Peter Nielsen was not at fault for the crash; Skyguide's malpractices crippled his ability to control the airspace and that is why the planes crash. The courts ruled that Skyguide administration is responsible.
"Why was the air traffic controller not already in jail himself for criminal negligence? The Russian man may have killed a man. But how many did the victim kill by not properly doing his job?"
He WAS doing his job properly. Skyguide crippled him in this way: * Often one controller manned two workstations several feet apart. Why did Skyguide let this happen? * Maintenance men knocked out the phone system and disabled the visual collision alert warning system
So when Nielsen realized he was swamped as he had to help an Aero Lloyd land, he could not contact outside help (phone is dead). When he realized that BTC2937 and DHL611 were nearing each other, he asked BTC to descend when its TCAS told it to climb. As systems were down DHL611 could not tell Nielsen that it was also descending. Nielsen did not and could not know what the TCAS said for BTC2937.
