 On April 21, 2014, the Supreme Court granted Lewin's certiorari petition in the follow-up case of "Zivotofsky v. Kerry", which concerns the question whether a federal statute that directs the Secretary of State, on request, to record the birthplace of an American citizen born in Jerusalem as born in "Israel" on a Consular Report of Birth Abroad and on a United States passport is unconstitutional on the ground that the statute "impermissibly infringes on the President's exercise of the recognition power reposing exclusively in him".Lewin has been a champion in advocating for First Amendment rights and civil liberties.He has successfully argued many cases involving the right to display the Chanukah menorah in a public forum, including two such cases before "en banc" courts of the Sixth and Eleventh Circuits.
