WHEREAS, by an act of the last session of this present parliament, (intituled, An act to repeal an act, made in the sixth year of the reign of his late majesty King George the First, entitled, An act for the better securing the dependency of the kingdom of Ireland upon the crown of Great Britain,) it was enacted That the said last-mentioned act, and all matters and things therein contained, should be repealed: and whereas doubts have arisen whether the provisions of the said act are sufficient to secure to the people of Ireland the rights claimed by them to be bound only by laws enacted by his Majesty and the parliament of that kingdom, in all cases whatever, and to have all actions and suits at law or in equity, which may be instituted in that kingdom, decided in his Majesty’s courts therein finally, and without appeal from thence: therefore, for removing all doubts respecting the same, may it please your Majesty that it may be declared and enacted; be it declared and enacted by the king’s most excellent majesty, by and with the advice and consent of the lords spiritual and temporal, and commons, in this present parliament assembled, and by the authority of the same, That the said right claimed by the people of Ireland to be bound only by laws enabled by his Majesty and the parliament of that kingdom, in all cases whatever, and to have all actions and suits at law or in equity, which may be instituted in that kingdom, decided in his majesty’s courts therein finally, and without appeal from thence; shall be, and it is hereby declared to be established and ascertained for ever, and shall, at no time hereafter, be questioned or questionable.
II.
