1 EXHIBIT (5)(B) [CMS LETTERHEAD] June 27, 1995 CMS Energy Corporation Fairlane Plaza South Suite 1100 330 Town Center Drive Dearborn, Michigan 48126 Ladies and Gentlemen: I am Assistant General Counsel of CMS Energy Corporation, a Michigan corporation ("CMS Energy"). I refer to the proposed public offering by CMS Energy of its Class G Common Stock, no par value ("Class G Common Stock"), pursuant to CMS Energy's Registration Statement (Nos. 33-57719 and 33-57719-01) on Form S-3, as amended (the "Registration Statement"), filed pursuant to the Securities Act of 1933, as amended. Upon the issuance of the Class G Common Stock, CMS Energy will have outstanding two classes of common stock, the Class G Common Stock and its Common Stock, par value $.01 per share (the "CMS Energy Common Stock"). You have asked for my opinion on the effect, if any, on the fiduciary duties of the Board of Directors of CMS Energy (the "Board") under applicable Michigan law under these circumstances, particularly in a situation in which a decision or action of the Board or a committee of the Board might have a disparate effect on the holders of outstanding shares of any class of its common stock. Michigan case law affirms the general rule that directors of a Michigan corporation like CMS Energy have a fiduciary obligation to all of the shareholders of that corporation. L.A. Young Spring & Wire Corp. v. Falls, 307 Mich. 69, 101, 11 N.W. 2d 329, 341 (1943) ("The rule is thoroughly embedded in the general jurisprudence of both America and England that the status of directors is such that they occupy a fiduciary relation toward the corporation and its stockholders...[and are] entrusted with management of the corporation, for the benefit of the stockholders collectively..."); Wagner Elec. Corp. v. Hydraulic Brake Co., 269 Mich. 560, 564, 257 N.W. 884, 886 (1934) (Under Michigan law, "the directors of a private corporation stand in a fiduciary relation to its stockholders..."); Salvador v. Connor, 87 Mich. App. 664, 675, 276 N.W. 2d 458, 463 (1978) ("[I]n Michigan, directors and officers of corporations are fiduciaries who owe a strict duty of good faith to the corporation which they serve."). See also, Berman v. Gerber Prod. Co., 454 F. Supp. 1310, 1319 (W.D. Mich. 1978) ("Under the applicable Michigan law, it is clearly recognized that directors...are fiduciaries, and their dealings with the corporation and its stockholders are rigorously scrutinized." (citing Thomas v. Satfield Co., 363 Mich. 111, 108 N.W. 2d 907 (1961)). I have not located a Michigan case which specifically deals with a directors' fiduciary duty in the context of a dispute between the holders of separate classes of stock of a single corporation. However, Thompson v. Walker, 253 Mich. 126, 135, 234 N.W. 144, 147 (1931) confirms that directors have a fiduciary obligation to manage the corporation "for the common benefit of all the stockholders" (emphasis added) where there was a dispute between the majority and the minority shareholders of such corporation. See also, Wagner Elec. Corp., 269 Mich. at 566, 257 N.W. at 887 (majority shareholder "must act in the interest of all its shareholders" (emphasis added)); Salvador, 87 Mich. App. at 675, 276 N. W. at 463 (holding that a company "must be so managed so as to produce to each shareholder, the best possible return upon his investment" in a claim 2 brought by minority shareholder against majority shareholders (quoting 6 Callaghan's Mich. Civ. Jur. sec.166 (2d ed.)). Persuasive case law from other jurisdictions confirms that directors' fiduciary obligations extend to all shareholders of the corporation and not separately to one class of stock of the corporation or to one set of identifiable holders of a single class, and that the same legal duties are owed to the holders of each class of stock outstanding. Schanker v. E.I. du Pont, 329 F.2d 77 (2nd Cir. 1964); Robinson v. T.I.M.E. - D.C., Inc., 566 F. Supp. 1077 (N.D. Tex. 1983); I.P. Phillips v. Instituform of N. Am., Inc., 13 Del. J. Corp. L. 774 (1988). In addition, the Michigan Business Corporation Act, Mich. Comp. Laws sec.450.1541a(1) (1990) provides as follows: A director or officer shall discharge his or her duties as a director or officer including his or her duties as a member of a committee in the following manner: (a) In good faith. (b) With the care an ordinarily prudent person in a like position would exercise under similar circumstances. (c) In a manner he or she reasonably believes to be in the best interests of the corporation. Actions taken by the Board "within the limits of the law, matters of business judgment and discretion are not subject to judicial review" and may not be successfully attacked by the holders of any class of stock on the grounds that such actions violated the director's fiduciary obligations. Wagner Elec. Corp., 269 Mich. at 565-66, 257 N.W. at 887; Reed v. Burton, 344 Mich. 126, 73 N.W. 2d 333 (1955); In Re Butterfield Estate, 418 Mich. 241, 255, 341 N.W. 2d 453, 459 (1983). Based on the foregoing, and while I have found no Michigan case authority directly on point, it is my opinion that: (i) a Michigan court would hold that the Board owes an equal duty to all shareholders regardless of class and does not have separate or additional fiduciary duties to the holders of separate classes of stock; and (ii) a good faith determination by a disinterested and adequately informed Board, or committee thereof, which the Board honestly believes is in the best interests of CMS Energy, would be a defense to any challenge by or on behalf of the holders of either the Class G Common Stock or the CMS Energy Common Stock to a determination by the Board which could have a disparate effect on either class of CMS Energy common stock. This opinion is limited to the laws of the State of Michigan. I hereby consent to the filing of this opinion as an Exhibit to the Registration Statement and to all quotations or summarizations included in or made a part of the Registration Statement.
