It would be in the EU's interest to start an investigation of Karel De Gucht to determine if this person is bribed and if these proceedings is a result of corruption. The EU would be wise to do so for its own business sake and before it's perception as a democratic body is tarnished in favour of a US-led corrupt legislative-body.
If the EU loses its perception as democratic, chances are that the rich and populous democracies which funds it will be forced to stop doing so. If it's one thing the EU cannot afford right now, that is one of them.
