- What it's about
The Court denied Tanamor-Steffan’s petition, leaving in place the Ninth Circuit’s refusal to issue a writ of mandamus or prohibition challenging the district court’s dismissal order. The denial did not resolve whether the lower courts’ legal or factual conclusions were correct.
Question presented
Whether the United States Court of Appeals for the Ninth Circuit erred in denying Petitioner’s petition for a writ of mandamus and/or prohibition, where the district court’s order of dismissal was based on a clearly erroneous interpretation of the law and/or facts, and where Petitioner has no other adequate means to attain the relief she seeks?
