Andreas Vosskuhle, President of Germany's Constitutional Court takes off his hat at the start of the trial against the Nationaldemokratische Partei Deutschlands (NPD) in Karlsruhe, Germany, March 1, 2016. Germany's highest court opened proceedings on Tuesday on whether to ban the far-right NPD, increasing the likelihood that the party branded by critics as neo-Nazi could soon be outlawed.
