To the Senate:
I respectfully return to the Senate, where it originated, the "act to authorize the Secretary of the Treasury to compromise the claims allowed by the commissioners under the treaty with the King of the Two Sicilies, concluded October 14, 1832," without my signature.
The act is, in my judgment, inconsistent with the division of powers in the Constitution of the United States, as it is obviously founded on the assumption that an act of Congress can give power to the Executive or to the head of one of the Departments to negotiate with a foreign government. The debt due by the King of the Two Sicilies will, after the commissioners have made their decision, become the private vested property of the citizens of the United States to whom it may be awarded. Neither the Executive nor the Legislature can properly interfere with it without their consent. With their consent the Executive has competent authority to negotiate about it for them with a foreign government--an authority Congress can not constitutionally abridge or increase.
ANDREW JACKSON.
