Opinion of the Court
A
The HEROES Act authorizes the Secretary to “waive or modify any statutory or regulatory provision applicable to the student financial assistance programs under title IV of the [Education Act] as the Secretary deems necessary in connection with a war or other military operation or national emergency.” 20 U. S. C. §1098bb(a)(1). That power has limits. To begin with, statutory permission to “modify” does not authorize “basic and fundamental changes in the scheme” designed by Congress. MCI Telecommunications Corp. v. American Telephone & Telegraph Co., 512 U. S. 218, 225 (1994). Instead, that term carries “a connotation of increment or limitation,” and must be read to mean “to change moderately or in minor fashion.” Ibid. That is how the word is ordinarily used. See, e.g., Webster’s Third New International Dictionary 1952 (2002) (defining “modify” as “to make more temperate and less extreme,” “to limit or restrict the meaning of,” or “to make minor changes in the form or structure of [or] alter without transforming”). The legal definition is no different. Black’s Law Dictionary 1203 (11th ed. 2019) (giving the first definition of “modify” as “[t]o make somewhat different; to make small changes to,” and the second as “[t]o make more moderate or less sweeping”). The authority to “modify” statutes and regulations allows the Secretary to make modest adjustments and additions to existing provisions, not transform them.
The Secretary’s previous invocations of the HEROES Act illustrate this point. Prior to the COVID–19 pandemic, “modifications” issued under the Act implemented only minor changes, most of which were procedural. Examples include reducing the number of tax forms borrowers are required to file, extending time periods in which borrowers must take certain actions, and allowing oral rather than written authorizations. See 68 Fed. Reg. 69314–69316.
Here, the Secretary purported to “modif[y] the provisions of” two statutory sections and three related regulations
