Pursuant to rule 101 of the Texas Rules of Appellate Procedure, a majority of the justices who participated in our February 27, 1987 opinion have reconsidered that opinion, and after such reconsideration find that our opinion should be corrected to read as follows:
Lanny Royce Omura appeals the trial court’s order denying his writ of habeas corpus by which he sought to avoid extradition to the State of Utah. In his fourth point of error, appellant contends that the Dallas County Magistrates Act2 is unconstitutional. We hold that the Magistrates Act was not properly complied with; accordingly, we do not address the constitutionality of the Magistrates Act. See Smith v. State, 658 S.W.2d 172, 174 (Tex.Crim.App.1983) (the constitutionality of a statute will not be determined unless necessary to decide the case in which the issue is raised).
The Dallas fCounty Magistrates Act provides for the appointment of magis*767trates to assist the district courts in the disposition of criminal cases. Howard v. State, 690 S.W.2d 252, 255 (Tex.Crim.App.1985). The magistrates act only as agents of the district courts and have no authority of their own. Id. They merely assist the district courts by processing those matters not requiring ultimate judicial determinations. Id.
The record in the present case shows that appellant signed a waiver of his right to have his habeas corpus application heard by a district judge and that he requested that the matter be heard and determined by a magistrate.3 Accordingly, this matter was referred to the magistrate for hearing. The original transcript on appeal in this case contains an “Order Adopting Actions of the Magistrate,” which was signed by the district court judge on July 2, 1986. The order recites that the court reviewed the actions taken by the magistrate, and that the court specifically adopts and ratifies those actions. This court, however, found nothing in the transcript which would show what materials the trial court had before it in making its determination of whether to adopt the actions of the magistrate. We, therefore, requested the district clerk to prepare a supplemental transcript containing all materials the district court had before it on or before July 2, 1986 in reviewing the actions taken by the magistrate. On September 17, 1986, this court received a supplemental transcript. That supplemental transcript contained only an order which recited:
[T]his Court finds that no supplementation can be made ... at the conclusion of the extradition hearing upon Appellant’s application for writ of habeas corpus the following papers, already included in the record on appeal herein, were transmitted to the Clerk of this Court: the Appellant’s Writ of Habeas Corpus, the executive warrant, the docket sheet, and the request for referral to Magistrate and order of referral, referring said cause to the Magistrate for hearing and determination therein. Upon transmittal, the Clerk of this Court prepared and issued the order adopting actions of the Magistrates [sic] and the judgment of the Court committing the Appellant to the custody of the Sheriff for delivery to the demanding state.
The order further recited that the statement of facts from the extradition hearing and the documentary evidence introduced at that hearing had been prepared by the court reporter and filed with the district court on July 17, 1986, fifteen days after the “Order Adopting Actions of the Magistrate” was signed by the court.
Absent a showing to the contrary, there is a presumption of regularity of proceedings. Ex parte Stacey, 709 S.W.2d 185, 189 (Tex.Crim.App.1986); Thompson v. State, 641 S.W.2d 920, 921 (Tex.Crim. App.1982). This presumption can, however, be overcome. Ex parte Stacey, 709 S.W.2d at 189. In the present case, the presumption has been overcome, as it is clear that the trial court could not and did not review the actions of the magistrate.
Section 54.311 of the Magistrate’s Act provides: “At the conclusion of the proceedings, a magistrate shall transmit to the referring court any papers relating to the case, including the magistrate’s findings, conclusions, orders, recommendations, or other action taken.” Section 54.312 provides:
(a) A referring court may modify, correct, reject, reverse, or recommit for further information any action taken by the magistrate.
(b) If the court does not modify, correct, reject, reverse, or recommit an action of the magistrate, the action becomes the decree of the court.
The act is mandatory, since a magistrate acts only as the agent of the district court, under proper supervision by the court. Kelley v. State, 676 S.W.2d 104, 107 (Tex.Crim.App.1984). No act of the magistrate is legally binding unless and until the magistrate’s actions are adopted by the refer*768ring court. Id. Magistrates are not judges, but are merely agents of judges appointed to assist the district judges of Dallas County in certain limited matters. Id. It is clear from the wording of the act that it is mandatory that the district judge review the actions taken by the magistrate. To review the magistrate’s actions the district judge must have before him the record and any exhibits from the proceeding. Only after a careful review of the record and any exhibits is the district judge in a position to “modify, correct, reject, reverse, or recommit for further information any action taken by the magistrate.”
The record in the present case affirmatively shows that the district judge did not review the actions taken by the magistrate, contrary to the recitation in the order. There were no findings, no conclusions, no orders, and no recommendations made by the magistrate, from which the district court could have reviewed the actions taken by the magistrate.4 Nor was the evidence heard by the magistrate transcribed before the magistrate’s actions were adopted by the district court. Accordingly, we hold that the Magistrate’s Act was improperly applied. In view of our disposition of this case, we do not address appellant’s remaining contentions.
We reverse the judgment of the trial court and remand the cause to the trial court for further proceedings consistent with this opinion.
. TEX.GOV’T CODE ANN. § 54.301, et seq. (Vernon 1986).
. In view of this waiver, we do not address the question of whether an extradition habeas corpus proceeding is a proper proceeding for referral to a magistrate and this opinion is not to be read as so holding.
. In Kelley v. State, 676 S.W.2d 104, 107 (Tex.Crim.App.1984), the court cautioned that Dallas County needed to adopt a clear mechanism for transmitting all papers related to the case and for noting the recommendations and findings of the magistrate. Id. at 108, n. 5.
