German officials are launching a new drive to have the country's main far-right party banned, insisting that they've learned their lessons from the failure of a similar effort a decade ago.

Parliament's upper house, which represents Germany's 16 state governments, planned to submit its application to ban the National Democratic Party to the country's highest court Tuesday.

Germany's states allege that the party promotes a racist, xenophobic and anti-Semitic agenda in violation of the country's constitution.

In 2003, the Federal Constitutional Court rejected an attempt to ban the party because paid government informants within the group were partially responsible for the evidence against it. The Lower Saxony state interior minister, Boris Pistorius, told ARD television officials are certifying that "none of the sources are contaminated by informants" this time.
