A Massachusetts-based animal rights group has filed a brief with the Connecticut Appellate Court seeking to overturn a ruling by a Superior Court judge, who found the group’s petition for a common-law writ of habeas corpus to remove three elephants from a Goshen petting zoo was “wholly frivolous.”

The Nonhuman Rights Project’s 49-page brief, filed Monday afternoon, addressed only two issues in Litchfield Superior Court Judge James Bentivegna’s ruling: that the writ of habeas corpus was wholly frivolous and that the group lacked standing to seek the release of elephants Beulah, Minnie and Karen to a sanctuary.
