Verity Algar ('When is restitution a bad thing? The case of Melanesian wood carvings', ARCA blog July 19, 2013) argues that "not all cultural groups want to re-possess their cultural heritage", or at least certain elements of it. She takes as her example Malanggan from Northern New Ireland, Papua New Guinea - wood carvings from Melanesia.
I find this a little odd. It is almost as though the author is suggesting that it is the collector who decides (should decide) for a native community. Surely "restitution"/"repatriation" should be a result of respecting a request of the people whose heritage it is, rather than something graciously offered or even insisted upon by the collectors who have it.
