Opinions

SEYMOUR, Circuit Judge.

James E. Clark brought this suit under 42 U.S.C. § 1983 (1982) against the Adult Parole Division of the Utah State Corrections Department, parole officer Robert Poulton, the Salt Lake County jail, and David Jorgenson, a transportation officer employed at the jail. Clark alleged that his constitutional rights were violated by two separate incidents of excessive force, and by the denial of medical treatment and of reasonable access to the mails during his pretrial detention in the jail. The district court referred the case to a magistrate pursuant to 28 U.S.C. § 636(b)(1)(B) (1988). The magistrate held an evidentiary hearing and submitted a report recommending that Clark’s claims be dismissed. The district court adopted this report and entered judgment accordingly. Clark appeals, asserting that the magistrate had no jurisdiction because the referral was not authorized by statute, that in any event the district court failed to conduct a proper de novo review of the portion of the report to which Clark had objected, and that the magistrate erred in his application of the law. We conclude that the magistrate was without jurisdiction, and we therefore reverse.

I.

BACKGROUND

The relevant facts are briefly as follows. While on parole following state court convictions, Clark returned to Salt Lake City after an out-of-state visit approved by his parole officer, Poulton, and learned that the police were looking for him in connection with two armed robberies. The day after Clark returned, he reported to Poul-ton at the Salt Lake County Parole office. Poulton arrested him on suspicion of the armed robberies, handcuffed him, and took him down the hall to be booked. When Clark objected during the booking to being photographed without an attorney, Poulton allegedly pushed Clark against the wall and lifted his handcuffed arms over his head, aggravating a previous back injury. Following his transportation to the jail, Clark purportedly did not receive requested medical treatment for his back for several weeks.

While detained in the jail, Clark and several other inmates were transported to court by Jorgenson. On leaving the courtroom, Clark asked to use the restroom and Jorgenson told him he would have to wait. Because of previous surgery, waiting was difficult and uncomfortable for Clark and he later doubled over in the courthouse elevator. Jorgenson allegedly grabbed Clark’s neck and chest and pushed him into the elevator wall, again aggravating his back injury. Clark required physical therapy for a year after his release from jail and sought recovery of these medical expenses as part of his damages.¹

Clark’s original complaint was filed May 12, 1986. On May 14, the district court entered an order of reference which stated:

“IT IS ORDERED that as authorized by 28 U.S.C. § 636(b)(1)(B) and the rules of this court the above entitled case is referred to the magistrate. He is directed to manage the case, to receive all motions filed, hear oral arguments hereon, to conduct evidentiary hearings when proper and make proposed findings of fact, and to submit to the undersigned judge a report and recommendation for the proper resolution of dispositive matters presented.”

Rec., vol. I, doc. 2. Pursuant to the order, the magistrate thereafter determined that Clark could proceed in forma pauperis, appointed him counsel, held scheduling and pretrial conferences, conducted an eviden-tiary hearing (described in the relevant documents as a trial), and issued a report recommending that Clark’s claims be dismissed. Clark objected to the report, which the district court summarily adopted in all respects.

II.

REFERENCE TO A MAGISTRATE

We begin our analysis of this issue by examining the jurisdiction and powers of a federal magistrate set out in 28 U.S.C. § 636 (1988). Under section 636(b)(1)(A), a judge may designate a magistrate to hear and determine all pretrial matters except for those dispositive motions specifically listed therein.² The district court reviews a section 636(b)(1)(A) determination under the same standard that an appeals court applies to a district court determination, ascertaining whether the “order is clearly erroneous or contrary to law.” Id.

Under section 636(b)(1)(B), the provision which the district court invoked in this case, a magistrate may be designated to conduct evidentiary hearings and submit reports and recommendations in three types of proceedings: 1) hearings on those dispositive motions excepted in section 636(b)(1)(A); 2) applications by criminal defendants for posttrial relief; and 3) prisoner petitions challenging conditions of confinement.³ Upon the objection by a party to the magistrate’s proposed findings and recommendations under this section, the district court is required to make a de novo determination. Id.

Section 636(b)(2) allows a judge to appoint a magistrate to serve as a special master, either pursuant to the Federal Rules of Civil Procedure or, upon consent of the parties, without regard to Rule 53(b) of the Federal Rules of Civil Procedure, Section 636(b)(3) provides that “[a] magistrate may be assigned such additional duties as are not inconsistent with the Constitution and laws of the United States.” 28 U.S.C. § 636(b)(3).

Finally, section 636(c)(1) provides that a magistrate “[u]pon consent of the parties ... may conduct any or all proceedings in a jury or nonjury civil matter and order the entry of judgment in the case, when specially designated to exercise such jurisdiction by the district court or courts he serves.” 28 U.S.C. § 636(c)(1) (emphasis added). Section 636(c)(2) sets out specific requirements regarding such consent:

“If a magistrate is designated to exercise civil jurisdiction under paragraph (1) of this subsection, the clerk of court shall, at the time the action is filed, notify the parties of their right to consent to the exercise of such jurisdiction. The decision of the parties shall be communicated to the clerk of court. Thereafter, neither the district judge nor the magistrate shall attempt to persuade or induce any party to consent to reference of any civil matter to a magistrate. Rules of court for the reference of civil matters to magistrates shall include procedures to protect the voluntariness of the parties’ consent.”

28 U.S.C. § 636(c)(2) (emphasis added). A judgment entered pursuant to Section 636(c)(1) may be appealed either to the court of appeals or to the district court, in the same manner as a district court judgment would be appealed to a court of appeals.⁴

A. Authorization

As we have noted, the district court here stated that the order of reference was made under section 636(b)(1)(B), which applies to hearings on certain dispositive motions, applications for post-conviction relief, and prisoner petitions challenging conditions of confinement. Since no dispositive motion was filed below, and since Clark was not seeking post-conviction relief, the only arguably applicable provision is the one allowing reference of prisoner challenges to conditions of confinement.

Conditions of confinement have been described as “ongoing prison practices and regulations with regard to matters such as placement in maximum security, deadlocks, unhealthy living conditions, unnecessary exposure to violence-prone inmates, overcrowded physical environments, and cruel or unusual punishment by prison authorities.” Hill v. Jenkins, 603 F.2d 1256, 1260 (7th Cir.1979) (Swygert, J., concurring). Such ongoing practices do not include “a single incident that occurred in the prison.” Id. (concurring on ground that loss of property from prison shakedown not condition of confinement). The above definition has been generally accepted by those courts addressing the issue. See, e.g., Houghton v. Osborne, 834 F.2d 745, 749 (9th Cir.1987); Hall v. Sharpe, 812 F.2d 644, 647 n. 1 (11th Cir.1987); Wimmer v. Cook, 774 F.2d 68, 74 n. 9 (4th Cir.1985); Orpiano v. Johnson, 687 F.2d 44, 47 (4th Cir.1982); but see McCarthy v. Bronson, 906 F.2d 835, 839 (2d Cir.1990). This definition, which we likewise adopt, does not encompass the two instances of the use of excessive force alleged by Clark. Those incidents, one of which occurred before Clark was even admitted to the jail, are clearly isolated events rather than part of a series of ongoing jail practices. Accordingly, the reference to the magistrate of the claims is not authorized by section 636(b)(1)(B).

The dissent’s characterization of our construction of “conditions of confinement” as unsupported by reason or authority is simply wrong. As the dissent recognizes, only two circuits have reached decisions contrary to the construction we adopt in this opinion, and only one of those circuits has explicitly disagreed with it. See McCarthy, 906 F.2d at 839. The court in McCarthy relied on Branch v. Martin, 886 F.2d (8th Cir.1989), in which the court noted in passing that “[t]he term ‘conditions of confinement’ has been interpreted expansively to include almost any prisoner § 1983 action challenging ‘the type of confinement, and matters concerning health, safety, or punishment.’ ” 886 F.2d at 1045 n. 1 (quoting Houghton v. Osborne, 834 F.2d 745, 749-50 (9th Cir.1987), and citing additional cases). However, the cases cited in Branch do not support McCarthy’s holding because they involve claims falling within our construction of the statute, with the exception of Archie v. Christian, 808 F.2d 1132 (5th Cir.1987), which does not describe the challenged conduct, and Cay v. Estelle, 789 F.2d 318 (5th Cir.1986), which does not address the condition-of-confinement issue.

Moreover, our construction is grounded, as it must be, on the plain and commonly understood meaning of the word “condition.” See Perrin v. United States, 444 U.S. 37, 42, 100 S.Ct. 311, 314, 62 L.Ed.2d 199 (1979) (“A fundamental canon of construction is that, unless otherwise defined, words will be interpreted as taking their ordinary, contemporary, common meaning.”). “Condition” is defined as “existing state of affairs,” and “a mode or state of being.” Webster’s Third New International Dictionary 473 (1981). The word thus clearly connotes an ongoing situation as opposed to an isolated incident. The court in McCarthy and the dissent here improperly defend their refusal to give effect to this plain meaning as justified by Congressional policy. The law, however, is to the contrary. “[I]t should be generally assumed that Congress expresses its purposes through the ordinary meaning of the words it uses.” Escondido Mut. Water Co. v. La Jolla Band of Mission Indians, 466 U.S. 765, 772, 104 S.Ct. 2105, 2110, 80 L.Ed.2d 753 (1984).

Finally, we note that one of Clark’s excessive force claims arises from an alleged incident occurring before he was jailed and involving his probation officer. This claim indisputably does not challenge a condition of confinement even under the dissent’s broad construction of that term.

Nor is the reference authorized under section 636(b)(3), which permits assignment to the magistrate of additional duties not inconsistent with the Constitution and federal law. This conclusion is compelled by the Supreme Court’s analysis in Gomez v. United States, — U.S. -, 109 S.Ct. 2237, 104 L.Ed.2d 923 (1989), in which the Court considered the scope of section 636(b)(3). In Gomez, a magistrate had empaneled a jury in a felony trial over the objection of the defendants. In reversing the defendants’ convictions, the Supreme Court concluded that the additional-duties clause, when considered in the context of the overall statutory scheme, does not encompass the seating of a jury in a felony trial.

In reaching this conclusion, the Court relied upon two established canons of statutory construction which apply with equal force in the instant case. First, the Court followed its “settled policy to avoid an interpretation of a federal statute that engenders constitutional issues if a reasonable alternative interpretation poses no constitutional question.” Id. 109 S.Ct. at 2241. The Court thus obviated the need to consider the constitutionality of assigning felony jury selection to a magistrate under section 636(b)(3) by determining that section 636(b)(3) itself did not authorize such an assignment. In so doing, the Court applied a second principle, stating that in interpreting a statute a court must not be “ ‘guided by a single sentence or member of a sentence, but look to the provisions of the whole law, and to its object and policy.’ ” Id. (quoting Pilot Life Ins. Co. v. Dedeaux, 481 U.S. 41, 51, 107 S.Ct. 1549, 1555, 95 L.Ed.2d 39 (1987)). The Court then reviewed the Act as a whole in light of its evolution and legislative history and concluded that while a literal reading of section 636(b)(3) in isolation would encompass the assignment of the duties at issue, “the carefully defined grant of authority to conduct trials of civil matters and of minor criminal cases should be construed as an implicit withholding of the authority to preside at a felony trial.” Id. 109 S.Ct. at 2245.

Applying these principles to the instant facts, we hold that section 636(b)(3) does not authorize a district court to designate a magistrate to conduct a hearing on a prisoner’s petition that does not challenge a condition of confinement. Gomez precludes both construing section 636(b)(3) in isolation, and upholding the assignment of additional duties on constitutional grounds without first ascertaining whether the assignment is authorized by the statute when considered as a whole. Here, section 636(b)(1)(B) carefully limits a magistrate’s authority to conduct hearings on prisoner petitions, extending that authority only to petitions challenging conditions of confinement. Under Gomez, this articulation of specific duties must be construed as implicitly withholding other duties not so specified, particularly when, as here, the contrary construction would in effect render the specific limitations a nullity.⁵ See Mountain States Tel. & Tel. Co. v. Pueblo of Santa Ana, 472 U.S. 237, 249, 105 S.Ct. 2587, 2594, 86 L.Ed.2d 168 (1985) (“elementary canon of construction that a statute should be interpreted so as not to render one part inoperative”).

Defendants argue on appeal that the reference can be upheld under section 636(c). We disagree. While section 636(c) permits a magistrate to conduct a trial in a civil matter, neither the district court nor the magistrate here purported to act pursuant to that provision. Moreover, magistrate jurisdiction to proceed under section 636(c) requires a special designation by the district court, id. § 636(c)(1), and the consent of the parties communicated to the clerk of court, id, § 636(c)(2), neither of which is present here.⁶ In finding the prerequisites for magistrate jurisdiction under section 636(c) lacking here, we join the great weight of authority and hold that consent under section 636(c)(2) must be explicit and cannot be inferred from the conduct of the parties. See Securities & Exchange Comm’n v. American Principals Holdings (In re San Vicente Medical Partners Ltd.), 865 F.2d 1128 (9th Cir.1989); Silberstein v. Silberstein, 859 F.2d 40 (7th Cir.1988); Hall v. Sharpe, 812 F.2d at 647; Wimmer, 774 F.2d at 76; Ambrose v. Welch, 729 F.2d 1084 (6th Cir.1984); but see Archie v. Christian, 808 F.2d 1132 (5th Cir.1987) (en banc).

B. Jurisdiction

Given our conclusion that the reference was unauthorized, we must consider the significance, if any, of Clark’s failure to object to proceeding before the magistrate. The majority of circuits that considered the issue prior to the Gomez decision concluded that an improper reference is a matter of jurisdiction and therefore not subject to waiver or harmless-error analysis.

For example, in Houghton v. Osborne, 834 F.2d 745, the Ninth Circuit considered facts closely analogous to those before us. There the district court had referred a prisoner’s civil rights action to a magistrate, who held an evidentiary hearing on the merits of the claim and filed proposed findings and recommendations that were adopted by the district court. On appeal, the court held sua sponte that the prisoner’s claim did not challenge a condition of confinement, and that the district court therefore “lacked the jurisdiction to refer this matter to the magistrate to conduct an evidentiary hearing on the merits of Houghton’s 1983 action.” Id. at 750. Similarly, in Hall the district court purported to refer a prisoner’s civil rights suit to a magistrate under sections 636(b)(1) and (b)(3) for a trial before an advisory jury. The magistrate issued a report recommending acceptance of the jury verdict, which the district court adopted in entering final judgment against the plaintiff. On appeal, the Eleventh Circuit concluded that “the district court’s referral of this case was not authorized by any provision of the Magistrate’s Act, 28 U.S.C. § 636, and thus the magistrate was without jurisdiction to conduct the trial.” 812 F.2d at 646; see also Lovelace v. Dall, 820 F.2d 223 (7th Cir.1987) (per curiam) (unambiguous consent of parties required for magistrate to have jurisdiction to enter final judgment under section 636(c)); Frank v. Arnold (In re Morrissey), 717 F.2d 100 (3d Cir.1983) (magistrate had no jurisdiction to hear appeal from bankruptcy court order notwithstanding parties’ express consent); Taylor v. Oxford, 575 F.2d 152 (7th Cir.1978) (magistrate had no jurisdiction over motion to dismiss for failure to state claim referred under section 636(b)(3) for final disposition pursuant to parties' stipulation and local rule); but see Archie v. Christian, 808 F.2d 1132, at 1134-35 (5th Cir.1987) (en banc) (improper reference under sections 636(b)(1)(B) and (b)(3) matter of procedure rather than jurisdiction).⁷

In Gomez, the defendants had objected to the assignment to the magistrate, but they made no special claim of prejudice on appeal and the government therefore contended that the error was harmless. The Supreme Court rejected this argument, stating that “harmless-error analysis does not apply in a felony case in which, despite the defendant’s objection and without any meaningful review by a district judge, an officer exceeds his jurisdiction by selecting a jury.” 109 S.Ct. at 2248 (emphasis added).

Notwithstanding this language, courts subsequent to Gomez have varied in their assessment of the relevance of that opinion to cases in which the defendant did not object to the magistrate’s unauthorized acts. In United States v. Mang Sun Wong, 884 F.2d 1537, 1544-46 (2d Cir.1989) (order on petition for rehearing), cert. denied, — U.S. -, 110 S.Ct. 1140, 107 L.Ed.2d 1045 (1990), a majority of the panel distinguished Gomez, read it narrowly, and held without analyzing the jurisdictional issue that Gomez does not require reversal when the defendant consented to the magistrate’s improper exercise of power. Judge Altimari dissented, concluding that the issue is one of jurisdiction, and that consent is therefore irrelevant because it “cannot enlarge those powers of office not granted by the Federal Magistrates Act.” Id. at 1546. See also United States v. Mussacchia, 900 F.2d 493 (2d Cir.1990) (following Mang Sun Wong, one judge dissenting).

In United States v. France, 886 F.2d 223 (9th Cir.1989), cert. granted, — U.S. -, 110 S.Ct. 1921, 109 L.Ed.2d 285 (1990), however, the court held Gomez applicable to all cases pending on direct appeal, including those in which the defendant did not object to the magistrate’s jury selection. The court did not address the jurisdictional issue, grounding its decision instead on its conclusion that Gomez announced a new rule appropriate for retroactive application, and that under Ninth Circuit precedent France had not waived his entitlement to the rule by failing to object at trial. The court did emphasize several times the Supreme Court’s references in Gomez to the magistrate’s lack of “jurisdiction” and “power.” Id. at 226 & n. 1.

In United States v. Wey, 895 F.2d 429 (7th Cir.1990), the Seventh Circuit held that subject matter jurisdiction is not involved and that the unauthorized exercise of power was therefore subject to waiver. The case is thus contrary to the Seventh Circuit’s decisions in Lovelace, 820 F.2d at 225-26 & n. 3, and Taylor, 575 F.2d at 154, in which the court held that the magistrate’s power under the Act is a matter of jurisdiction and that the parties cannot confer jurisdiction which the magistrate does not possess by failing to object. The court in Wey relied in part on the First Circuit decision in United States v. Lopez-Pena, 890 F.2d 490 (1st Cir.1989), which was withdrawn upon the grant of rehearing en banc.

In its subsequent en banc opinion, the First Circuit emphasized the jurisdictional language in Gomez, and then agreed with France, 886 F.2d 223, that Gomez must be applied where the magistrate was permitted to empanel the jury, notwithstanding the failure to object. See United States v. Martinez-Torres, 912 F.2d 1552 (1st Cir.1990). In so doing, the First Circuit expressly disapproved of the opinions in Wey and Mang Sun Wong, and criticized the discussion of consent in Virgin Islands v. Williams, 892 F.2d 305, 309-12 (3d Cir.1989), cert. denied, — U.S. -, 110 S.Ct. 2211, 109 L.Ed.2d 537 (1990).

We also disagree with the analysis in Williams. There, the court appeared to hold that the issue of the magistrate’s power is a jurisdictional matter but nonetheless is subject to waiver. In so doing, the court construed section 636(b)(3) in isolation in direct contradiction to the analysis in Gomez, held that the section authorizes the very reference Gomez specifically held to be unauthorized, and then decided the constitutional issue Gomez deliberately avoided. The concurrence in Williams concluded that, although the magistrate’s power raises an issue of jurisdiction, Gomez does not preclude plain error analysis, and the magistrate’s unauthorized exercise of power was not plain error.

In our view, the Supreme Court’s language and analysis in Gomez, and the language of the Act itself, compel the conclusion that a magistrate’s power under the Act is a jurisdictional issue not subject to waiver. The Act speaks in terms of a magistrate’s exercise of jurisdiction, see 28 U.S.C. §§ 636(c)(1) and (2), and Gomez repeatedly refers to a magistrate’s jurisdiction. In Parts III and IV of Gomez, the Court traced the evolution of the powers of federal magistrates and reviewed the current authority conferred by the Federal Magistrates Act of 1979. See 109 S.Ct. at 2242-47. That discussion is couched in terms of Congressional grants of and limitations upon jurisdiction.

The court in Wey discounted the obvious impact of the use of the term “jurisdiction” by Congress and the Supreme Court. Instead, the court adopted a plain error rule, observing that although the magistrate’s conduct at issue was unauthorized, the district court had subject matter jurisdiction under the relevant jurisdictional statutes. This result ignores the fact that while the limitations in the Magistrate Act do restrict a magistrate’s authority to act in a case properly before the district court, the Act also restricts the district court’s power to refer a matter to a magistrate. Congres-sionally imposed limits on the exercise of judicial power other than the delineation of subject matter jurisdiction are nonetheless jurisdictional. See Lauf v. E.G. Skinner & Co., 303 U.S. 323, 330, 58 S.Ct. 578, 582, 82 L.Ed. 872 (1938); 13 C. Wright, A. Miller & E. Cooper, Federal Practice and Procedure § 3526 at 227-28 (2d ed. 1984).

“[T]he jurisdiction of a magistrate to decide a case is not based solely on the consent of the parties, but derives from a proper designation by the district court. Because district court jurisdiction is statutory, its ability to make a proper designation of, and thereby to confer jurisdiction on, a magistrate is also a creature of statute.”

In re Morrissey, 717 F.2d at 102.

We simply cannot accept an analysis under which parties by their conduct may extend the jurisdiction of both the magistrate and the district court beyond that established by Congress. We therefore hold that the magistrate in this case was without jurisdiction to hear the excessive force claims.⁸

III.

Accordingly, we vacate the judgment dismissing Clark’s claims and remand to the district court for further proceeding consistent with this opinion.⁹

1 . Clark spent nine months in the jail pending disposition of the charges against him, one of which was dismissed after his acquittal on the other. During his incarceration, his truck was repossessed, and he could not attend school for which he had already paid tuition. Because of this loss of student status, he also lost the deferral of his student loan repayment. In addition to his medical expenses, Clark sought recovery for these losses, as well as injunctive relief relating to his parole and to the jail’s magazine subscription policy. We express no opinion on the relief Clark seeks.

2 . Section 636(b)(1)(A) provides:

"[A] judge may designate a magistrate to hear and determine any pretrial matter pending before the court, except a motion for injunc-tive relief, for judgment on the pleadings, for summary judgment, to dismiss or quash an indictment or information made by the defendant, to suppress evidence in a criminal case, to dismiss or to permit maintenance of a class action, to dismiss for failure to state a claim upon which relief can be granted, and to involuntarily dismiss an action."

28 U.S.C. § 636(b)(1)(A).

3 . Section 636(b)(1)(B) provides:

‘‘[A] judge may also designate a magistrate to conduct hearings, including evidentiary hearings, and to submit to a judge of the court proposed findings of fact and recommendations for the disposition, by a judge of the court, of any motion excepted in subpara-graph (A), of applications for posttrial relief made by individuals convicted of criminal offenses and of prisoner petitions challenging conditions of confinement.”

28 U.S.C. § 636(b)(1)(B).

4 . In addition to the provisions discussed above, section 636(a)(3) grants magistrates the power to conduct trials under 18 U.S.C. § 3401 (1988). Section 3401 gives a magistrate jurisdiction to try and sentence defendants accused of misdemeanors upon special designation by the district court and the written consent of the defendant.

5 . The dissent cites Marvel v. United States, 719 F.2d 1507 (10th Cir.1983), for the proposition that "the majority’s construction of the statute does not avoid deciding a constitutional issue, for this court has already held that Article III allows a magistrate to preside over a civil matter so long as the district court reviews the matter de novo." Dissent at 1436 n. 4. Marvel is totally inapposite inasmuch as the parties there consented to trial before the magistrate. See 719 F.2d at 1512 ("[W]e hold there is ample statutory authority under 28 U.S.C. § 636(h)(2) to refer a civil case to a federal magistrate for trial on the merits, provided the parties consent -to such a procedure.”)

6 . Section 636(c)(2) also states that "[r]ules of court for the reference of civil matters to magistrates shall include procedures to protect the voluntariness of the parties’ consent.” Our examination of the Civil Rules of Practice of the United States District Court for the District of Utah reveals no provision for the reference of civil trials to a magistrate. To the contrary, magistrates do not generally even conduct final pre-trial conferences, see Rule 9(d), and are specifically precluded from entering any order dispositive of a substantive issue in the case, see Rule 9(i).

7 . The dissent asserts that our reliance on Houghton, Lovelace, and In re Morrissey is questionable because those cases do not specifically address the failure to object to an unauthorized reference. The short answer to the dissent's objection is that a determination that the issue is jurisdictional simply obviates the need to address a failure to object. Lack of subject-matter jurisdiction renders lack of objection irrelevant. See, e.g., 15 C. Wright, A. Miller & E. Cooper, Federal Practice & Procedure § 3801 at 7 (2d ed. 1986) (subject matter jurisdiction cannot be waived by the parties).

8 . We recognize that two of Clark’s claims, his allegations of denial of medical treatment while in the jail and his challenge to the jail magazine policy, do challenge conditions of confinement. However, those claims were consolidated by agreement of the parties with Clark’s excessive force claims. Given our conclusion that the parties may not consent to the magistrate's exercise of a power withheld by Congress, the parties’ consent here to consolidation cannot vest the magistrate with jurisdiction over claims not referable to him.

9 . We note Clark’s argument that the district court did not make the required de novo review of those portions of the magistrate’s report to which Clark objected. In view of our conclusion that this case must be remanded in any event, we need not address this argument other than to observe that our opinion in Gee v. Estes, 829 F.2d 1005, 1008-09 (10th Cir.1987), is available for the guidance of the court on this issue on remand.
