PhDThis thesis explores the contribution of the US Supreme Court
(USSC) and the European Court of Justice (ECJ) in the vertical and
horizontal allocation of power. Said differently, it answers the two
following questions: How do both Courts draw the line between the realm
of politics and judicial process? How do they allocate power between the
Union and its component States? After examining standing, the political
question doctrine, negative and positive integration and liability in damages
on both sides of the Atlantic, it is concluded that both Courts should not
always look for “substantive” constitutional benchmarks. The reason lies in
that sometimes the latter may turn to be either questions deemed too
political for judicial resolution or insufficient to control congressional or
Community legislative powers. Additionally, the judicial department should
also pay due regard to a “process” review. This type of review would
operate at two levels. At first stage, Courts should solve flaws in the
procedure by which the political institutions adopt their decisions. For
instance, this would be the case where procedures neglect “discrete and
insular” minorities, or where they entrench incumbent political majorities.
Thus, judicial review would be principled upon understanding “democracy”
as an intangible value that cannot succumb to majoritarian pressures. At a
second stage, Courts should also examine whether, in their deliberations,
political actors pay due account to all interests at stake, particularly, to those
not represented in the political process
