There is also the very critical issue of damages. To summarize, damages can be as high as three times the greater of (1) the value of the property when confiscated, plus interest at the weekly average one-year Treasury bill; and (2) the current value of the property; plus, in either case (1) or (2), legal fees and costs.
In the case of (1), interest compounds annually and accrues from the date the property was confiscated until the date the lawsuit is filed. Most of the property at issue was confiscated in the 1960s, so cumulative interest could be high.
