Burial Rites Mediation between Aboriginal Clans

A scenario
The body of the deceased from a remote community is in the mortuary in under the control of the Coroner
Family members contact the Coroner separately:

1. The father of the deceased  seek release of the body to be buried according to tradition on the land of the deceased birth.
2. The spouse of the deceased (who comes from another clan group) seeks the body of the deceased to be released on their land 

The above parties end up in conflict over who has the stronger legal authority as senior next of kin as an indigenous person
