“the American system of checks and balances disperses federal lawmaking authority among multiple, overlapping political forums. As a result, federal policymaking power is shared: Congress is given the primary power to draft laws, subject to the president's veto and judicial review; the executive branch is given the primary power to implement laws, subject to congressional oversight and judicial review; and the courts have the primary power to interpret laws, subject to a variety of legislative and executive checks, including the appointment process, budgetary powers, and the passage of "overrides"-laws that explicitly reverse or materially modify existing judicial interpretations of statutes.”
