Input: Read this: Once inside the Rotunda for the Charters of Freedom, there are no lines to see the individual documents and visitors are allowed to walk from document to document as they wish.

As a result, all filming, photographing, and videotaping by the public in the exhibition areas has been prohibited since February 25, 2010.

Output: unanswerable

Input: Read this: Congress may establish "legislative courts," which do not take the form of judicial agencies or commissions, whose members do not have the same security of tenure or compensation as the constitutional court judges. Legislative courts may not exercise the judicial power of the United States. In Murray's Lessee v. Hoboken Land & Improvement Co. (1856), the Supreme Court held that a legislative court may not decide "a suit at the common law, or in equity, or admiralty," as such a suit is inherently judicial. Legislative courts may only adjudicate "public rights" questions (cases between the government and an individual and political determinations).
Question: Which type of courts are established by Hoboken Land & Improvement CO.?

Output:
unanswerable
