Fеderal Rule of Civil Procedure 5.1 requires a party contesting the constitutionality of a federal statute to serve the Attorney General of the United States with notice of the action. 28 U.S.C. § 2403(a) requires the court ruling on such a challenge to do the same. Upon receiving notice, the Attorney General has a right to intervene as a party in the case and present evidence if he so desires. Id.
In this case, in response to an enforcement action brought by the Attorney Gеneral of Oklahoma, defendant-appellant Tim Pope challenged the constitutionality of a portion of the Telephone Consumer Protection Act (“TCPA”), 47 U.S.C. § 227, which regulates the use of automated telephone dialing systems. He argues that requiring identification of the party responsible for the automated phone call violates his free speech rights under the First Amendmеnt because it forces him to forgo his ability to speak anonymously. 1 Neither Mr. Pope nor the district court notified the United States Attorney General of this constitutional challenge to a federal statute. At oral argument, neither party even seemed aware that this requirement existed. 2 We therefore vacate the district *1216 court’s judgment and remand to the district court to certify the case to the Attorney General pursuаnt to Federal Rule of Civil Procedure 5.1 and 28 U.S.C. § 2403.
The certification requirement protects the public interest by ensuring that the Executive Branch can make its views on the constitutionality of federаl statutes heard. 28 U.S.C. § 2403(a); 7C Charles Alan Wright, Arthur R. Miller & Mary Kay Kane, Federal Practice and Procedure § 1915 (2d еd.1986); Note,
Federal Intervention in Private Actions Involving the Public Interest,
65 Harv. L.Rev. 319, 321-324 (1951);
see also Tonya K. ex rel. Diane K. v. Bd. of Educ. of Chi.,
When the parties and the court statutorily charged with notifying the Attorney General of a constitutional challenge to a federal statute fail to do so, the appellate court has discretion to respond in different ways, depending on the nature of the arguments and the progress of the litigation.
See, e.g., In re Young,
In this case, however, we find it appropriate to remand to the district court. A number of arguments were waived or abandoned by the parties either in district court or on appeаl, including the appropriate standard of review,
cf. McIntyre v. Ohio Elections Comm’n,
The publiс interest is not well served when a federal statute is challenged and potentially invalidated in litigаtion among private parties, or even in litigation involving state governments, in the absence of input from the institution that has the responsibility and expertise to defend Acts of Congress. We therefоre vacate the judgment and remand to the district court with instructions to notify the Attorney General оf the United States of this constitutional challenge. If the Attorney General chooses to intervene, he may present new arguments and issues and present new evidence, without limitation based on law of the case or other preclusion doctrines. If the Attorney General choosеs not to intervene, the district court should reinstate its former opinion. In that event, should there be an appeal, this Court will rule on the basis of the previously submitted briefs and argument.
We VACATE the district court’s order and REMAND to the district court for further proceedings in accordance with this opinion.
Notes
. 47 U.S.C. § 227(d)(3)(A) authorizes and requires the Federal Communications
Commission to adopt a regulation mandating that:
all artificial or prerecorded teleрhone messages (i) shall, at the beginning of the message, state clearly the identity of the business, individual, оr other entity initiating the call, and (ii) shall, during or after the message, state clearly the telephоne number or address of such business, other entity, or other individual....
The regulations were adopted in 47 C.F.R. § 64.1200(b).
. At oral argument, counsel informed the Cоurt that the state had provided notice to the Federal Communications Commission that it was bringing an enforcement action under the TCPA, pursuant to 47 U.S.C. § 227(f)(1). This requirement, however, is in addition to the general certification rule, which requires that the United States Attorney General receive notice when the constitutionality of the statute is being challenged.
