The flight was cleared to land on runway 27R but instead landed on taxiway M, which is situated immediately to the north and parallel to runway 27R. The runway lights for 27R were illuminated; the localizer and approach lights for 27R were not turned on.[my italics]
Sounds like quite a setup for a mishap to me. I think this was exactly the scenario when I landed on 27R at night a couple of years ago.
Wonder how the line check went...
