OPINION
Don Davis, Jr. appeals an order modifying a judgment committing Davis as a sexually violent predator (“SVP”). In four issues, Davis contends: (1) the trial court erred in permitting the Council on Sex Offender Treatment (the “Council”), a state agency not authorized by statute to sue or be sued, to intervene as a party in the commitment action; (2) if construed to grant the Council unrestricted discretion in imposing conditions on civilly committed individuals, Chapter 841 of the Texas Health and Safety Code is an unconstitutional delegation of legislative authority under Article II, Section 1 of the Texas Constitution; (3) if the Council had standing in these proceedings, the trial court abused its discretion in refusing to join the Council as a party to the suit; and (4) if the Council is recognized as a distinct legal entity, the trial court erred in permitting the Council to intervene because the Council could not have brought the action in its own name.
The State, acting through the Special Prosecution Unit — Civil Division, filed its original petition to commit Davis as a sexually violent predator, or SVP, in June 2007. Davis filed a pre-trial motion for “Joinder of Persons Needed for Just Adjudication” in which he sought to join the Council on Sex Offender Treatment as a third-party defendant, alleging that the *126 State Prosecuting Attorney lacked authority to control the case without the Council’s approval. The Council filed an answer and a motion to dismiss. The trial court dismissed the Council on September 5, 2007.
The trial court signed an agreed final order of commitment on October 17, 2007. The judgment required that Davis “participate in and comply with a specific course of treatment^]” The judgment ordered that a treatment plan be developed by the treatment provider with the approval of the Council.
On November 14, 2007, Davis filed a motion to modify the judgment. In his motion, Davis complained that he was not provided fair notice of the specific treatment plan he is required to follow, and complained of two items on his proposed treatment plan, namely, the requirement that he not possess or display pictures of children without prior approval from the case manager and treatment provider, and that he agree to audio or video recording of his sessions.
On January 9, 2008, the Council on Sex Offender Treatment filed a motion to modify the final judgment that sought to modify Davis’s commitment requirements by requiring Davis to participate in and comply with a specific course of treatment determined by the Council on Sex Offender Treatment or Davis’s case manager. 1
The trial court conducted a hearing on both motions. The Council’s representative at the hearing suggested that Davis’s motion was premature because his treatment program would not be developed and individualized until Davis’s release from prison, approximately six months after the date of the hearing. The Council suggested the judgment should specify that the Council was the entity that would determine the specific course of treatment Davis would be required to follow. In a brief filed with the trial court, Davis argued that the Council lacks standing to file a motion to modify the commitment order. Davis also argued that the proposed change was redundant because language elsewhere in the order required that a treatment plan be developed. On February 11, 2008, the trial court signed a “Modified Final Judgment and Order of Civil Commitment” that required Davis to “participate in and comply with a specific course of treatment as determined by the Council on Sex Offender Treatment[;]” and “follow the appropriate written supervision requirements of the CSOT (Council on Sex Offender Treatment) and/or the Case Manager[.]”
In his first issue, Davis contends the Council is simply an agency of thé State of Texas, not empowered to sue or be sued and thus lacking standing to file and present a motion to amend the judgment of civil commitment. The Council is within the Texas Department of State Health Services. See Tex. Coc.Code Ann. § 110.051 (Vernon Supp. 2008). “The Council on Sex Offender Treatment is responsible for providing appropriate and necessary treatment and supervision through the case management system.” Tex. Health & Safety Code Ann. § 841.007 (Vernon Supp. 2008). The provisions for implementing the Council’s duties are located in Chapter 810 of the Texas Administrative Code. See 22 Tex. Admin. Code §§ 810.1-810.275 (2009). The Council contracts for treatment and supervision service providers. See 22 Tex. Admin.Code *127 § 810.181. A case manager is a person employed by or under contract with the Council to perform duties related to outpatient treatment and supervision of a person committed under Chapter 841. Tex. Health & Safety Code Ann. § 841.002(3) (Vernon Supp. 2008). A case manager reports directly to the Council through the Council’s executive director or the director’s designee, and is authorized to communicate with law enforcement, prosecutors, and the judge having jurisdiction over the person’s commitment, and to make recommendations to the judge concerning whether to allow a change of the committed person’s residence or “any other appropriate matters” relating to the SVP’s civil commitment. See Tex. Health & Safety Code Ann. § 841.083(e) (Vernon Supp. 2008); 22 Tex. Admin. Code § 810.182. Thus, the statutory and administrative mechanism for SVP commitments contemplates communication between the judge and the Council through the Council’s agent. There is, however, no provision in either Chapter 841 of the Health and Safety Code or Chapter 810 of the Texas Administrative Code for the Council to participate as a party in a commitment proceeding. Rather, the parties to the commitment proceeding are the State, acting through the civil division of the Special Prosecution Unit, and the committed person, represented in this instance by the State Counsel for Offenders. The Council’s function is not adversarial, but is administrative and regulatory. See Tex. Ocg Code Ann. § 110.151 (Vernon Supp. 2008). 2
Davis argues that the Council, by filing a motion through its assistant general counsel, “was in fact initiating legal action” without the consent of the Attorney General. In this case, however, the legal action is the commitment proceeding that was initiated through the civil division of the Special Prosecution Unit, which is by statute responsible for initiating and pursuing civil commitment proceedings under Chapter 841. See Tex. Health & Safety Code Ann. § 841.004 (Vernon Supp. 2008). The Special Prosecution Unit participated in the hearing that resulted in the order from which Davis has appealed. Furthermore, the trial court retains jurisdiction over the committed person, and the requirements imposed in an order of commitment “may be modified at any time after notice to each affected party to the proceedings and a hearing.” Tex. Health & Safety Code Ann. § 841.082(d), (e) (Vernon Supp. 2008). The trial court retained both personal jurisdiction over Davis and subject matter jurisdiction over the civil commitment regardless of the presence or lack of authority for the Council to file a formal motion in district court. See id. Because the trial court retains jurisdiction and the power to modify the commitment requirements at any time, the trial court could do so regardless of whether the Council (or the State through counsel for the Council) lacked standing to file formal pleadings in the case.
Having determined that the trial court had the authority to modify the order committing Davis to out-patient treatment and supervision, we must determine whether our appellate jurisdiction extends to this appeal. The trial court modified
*128
that part of the judgment that imposed the commitment requirements set forth in Section 841.082(a) of the Health and Safety Code.
See
Tex. Health & Safety Code ANN. § 841.082(a). Those requirements may be modified at any time, upon notice and a hearing. Tex. Health & Safety Code Ann. § 841.082(e). We considered a similar issue when a committed person filed notice of appeal from a commitment order signed following biennial review of the order of commitment.
See In re Commitment of Richards,
Here, the modification concerns the requirement found in Section 841.082(a)(4).
See
Tex. Health & Safety Code Ann. § 841.082(a) (“The requirements shall include: ... (4) requiring the person’s participation in and compliance with a specific course of treatment!)]”). Both this case and
Richards
concern a judgment modifying one of the mandatory requirements
for
commitment of a sexually violent predator. Two features distinguish
Richards
and this case. In
Richards
the trial court modified the commitment terms following the biennial review.
Richards,
Significant in our analysis in
Richards
was the fact that Chapter 841 does not expressly provide for appealing a biennial review order.
Richards,
This case presents features that are generally appealable and were not present in
Richards.
In
Richards,
we noted that the biennial review order lacked language indicating the trial court’s intention that it function as a final judgment.
Id.
at 786. In Davis’s case, however, the trial court did expressly state that it intended that the order function as a final judgment.

See Lehmann,
Davis contends the trial court erred in allowing the Council to “intervene as a separate and distinct party to this action.” This commitment proceeding was brought by the civil division of the Special Prosecution Unit, in accordance with Section 841.004.
See
Tex. Health & Safety Code Ann. § 841.004. Pursuant to Section 841.082, the trial court retained jurisdiction over Davis and was statutorily authorized to modify the requirements imposed by the commitment judgment. Tex. Health & Safety Code Ann. § 841.082(d),(e) (Vernon Supp. 2008). A trial court may reconsider an order as long as a case is still pending.
See generally In re Baylor Med. Ctr. at Garland,
In his second issue, Davis contends Chapter 841 is an unconstitutional delegation of legislative authority. See Tex. Const, art. II, § 1; Tex. Const, art. Ill, § 1. Davis did not present his separation of powers challenge to the trial court. Accordingly, the issue is not preserved for appellate review. Tex.R.App. P. 33.1. We overrule issue two.
Davis’s third issue argues that, if the Council has the standing to pursue a motion to modify the judgment, then the trial court abused its discretion in refusing Davis’s request to join the Council as a party. Davis filed his request to join the Council before the trial court signed the original judgment in the case. Therefore, the issue is one that could have been raised on appeal from the judgment signed October 17, 2007. Because Davis did not appeal that judgment, no complaint may be heard on appeal that could have been presented in an appeal from the original judgment. Tex.R. Civ. P. 329b(h). We overrule issue three.
*130
Davis’s final issue contends the trial court erred in permitting the Council to intervene after Davis’s initial commitment to outpatient sex offender treatment. Citing
First Alief Bank v. White,
Davis argues that the motion, having been filed after judgment, was filed too late to effectively bring the Council into the case.
See First Alief Bank v. White,
AFFIRMED.
Notes
. The judgment required Davis to "participate in and comply with a specific course of treatment[.]” The Council requested the order be changed to require Davis to "follow appropriate written supervision requirements of the Council on Sex Offender Treatment and/or the case manager.”
. Section 110.151, Texas Occupations Code, provides as follows:
The council shall: (1) develop treatment strategies for sex offenders by evaluating instate and out-of-state programs for sex offender treatment; (2) set standards for treatment of sex offenders that must be met by sex offender treatment providers to be eligible for a license under this chapter; and (3) recommend to licensing and regulatory boards and to the directors of current programs methods of improving programs to meet council standards.
