I think historians disagree over whether the decision was handed down by the Ural Soviet or by Lenin, Trotsky, and Svederlov. It's possible that the decision was made by the Ural Soviet and then signed off on by one of the three people, which further muddies the waters.

But man, imagine if it was the Soviet. Imagine being a peasant or a clerk at the meeting and the next agenda item is executing the Royal Family.
