Daily Journal:

There are no explanations, and, in fact, there cannot be any. The judge is in the deliberation room. He said that the announcement was postponed, and that was all. The last time the verdict was announced in the Meshchansky Court, it was exactly the same: the announcement of the negotiations was postponed from April 27 to May 16, and we were not given any official explanation either. The only official reason for postponing a sentence is if the judge did not have time to write it. There simply cannot be any other reasons. You can assume anything, everyone is free to conjecture whatever he considers necessary.
