I am so glad to read this. Last I had read on the case was that the traders were (outrageously) convicted of market manipulation: https://www.cnbc.com/2010/10/14/norwegians-convicted-for-out...

But you are right, they appealed and had their appeal upheld by the Supreme Courts: https://www.finextra.com/newsarticle/23677/norwegian-court-a...

I am so glad at the result.
