What's with all this 'alleged' business?
If they got fined by the Commision, surely this was because, in the eyes of the Commision, they engaged in cartel behaviour. Not because they were alleged to have engaged in cartel behaviour.
IAKAL but during an ongoing investigation or court case wouldn't you throw in the word at every opportunity to prevent prejudice (not to mention arrest for contempt of court)? Since they've been fined, the investigation has concluded; couldn't you call them mad, scheming b*st*rds if you so wish?
Makes it sound like you have reason to doubt the Commision's conclusion...
