Here is the unpublished opinion in La Cuna De Aztlan Sacred Sites Protection Circle Advisory Committee v. Dept. of Interior.

An excerpt:

We conclude that the record, which includes declarations submitted by the Plaintiffs that provide little more than conclusory statements and which have not shown where the alleged sacred sites are located at the Ivanpah Project site, is insufficient to support Plaintiffs’ claim that the loss of access to the limited area taken by the Ivanpah Project imposes a substantial burden. Viewing the evidence in the light most favorable to the Plaintiffs, the Plaintiffs have not shown that they are either “forced to choose between following the tenets of their religion and receiving a governmental benefit,” or “coerced to act contrary to their religious beliefs by the threat of civil or criminal sanctions” as this court requires to establish a substantial burden under RFRA.
