Presidency scholars suggest that the federal bureaucracy has become "presid
entialized" and that the federal agencies have become a primary tool for pr
esidential policy implementation. However, in its review of federal agency
litigation, the Supreme Court stands as an important monitor of executive b
ureaucratic action. Here, the conditions under which Supreme Court justices
choose to facilitate executive bureaucratic action are assessed. This stud
y tests the proposition that Supreme Court justices' voting decisions to su
pport the president's bureaucratic agents are conditioned upon theoreticall
y interesting extra-legal factors. Logistic regression analysis was conduct
ed on justices' votes from Supreme Court cases involving cabinet and indepe
ndent agencies during the years 1953-1995. The results indicate that Suprem
e Court justices' voting decisions to favorably review bureaucratic actions
are influenced by extra-legal factors including attitudinal, political, an
d external concerns.
