OPINION In a medical-negligence case, defendant physician Oluwatosin L. Ajao moved unsuccessfully to dismiss plaintiff Allison Turner Hall’s claims on the ground that Hall failed to serve Ajao with an expert report before the statutory deadline. Although the trial court had granted Hall’s motion to modify the deadline pursuant to certain of the Supreme Court of Texas’s Emergency Orders Regarding the COVID-19 State of Disaster, Ajao brings two issues on interlocutory appeal arguing that the trial court abused its discretion in granting the motion to modify the deadline—and thus, in denying Ajao’s motion to dismiss—because Hall failed to show that a “disaster-caused delay” necessitated the extension. We overrule the issues presented, modify the order denying the motion to dismiss to reflect that it was signed on February 8, 2021, rather than February 8, 2020, and with this modification, we affirm the challenged orders. I. A claimant asserting a health care liability claim against a physician ordinarily must serve on the physician an expert report not later than the 120th day after the physician files an original answer. See TEX. CIV. PRAC. & REM. CODE § 74.351(a). The expert report is to provide a fair summary of the expert’s opinion regarding the applicable standards of care, the manner in which the care rendered by the defendant physician failed to meet the standards, and the causal relationship between that failure and the injury, harm, or damages claimed. See id. § 74.351(r)(6). If the claimant fails to serve the defendant physician with an expert report within the allotted time, the trial court must, on the defendant’s motion, dismiss the claim against the physician with prejudice and award the physician her reasonable attorney’s fees and costs of court. See id. § 74.351(b). These deadlines ordinarily would govern Hall’s medical-negligence claims against Ajao. Ajao filed her original answer on December 9, 2019, so under the statute, the 120-day deadline for Hall to serve Ajao with an expert report fell on April 7, 2020. That date, however, did not fall within ordinary times. On March 13, 2020, Governor Abbott declared a state of disaster throughout Texas due to the “imminent threat” posed by the novel coronavirus COVID-19.[1] That same day, the Supreme Court of Texas issued the First Emergency Order Regarding the COVID-19 State of Disaster (hereinafter, First Emergency Order). Paragraph 2(a) of the First Emergency Order provided as follows: Subject only to constitutional limitations, all courts in Texas may in any case, civil or criminal—and must to avoid risk to court staff, parties, attorneys, jurors, and the public—without a participant’s consent . . . [m]odify or suspend any and all deadlines and procedures, whether prescribed by statute, rule, or order, for a stated period ending no later than 30 days after the Governor’s state of disaster has been lifted . . . .[2] With amendments inapplicable here, this language was carried forward in the Twelfth Emergency Order,[3] which renewed the First Emergency Order. The Seventeenth Emergency Order renewed and amended the pertinent parts of the Twelfth Emergency Order as follows: Subject only to constitutional limitations, all courts in Texas may in any case, civil or criminal—and must to avoid risk to court staff, parties, attorneys, jurors, and the public—without a participant’s consent . . . modify or suspend any and all deadlines and procedures, whether prescribed by statute, rule, or order, for a stated period ending no later than September 30, 2020 . . . .[4] Subsequent emergency orders pushed the extension deadline back to later dates, ultimately allowing a district court in a case such as this to modify case deadlines to expire as late as October 1, 2021.[5] II. Before the statutory deadline, Hall moved for an extension pursuant to the Emergency Orders. She filed a first amended motion before serving the expert report on September 4, 2020. In response, Ajao objected to the requested extension on the ground that Hall had “failed to provide any evidentiary support showing that the risk of COVID-19 is the reason for the delay.” Ajao then moved to dismiss Hall’s claims on the ground that Hall had not served the expert report within 120 days of Ajao’s original answer. Hall responded to the motion to dismiss and filed a second amended to motion to modify the expert-report deadline. To both, Hall attached the unsworn declaration of her attorney Charles D. Marshall. Marshall stated that before the statutory deadline, he contacted three physicians as potential expert witnesses to author the expert report. One of the physicians was unable to assist for unstated reasons, and two stated that they were unavailable due to circumstances related to the COVID-19 pandemic. Marshall further declared that he contacted two physicians in June 2020, both of whom were unavailable at that time for unstated reasons. One of those two physicians later became available and wrote the expert report served on Ajao on September 4, 2020. The trial court denied Ajao’s motion to dismiss on February 8, 2021.[6] A few weeks later, the trial court signed an order on March 4, 2021, extending the expert- report deadline to and including September 4, 2020, that is, the date Hall actually served the expert report. III. On appeal, Ajao argues that the trial court was required to grant her motion to dismiss because Hall failed to serve the expert report before the expiration of the statutory deadline. Although Hall served the report within the deadline as modified by the trial court, Ajao maintains that the trial court erred in extending the deadline, and thus, the statutory deadline applies. Ajao’s arguments require us to review the trial court’s ruling on the motion to dismiss. We review the denial of a motion to dismiss a health care liability claim for abuse of discretion. See Jelinek v. Casas, 328 S.W.3d 526, 539 (Tex. 2010). The court abuses its discretion if it acts arbitrarily or unreasonably, without reference to any guiding rules or principles. Downer v. Aquamarine Operators, Inc., 701 S.W.2d 238, 241–42 (Tex. 1985). Because the denial of Ajao’s motion to dismiss is based on the trial court’s extension of the expert-report deadline, our review necessarily encompasses that ruling as well.[7] The same abuse-of-discretion standard applies to our review of a trial court’s decision to extend case deadlines under the Emergency Orders. See, e.g., Neurological Assocs. of San Antonio, P.A. v. Torres, No. 04-21-00120-CV, 2022 WL 1559101, at *2 (Tex. App.—San Antonio May 18, 2022, no pet. h.) (mem. op.); Floeck v. Crescent Continuing Care Ctr. Co., No. 14-21-00101-CV, 2022 WL 1463767, at *4 (Tex. App.—Houston [14th Dist.] May 10, 2022, no pet. h.) (mem. op.). Our review of the trial court’s extension of the expert-report deadline also requires us to construe the applicable provisions of the Emergency Orders. The construction and effect of a court order are questions of law, which we determine de novo based on the order’s plain language. Clay Expl., Inc. v. Santa Rosa Operating, LLC, 442 S.W.3d 795, 798 (Tex. App.—Houston [14th Dist.] 2014, no pet.). IV. Ajao argues that to obtain a deadline extension under the Emergency Orders, a party “must present evidence of the disaster’s impact on the party’s ability to meet a deadline,” that is, that there is a “disaster-caused delay” in a party’s ability to meet the deadline. In support of this position, Ajao cites cases in which a medical- negligence claimant argued that a time period should have been extended in the aftermath of Hurricane Harvey or Hurricane Rita. See Franklin v. Longview Med. Ctr., L.P., No. 12-18-00198-CV, 2019 WL 2459020, at *3–4 (Tex. App.—Tyler June 5, 2019, pet. denied) (mem. op.) (Hurricane Harvey); Pollard v. Walgreen, Co., No. 09-06-447-CV, 2007 WL 2493489, at *1–2 (Tex. App.—Beaumont Sept. 6, 2007, pet. denied) (mem. op.) (Hurricane Rita). The identical argument relying on these same two cases was rejected by our sister court, noting that the emergency orders issued by the Supreme Court of Texas after Hurricanes Harvey and Rita “are notably different” from the terms of the Emergency Orders concerning the COVID- 19 pandemic. See Kim v. Ramos, 632 S.W.3d 258, 270–71 (Tex. App.—Houston [1st Dist.] 2021, no pet.). The Franklin case dealt with an emergency order in response to Hurricane Harvey, and that order provided that “all courts in Texas should consider disaster- caused delays as good cause for modifying or suspending all deadlines and procedures.” Franklin, 2019 WL 2459020, at *3–4.[8] Although Ajao argues that the same standard applies in this case, the Emergency Orders at issue here contain no such language. In Pollard, the claimant argued that “the trial court abused its discretion by not enlarging the time for filing the expert report following Hurricane Rita.” Pollard, 2007 WL 2493489, at *1. Although the Pollard court stated there was no evidence “that the hurricane-related displacement of the attorney or the pharmacist who provided the expert report was the reason for the delay,”[9] the court identified no authority that would have allowed an extension of the expert-report deadline if such evidence had been presented. Even if the Pollard court had relied on the emergency order issued by the Texas Supreme Court in the wake of Hurricane Rita, that order contained different language from the Emergency Orders relating to the COVID-19 pandemic. See Kim, 632 S.W.3d at 271.[10] We agree with the First Court of Appeals’ holding that we must construe the COVID-19 Emergency Orders according to their plain terms, and those terms authorize a trial court to modify an expert-report deadline “[s]ubject only to constitutional limitations.”[11] The Emergency Orders do not condition a deadline extension on evidence that COVID-19 affected the claimant’s ability to meet the initial expert-report deadline. V. Ajao additionally argues that Hall did not timely move for modification of the expert-report deadline. Ajao does not dispute that Hall filed her initial motion before the expert report was due; rather Ajao points out that Hall did not set a hearing for her original or first amended motion to modify the deadline. Ajao also asserts that Hall assumed in each her original and first amended motions that deadline extensions were automatic, and that she did not seek relief from the court. These arguments do not affect our analysis because Hall filed—and the trial court heard and granted—a second amended motion to modify the deadline. An amended motion supersedes and supplants the preceding motion. See W. C. Turnbow Petroleum Corp. v. Fulton, 145 Tex. 56, 64, 194 S.W.2d 256, 259 (1946); Williams v. Bayview-Realty Assocs., 420 S.W.3d 358, 364 (Tex. App.—Houston [14th Dist.] 2014, no pet.). An amended motion also relates back to the date of the original motion. See, e.g., Clewis v. Safeco Ins. Co. of Am., No. 2-08-184-CV, 2009 WL 2414377, at *4 (Tex. App.—Fort Worth Aug. 6, 2009, no pet.) (mem. op.); Ex parte Bregenzer, 802 S.W.2d 884, 886 (Tex. App.—Houston [1st Dist.] Jan. 17, 1991, orig. proceeding). Thus, Hall’s second amended motion to modify the expert-report deadline replaced her original motion and is considered filed as of April 3, 2020— before the expert report was due.[12] VI. We conclude that the trial court did not abuse its discretion in granting Hall’s motion to extend the expert-report deadline or in denying Ajao’s motion to dismiss. There is, however, a scrivener’s error in the date of the ruling denying the motion to dismiss. We accordingly modify the date of the order denying the motion to dismiss to reflect that it was signed on February 8, 2021, rather than on February 8, 2020. We overrule the issues presented affirm the challenged orders as modified. /s/ Tracy Christopher Chief Justice Panel consists of Chief Justice Christopher and Justices Bourliot and Spain (Spain, J., dissenting).
