Peter Karanjia

Co-chair, Appellate Practice
Peter Karanjia is co-chair of Davis Wright Tremaine’s appellate practice group and a member of the firm's communications, media, IP & technology group and its privacy & security group. Peter has extensive experience in appellate and regulatory litigation (having litigated over 100 appeals), government investigations, and complex civil litigation. For each of the past three years (2015, 2016, and 2017), Law360 selected Peter as an "MVP of the Year" for his "successes in high-stakes litigation." He is also recommended by Chambers USA (2017) as an experienced litigator and appellate lawyer, and is regularly quoted in the media on cyberlaw, new technology, and privacy law.

Peter rejoined the firm in 2013 after serving for three years as deputy general counsel of the Federal Communications Commission, where he was responsible for overseeing all of the agency’s litigation. At the FCC, Peter argued a number of precedent-setting appeals, including one—described by The New York Times as a "big win" for the Commission—involving novel issues concerning mobile Internet services on smartphones and tablets. Previously, Peter served as a senior member of the Office of New York Attorney General Andrew M. Cuomo, where he was responsible for appellate litigation and other special projects. As Special Counsel to the Solicitor General of New York (from 2007 to 2010), Peter successfully briefed and argued several major appeals, including a constitutional challenge to a first-of-its-kind statute governing online commerce. As The Washington Post reported, the "multibillion-dollar issue" at stake in the case "is one of the most important in modern retailing."

Hernández v. Mesa

Filed amicus brief on behalf of former police chiefs supporting petitioners in case involving the extraterritorial application of the Constitution and issues of qualified immunity arising out of the fatal shooting of a Mexican teenager at the U.S.-Mexico border. The brief argued that the court of appeals erred in granting qualified immunity to the federal agent, and the Supreme Court agreed. 137. S. Ct. 2003 (2017)

T-Mobile v. City of Roswell, Georgia

Successfully sought cert. and obtained reversal of 11th Circuit decision in litigation challenging municipality’s denial of a wireless provider’s application to install a wireless facility. S Ct., 2015 WL 159278 (Jan. 14, 2015)

Lanell Williams-Yulee v. The Florida Bar

Filed amicus brief on behalf of the American Civil Liberties Union in a First Amendment litigation challenging state restrictions on solicitation of campaign contributions by judicial candidates. 135 S. Ct. 1656 (2015)

City of Arlington, Texas v. FCC*

Writing for Bloomberg, Professor Cass Sunstein has described the case as "an important victory" for the Government "that will long define the relationship between federal agencies and federal courts." 113 S. Ct. 1863 (2013)

FCC v. Fox Television Stations*

Defended against broad First Amendment and due process challenges to FCC rulings applying the agency’s broadcast indecency policy.

Ct. 2307 (2012)

FCC v. AT&T*

Successfully defended an FCC order in a Freedom of Information Act case. Reversing an adverse court of appeals decision, the Supreme Court agreed with the FCC that corporations may not assert “personal privacy” interests under an exemption from the Act’s disclosure requirement. 131 S. Ct. 1177 (2011)

Talk America v. Michigan Bell Tel. Co.*

Successfully urged the Supreme Court to defer to the FCC’s understanding of an agency rule regarding the prices that incumbent telephone companies can charge competitors for certain transmission facilities.

Ct. 2254 (2011)

Tribune Co., et al. v. FCC*

Successfully resisted petitions for certiorari filed by media companies seeking review of a 3rd Circuit decision that rejected First Amendment and statutory challenges to the FCC’s most recent media ownership rules. 133 S. Ct. 64 (2012); 133 S. Ct. 73 (2012); 545 U.S. 1123 (2012)

Ameren Corp. v. FCC

On behalf of the National Cable & Telecommunications Association, successfully briefed and argued appeal as intervenor in support of a 2015 FCC order that limits the rents communications providers must pay to electric utilities in order to use their facilities to provide broadband service.  The FCC anticipated that its order would incentivize broadband deployment by saving Internet Service Providers $150-200 million per year. 865 F.3d 1009 (8th Cir. 2017), pet. for cert. docketed, No. 17-819 (Sup. Ct. Dec. 7, 2017)

Filed amicus brief in the D.C. Court of Appeals on behalf of eight technology companies (Apple, Avvo, Dropbox, Google, Microsoft, Snap, Twitter, and Yelp) and The Reporters Committee for Freedom of the Press in support of Facebook’s First Amendment challenge to a gag order concerning warrants the company received under the Stored Communications Act. The search warrants were issued in connection with a criminal investigation into incidents arising out of the January 20, 2017 presidential inauguration. Following briefing, the government voluntarily dismissed its appeal. 2017 WL 5502809 (D.C. Super. Ct. Crim. Div. Nov. 9, 2017)

Cir. 2017)

FCC cybersecurity enforcement action

Represented telecommunications providers in the first ever FCC enforcement proceeding involving cybersecurity. Case arose out of an alleged data breach involving disclosure of proprietary customer information online. As Bloomberg BNA reported, the case not only marked the FCC’s “ent[ry] [into] the data security enforcement filed,” it was also (at the time) “the largest privacy action in the FCC’s history.” In 2015, the case settled on favorable terms for a fraction of the fine proposed by the FCC. (2015)

Matter of a warrant to search a certain email account controlled and maintained by Microsoft Corporation

Represented Amazon and Accenture as amici curiae before the Second Circuit in a closely-watched case involving whether the government may issue search warrants under the federal Stored Communications Act (SCA) to require providers of cloud computing services to turn over emails and other electronic documents stored in datacenters overseas—here, emails stored by Microsoft on a server in Dublin, Ireland. Consistent with the position of our amicus brief, the Second Circuit held that SCA search warrants cannot be applied outside the United States.  The New York Times described this as a “surprise victory” in a case with significant “privacy implications for the growing cloud computing business, with implications for internet email and online storage, among other services.” 829 F.3d 197 (2d Cir. 2016), cert. granted (Sup. Ct. No. 17-2). (Ongoing)

FTC v. T-Mobile

Represented T-Mobile in the first ever litigation brought by the Federal Trade Commission against a telecommunications carrier under Section 5 of the FTC Act. The FTC alleged that the carrier engaged in deceptive and unfair practices by charging customers for unauthorized premium text message (SMS) services provided by third parties.  As PC Magazine reported, this was “the second-largest mobile cramming settlement ever handed down.”  Angela Moscaritolo, ‘T-Mobile Settles Phone-Cramming Case for $90 Million,’ PCMag, Dec. 19, 2014. It is also one of a handful of settlements ever negotiated that involved the FTC, the FCC, and the Attorneys General from all 50 States and the District of Columbia.

New Cingular Wireless PCS, et al. v. Picker, et al.

Represented Comcast in a successful joint effort by a coalition of telecommunications providers to block a ruling by an Administrative Law Judge of the California Public Utilities Commission, ordering the providers to share their highly sensitive business data with third parties.  The U.S. District Court for the Northern District of California granted plaintiffs a preliminary injunction, preventing disclosure of the data, and the Commission subsequently terminated its proceeding.

Comcast of Oregon v. City of Eugene

Briefed and argued before the Supreme Court of Oregon a case of first impression under the Internet Tax Freedom Act. 359 Or. 528 (2016).

Twitter v. Holder

(Ongoing)

Cellco Partnership v. FCC*

Successfully briefed and argued before the D.C. Circuit an appeal challenging the FCC’s "data roaming" rule, which enables users of smartphones and other mobile devices to obtain nationwide mobile Internet access. 700 F.3d 534 (D.C. Cir. 2012)

Verizon v. FCC*

Responsible for litigation strategy, including overseeing briefing and extensive coordination with amici and a coalition of technology company intervenors (including Amazon, eBay, Facebook, Google, Netflix, and Skype), in litigation before the D.C. Circuit challenging the FCC’s 2010 order adopting “Open Internet” or “net neutrality” rules. While vacating two of the three rules, the D.C. Circuit upheld the agency’s assertion of jurisdiction to regulate Internet-related services. As CNET reported, "[t]his part of the decision is an important victory for the FCC." 740 F.3d 623 (D.C. Cir. 2014)

Time Warner Cable, et al. v. FCC*

Successfully briefed and argued a First Amendment case challenging the facial constitutionality of the FCC’s “program carriage” rules, which prohibit cable companies and other programing distributors from rejecting programming by independent networks based on their unaffiliated status. The 2nd Circuit vacated a provision of the rules authorizing certain interim relief for failure to follow required notice-and-comment procedures, but ruled that the agency could readopt its rule consistent with the Act.  729 F.3d 137 (2d Cir. Sept. 4, 2013), LLC and v. New York State Department of Taxation & Finance*

Successfully briefed and argued on behalf of the State of New York related appeals in which Internet retailers challenged the constitutionality of a New York statute governing the tax-collection obligations of out-of-state Internet retailers—the first statute of its kind. The New York appellate court rejected facial challenges under the Commerce Clause and Due Process Clause, while describing the case as having “far-reaching ramifications because of the exponential expansion of cyberspace in general, and commerce over the Internet in particular.” 81 A.D.3d 183 (N.Y. App. Div. 1st Dep’t 2010) aff’d, 987 N.E.2d 621 (2013), cert. denied, S. Ct., 2013 WL 4522065 (Dec. 2, 2013)

TCPA class action litigations*

In response to requests from various appellate courts in class action litigations under the Telephone Consumer Protection Act, filed amicus briefs on behalf of the FCC setting forth the agency’s authoritative interpretations of the TCPA. In seeking rehearing as a non-party intervenor in another case, also persuaded the 6th Circuit to amend its opinion allowing a class action plaintiff to collaterally attack an FCC rule exempting certain telemarketing calls from liability under the TCPA; in its amended opinion, the court of appeals agreed with the FCC that the district court lacked jurisdiction to consider the plaintiff’s arguments attacking the agency’s rule.

Intellectual Property

Eight Mile Style, LLC v. Apple Computer, Inc., et al.

Represented Viacom and MTV Networks in a case brought by Eminem’s music publishing company alleging copyright infringement, false endorsement under the Lanham Act, and unfair competition arising out of use of an Eminem song in a commercial for Apple’s iPod. Case settled.

Ct. N.Y. County June 29, 2010)
