The regional court in the eastern German city of Halle is set to announce its verdict on Tuesday in the trial of Germany's far-right Alternative for Germany (AfD) politician Björn Höcke, accused of using a prohibited Nazi slogan.
The evidence collection process remains ongoing, with pending closing statements from both the prosecution and defence.
However, according to the presiding judge the judgement could be announced on Tuesday, the final scheduled trial date.
The public prosecutor's office accuses the leader of the Thuringian AfD state party and parliamentary group of having knowingly used a banned slogan of the Sturmabteilung (SA), or Storm Troopers, a Nazi paramilitary group commonly referred to as the "brownshirts."
Höcke, a former history teacher, has denied that he had knowingly used the slogan.
The 52-year-old is likely to face a financial penalty at most.
The AfD politician wants to stand as his party's top candidate in the state elections in Thuringia on September 1.
