Formalism: demands strict adherence to the functional boundaries separating the
branches of government  and the understanding that, except for the provisions
expressly spelled out by the Framers, each branch should exercise its own powers.
Constitutional provisions are construed as marking boundaries from which the
courts can formulate ascertainable standards and thereby exercise their
constitutional role of safeguarding against the accretion of power. Look to
Marbury to support this. Lacks efficiency.
