Supreme Court Interprets Dodd-Frank 
Whistleblower Protections: Implications for 
Securities Law and Beyond  
March 8, 2018 
On February 21, 2018, the Supreme Court decided in Digital Realty Trust, Inc. v. Somers that the anti-
retaliation protections in the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 
(Dodd-Frank) apply only to whistleblowers who report suspected securities law violations to the 
Securities and Exchange Commission (SEC or Commission). In so doing, the Court rejected a more 
expansive reading of Dodd-Frank that would have extended its whistleblower protections to those who 
report securities violations internally within their organization and suffer retaliation, even if they did not 
take the additional step of reporting to the SEC. The ruling not only has potentially important implications 
for the nature and quantity of potential whistleblower actions brought under federal securities law, but 
Digital Realty also provides broader insights into the Supreme Court’s current approach toward statutory 
interpretation. 
The details of the Digital Realty case and the circuit court split leading up to the Court’s review are 
discussed in a prior Sidebar. In short, the respondent Somers argued that Dodd-Frank whistleblower 
protections applied to his reports of suspected securities law violations to upper management at Digital 
Realty, even though he only reported internally and not to the SEC. While the Sarbanes-Oxley Act of 
2002 (SOX) already affords employees certain anti-retaliation protections for internal reporting, Dodd-
Frank provides more generous protections for “whistleblowers,” including the ability to file suit directly 
in federal district court without first exhausting an administrative process, a longer statute of limitations, 
and recovery of double back-pay with interest. Digital Realty hinged on whether Dodd-Frank protects a 
narrower class of individuals than SOX based on Dodd-Frank’s definition of the term “whistleblower.” 
The relevant section of Dodd-Frank defines a “whistleblower” as “any individual who provides . . . 
information relating to a violation of the securities laws to the Commission.” However, setting up the 
parties’ dispute, Dodd-Frank’s anti-retaliation provision also prohibits an employer from discriminating 
against a “whistleblower” who, among other things, makes “disclosures that are required or protected 
under” SOX. Because SOX, in turn, protects internal reporting, Somers argued that the Dodd-Frank 
provision encompassed internal reporters as well.

The Supreme Court unanimously held that the definition of “whistleblower” provided “an unequivocal 
answer” that resolved the case, affirming the principle that “[w]hen a statute includes an explicit 
definition, we must follow that definition.” The Court distinguished the case from prior instances in 
which it did not hold a statutory definition to control because, unlike those cases, the results here would 
not be incongruous with Congress’s regulatory scheme. Namely, the Court emphasized several times 
throughout its opinion that the purpose of the enhanced whistleblower provision was “to motivate people 
who know of securities law violations to tell the SEC,” quoting a Senate Report regarding Dodd-Frank. 
Moreover, the Court rejected Somers’s arguments that requiring reporting to the SEC to qualify as a 
“whistleblower” would lead to results incompatible with Congress’s intent. For example, the Court 
reasoned that the Dodd-Frank anti-retaliation provision’s reference to SOX would still be meaningful 
under the narrower definition because it would protect those who report both internally and to the SEC, 
but incur retaliation for the internal report. The Court observed that such a scenario may in fact be 
commonplace because, as data from the SEC presented to the Court showed, approximately 80% of those 
receiving SEC whistleblower awards in 2016 had indeed reported internally before making their 
complaints to the SEC.   
The ultimate impact of Digital Realty’s more narrow scope for Dodd-Frank’s whistleblower provisions is 
unclear. In supporting the petitioner’s arguments in Digital Realty, notable amici like the U.S. Chamber of 
Commerce favored the narrower whistleblower definition because, in their view, an expansive definition 
encompassing internal reporters would have allowed for a greater quantity of costly whistleblower suits to 
be filed against companies in federal court, while spurning internal and administrative processes set up by 
SOX. However, commentators have also noted that the Court’s ruling may have the practical effect of 
incentivizing whistleblowers to report complaints directly to the SEC instead of attempting resolutions to 
complaints internally, potentially leading to increased regulatory action and greater costs for companies. 
Digital Realty also provides several statutory interpretation takeaways. In addition to affirming the 
importance of a statute’s definitions section, as noted above, the Digital Realty decision also presented an 
opportunity for the Supreme Court to revisit—and differ on—the propriety of considering legislative 
history when interpreting statutory language. While concurring that the “whistleblower” definition 
controlled the outcome of the case, Justice Thomas, joined by Justices Alito and Gorsuch, wrote 
separately regarding their disagreement with the Court opinion’s reliance on the Senate Report in 
interpreting the definition of whistleblower. Rather, they “join[ed] the Court’s opinion only to the extent it 
relies on the text of Dodd-Frank,” elaborating that the language of a statute enacted by Congress should 
ultimately control, rather than potentially unreliable documents explaining congressional intent. Justice 
Sotomayor, on the other hand, authored another concurring opinion, joined by Justice Breyer, in which 
she stressed that it is appropriate to look to legislative history as an interpretive aid, “even when, as here, 
a statute’s meaning can clearly be discerned from its text,” in order to confirm and enhance the Court’s 
understanding of the language. In these respects, the Digital Realty case has potentially broad import for 
Congress in considering how courts may view statutory definitions and legislative history.
