"more influence" isn't good enough in a democracy. These are supposed to be the people's representatives. Calling the treaty a "constitution" without it guaranteeing civil rights and true democracy was an insult to the people, and quite rightly buried by those that were allowed to vote on it.

The EP is a joke, a political instrument played by the same people that supported ACTA, and is now being used as a way to get out of it.

Which in all makes it more significant. In reality, it isn't so much that the EP stopped ACTA, but the people who first supported it (people with actual power) that have changed their minds, even though most of them can't admit so directly because of international (read "US") relations. In the long term, that (changing minds) is the bigger victory.
