Coke's view was not put into practice, but was rejected by Lord Mansfield in 1774. The two doctrines were reconciled, with the Doctrine of Continuity prevailing in nearly all situations (except, for example, public property of the predecessor state) in Oyekan v Adele (1957). The first Indigenous land rights case under the common law, Mohegan Indians v. Connecticut, was litigated from 1705 to 1773, with the Privy Council affirming without opinion the judgement of a non-judicial tribunal. Other important Privy Council decisions include In re Southern Rhodesia (1919) and Amodu Tijani v. Southern Nigeria (Secretary) (1921). The former rejected a claim for aboriginal title, noting that: Some tribes are so low in the scale of social organization that their usages and conceptions of rights and duties are not to be reconciled with the institutions or the legal ideas of civilized society. Such a gulf cannot be bridged. Two years later, Amodu Tijani laid the basis for several elements of the modern aboriginal title doctrine, upholding a customary land claim and urging the need to "study of the history of the particular community and its usages in each case." Subsequently, the Privy Council issued many opinions confirming the existence of aboriginal title, and upholding customary land claims; many of these arose in African colonies. Modern decisions have heaped criticism upon the views expressed in Southern Rhodesia. Doctrinal overview Recognition The requirements for establishing an aboriginal title to the land vary across countries, but generally speaking, the aboriginal claimant must establish (exclusive) occupation (or possession) from a long time ago, generally before the assertion of sovereignty, and continuity to the present day. Content Aboriginal title does not constitute allodial title or radical title in any jurisdiction. Instead, its content is generally described as a usufruct, i.e. a right to use, although in practice this may mean anything from a right to use land for specific, enumerated purposes, or a general right to use which approximates fee simple. It is common ground among the relevant jurisdictions that aboriginal title is inalienable, in the sense that it cannot be transferred except to the general government (known, in many of the relevant jurisdictions, as "the Crown")although Malaysia allows aboriginal title to be sold between indigenous peoples, unless contrary to customary law. Especially in Australia, the content of aboriginal title varies with the degree to which claimants are able to satisfy the standard of proof for
