Aronow v. United States was the first case to challenge the inclusion of "In God We Trust" on U.S. currency.[1]
In that case, Stefan Ray Aronow challenged the constitutionality of the motto and its placement on U.S. currency and coinage.[2] In 1970 the United States Court of Appeals for the Ninth Circuit held that the plaintiff did not have standing as a taxpayer, but set aside the question of standing to rule on the merits of the case.[3] The Court ruled: "It is quite obvious that the national motto and the slogan on coinage and currency 'In God We Trust' has nothing whatsoever to do with the establishment of religion. Its use is of patriotic or ceremonial character and bears no true resemblance to a governmental sponsorship of a religious exercise."[1] The Supreme Court of the United States had declined to hear the appeal.[4]
A similar decision was reached by the Fifth Circuit in Madalyn Murray O'Hair vs W. Michael Blumenthal in 1979, which affirmed that the "primary purpose of the slogan was secular."[4] In addition, Aronow v. United States was referenced in the 2002 case of Elk Grove Unified School District v. Newdow.
