OPINION
On February 19, 2004, a magistrate judge entered an order authorizing the involuntary administration of medication to Abisai Rivera-Guerrero (hereafter “Rivera”), for the purpose of making Rivera competent to stand trial. On March 10, 2004, the district court denied Rivera’s motion to reconsider the magistrate judge’s decision. Rivera appeals the district court’s decision, arguing that the magistrate judge lacked authority to issue the final order and that, on the merits, the order violated his constitutional rights. We do not reach the merits because we hold that the magistrate judge did lack authority to issue the final order. Accord *1066 ingly, we vacate the district court’s order and remand for further proceedings consistent with this opinion.
I. Factual and Procedural History
Rivera was arrested on September 14, 2003, for illegal reentry after deportation, in violation of 8 U.S.C. § 1326(a). After Rivera failed to appear before the magistrate judge for his preliminary hearing, the magistrate judge granted his counsel’s request for a psychological evaluation pursuant to 18 U.S.C. § 4241(b). On October 30, 2003, the magistrate judge held a competency hearing, at which she reviewed the psychological evaluation and determined that Rivera was not competent to stand trial. Accordingly, she ordered him committed to the custody of the Attorney General pursuant to 18 U.S.C. § 4241(d). Rivera was sent to a federal treatment facility in Springfield, Missouri, and has been held there since November 25, 2003.
On February 6, 2004, the magistrate judge held a status hearing in which she heard testimony from Rivera’s treating psychiatrist, Dr. Robert Sarrazin, M.D., and his treating psychologist, Dr. David Mrad, Ph.D. The doctors notified the magistrate judge that Rivera was refusing his medication. They reported several instances of hostility and disorganized thinking during Rivera’s time in custody. Dr. Mrad reported that Rivera was not considered sufficiently dangerous to warrant immediate emergency medication, because he was being held in a locked ward in a locked room. However, the doctor testified that in his opinion, Rivera needed forced medication in order to make him competent for trial and in order to have him around the other inmates.
In response to this testimony, the magistrate judge scheduled a hearing for February 19, 2004, in order to determine whether to issue an order for involuntary medication. At the hearing, the magistrate judge questioned the doctors at length about each of the factors delineated by the Supreme Court in
Sell v. United States,
Rivera appealed the magistrate judge’s order to the district court. In his appeal, he argued that the magistrate judge lacked both constitutional and statutory authority to issue an order for involuntary medication, an argument he had not raised before the magistrate judge. He also contested the merits of the magistrate judge’s decision.
In a written order filed on March 10, 2004, the district court ruled that the magistrate judge’s authority to issue the order for involuntary medication did not raise constitutional problems, nor did it exceed the statutory bounds of the Federal Magistrates Act, 28 U.S.C. §§ 631-639 (2000) (hereafter “the Act”). The district court adopted the government’s argument that the involuntary medication order was a “non-dispositive collateral matter,” and therefore it could be delegated to the magistrate judge without violating Article III of the Constitution. In addition, the court reviewed the provisions of the Act, and found that the order fell within its bounds, as a pretrial matter that was not one of the eight dispositive motions excepted from *1067 the Act. The court found the appropriateness of this delegation confirmed by Local Criminal Rule 57.4.C.9, which authorizes the magistrate judge to “[h]ear motions and enter orders for examinations to determine mental competency under 18 U.S.C. § 4241.”
The district court then reviewed the magistrate judge’s determination for clear error. It held that the magistrate judge’s finding that the government had provided clear and convincing evidence in support of each of the four Sell factors was not contrary to the law. It also held that Rivera’s due process rights were not violated by the magistrate judge’s denial of the request for continuance. Accordingly, the district court denied the motion to reconsider the magistrate judge’s order.
Rivera timely appealed.
II. Discussion
We review the delegation of authority to a magistrate judge de novo.
United States v. Gomez-Lepe,
A. Statutory Analysis
Section 636 of the Federal Magistrates Act delineates the jurisdiction and powers of magistrate judges. 28 U.S.C. § 636. Section 636(b)(1)(A) permits the district court to designate any pretrial matter to the determination of the magistrate judge, with the exception of eight types of motions. 1 Section 636(b)(1)(B) allows the magistrate judge to conduct hearings and submit proposed findings of fact and recommendations to the district court on the excepted motions listed in § 636(b)(1)(A). 2 Finally, § 636(b)(3) permits a district court judge to assign the magistrate judge any additional duties not inconsistent with the Constitution and the laws of the United States.
The district court concluded that, because § 636(b)(1)(A) does not expressly preclude magistrate judges from issuing orders for involuntary medication, such orders are pretrial matters that can be delegated to magistrate judges under the Act. Although supported by a literal reading of the text of the statute, this reasoning runs counter to our precedent interpreting the Act. With regard to § 636(b)(1)(A), we have indicated that the eight exceptions are not an exhaustive list of all the pretrial matters that are excepted from the magistrate judge’s authority. In
Maisonville v. F2 America, Inc.,
[Sjection 636(b)(1)(A) lists those motions which may not be determined by a magistrate. Accordingly, any motion not listed, nor analogous to a motion listed in this category, falls within the non- *1068 dispositive group of matters which a magistrate may determine.
Id. at 747-48 (emphasis added).
Thus, in contrast to the district court’s conclusion,
Maisonville
suggests that the list of excepted pretrial matters can be expanded to include other, analogous motions as well. Two other circuits have explicitly adopted this interpretation of § 636(b)(1)(A).
See Massey v. City of Fernmdale,
The Supreme Court has also indicated that the listed exceptions from § 636(b)(1)(A) are not exclusive. In
Gomez v. United States,
[Congress] did not identify the selection of a jury as either a “dispositive” matter covered by § 636(b)(1)(B) or a “nondis-positive” pretrial matter governed by § 636(b)(1)(A). To the limited extent that it fits into either category, we believe jury selection is more akin to those precisely defined, “dispositive” matters for which subparagraph (B) meticulously sets forth a de novo review procedure.
Id.
at 873-74,
The foregoing discussion demonstrates that there is significant precedent to support the conclusion that we do not simply look to the list of excepted pretrial matters in order to determine the magistrate judge’s authority. Instead, we must look to the effect of the motion, in order to determine whether it is properly characterized as “dispositive or non-dispositive of a claim or defense of a party.” Maisonville,
The district court erred when it concluded that the involuntary medication order was not a final order and was therefore not dispositive. The court based its analysis of the non-dispositive nature of the order on the Sell Court’s statement that an order to forcibly medicate “is completely separate from the merits of the action.”
Sell,
*1069
Furthermore, this disputed question is properly considered “a claim or defense of a party.”
Maisonville,
We conclude that an order authorizing involuntary medication is dispositive of a claim or defense of a party, and therefore, under
Maisonville,
it is not among the pretrial matters that can be fully delegated to the magistrate judge under § 636(b)(1)(A). This conclusion is further supported by
Gomez’s
discussion of the provision, in which the Court noted its agreement with the Eighth Circuit’s holding that “ ‘[sjubparagraph (A) was plainly intended for less important matters than voir dire.’ ”
Gomez,
B. The Principle of Constitutional Avoidance
In addition to the foregoing statutory analysis, there are also serious constitutional concerns that arise with the delegation of involuntary medication orders to magistrate judges. In
Gomez,
the Supreme Court emphasized that the Act must be read with its legislative history in mind, which contained assurances that “magistrates’ adjudicatory jurisdiction had been circumscribed in the interests of policy as well as constitutional constraints.”
In
Peretz v. United States,
Applying the principle of constitutional avoidance to the case at hand strongly supports our conclusion that, like jury selection, involuntary medication is not the type of pretrial matter that Congress intended the Act to delegate to magistrate judges. It is well-established that “involuntary medical treatment raises questions of clear constitutional importance.”
Sell,
Local Criminal Rule 57.4.C.9 does not alter our conclusion that the magistrate judge exceeded her constitutional and statutory bounds by issuing a final order for involuntary medication. The Rule permits the magistrate judge to hear motions and enter orders for examinations to determine mental competency under 18 U.S.C. § 4241. There is nothing in the text of this rule that allows magistrate judges to issue orders authorizing involuntary medication. The rule allows the magistrate judge to order an examination to determine competency, a decision that has no dispositive effect and is therefore not reserved for Article III judges.
C. Proposed Findings and Recommendations
We find no statutory or constitutional concerns raised by allowing the magistrate judge to submit proposed findings and recommendations on the involuntary medication determination to the district court for de novo review. As previously discussed, although an order for involuntary medication is not one of the listed exceptions in subparagraph (A) for which delegation with de novo review is permitted under subparagraph (B), it is analogous to the types of dispositive motions excepted by (A), and it follows that it is encompassed by (B). Alternatively, it could be considered an additional duty under § 636(b)(3).
Raddatz
makes clear that the delegation to magistrate judges of matters that implicate constitutional rights for proposed findings and recommendations is constitutional so long as the findings and recommendations are subject to de novo review by an Article III judge.
See Raddatz,
*1071
Thus, the problem with the order of the district court before us boils down to a matter of standard of review. Had the district court applied de novo review to the magistrate judge’s order, we would have no need to remand the case.
See United States v. Weissberger,
In light of the accelerated nature of this appeal, we remand for the district court to apply de novo review to the magistrate judge’s unauthorized order. By doing so, the district court should treat the magistrate judge’s “order” as proposed findings and recommendations. Of course, in exercising its independent judgment, “[t]he district judge is free to follow [the magistrate judge’s recommendation] or wholly to ignore it, or, if he is not satisfied, he may conduct the review in whole or in part anew.”
Mathews v. Weber,
Finally, we note that in
Sell,
the Court appears to have reviewed an order by a magistrate judge that was affirmed by the district court and then appealed.
Sell,
III. Conclusion
Our case law — as well as that of other circuits and the Supreme Court — makes clear that an involuntary medication order is not the type of pretrial matter the Federal Magistrates Act permits district courts to delegate to the final authority of magistrate judges. Furthermore, there is significant Supreme Court precedent holding that there are important constitutional rights at stake for Rivera in determining whether the state can administer involuntary medication for the purpose of making him competent to stand trial. There is equally significant Supreme Court precedent underscoring the constitutional requirement that Article III judges are the ultimate decision makers on matters involving substantial constitutional questions. In light of these statutory and constitutional lines of precedent, we hold that *1072 magistrate judges lack authority to issue final orders authorizing the involuntary administration of medication. Accordingly, we vacate the district court’s order and remand this case for further proceedings consistent with this opinion.
VACATED and REMANDED.
Notes
. The eight exceptions are motions 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).
. Section 636(b)(1)(B) also permits magistrate judges to make findings and recommendations for applications for post-trial relief by individuals convicted of criminal offenses and for prisoner petitions challenging conditions of confinement.
. In Rivera’s case, neither the district court nor the government argued that the magistrate judge’s authority to order involuntary medication lies in the additional duties clause, § 636(b)(3). Even if they had, this argument would be unavailing based on our discussion of the doctrine of constitutional avoidance.
. There is no evidence that Rivera was ever given the opportunity to object or consent to the magistrate judge's authority, and the government does not argue that the order is permissible due to some form of consent from Rivera. Therefore, we do not reach the question of whether a defendant who has been found not competent to stand trial could give meaningful consent to the magistrate judge's authority to issue a final order authorizing involuntary medication.
