Although the Commission convicted Luzin, he was neither expelled from the Academy nor arrested, but his department in the Steklov Institute was closed and he lost all his official positions. There has been some speculation about why his punishment was so much milder than that of most other people condemned at that time, but the reason for this does not seem to be known for certain. Historian of mathematics A.P. Yushkevich speculated that at the time, Stalin was more concerned with the forthcoming Moscow Trials of Lev Kamenev, Grigory Zinoviev and others, whereas the eventual fate of Luzin was of a little interest to him.
