious mental illnesses in California, Arizona and Washington State, which has been hailed as a significant extension of Gideon v. Wainwright. In September 2015, S&C secured a favorable settlement providing additional relief to a separate class of individuals who had previously been ordered removed in violation of the Rehabilitation Act.  Decisions of the United States District Court related to this assignment are reported at 767 F.
