Polish appeals court overturns ruling against Holocaust historians

Case has raised questions about freedom to research Poland's wartime past

A Polish appeals court has overturned a ruling against two leading Holocaust historians accused of defamation, in a closely watched case that raised questions about the freedom to research Poland's second world war past.

The civil case was brought against Prof Barbara Engelking and Prof Jan Grabowski for a book they co-edited about the complicity of Catholic Poles in the genocide of Jews during Nazi Germany's occupation of Poland.
