It is patent that under the new constitution the Irish Parliament and, under ordinary circumstances, the Irish Parliament alone will legislate for Ireland.  For the Irish Parliament can, subject to certain Restrictions,[13] pass any law whatever ’for the peace, order and good government of Ireland, in respect of matters exclusively relating to Ireland or some part thereof’[14]; and, subject to the same Restrictions, may repeal any law which, before the Home Rule Bill becomes law, is in force in Ireland.  Under the new constitution the Irish Parliament and not the Imperial Parliament will, it is clear, as a rule legislate for Ireland.  Under the new constitution the Irish Parliament may enact a Coercion Act, applying say to Ulster, or may repeal the existing Crimes Act.  It may abolish trial by jury[15] altogether, put any restraints it sees fit on the liberty of the press, or introduce a system of administrative law like that which exists in France, but is totally foreign to English notions of jurisprudence.

Under the new constitution, again, the financial relations of Great Britain and Ireland are made the subject of an elaborate arrangement which may fairly be called a contract[16].  Ireland takes over certain charges[17], and speaking very generally, whilst all the duties of customs levied in Ireland are collected by and paid over to the Exchequer of the United Kingdom, as Ireland’s contribution to Imperial expenditure, all the other taxes are, as a general rule, paid over to the Irish Exchequer.  The justice or the policy of these financial arrangements is for my present purpose immaterial.  All that need be observed is that the ordinary taxation of Ireland passes from the hands of the Imperial Parliament into the hands of the Irish Parliament, and that under the new constitution this arrangement is a settlement which the Imperial Parliament is morally bound to respect for a period of at least fifteen years[18].

In Ireland therefore the new constitution abolishes the effective exercise of authority by the Imperial Parliament in matters of administration, in matters of legislation, in matters of finance; every concern which affects the daily life of Irishmen will be under the control of the Irish Cabinet and the Irish Parliament.  The relation of the Imperial Parliament towards Ireland will not be the relation which it now occupies towards the whole United Kingdom, and which under the new constitution it will still occupy towards Great Britain.  The Imperial Parliament, it is true, retains considerable reserved powers; what are the effect and nature of these powers shall be considered in its due place.  The matter upon which I now insist is simply this:  the new constitution does in any case transfer the effective government of Ireland from the Imperial Parliament to the Irish Parliament.  The authority reserved to the Imperial Parliament may be termed supremacy, or sovereignty, or may be described by any other fine-sounding name which we are pleased to use, but the fact remains unaltered that, as long as the new constitution stands and works, the Imperial Parliament will not govern Ireland in the sense in which it governs England and Scotland, and that such authority as it exerts in Ireland will be analogous not to the power which it now exercises there, but to the influence which it possesses in Canada or in New Zealand.[19]
