| Plenty. Some recent examples: https://www.reuters.com/world/europe/european-parliament-scr... https://agenceurope.eu/en/bulletin/article/13274/20 https://www.thejournal.ie/emissions-trade-system-fit-for-55-... (Somewhat unsurprisingly, being currently dominated by right-wing parties, it happens often on "green" legislation...) It doesn't happen every day simply because 1) MEPs typically don't want to be seen as "Mr. No", and 2) plenary votes are the end of a long legislative process, involving several steps; the Commission will typically not bring legislation to the floor if it understands, in previous committees, that it will likely be voted down. The process is roughly this: EU Council (i.e. national governments) agree that "we should really do something about X"; the Commission drafts legislation to that effect, and brings it to Parliamentary committees; MEPs provide feedback and instructions on how to change things; Commission decides if the changes are acceptable, and if not they go back to Council asking "is this still ok if we do it in XY way?"; and back and forth they go, until the Commission decides to either withdraw it or put it to a plenary vote (in which case it's typically in a shape acceptable to Parliament, because nobody likes losing). |
It's not quite clear what happens next - the Council of ministers may apparently decide to continue working on the legislation regardless of the Parliament's vote.
In other words - it is not evidence of an "ultimate veto power"
