Langer¬†Grogan & Diver has joined a group of lawyers from the American Civil Liberties Union; HIAS Pennsylvania; Villanova University; and¬†Kairys, Rudovsky, Messing & Feinberg to challenge the Executive Order of President Trump blocking individuals from seven Muslim-majority countries from entering the United States. On Tuesday, in a front-page article, Lizzy McLellan of the Legal Intelligencer detailed the lawyers’ weekend mobilization efforts at the Philadelphia airport and at law offices across the city.

Mobilization began soon after President Trump signed the Executive Order. According to Langer Grogan & Diver partner John Grogan, the speed with which the lawyers were able to mobilize was because the group had worked together previously on immigration and refugee-related issues. “It’s so important to have these networks in place,” said Grogan, who along with Howard Langer, Ned Diver, Irv Ackelsberg, and Peter Leckman assisted in drafting court papers and other related issues.

Ultimately, the efforts of Grogan and his partners were successful. All travelers who had been detained were released and the U.S. Attorney’s Office in Philadelphia assured the team that no further travelers would be detained pursuant to President Trump’s Executive Order.

Nevertheless, the lawyers at Langer Grogan & Diver are prepared for additional legal battles. “I do expect that our services are going to be in much greater demand in the coming months. We’ll make the sacrifices we have to make in terms of our own work load to make sure we’re playing a role,” Grogan said.
