U.S. Supreme Court
Hazelton v. Sheckells, 202 U.S. 71 (1906)
Hazelton v. Sheckells
Argued April 12, 1906
Decided April 23, 1906
202 U.S. 71
Every part of the consideration for a contract goes equally to the whole promise, and if any part of it is contrary to public policy, the whole promise falls.
A contract to deliver property at an agreed price within the duration of specified session of Congress, it being understood that a part of the consideration is that the person to whom the property is to be conveyed is to endeavor to sell it to the United States and to procure legislation to that end -- he not being under obligation to take and pay for the property -- is void as against public policy, and specific performance will not be enforced.
The facts are stated in the opinion. chanrobles.com-red
