OPINION
This is an interlocutory appeal from an order denying Appellant CTL/Thompson Texas, LLC’s motion to dismiss Appellee Starwood Homeowner’s Association, Inc.’s claims based on Starwood’s alleged failure to comply with the certificate of merit requirements of chapter 150 of the Texas Civil Practice and Remedies Code. After the trial court denied CTL’s motion to dismiss and after CTL filed its notice of appeal perfecting this appeal, Starwood filed a nonsuit in the trial court, nonsuiting all of its claims against all defendants, including CTL. Starwood subsequently filed in this court an emergency motion to dismiss this appeal, arguing that as a result of its nonsuit, no justiciable controversy currently exists between the parties, this appeal is now moot, and this court possesses no jurisdiction over the appeal.
CTL filed a response to Starwood’s emergency motion to dismiss this appeal. CTL argues that its motion to dismiss Starwood’s claims for Starwood’s alleged failure to comply with the statutory certificate of merit requirements is, in fact, a motion for sanctions (seeking the sanction of dismissal with prejudice) and that, accordingly, it constitutes an affirmative claim for relief that survives Starwood’s nonsuit. 1
*856
Pursuant to Texas Rule of Civil Procedure 162, a plaintiff possesses an absolute right to nonsuit claims, except that any dismissal “shall not prejudice the right of an adverse party to be heard on a pending claim for affirmative relief.” Tex.R. Civ. P. 162. Generally, the nonsuit of the underlying case renders a pending appeal moot, resulting in the dismissal of the appeal.
Carter v. Stevens Transp., Inc.,
As mentioned above, CTL contends that its motion to dismiss Starwood’s claims based on Starwood’s purported failure to comply with the statutory certifícate of merit requirements is a claim for affirmative relief (akin to a motion for sanctions) that survives the nonsuit. By way of analogy, CTL points out that when a trial court is required to dismiss a health care liability claim under the Medical Liability Insurance Improvement Act (MLIIA) for a claimant’s failure to comply with statutory expert report requirements, the motion to dismiss is treated as in the nature of a motion for sanctions, and a claimant’s non-suit has no effect on the pending motion to dismiss.
See Villafani v. Trejo,
The statute governing certificates of merit, however, is substantially different from the statute governing expert reports.

Tex. Civ. Prac. & Rem.Code Ann. § 150.002(d)-(e) (West 2011),
with id.
§ 74.351(a)-(b) (West 2011). Concerning dismissal of a plaintiffs claims against a defendant design professional for failure to comply with the statutory certificate of merit requirements, chapter 150 does not permit recovery of attorney’s fees, does not provide an independent basis for taxing costs against a plaintiff, and provides for dismissal either without prejudice or with prejudice at the trial court’s discretion; it does not require dismissal with prejudice.
See id.
§ 150.002(d)-(e). Chapter 74 of the MLIIA, on the other hand, requires a trial court to dismiss a health care liability claim with prejudice if the claimant does not comply with the chapter’s statutory expert report requirements, and it mandates an award of costs and attorney’s fees when properly requested and proved.
See id.
§ 74.351(a)-(b);
Trejo,
Because Starwood nonsuited all its claims in the trial court, because CTL’s chapter 150 motion to dismiss is not a motion for sanctions that survives the non-suit, and because this appeal is now moot, *857 we grant Starwood’s emergency motion to dismiss this appeal. We order this interlocutory appeal dismissed as moot.
Notes
. CTL also argues that Starwood has already refiled its claims in another district court and that dominant jurisdiction exists in the 431st Judicial District Court. Starwood’s actions in other trial courts and in other trial court cause numbers, however, are not relevant to whether a justiciable controversy currently exists in this case, whether this appeal is moot, or whether we possess jurisdiction in this interlocutory appeal.
