═══════════════════════════════════════ On Petition for Review from the Court of Appeals for the Third District of Texas ═══════════════════════════════════════

Argued September 9, 2025

JUSTICE SULLIVAN delivered the opinion of the Court, in which Chief Justice Blacklock, Justice Devine, Justice Bland, Justice Huddle, Justice Young, and Justice Hawkins joined.

JUSTICE BUSBY filed a dissenting opinion, in which Justice Lehrmann joined.

The Office of the Attorney General decided that the Texas Commission on Environmental Quality blew a deadline under the Public Information Act back in 2019. Throughout the seven years of litigation that ensued, OAG has disavowed its own decision—and rightly so. “Wisdom too often never comes, and so one ought not to reject it merely because it comes late.” Henslee v. Union Planters Nat’l Bank & Tr. Co., 335 U.S. 595, 600 (1949) (Frankfurter, J., dissenting). We reverse and remand for further proceedings. I On July 1, 2019, TCEQ received a written request from Sierra Club under the Public Information Act. The three-page request sought a broad swath of records relating to a recently issued Development Support Document entitled “Ethylene Oxide Carcinogenic Dose- Response Assessment.” In response, TCEQ sent the following email to Sierra Club on July 2, 2019: We are in receipt of your public information request . . . .

Please clarify whether your request is seeking confidential information. If you request confidential information, we will need to seek an Attorney General opinion for the requested confidential material or information. It may take up to 60 days for the Attorney General to reach a determination on our request.

Please let me know how you would like to proceed.

Within minutes, Sierra Club answered that it “would like to receive all responsive information that TCEQ may believe is confidential, but that must be released under the . . . Public Information Act.” According to TCEQ, many of the requested documents were protected against disclosure by the Public Information Act’s deliberative-process exception. See Tex. Gov’t Code § 552.111; City of Garland v. Dall. Morning News, 22 S.W.3d 351 (Tex. 2000). And so, in a letter to OAG’s Open Records Division dated July 17, 2019, TCEQ “ask[ed] for a decision from the attorney general about whether the

2 information is within that exception,” such that it could withhold the contested documents from Sierra Club. Tex. Gov’t Code § 552.301(a). TCEQ’s letter to OAG was due “not later than the 10th business day after the date of receiving [Sierra Club’s] request.” Id. § 552.301(b). In an opinion of September 23, 2019, OAG decided that TCEQ was two days too late. In counting up business days, OAG excluded the date the public-information request was received (July 1); the Independence Day holiday (July 4); and weekends (July 6, 7, 13, and 14). That calculation put the ten-business-day deadline at July 16, whereas TCEQ’s letter was not actually received by OAG until July 18. A blown deadline meant that “the information requested [was] presumed to be subject to required public disclosure,” and had to be released absent “a compelling reason to withhold the information.” Id. § 552.302. OAG’s opinion went on to decide that the deliberative-process privilege invoked by TCEQ was not sufficiently compelling. As a result, TCEQ faced the prospect of producing over 6,000 pages of documents to Sierra Club. A week later, TCEQ sent OAG a request for correction as to timeliness based on three pieces of information that weren’t in its initial letter. First, TCEQ argued that Friday, July 5 wasn’t a business day because the agency was closed in observance of Independence Day. TCEQ admitted that, “due to a clerical oversight, the referral letter did not include a clear statement informing the OAG that the agency was closed on July 4th and 5th.” Second, TCEQ attached its July 2 emails with Sierra Club and noted that it “could have, but did not choose to rely on [that] clarification, which would have provided the agency an

3 additional day to submit its referral” by resetting the ten-business-day period. Third, TCEQ attached affidavits showing that its initial letter was placed in the interagency mail on July 17, thereby establishing its submission as of that date. OAG declined to reconsider its opinion. TCEQ sued OAG under the Public Information Act for a declaratory judgment allowing it to withhold the contested documents. See id. § 552.324. Sierra Club intervened to seek a writ of mandamus compelling disclosure. See id. § 552.321. OAG conceded, based on the new information in the request for correction, that its own opinion was wrong and that TCEQ had met the ten-business-day deadline. The district court nevertheless granted summary judgment for Sierra Club, ordering TCEQ to produce 6,414 pages of documents. The court of appeals affirmed, holding that TCEQ’s request for an OAG decision was untimely. See 712 S.W.3d 630, 637–40 (Tex. App.— Austin 2022). It rejected the argument, put forth by both TCEQ and OAG, that July 5, 2019, was not a “business day” within the meaning of the Act because TCEQ was closed. Id. at 637–39 (construing Tex. Gov’t Code § 552.301(b)). In addition, the court of appeals held that the ten- business-day clock was not reset by the email exchange on July 2, 2019. Id. at 639–40. Before this Court, OAG (but not Sierra Club) has confessed error in the judgment below. We granted TCEQ’s petition for review.

4 II The parties dispute three issues. First, did TCEQ’s emails with Sierra Club reset the ten-business-day clock? 1 Second, was July 5, 2019 a business day? Third, does TCEQ get the benefit of the “mailbox rule”? We needn’t resolve all three issues. If TCEQ wins on any two, then its letter to OAG was timely. If Sierra Club wins any two, then the letter was untimely. 2 We score the results of this best-of-three series below. 3

1 Sierra Club says TCEQ didn’t preserve this issue. We disagree. TCEQ’s third amended motion for summary judgment used the term “clarification request,” but substantively invoked the narrowing exception. OAG also discussed the narrowing exception in its summary-judgment reply, removing any doubt as to whether the issue was properly before the court. Still, Sierra Club argues that TCEQ didn’t preserve the issue because it wasn’t included in the letter to OAG. But the preservation rules that apply to court proceedings don’t apply to OAG’s. True, the Public Information Act declares that a governmental body may only raise exceptions in court that were “properly raised before the attorney general in connection with its request.” Tex. Gov’t Code § 552.326. But this restriction concerns substantive exceptions to disclosure, not matters of timing. We can therefore assume that timeliness arguments needn’t be preserved before OAG. 2 For the curious, here’s the math: TCEQ’s letter to OAG was due “not later than the 10th business day after the date of receiving [Sierra Club’s] request.” Tex. Gov’t Code § 552.301(b). In an opinion of September 23, 2019, OAG said TCEQ was two days too late. Each of TCEQ’s issues would yield an extra day: (1) July 2 (if that’s when the timer was reset); (2) July 5 (if that wasn’t a “business day”); and (3) July 17 (if that’s when TCEQ’s letter was “received” thanks to the mailbox rule). If TCEQ wins on all three issues, then it actually sent its letter one day early; to win reversal, it just needs two.
