Not later than December 31, 1996, the Secretary of the Smithsonian Institution shall provide a written summary that contains a summary of unassociated funerary objects, sacred objects, and objects of cultural patrimony (as those terms are defined in subparagraphs (B), (C), and (D), respectively, of section 3001(3) of title 25, based upon available information held by the Smithsonian Institution. The summary required under this section shall include, at a minimum, the information required under section 3004 of title 25.
If a known lineal descendant or an Indian tribe or Native Hawaiian organization requests the return of Native American unassociated funerary objects, sacred objects, or objects of cultural patrimony pursuant to this subchapter and presents evidence which, if standing alone before the introduction of evidence to the contrary, would support a finding that the Smithsonian Institution did not have the right of possession, then the Smithsonian Institution shall return such objects unless it can overcome such inference and prove that it has a right of possession to the objects.
Any museum of the Smithsonian Institution which repatriates any item in good faith pursuant to this subchapter shall not be liable for claims by an aggrieved party or for claims of fiduciary duty, public trust, or violations of applicable law that are inconsistent with the provisions of this subchapter.
Nothing in this section may be construed to prevent the Secretary of the Smithsonian Institution, with respect to any museum of the Smithsonian Institution, from making an inventory or preparing a written summary or carrying out the repatriation of unassociated funerary objects, sacred objects, or objects of cultural patrimony in a manner that exceeds the requirements of this subchapter.
