The reasons behind the idea of appointing the Supreme Justices for life are long gone.In a democracy, no person holding a political position should be appointed for life
The Supreme Court, another usurper of Congress constitutional functions
The Founding Fathers in their wisdom made the "Separation of Powers" one of the pillars of American democracy. The US Constitution clearly and unequivocally stipulates that "All legislative powers herein granted shall be vested in a Congress of the United States, which shall consist of a Senate and a House of Representatives."
There have been historically a few cases when the Executive Power usurped the authority of the Legislative Power , but our current president arrogantly made it a habit and , without hesitation, violated the Constitution when it suited his political aims. Experts have tallied about a dozen of such acts. Here are a few of the most flagrant and inexplicable unilateral edicts : he unilaterally allowed one-year grace period and delayed implementation of employer mandate (Obamacare) ; he unilaterally waived the requirement of work for receiving welfare (1996 law) ; he unilaterally provided federal benefits to illegal aliens and granted deferred action on deportation that favors four to five million illegal aliens.
