The Constitution provides for the Senate to exercise its “advice and approval” in the context of contractualization, an ambiguous phrase that presidents and senators have discussed since the creation of the nation. During the War of 1812, Delaware Senator James Bayard was a member of the delegation to negotiate the Treaty of Ghent. His presence raised the question of whether the senators on the negotiating team would make the Senate more supportive of approving the treaty or whether it would violate the separation of powers. This debate has been going on for generations without a solution. In the summer of 1787, the delegates of the Constitutional Convention debated the structure and powers of a new legislative body. One of the questions they asked was: Should the power of contracting be within the legislative or executive branch? According to the articles of Confederation, a treaty could be concluded with the agreement of nine of the thirteen states or two-thirds. Some delegates, such as Charles Pinckney of South Carolina, insisted that the Senate, where each state was represented on an equal footing, had the exclusive power to enter into contracts. Alexander Hamilton argued that the executive should exercise powers related to foreign relations and should therefore have the power to enter into contracts “with the Council and the approval of the Senate.” In the end, Hamilton`s argument proved to be the most convincing. If the power of foreign relations is really an exclusive federal power, with no role for the states, a logical consequence, the Supreme Court has decided that certain state laws that have insequential in foreign relations would not be valid even without a relevant federal policy. There is indeed a “dormant” power in external relations. However, the scope of this power remains undefined and its constitutional basis is debated by scientists. However, it was not until 1968 that the Court applied the general principle to invalidate a state law which, in the absence of established federal policy, encroached on the country`s external interests.
In Zschernig v. Miller503 the court struck down an Escheat law of Oregon that was to prevent the inheritance of citizens of communist countries. The law has conditioned the inheritance of non-resident aliens on proof that the United States Throughout American history, presidents have also entered into international agreements through agreements between Congress and the executive branch, which are ratified only by a majority of both houses of Congress, or through executive agreements entered into by the president alone in the exercise of his constitutional executive powers.  Although the Constitution does not explicitly propose an alternative to the contractual procedure referred to in Article II, Article I, Section 10 of the Constitution distinguishes between treaties (states cannot be concluded) and agreements (which states can conclude with the agreement of Congress).  The Supreme Court held that agreements between Congress and the executive and executive branch were valid, and they were common throughout American history. . . .
