The federal returning officer and the polling institute Forsa are arguing in court over the so-called Sunday question.
The procedure will be decided "promptly", said a spokeswoman for the Wiesbaden administrative court on Friday of the German press agency.
"Business Insider" had previously reported on it.
The proceedings have been pending since September 7th.
The point of contention is the question that polling institutes regularly ask randomly selected citizens: "If there were elections to the Bundestag on Sunday, whom would they vote for?"
Forsa also asks whether someone has already voted by letter and if so, who.
Violation of Section 32 of the Federal Election Act?
According to the court, the Federal Returning Officer asked the institute, with reference to a fine, not to publish any poll results until the closing of the polling stations on September 26 at 6 p.m. in which answers from voters who have already cast their votes by postal vote have been processed ".
He refers to Paragraph 32 of the Federal Election Act, according to which the publication of voter surveys after voting is not permitted.
Forsa, on the other hand, is of the opinion, according to the court, that publishing the results before the election does not violate Section 32. The data would only be published “aggregated” with the other survey results, so that a mixture of responses from postal voters and voters occurs. The information provided by postal voters would not be shown separately.
