Experts predicted that a flood of lawsuits would be filed after the Trump administration announced it would, for the first time since the enactment of the 1996 Helms-Burton Act, allow Americans to sue the Cuban government over property confiscated after Fidel Castro’s 1959 revolution.

But according to an analysis by The Daily Business Review, only four such lawsuits have been filed since May 2, when such litigation was allowed to proceed. The remarkably low number of lawsuits stands in stark contrast to the nearly 6,000 claims that have been certified by the U.S. Foreign Claims Settlement Commission.
