The First Liberty Institute worked in partnership with the Institute for Justice to challenge the exclusion of religious options from Maine’s school choice program. At present, parents cannot use high school tuition payments offered by local school districts at qualified religious schools due to state law. FLI supports its efforts on a 2017 Supreme Court decision that preventing parents from choosing religious options where school choice is available violates the U.S. Constitution’s Free Exercise and Equal Protection Clauses. 
The First Liberty Institute has been representing high school football coach Joe Kennedy since 2015, after the Bremerton School District told him that he must stop praying after games. FLI initially sent a letter to the district explaining that school employees do not lose their private rights to express their religious beliefs when entering school property, and asked that Kennedy be accommodated with 15 seconds of silent prayer after games, once players cleared the field. After this accommodation was denied and Kennedy was terminated, FLI filed suit against the school district. The United States Court of Appeals for the Ninth Circuit ruled in favor of the school district and the U.S. Supreme Court declined to review the case in 2019. 
In 2019, the First Liberty Institute began its representation of Chick-fil-A in San Antonio. The San Antonio City Council voted to ban Chick-fil-A from its airport because of the company’s history of donating to Christian organizations. FLI claimed that this ban was blatant religious discrimination; a violation of the First Amendment, which protects organizations from hostile treatment because of the owner’s religious views; and a violation of the Texas Legislature’s First Amendment Defense Act. FLI submitted an amicus brief on behalf of Chick-fil-A in 2021. 
The First Liberty Institute represented the American Legion in response to a 2014 lawsuit filed by the American Humanist Association (AHA). AHA claimed that the Bladensburg WWI Veterans Memorial, commonly known as the “Peace Cross,” violated the First Amendment’s Establishment Clause. The U.S. Supreme Court heard the case in February 2019, and in June 2019, the Court upheld the constitutionality of the Bladensburg memorial. 
The First Liberty Institute is funded by donations from individuals, foundations, and corporations.
