Interesting last three paragraphs with the opinion of a lawyer and legal scholar, Udo Vetter:
[Vetter] argued that the law had deliberately made it all but impossible for registry offices to block applicants from changing gender on the basis that they did not seem to be sincere. Nor, in Vetter’s view, can Liebich’s previous statements attacking the transgender rights movements be used as evidence of his deceit.
“Should the Halle district court approve the application from the Saalekreis, it would not just create Germany’s first case of [self-ID] reversal,” Vetter wrote. “It would above all send out a signal that the self-ID law actually is subject to a material check, against the explicit will of the people who made the law.
“An interpretation along these lines cannot be reconciled with the literal wording and classification scheme of the law. At the end of the day, it would mean the end of the newly-won liberty [to change genders at will].”
This might end up at the Constitutional Court yet.
