DEAHL, Associate Judge: Mark Jacobson filed a defamation suit after a scientific journal published an article criticizing a research paper of his. Jacobson

sued the article’s lead author, Christopher Clack, and the National Academy of Sciences (“NAS”), which publishes the journal. Jacobson sought more than $10 million in damages from each of them. Clack and NAS filed special motions to dismiss under the District of Columbia Anti-Strategic Lawsuits Against Public Participation Act, or Anti-SLAPP Act, D.C. Code §§ 16-5501–5505. The trial court held a hearing on the motions and hinted that it was likely to grant them. Two days later, before the trial court ruled, Jacobson voluntarily dismissed his suit.

Clack and NAS moved for attorneys’ fees under the Anti-SLAPP Act’s fee-

shifting provision, which allows a court to award attorneys’ fees to a defendant who “prevails in whole or in part” in their special motions to dismiss. D.C. Code § 16-5504(a). The court granted the motion for attorneys’ fees, awarding $428,723 to NAS and $75,000 to Clack. Jacobson now appeals that award and argues that his voluntary dismissal of his suit means that Clack and NAS did not “prevail” as is required before attorneys’ fees can be awarded. That raises a question of first impression for this court: whether and when a party can be said to have prevailed in a special motion to dismiss that is followed by a voluntary dismissal of the suit. We agree with the trial court that NAS and Clack prevailed in their motions to dismiss and therefore were appropriately awarded attorneys’ fees, and so we affirm.

I.

Mark Jacobson is a professor at Stanford University. In 2015, he was the lead author on a paper published in The Proceedings of the National Academy of Sciences (“PNAS”), which concluded that the U.S. power grid could inexpensively move to “100% wind, water, and solar” energy sources by 2050 without the need for “natural gas, biofuels, nuclear power, or stationary batteries.” PNAS gave Jacobson and his research team one of its annual awards for making an “outstanding contribution” to the field of applied environmental sciences.

Christopher Clack co-authored an article in 2017, also published in PNAS, that was very critical of Jacobson’s methodologies and conclusions. Clack’s paper posited that Jacobson’s study “used invalid modeling tools, contained modeling errors, and made implausible and inadequately supported assumptions.” Clack and his co-authors provided detailed calculations and reasons for questioning Jacobson’s conclusions, which they said “are not supported by adequate and realistic analysis and do not provide a reliable guide to whether and at what cost such a transition might be achieved.” The article continued: “[T]he weight of the evidence suggests that a broad portfolio of energy options will help facilitate an affordable transition to a near-zero emission energy system.”

Before publishing Clack’s critique, PNAS sent the article to Jacobson for comment, and his responses were forwarded to Clack and his co-authors, who made some minor revisions. PNAS also allowed Jacobson and his co-authors to write a rebuttal to Clack’s article, to be published alongside it. Jacobson did not think that was sufficient and instead insisted that Clack’s article be shelved entirely. He informed a PNAS editor over email that he had retained an attorney who would send a cease-and-desist letter, and he threatened to seek a preliminary injunction to prevent publication of Clack’s critique. PNAS nonetheless printed both Clack’s article and Jacobson’s rebuttal in the same issue and posted them online simultaneously. In his rebuttal piece, Jacobson asserted that it was Clack’s analysis, not his, that was “riddled with errors” and contained “demonstrably false” claims.

Jacobson sued Clack and NAS in D.C. Superior Court. 1 He alleged that Clack’s article consisted of “egregious falsehoods and misstatements” that injured his reputation. Jacobson asserted claims of defamation against both Clack and NAS, and additional promissory estoppel and breach-of-contract claims against NAS on the theory that the journal violated its editorial policies by publishing Clack’s article. He sought damages “believed to be in excess of” $10 million each from Clack and

NAS, punitive damages, and a retraction of Clack’s article. Two weeks after filing the lawsuit, Jacobson submitted to PNAS “errata,” responsive to some of the points raised in Clack’s article, to “clarify our hydropower assumption because the original text describing this assumption was not clear.” NAS and Clack each filed special motions to dismiss under the District’s Anti-SLAPP Act. D.C. Code § 16-5502. Jacobson opposed the motions and, separately, sought targeted discovery. The trial court denied Jacobson’s discovery request and held a hearing on the special motions to dismiss.

At the hearing, the trial judge expressed serious skepticism about Jacobson’s chances of success on the merits. In questioning Jacobson’s counsel, she said that “criticizing ideas is not defamation” and “[w]hether it offends you is not the standard.” The judge distinguished between assertions of inaccuracies and assertions of misconduct—the former being fodder for scientific disagreement and the latter potentially actionable as defamation. She noted that Clack’s article never claimed that Jacobson “falsified data, [] engaged in misconduct, [or] deliberately misled the public.” The judge seemed to agree with NAS and Clack that this was a paradigmatic scientific disagreement—not one to be hashed out and resolved in court. She suggested at one point that, if anything, it was Jacobson’s characterizations of Clack’s article, rather than vice versa, that might “be capable of

defamatory interpretation.” She told the parties that she would issue a written decision “promptly” and adjourned.
