The far-right party was forced to reduce its number of candidates for an upcoming regional election in eastern Germany. A state constitutional court said part of that decision was "highly likely illegal."
The far-right Alternative for Germany (AfD) party has won a partial legal victory after a constitutional court in Saxony overruled the state's decision to limit the party's number of candidates.
The state's electoral commission reduced the candidate list from 61 to 18 for state elections in September because the party only elected the first 18 candidates at the same party convention.
The prior restriction on the candidate list could have resulted in the party failing to fill all of its newly won seats in the state assembly. Based on current polls, the party might hope to win in the region of 30 seats in the parliament.
The head of the region's center-left Social Democrats (SPD), Henning Homann, said "the court has made an important decision because it protects democracy in Saxony."
His party later issued a statement saying it was "not satisfied" with the decision.
The constitutional court is expected to issue a final verdict in the case on August 16.
