Dear Nicolas, This is an interesting question and undoubtedly somewhere in Russia there are records of these decisions made in the name of Law. As documents go, I doubt that the Bolsheviks would have gotten rid of any evidence that proves Tsarism had the power to kill, beyond the law of the Courts. That is what I would like to know -- what was the relationship of Nicholas' decisions and the decisions made thru the courts. I read a lot of Dostoevsky this year and was so surprised at how much more developed the trial system was in Russia, mid-19th century, than I expected. It may be that almost all non-political defendants faced the decision of jury/judge, but political agitators faced a more amorphous law of the Government. There is the purported story of Nicholas being contacted by (Benckendorff?) after Nicholas had 'retired' for the day, and deciding to commute a death sentence as the prisoner was terminally ill.
Actually what interests me most about this question is how easily Westerners can judge a Tsar for using the death penalty or prison to handle political prisoners. It is horrible to consider. But I cannot imagine being Tsar and trying to maintain some type of order amid all of the sweeping political and economic changes happening in Russia after 1900. It is that 'walk in a man's shoes' issue once again -- how to be a Liberal at that time without getting into trouble, how to be a Tsar at that time without losing control of the entire country.
