The posts before this seem to give the accurate details about postponing the verdict for a month. The Germans have a witness who says he's in the Iranian secret service and knew about 9/11 before it happened.
The German Feds submitted extensive manuscripts to the court within the last few days, which the court used as a reason to delay the verdict and return to evidence gathering phase for 30 days.
Here's my translation of what I think the main gist of the article (linked in post #3) and its description of the secret witness is:
The trial could take a new turn with this.. [information from earlier in the article]. The state attorneys found a man who claims to have been a high ranking member of the Iranian secret service for many years. In this function he had heard of the September 11 planning in its preliminary stages, had seen several Al-Qaida leaders in Iran and also known some of the suicide pilots from Germany by name. Indeed, only the German Federal Attorneys know the name of the man so far, but he wants to testify in court with the guarantee he remains anonymous..
Witness: Iran actively participated in September 11th
According to the interrogation notes, the secret service agent claims Iran had been actively involved in the planning of September 11th; it also mentions Mzoudi's name several times from page eleven of the notes on. He had learned from Iranian friends from within the secret service apparatus that the defendant was to have been killed by terrorists after his release in December 2003. The reason: In Iran, they suspect Mzoudi cooperated with western secret services or would be spied on after his release.
In the view of the states' attorneys, the testimony proves again that Mzoudi must very well have been a member of the Hamburg cell and therefore, shall have been liquidated as a carrier of confidential information and as a potential traitor. Other statements of the new witness incriminate Mzoudi deeply, as well. Such as, he reported that he had heard the name Mzoudi as the responsible party for the logistics of September 11th. The Moroccan had been responsible for the "design and the dispatch of information to intermediaries", "since he was well versed with codes".
end translation....
This article tries, however, to attempt to show how well the testimony of this mysterious Iranian fits into the framework the German feds have built around Mzoudi's actions. This testimony, if true, ties up all the loose ends into a tidy package. Mzoudi was a go-between, but he couldn't be placed in any specific role until they learned he was the one who handled the code. The witness's testimony fit the Fed's existing case so well they feel it is credible.
The court has to judge the witness's credibility for themselves, now.
That's my take, anyway.
