As far as I recall, in Guatemala, United Fruit had undervalued the worth of their land to reduce their taxes. So when they were compensated for the nationalization of their land based on their own valuation, they said that they were under compensated. United Fruit complains helped trigger the US intervention.
My understanding is that courts ruled that some (though not all) of the 2007 expropriations were made without proper compensation.
It's fair because privatization of public good is generally not made with proper compensation either.
Compensation is complicated.
