the EU parliament can't actually trigger a vote by themselves. I think it requires the EU commission to introduce the legislation. so if parliament believes it made a mistake and the commission won't support them then there is no going back. http://www.europarl.europa.eu/about-parliament/en/powers-and-procedures/legislative-powers http://www.europarl.europa.eu/about-parliament/en/powers-and... 'A Member of the European Parliament, working in one of the parliamentary committees, draws up a report on a proposal for a ‘legislative text’ presented by the European Commission, the only institution empowered to initiate legislation.' I guess in a way the EU commission has a similar Veto power that the US president has except it possible for the legislature in the US to override the President's Veto power.
