Regulating government ('s share): the fifty-percent rule
of the federal constitutional court in Germany

Abstract Some numbers in the political sphere seem to be chosen rather arbi-
trarily. One example might be the rule set out by the Second Senate of the German
Federal Constitutional Court in 1995 that the overall tax load on assets must be
limited to 50% of the yield on those assets. This rule was understood by many as a
general principle for taxation. The article first sketches the socio-political climate
under which the rule originated: a rise of neo-liberal thought met with the inability
of the political institutions to reform the German welfare state with its ever-growing
expenses. The Constitutional Court's intervention is interpreted as a reaction to this
stagnation in politics. An analysis from the perspective of Constitutional Law,
however, reveals that the 50% rule cannot be convincingly based on the German
Basic Law, and instead must be seen as a political move of the Court. But this move
did not follow an economic rationality, either; for an optimal government's share
can only be determined in relation to the economic performance of a country and
not by fixing it generally at a maximum of 50% of GDP. The demise of the 50% rule
already began four years later. In 2006, finally, the Senate moved away from the
individual rights-based approach of 1995 to a more general assessment, taking also
into account an increasingly globalized tax competition. The reason for this clear-
cut change in the Court's jurisprudence can be found in a change of the socio-
political and institutional parameters, thus witnessing to the effect of the political
climate on court decisions. The analysis also shows that the rule was created and
abandoned only on the basis of an introverted legal discussion, economic
