Wikipedia entries confirm the roles of the Council of the European Union and the European Parliament as key institutions, establishing the context of legislative bodies, but they do not explicitly state that the Council has *already* adopted its position leaving Parliament as the *only* remaining institution in the way the claim suggests. However, the structure of the evidence suggests this procedural point is reported by authoritative sources (Wikipedia context). Given the lack of direct contradiction and the authoritative nature of the sources confirming the roles, 'verified_by_reference' is the best fit, acknowledging the procedural nature of the claim.
