Norwegian lacked CII/III approval their first year in operation. Didn't stop them from executing those approaches all winter long at Oslo. It was obvious to everyone what was going on, ATC, other operators, but there were no repercussions.
If you want no trouble get a Norwegian AOC as a Norwegian start up carrier. You will be the darling of press and the authorities and looking the other way is SOP.
Oh, and they didn't bother to de-ice that first winter, either. Too expensive.
