Question of immoral legal transaction, the rights to sell real estate and restitution (Dokonywanie transakcji dotyczących mienia ludności żydowskiej w okresie okupacji na wyzysk) - The fact that a certain type of exploitation is practised by a significant number of persons, so that a certain average "norm" of exploitation emerges, does not preclude the application of the usury provision of Article 42 RPR KZ. This provision should be applied in particular to transactions involving the property of the Jewish population during the German occupation, when the restrictions imposed by the occupiers meant that the prices of such property were unusually low.
