FRANKFURT, Nov 19 Germany defended its nuclear
fuel tax on Tuesday after a Hamburg court referred a complaint
by power companies RWE and E.ON to the
highest EU court.
The Hamburg Financial Court said it doubted whether the levy
was compatible with European law, strengthening the hand of the
utilities who say they have paid 3 billion euros ($4 billion)
since the tax was introduced in 2011.
But Berlin says it is confident that it has not overstepped
its powers. "The German Finance Ministry expects that a decision
by the European Court of Justice will confirm this
interpretation of the law," the ministry said in a statement.
The levy requires firms to pay 145 euros per gram of nuclear
fuel each time they exchange a fuel rod, usually about twice a
year. The court said its ruling did not absolve the utilities of
their obligation to keep paying the tax.
The case is prominent because of the size of the charges,
which were introduced to boost state coffers, and because the
tax is one topic in current coalition talks between Chancellor
Angela Merkel's conservatives and the Social Democrats, some of
whom want to increase the levy and others the duration of the
tax, due to expire in 2016.
The tax also reflects Germany's growing scepticism about
nuclear power, which it is set to phase out completely by 2022.
E.ON WANTS MONEY BACK
"The court followed the legal argument presented by E.ON and
shared doubts about the compatibility of the nuclear tax fuel
law with that of the EU," E.ON said in a statement to Reuters.
It said it would consider seeking a temporary moratorium on
the payments, as well as reimbursements.
RWE - which had together with E.ON complained to
the Hamburg court about the tax payable for the Emsland reactor
that they operate jointly, adding to a string of similar local
cases - will study the decision and then comment on its next
steps, a spokesman for RWE said.
The Hamburg court had in January already sent a similar case
to Germany's Federal Constitutional Court in Karlsruhe, which
has not yet dealt with it.
A tribunal in Munich has expressed similar doubts on the
compatibility of the levy with EU law in a comparable case,
while a court in the southern city of Freiburg rejected such a
complaint from Germany's other nuclear operator, ENBW.
The utilities argue that the Finance Ministry is not
formally entitled to collect the tax as its remit does not
stretch to the sector, only to taxes on personal consumption.
The European case is likely to focus more closely on
equality and property issues.
Utilities shares have gained in recent days on the prospect
of the EU court being called upon. By 1505 GMT on Tuesday, RWE
was down by 1.06 percent and E.ON was down 0.57 percent,
compared with a 0.22 percent decline in Germany's blue-chip DAX
($1 = 0.7394 euros)
