CHAP. V] TREATY RELATIONS 1105 
accepts a treaty to pass any legislation necessary to give it 
full force, and this has often been done, e.g. by the North 
American Colonies to carry out the provisions of the Extra- 
dition Treaty of 1842, of the Reciprocity Treaty of 1854, and 
of the Treaty of Washington of 1871, and by Canada in 19086, 
1908 and 1911 to confirm the Japanese and French treaties. 
The Imperial Government has also often legislated to sup- 
plement, Colonial legislation, as in the case of the Anglo- 
American Treaties of 1854 and 1871, and the Anglo-French 
Treaty of 1904. In the case of Newfoundland an Imperial 
Act to override Colonial legislation was proposed in 1891} 
and only withdrawn on an undertaking being given by the 
Colonial Government that Colonial legislation would take 
place, and an Order in Council of September 9, 1907,% was 
actually passed, under the Imperial Act of 1819, to suspend 
the operation of certain Colonial legislation which was in- 
consistent with a modus vivendi of September 6, 1907, with 
the United States. This Order in Council was revoked in 
1908 on the acceptance by the Colony of a modus vivends 
pending the submission of the questions at issue with the 
United States to arbitration. 
It is, of course, in each case a question of interpretation 
how far treaties extend to the Dominions. Thus Her 
Majesty’s Government in 18752 held that British Columbia 
was not entitled to the benefits of the Treaty of Washington 
of 1871, as it had become part of the Dominion of Canada 
subsequent to that date. On the other hand, general treaties 
would clearly, on the accepted principle of international 
law, apply to territories acquired subsequent to the date of 
the treaty, as, for example, the Transvaal and the Orange 
River Colony. Certain difficulty might arise in such a case, 
for normally these Colonies, as self-governing Colonies, 
would have been given the option of adhering to treaties of 
2 commercial character. whereas as it was thev fell under the
