In Airbnb Inc.’s new lawsuit against the New York City government over its law requiring disclosure of hosts offering up rooms for rent in the city, the company has once again enlisted the legal firepower of Roberta Kaplan, a star litigator well-known for her civil rights work.

Kaplan, who successfully argued before the U.S. Supreme Court in 2013 to strike down the Defense of Marriage Act, the federal law that effectively banned same-sex marriage, is teaming up with Sharon Nelles of Sullivan & Cromwell, arguing that the city’s new law is an “extraordinary” act of government overreach that was the product of a multimillion-dollar campaign by the hotel industry and was designed to frighten New Yorkers into giving up home sharing.
