Masenthin; Dorinda Snyder; Riboerto Arvizu, individually and on behalf of a class of others similarly situated, Plaintiffs-Appellees, TYSON FOODS, INC.; Tyson Fresh Meats, Inc., Defendants-Appellants. No. 07-3162. United States Court of Appeals, Tenth Circuit. July 28, 2008. Submitted on the briefs:[*] Joel M. Cohn, Michael J. Mueller, Evangeline C. Paschal, Christopher M. Egleson, Akin Gump Strauss Hauer & *1326 Feld LLP, Washington, DC, for Defendants-Appellants. George A. Hanson, Eric L. Dirks, Stueve Siegel Hanson, LLP, Kansas City, Missouri, for Plaintiffs-Appellees. Before MURPHY, McKAY, and ANDERSON, JJ. MURPHY, Circuit Judge. Defendants-appellants Tyson Foods, Inc. and Tyson Fresh Meats, Inc. (collectively, "Tyson") appeal from the district court's interlocutory order denying their motion for partial summary judgment. We ordered the parties to submit briefs addressing whether this appeal should be dismissed on the ground that the order appealed from was not final. Tyson argues that we have jurisdiction over the appeal under 28 U.S.C. § 1292(a)(1) because the interlocutory order had the practical effect of modifying an injunction that had been entered against its predecessor-in-interest in another case, to which Tyson was now subject. Tyson's argument is that (1) the injunction in question requires it to comply with a certain provision of the Fair Labor Standards Act of 1938 ("FLSA"), (2) the interlocutory order denying summary judgment changed how that provision of FLSA is interpreted in the district, and (3) the interlocutory order therefore had the practical effect of modifying the injunction. We disagree. Because we hold the interlocutory order had no precedential effect and could not have modified the injunction, we dismiss the appeal. I. Consideration of our jurisdiction over this appeal therefore requires analysis of the interplay between the previous lawsuit in which the injunction was entered and the present lawsuit. The previous lawsuit was brought more than fifteen years ago against IBP, Inc., a company that slaughtered cattle and swine and processed and packaged the beef and pork. It was brought by Robert Reich, the Secretary of the Department of Labor ("Reich Case") under the FLSA. The second lawsuit is the class-action case presently before us in which the numerous plaintiffs, on behalf of themselves and the class, have accused Tyson, also in the business of slaughtering cattle and swine and processing and packaging beef and pork, of, among other things, violating the FLSA. In the first phase of the Reich Case, see Reich v. IBP, Inc. (Reich I), 820 F.Supp. 1315 (D.Kan. 1993), the district court held that the time spent by the IBP employees donning and doffing of standard protective gear (hard hats, ear plugs, safety footwear and eyewear) ("Standard Gear"), and donning and doffing sanitary outergarments, was not time for which those employees had to be paid under FLSA. The district court, however, also held that the time spent by the IBP knife-wielding employees donning and doffing specialized protective clothing and gear was compensable. Following certification by the trial court under 28 U.S.C. § 1292(b), this court upheld the district court's ruling that the donning and doffing of the outergarments and Standard Gear was not compensable. See Reich v. IBP, Inc. ("Reich II"), 38 F.3d 1123, 1125 (10th Cir.1994). We held that donning and doffing Standard Gear was not "work" under the FLSA. Id. at 1125-26. We held that the time spent donning and doffing the protective outergarments also was not compensable because it was "essentially time used to change clothes" and because the wearing of such outergarments was primarily for the employees' benefit and, therefore, not "integral and indispensable" to IBP's operations. Id. at 1126. In 1996, in the second phase of the Reich Case, the district court entered an *1327 injunction (Reich Injunction) ordering IBP to not employ any employee "for workweeks longer than 40 hours without compensating such employee for his or her employment in excess of 40 hours per workweek at a rate not less than one and one-half times the regular rate at which he or she is employed." Aplt.App., Vol. II at 470; Reich v. IBP, Inc., No 88-2171-EEO, 1996 WL 445072 (D.Kan. July 30, 1996). After the Reich Case, IBP and Tyson merged and Tyson succeeded to IBP's assets and liabilities. As noted above, Tyson's argument to this court is that the district court's order denying its motion for partial summary judgment had the practical effect of modifying the above portion of the Reich Injunction. Therefore, despite the fact that appeals from denials of summary judgment are generally dismissed on jurisdictional grounds as appeals from interlocutory orders, Tyson argues that here it is appealing an interlocutory order modifying an injunction, over which we have jurisdiction under 28 U.S.C. § 1292(a)(1). Tyson argued in its motion for summary judgment that judgment should be entered in its favor as to any plaintiff's claim for compensation for time spent donning and doffing sanitary outergarments and Standard Gear, because Reich II shut the door on claims that those activities were compensable. The district court denied summary judgment on the ground that the Supreme Court's decision in IBP, Inc. v. Alvarez, 546 U.S. 21, 126 S.Ct. 514, 163 L.Ed.2d 288 (2005), cast doubt on the analysis behind our holding in Reich II. The district court held that summary judgment was inappropriate because it was "convinced that the Circuit, if given the opportunity to revisit the issues in Reich [II], would approach its analysis of the pertinent issues differently in light of Alvarez regardless of whether the Circuit ultimately reached the same conclusions concerning compensability." Garcia v. Tyson Foods, Inc., 474 F.Supp.2d 1240, 1246 (2007). The district court held that it believed this court "might reach a different conclusion on compensability if analyzed in the context of Alvarez," but that even if we did not, further analysis would be required. Id. (emphasis added). The district court, therefore, did not rule that the time spent donning and doffing sanitary outergarments and Standard Gear was compensable after Alvarez, but simply that Reich II no longer definitively decided the question. Tyson argues on appeal that the district court's order denying summary judgment "fundamentally changed the FLSA requirements that are incorporated by reference in the injunction." Aplt. Br. in Support of Jurisdiction at 8. In other words, it argues: (1) that the Reich Injunction ordered IBP, and now Tyson, to pay its employees — now and into the future — for overtime at a rate not less than one and one-half times the regular rate, (2) how much time and overtime an employee works can only be determined by reference to what work is compensable under present FLSA law, and (3) the district court's order denying summary judgment "changed the [present FLSA] law and thus the injunction itself." Id. at 11. It argues: Prior to the district court's order, Reich [II] foreclosed any possibility that Tyson could be charged with contempt for failing to compensate employees at non-union facilities for donning and doffing of standard gear and sanitary overgarments that Reich [II] found to be noncompensable. The district court's decision here, however, opens the possibility that the DOL could seek contempt charges against Tyson for the *1328 very acts that were deemed noncompensable in Reich [II]. Id. at 12. As will be explained in detail below, we disagree that the district court order at issue here had any practical effect on the Reich Injunction. While it is certainly arguable that the Supreme Court's decision in Alvarez had a practical effect on the Reich Injunction, that is not our concern at this point in time. II. "As a general rule, only final decisions of the district court are appealable." Pimentel & Sons Guitar Makers, Inc. v. Pimentel, 477 F.3d 1151, 1153 (10th Cir. 2007) (citing 28 U.S.C. § 1291). Nevertheless, as noted above, under 28 U.S.C. § 1292(a)(1), the courts of appeal for the various circuits have jurisdiction over "[i]nterlocutory orders of the district courts of the United States, ... or of the judges thereof, granting, continuing, modifying, refusing or dissolving injunctions." Here, Tyson claims that the district court's order denying summary judgment in this case modified the Reich Injunction. The parties agree that the order denying summary judgment did not expressly modify the Reich Injunction; it was, after all, entered in a separate legal proceeding. But Tyson argues that the order had the practical effect of modifying the injunction. As discussed above, Tyson's argument has two premises: (1) that the Reich Injunction ordered it to comply with a certain provision of the FLSA (i.e., properly compensating employees for overtime), and (2) that the district court's order denying summary judgment changed what activities are compensable under the FLSA in the district, thus changing how much time its employees are considered to be working and having the practical effect of modifying the Reich Injunction. A. As to Tyson's first premise, we note that following the district court's order denying partial summary judgment, Tyson filed a motion under Federal Rule of Civil Procedure 59(e) asking the district court to alter or amend its denial. In its motion, Tyson asked the court to reverse its decision or, if it decided not to do so, to "acknowledge it ha[d] modified the [Reich] injunction, either explicitly or as a practical matter, by ruling that the standard items and `sanitary outergarments' are no longer non-compensable as a matter of law." Aplt. App., Vol. II at 340. In its reply to plaintiffs-appellees' response to the motion, Tyson clarified its claim. It argued that "[b]y eliminating a long-standing defense that certain clothing items ... are non-compensable as a matter of law, the Court has effectively modified the Reich injunction's admonition that IBP was to take action consistent with the `activities found [by Judge O'Connor and the Tenth Circuit] to be compensable under the Act.'" Id. at 382-83 (quoting Reich, No. 88-2171-EEO, 1996 WL 445072) (second alteration in original). Tyson argued that the district court's order denying summary judgment "wholesale eliminated defenses that both the [Department of Labor] and IBP clearly understood were available in light of the Tenth Circuit's liability decision in Reich [II]." Id. at 383 n. 2. In denying Tyson's motion, the district court held "[t]he court ... did not modify the Reich injunction and its [order denying summary judgment] did not have the practical effect of modifying the injunction." Garcia v. Tyson Foods, Inc., No. 06-2198-JWL, 2007 WL 1299199 at *2 (D.Kan. May 2, 2007). But the district court never reached Tyson's second premise, i.e., that the court's order changed the law regarding what activities are compensable under the FLSA in the district. Instead, the *1329 court determined that the Reich Injunction only compelled compliance with the FLSA in regard to the activities that the Reich court found to be compensable. The court held that [n]one of the provisions of the injunction addresses the donning and doffing of standard clothing or any other activity that the Reich court concluded was non-compensable. In fact, the injunction speaks only to those activities found by the Reich court to be compensable and the injunction directs defendants to take certain actions with respect to only those activities. Id. Nevertheless, the district court's determination that the Reich Injunction would not compel compensation for the activities found non-compensable in Reich I and Reich II is not binding on this court. Therefore, we will accept, purely for the sake of argument, Tyson's contention that the Reich Injunction is properly interpreted as a general order to properly pay overtime under the FLSA, however that statute might be later interpreted. B. As to Tyson's second premise, i.e., that the order denying summary judgment had the practical effect of modifying the Reich Injunction, we have held that "courts of appeals insist on looking beyond the captions and vocabulary attached to district court orders to determine the actual, practical effect of an order before exercising appellate jurisdiction under § 1292(a)(1)." Pimentel, 477 F.3d at 1153. Thus, "[w]hether an order ... modifies an injunction is determined by its actual, practical effect." Id. at 1154. When a district court's order does not expressly or technically modify an injunction, but has the practical effect of modifying an injunction, this court has jurisdiction where an appellant will suffer "a serious, perhaps irreparable, consequence" that "can be effectively challenged only by immediate appeal." Hutchinson v. Pfeil, 105 F.3d 566, 569 (10th Cir.1997) (quotation omitted). Citing to these propositions, Tyson argues that the district court's order "fundamentally changed" the state of FLSA law. Aplt. Br. in Support of Jurisdiction at 8. But Tyson does not explain how a district court order denying summary judgment could accomplish this feat. First, we note that the argument presented by plaintiffs-appellees to the district court in the present case was based on the Supreme Court's decision in Alvarez. Thus, since the time Alvarez was handed down, the Reich Injunction has likewise been susceptible to the argument put forth in this case, i.e., that Alvarez undermined this court's analysis in Reich II. Consequently, in arguing that the order denying summary judgment changed the law from its previous state, Tyson must be contending that this order would in some way bind the Kansas district court in later contempt proceedings regarding the Reich Injunction. We do not see any reason the district court would be so bound, and Tyson has not provided any. First, "it is clear that there is no such thing as `the law of the district.'" Threadgill v. Armstrong World Indus., Inc., 928 F.2d 1366, 1371 (3d Cir.1991). "[D]istrict court decisions cannot be treated as authoritative on issues of law. The reasoning of district judges is of course entitled to respect, but the decision of a district judge cannot be a controlling precedent." Bank of Am., N.A. v. Moglia, 330 F.3d 942, 949 (7th Cir.2003) (quotation omitted). Nor would claim or issue preclusion apply in this case as both require the issuance of a final judgment. See MACTEC, Inc. v. Gorelick, 427 F.3d 821, 831 (10th Cir.2005) ("Under Tenth Circuit law, claim *1330 preclusion applies when [certain] elements exist [including] a final judgment on the merits in an earlier action."); Arizona v. California, 530 U.S. 392, 414, 120 S.Ct. 2304, 147 L.Ed.2d 374 (2000) ("[I]ssue preclusion attaches only `[w]hen an issue of fact or law is actually litigated and determined by a valid and final judgment, and the determination is essential to the judgment.'") (quoting Restatement (Second) of Judgments § 27, p. 250 (1982) (second alteration in original)). Although the district court's order denying summary judgment might have sent a signal that a plausible argument could be made that Alvarez undermined Reich II to some extent, this is not a modification of the Reich Injunction. It is merely notice that one district court judge, in an interlocutory order, found not that time spent donning and doffing the Standard Gear and protective overgarments was compensable after Alvarez, but simply that it might be and that this court's analysis would have to be different. This is not sufficient grounds for jurisdiction under § 1292(a)(1). Section 1292(a) was intended to carve out only a limited exception to the final-judgment rule of 28 U.S.C. § 1291 and the long-established policy against piecemeal appeals. Consequently, the Supreme Court has cautioned that the statute should be narrowly construed to ensure that appeal as of right under § 1292(a)(1) will be available only in limited circumstances. Pimentel, 477 F.3d at 1153 (citations, quotations, and brackets omitted). A possible modification in the legal community's speculative expectation regarding how a certain district court might read Alvarez' effect on Reich II is not reason enough for this court to exercise jurisdiction. In the end, if the interpretation of FLSA has changed since the Reich Injunction was entered, and if that change therefore had the practical effect of modifying the Reich Injunction, that change was wrought by Alvarez and not by the district court's order at issue here. III. The appeal is DISMISSED. NOTES [*] After examining the briefs and appellate record, this panel has determined unanimously that oral argument would not materially assist the determination of this appeal. See Fed. R.App. P. 34(a)(2); 10th Cir. R. 34.1(G). The case is therefore ordered submitted without oral argument.
