The amendment read, in part: “The courts shall not look to the legal precepts of other nations or cultures. Specifically, the courts shall not consider international law or Sharia law.”

Backers argued that the amendment intended to ban all religious laws, that Islamic law was merely named as an example and that it wasn’t meant as a specific attack on Muslims. The court disagreed.

“That argument conflicts with the amendment’s plain language, which mentions Sharia law in two places,” the appeals court opinion said.
