In a dispute with the Saarland Greens, the former state chairman Hubert Ulrich suffered two defeats.
The 63-year-old wanted the Saarbrücken regional court to prohibit a party conference planned for Saturday by means of an injunction - and was defeated.
The invitation to the state party conference was not obviously illegal or illegal, the court announced on Tuesday in Saarbrücken.
The competent state arbitration court of Rhineland-Palatinate had previously forbidden the state board of the Saar-Greens from submitting the state list for the federal election with Ulrich as the top candidate.
There were violations during the installation.
The dispute goes back to resolutions of the Saar-Grünen party congress on June 20.
At that time, the candidate for first place on the state list for the federal election had failed, and the party congress decided that, contrary to the women's statute, a man could run - Ulrich was elected.
This had led to resignations in the state executive.
Ulrich's critics now want by-elections in the state board on Saturday - and they are pressing for a new list for the federal election without Ulrich in the top spot.
Several media reported on Tuesday that the 63-year-old had announced that he would renounce the top candidacy after his defeats.
The provisional Greens state manager Nadja Doberstein told the German press agency that Ulrich had informed her that he would no longer run for a place on the new state list on Saturday.
"He accepts the defeat, he saw it from a sporting point of view," added Doberstein.
Ulrich wants to continue to participate in the state party conference on Saturday in Saarbrücken.
Green chancellor candidate Annalena Baerbock had also criticized Ulrich's original election.
She said: “We have a women's quota in our party for good reason.” And: “We wanted it differently.” The Saar Greens are not represented in the state parliament.
