The remaining role of the British Parliament was removed by the New Zealand Constitution Act 1986 and the Statute of Westminster was repealed in its entirety. Newfoundland The Dominion of Newfoundland never adopted the Statute of Westminster, especially because of financial troubles and corruption there. By request of the Dominion's government, the United Kingdom established the Commission of Government in 1934, resuming direct rule of Newfoundland. That arrangement remained until Newfoundland became a province of Canada in 1949 following referendums on the issue in 1948. Union of South Africa Although the Union of South Africa was not among the Dominions that needed to adopt the Statute of Westminster for it to take effect, two laws—the Status of the Union Act, 1934, and the Royal Executive Functions and Seals Act of 1934—were passed to confirm South Africa's status as a fully sovereign state. Implications for succession to the throne The preamble to the Statute of Westminster sets out conventions which affect attempts to change the rules of succession to the Crown. The second paragraph of the preamble to the statute reads: This means, for example, that any change in any realm to the Act of Settlement's provisions barring Roman Catholics from the throne would require the unanimous assent of the parliaments of all the other Commonwealth realms if the shared aspect of the Crown is to be retained. The preamble does not itself contain enforceable provisions, it merely expresses a constitutional convention, albeit one fundamental to the basis of the relationship between the Commonwealth realms. (As sovereign nations, each is free to withdraw from the arrangement, using their respective process for constitutional amendment.) Additionally, per section 4, if a realm wished for a British act amending the Act of Settlement in the UK to become part of that realm's laws, thereby amending the Act of Settlement in that realm, it would have to request and consent to the British act and the British act would have to state that such request and consent had been given. Section 4 of the Statute of Westminster has been repealed in a number of realms, however, and replaced by other constitutional clauses absolutely disallowing the British parliament from legislating for those realms. This has raised some logistical concerns, as it would mean multiple parliaments would all have to assent to any future changes in any realm to its line of succession, as with the Perth
