This paper illustrates the principle of checks and balances on which much of the Constitution is based. The founders believed it was necessary to distribute power among multiple branches of government and ensure that none of these branches became too powerful. This paper focuses in particular on limiting the power of the legislature. Hamilton claims that, in republican societies, the legislative branch of government is always the most powerful since it directly represents the voice of the people. In order to prevent this branch from completely monopolizing the government, the other branches must have means of constitutional “self-defense.”

1933 – 
1803 The impeachment trial of a U.S. Judge, John Pickering. He was the first federal official to have been removed from office upon conviction by impeachment on charges of drunkenness and unlawful rulings. Pickering’s behavior on the bench was often marked with “ravings, cursings, and crazed incoherences” brought on by drink and growing mental instability. President Jefferson suggested to Congress that Pickering’s bizarre behavior amounted to an impeachable offense. There was no other way to remove a federal judge who was no longer fit to serve but who refused to resign. In March 1803 the House of Representatives voted 45-8 to impeach Judge Pickering. The Senate convicted Pickering one year later, removing him from office. This was no small matter. The Constitution limited this power to the impeachable offenses of “treason, bribery, or other high crimes and misdemeanors.” Pickering may have been wholly unfit to serve on the bench, but he had not committed an impeachable offense. Some feared that if he could be removed for raving and cursing, then Congress would impeach other judges for political offenses.
