The claim you refer to is in the region of 80 billions this article confirms, Ukraine to lay claim for Soviet Heritage, yet it is not known what claim related to Soviet Heritage Crimea will make nor if Crimeans will engage in a massive nation wide class action for compensation following the horror of the 1954 Supreme Soviet Presidium decision and the degrading treatment and psychological distress they experienced for decades as Russians in the hands of the Ukraine soviet. Given the circumstances and the horror Crimeans went through feeling rejected from what we all hold dearly, they did and do, the perspective to do so again was seen alright as soon as the referendum results were known, the 80 billions deposit at the USSR state bank looks pale in comparison to what the courts may order I would think.
