By his inviting a foreign leader to address Congress, John Boehner deliberately dealt in foreign policy and thus violated the "Logan Act", thus usurping the powers of the presidency of the United States.
In so doing, Boehner also deliberately violated the "separation of powers" clause in the US Constitution.
By law, he must now be tried by Congress, and forced to resign.
Under the "Logan Act" of 1799, (1 Stat. 613, 30 January 1799, currently codified at 18 U.S.C. § 953) Executive power to engage in Foreign Policy is ONLY vested in the President of the United States of America.
The Logan Act (1 Stat. 613, 30 January 1799, currently codified at 18 U.S.C. § 953) specifically forbids any unauthorized citizens from negotiating with foreign governments.
The Act is intended to prohibit United States citizens without authority from interfering in relations between the United States and foreign governments.
It was passed in 1799 and last amended in 1994.
Violation of the Logan Act is a felony, punishable under federal law with imprisonment of up to three years.
§ 953. Private correspondence with foreign governments.
Any citizen of the United States, wherever he may be, who, without authority of the United States, directly or indirectly commences or carries on any correspondence or intercourse with any foreign government or any officer or agent thereof, with intent to influence the measures or conduct of any foreign government or of any officer or agent thereof, in relation to any disputes or controversies with the United States, or to defeat the measures of the United States, shall be fined under this title or imprisoned not more than three years, or both.
This section shall not abridge the right of a citizen to apply himself, or his agent, to any foreign government, or the agents thereof, for redress of any injury which he may have sustained from such government or any of its agents or subjects.
1 Stat. 613, January 30, 1799, codified at 18 U.S.C. § 953 (2004).
